+
+
+========
+OVERVIEW
+========
+
+There are several parts to the security check performed by Linux when one
+object acts upon another:
+
+ (1) Objects.
+
+ Objects are things in the system that may be acted upon directly by
+ userspace programs. Linux has a variety of actionable objects, including:
+
+ - Tasks
+ - Files/inodes
+ - Sockets
+ - Message queues
+ - Shared memory segments
+ - Semaphores
+ - Keys
+
+ As a part of the description of all these objects there is a set of
+ credentials. What's in the set depends on the type of object.
+
+ (2) Object ownership.
+
+ Amongst the credentials of most objects, there will be a subset that
+ indicates the ownership of that object. This is used for resource
+ accounting and limitation (disk quotas and task rlimits for example).
+
+ In a standard UNIX filesystem, for instance, this will be defined by the
+ UID marked on the inode.
+
+ (3) The objective context.
+
+ Also amongst the credentials of those objects, there will be a subset that
+ indicates the 'objective context' of that object. This may or may not be
+ the same set as in (2) - in standard UNIX files, for instance, this is the
+ defined by the UID and the GID marked on the inode.
+
+ The objective context is used as part of the security calculation that is
+ carried out when an object is acted upon.
+
+ (4) Subjects.
+
+ A subject is an object that is acting upon another object.
+
+ Most of the objects in the system are inactive: they don't act on other
+ objects within the system. Processes/tasks are the obvious exception:
+ they do stuff; they access and manipulate things.
+
+ Objects other than tasks may under some circumstances also be subjects.
+ For instance an open file may send SIGIO to a task using the UID and EUID
+ given to it by a task that called fcntl(F_SETOWN) upon it. In this case,
+ the file struct will have a subjective context too.
+
+ (5) The subjective context.
+
+ A subject has an additional interpretation of its credentials. A subset
+ of its credentials forms the 'subjective context'. The subjective context
+ is used as part of the security calculation that is carried out when a
+ subject acts.
+
+ A Linux task, for example, has the FSUID, FSGID and the supplementary
+ group list for when it is acting upon a file - which are quite separate
+ from the real UID and GID that normally form the objective context of the
+ task.
+
+ (6) Actions.
+
+ Linux has a number of actions available that a subject may perform upon an
+ object. The set of actions available depends on the nature of the subject
+ and the object.
+
+ Actions include reading, writing, creating and deleting files; forking or
+ signalling and tracing tasks.
+
+ (7) Rules, access control lists and security calculations.
+
+ When a subject acts upon an object, a security calculation is made. This
+ involves taking the subjective context, the objective context and the
+ action, and searching one or more sets of rules to see whether the subject
+ is granted or denied permission to act in the desired manner on the
+ object, given those contexts.
+
+ There are two main sources of rules:
+
+ (a) Discretionary access control (DAC):
+
+ Sometimes the object will include sets of rules as part of its
+ description. This is an 'Access Control List' or 'ACL'. A Linux
+ file may supply more than one ACL.
+
+ A traditional UNIX file, for example, includes a permissions mask that
+ is an abbreviated ACL with three fixed classes of subject ('user',
+ 'group' and 'other'), each of which may be granted certain privileges
+ ('read', 'write' and 'execute' - whatever those map to for the object
+ in question). UNIX file permissions do not allow the arbitrary
+ specification of subjects, however, and so are of limited use.
+
+ A Linux file might also sport a POSIX ACL. This is a list of rules
+ that grants various permissions to arbitrary subjects.
+
+ (b) Mandatory access control (MAC):
+
+ The system as a whole may have one or more sets of rules that get
+ applied to all subjects and objects, regardless of their source.
+ SELinux and Smack are examples of this.
+
+ In the case of SELinux and Smack, each object is given a label as part
+ of its credentials. When an action is requested, they take the
+ subject label, the object label and the action and look for a rule
+ that says that this action is either granted or denied.
+
+
+====================
+TYPES OF CREDENTIALS
+====================
+
+The Linux kernel supports the following types of credentials:
+
+ (1) Traditional UNIX credentials.
+
+ Real User ID
+ Real Group ID
+
+ The UID and GID are carried by most, if not all, Linux objects, even if in
+ some cases it has to be invented (FAT or CIFS files for example, which are
+ derived from Windows). These (mostly) define the objective context of
+ that object, with tasks being slightly different in some cases.
+
+ Effective, Saved and FS User ID
+ Effective, Saved and FS Group ID
+ Supplementary groups
+
+ These are additional credentials used by tasks only. Usually, an
+ EUID/EGID/GROUPS will be used as the subjective context, and real UID/GID
+ will be used as the objective. For tasks, it should be noted that this is
+ not always true.
+
+ (2) Capabilities.
+
+ Set of permitted capabilities
+ Set of inheritable capabilities
+ Set of effective capabilities
+ Capability bounding set
+
+ These are only carried by tasks. They indicate superior capabilities
+ granted piecemeal to a task that an ordinary task wouldn't otherwise have.
+ These are manipulated implicitly by changes to the traditional UNIX
+ credentials, but can also be manipulated directly by the capset() system
+ call.
+
+ The permitted capabilities are those caps that the process might grant
+ itself to its effective or permitted sets through capset(). This
+ inheritable set might also be so constrained.
+
+ The effective capabilities are the ones that a task is actually allowed to
+ make use of itself.
+
+ The inheritable capabilities are the ones that may get passed across
+ execve().
+
+ The bounding set limits the capabilities that may be inherited across
+ execve(), especially when a binary is executed that will execute as UID 0.
+
+ (3) Secure management flags (securebits).
+
+ These are only carried by tasks. These govern the way the above
+ credentials are manipulated and inherited over certain operations such as
+ execve(). They aren't used directly as objective or subjective
+ credentials.
+
+ (4) Keys and keyrings.
+
+ These are only carried by tasks. They carry and cache security tokens
+ that don't fit into the other standard UNIX credentials. They are for
+ making such things as network filesystem keys available to the file
+ accesses performed by processes, without the necessity of ordinary
+ programs having to know about security details involved.
+
+ Keyrings are a special type of key. They carry sets of other keys and can
+ be searched for the desired key. Each process may subscribe to a number
+ of keyrings:
+
+ Per-thread keying
+ Per-process keyring
+ Per-session keyring
+
+ When a process accesses a key, if not already present, it will normally be
+ cached on one of these keyrings for future accesses to find.
+
+ For more information on using keys, see Documentation/keys.txt.
+
+ (5) LSM
+
+ The Linux Security Module allows extra controls to be placed over the
+ operations that a task may do. Currently Linux supports two main
+ alternate LSM options: SELinux and Smack.
+
+ Both work by labelling the objects in a system and then applying sets of
+ rules (policies) that say what operations a task with one label may do to
+ an object with another label.
+
+ (6) AF_KEY
+
+ This is a socket-based approach to credential management for networking
+ stacks [RFC 2367]. It isn't discussed by this document as it doesn't
+ interact directly with task and file credentials; rather it keeps system
+ level credentials.
+
+
+When a file is opened, part of the opening task's subjective context is
+recorded in the file struct created. This allows operations using that file
+struct to use those credentials instead of the subjective context of the task
+that issued the operation. An example of this would be a file opened on a
+network filesystem where the credentials of the opened file should be presented
+to the server, regardless of who is actually doing a read or a write upon it.
+
+
+=============
+FILE MARKINGS
+=============
+
+Files on disk or obtained over the network may have annotations that form the
+objective security context of that file. Depending on the type of filesystem,
+this may include one or more of the following:
+
+ (*) UNIX UID, GID, mode;
+
+ (*) Windows user ID;
+
+ (*) Access control list;
+
+ (*) LSM security label;
+
+ (*) UNIX exec privilege escalation bits (SUID/SGID);
+
+ (*) File capabilities exec privilege escalation bits.
+
+These are compared to the task's subjective security context, and certain
+operations allowed or disallowed as a result. In the case of execve(), the
+privilege escalation bits come into play, and may allow the resulting process
+extra privileges, based on the annotations on the executable file.
+
+
+================
+TASK CREDENTIALS
+================
+
+In Linux, all of a task's credentials are held in (uid, gid) or through
+(groups, keys, LSM security) a refcounted structure of type 'struct cred'.
+Each task points to its credentials by a pointer called 'cred' in its
+task_struct.
+
+Once a set of credentials has been prepared and committed, it may not be
+changed, barring the following exceptions:
+
+ (1) its reference count may be changed;
+
+ (2) the reference count on the group_info struct it points to may be changed;
+
+ (3) the reference count on the security data it points to may be changed;
+
+ (4) the reference count on any keyrings it points to may be changed;
+
+ (5) any keyrings it points to may be revoked, expired or have their security
+ attributes changed; and
+
+ (6) the contents of any keyrings to which it points may be changed (the whole
+ point of keyrings being a shared set of credentials, modifiable by anyone
+ with appropriate access).
+
+To alter anything in the cred struct, the copy-and-replace principle must be
+adhered to. First take a copy, then alter the copy and then use RCU to change
+the task pointer to make it point to the new copy. There are wrappers to aid
+with this (see below).
+
+A task may only alter its _own_ credentials; it is no longer permitted for a
+task to alter another's credentials. This means the capset() system call is no
+longer permitted to take any PID other than the one of the current process.
+Also keyctl_instantiate() and keyctl_negate() functions no longer permit
+attachment to process-specific keyrings in the requesting process as the
+instantiating process may need to create them.
+
+
+IMMUTABLE CREDENTIALS
+---------------------
+
+Once a set of credentials has been made public (by calling commit_creds() for
+example), it must be considered immutable, barring two exceptions:
+
+ (1) The reference count may be altered.
+
+ (2) Whilst the keyring subscriptions of a set of credentials may not be
+ changed, the keyrings subscribed to may have their contents altered.
+
+To catch accidental credential alteration at compile time, struct task_struct
+has _const_ pointers to its credential sets, as does struct file. Furthermore,
+certain functions such as get_cred() and put_cred() operate on const pointers,
+thus rendering casts unnecessary, but require to temporarily ditch the const
+qualification to be able to alter the reference count.
+
+
+ACCESSING TASK CREDENTIALS
+--------------------------
+
+A task being able to alter only its own credentials permits the current process
+to read or replace its own credentials without the need for any form of locking
+- which simplifies things greatly. It can just call:
+
+ const struct cred *current_cred()
+
+to get a pointer to its credentials structure, and it doesn't have to release
+it afterwards.
+
+There are convenience wrappers for retrieving specific aspects of a task's
+credentials (the value is simply returned in each case):
+
+ uid_t current_uid(void) Current's real UID
+ gid_t current_gid(void) Current's real GID
+ uid_t current_euid(void) Current's effective UID
+ gid_t current_egid(void) Current's effective GID
+ uid_t current_fsuid(void) Current's file access UID
+ gid_t current_fsgid(void) Current's file access GID
+ kernel_cap_t current_cap(void) Current's effective capabilities
+ void *current_security(void) Current's LSM security pointer
+ struct user_struct *current_user(void) Current's user account
+
+There are also convenience wrappers for retrieving specific associated pairs of
+a task's credentials:
+
+ void current_uid_gid(uid_t *, gid_t *);
+ void current_euid_egid(uid_t *, gid_t *);
+ void current_fsuid_fsgid(uid_t *, gid_t *);
+
+which return these pairs of values through their arguments after retrieving
+them from the current task's credentials.
+
+
+In addition, there is a function for obtaining a reference on the current
+process's current set of credentials:
+
+ const struct cred *get_current_cred(void);
+
+and functions for getting references to one of the credentials that don't
+actually live in struct cred:
+
+ struct user_struct *get_current_user(void);
+ struct group_info *get_current_groups(void);
+
+which get references to the current process's user accounting structure and
+supplementary groups list respectively.
+
+Once a reference has been obtained, it must be released with put_cred(),
+free_uid() or put_group_info() as appropriate.
+
+
+ACCESSING ANOTHER TASK'S CREDENTIALS
+------------------------------------
+
+Whilst a task may access its own credentials without the need for locking, the
+same is not true of a task wanting to access another task's credentials. It
+must use the RCU read lock and rcu_dereference().
+
+The rcu_dereference() is wrapped by:
+
+ const struct cred *__task_cred(struct task_struct *task);
+
+This should be used inside the RCU read lock, as in the following example:
+
+ void foo(struct task_struct *t, struct foo_data *f)
+ {
+ const struct cred *tcred;
+ ...
+ rcu_read_lock();
+ tcred = __task_cred(t);
+ f->uid = tcred->uid;
+ f->gid = tcred->gid;
+ f->groups = get_group_info(tcred->groups);
+ rcu_read_unlock();
+ ...
+ }
+
+A function need not get RCU read lock to use __task_cred() if it is holding a
+spinlock at the time as this implicitly holds the RCU read lock.
+
+Should it be necessary to hold another task's credentials for a long period of
+time, and possibly to sleep whilst doing so, then the caller should get a
+reference on them using:
+
+ const struct cred *get_task_cred(struct task_struct *task);
+
+This does all the RCU magic inside of it. The caller must call put_cred() on
+the credentials so obtained when they're finished with.
+
+There are a couple of convenience functions to access bits of another task's
+credentials, hiding the RCU magic from the caller:
+
+ uid_t task_uid(task) Task's real UID
+ uid_t task_euid(task) Task's effective UID
+
+If the caller is holding a spinlock or the RCU read lock at the time anyway,
+then:
+
+ __task_cred(task)->uid
+ __task_cred(task)->euid
+
+should be used instead. Similarly, if multiple aspects of a task's credentials
+need to be accessed, RCU read lock or a spinlock should be used, __task_cred()
+called, the result stored in a temporary pointer and then the credential
+aspects called from that before dropping the lock. This prevents the
+potentially expensive RCU magic from being invoked multiple times.
+
+Should some other single aspect of another task's credentials need to be
+accessed, then this can be used:
+
+ task_cred_xxx(task, member)
+
+where 'member' is a non-pointer member of the cred struct. For instance:
+
+ uid_t task_cred_xxx(task, suid);
+
+will retrieve 'struct cred::suid' from the task, doing the appropriate RCU
+magic. This may not be used for pointer members as what they point to may
+disappear the moment the RCU read lock is dropped.
+
+
+ALTERING CREDENTIALS
+--------------------
+
+As previously mentioned, a task may only alter its own credentials, and may not
+alter those of another task. This means that it doesn't need to use any
+locking to alter its own credentials.
+
+To alter the current process's credentials, a function should first prepare a
+new set of credentials by calling:
+
+ struct cred *prepare_creds(void);
+
+this locks current->cred_replace_mutex and then allocates and constructs a
+duplicate of the current process's credentials, returning with the mutex still
+held if successful. It returns NULL if not successful (out of memory).
+
+The mutex prevents ptrace() from altering the ptrace state of a process whilst
+security checks on credentials construction and changing is taking place as
+the ptrace state may alter the outcome, particularly in the case of execve().
+
+The new credentials set should be altered appropriately, and any security
+checks and hooks done. Both the current and the proposed sets of credentials
+are available for this purpose as current_cred() will return the current set
+still at this point.
+
+
+When the credential set is ready, it should be committed to the current process
+by calling:
+
+ int commit_creds(struct cred *new);
+
+This will alter various aspects of the credentials and the process, giving the
+LSM a chance to do likewise, then it will use rcu_assign_pointer() to actually
+commit the new credentials to current->cred, it will release
+current->cred_replace_mutex to allow ptrace() to take place, and it will notify
+the scheduler and others of the changes.
+
+This function is guaranteed to return 0, so that it can be tail-called at the
+end of such functions as sys_setresuid().
+
+Note that this function consumes the caller's reference to the new credentials.
+The caller should _not_ call put_cred() on the new credentials afterwards.
+
+Furthermore, once this function has been called on a new set of credentials,
+those credentials may _not_ be changed further.
+
+
+Should the security checks fail or some other error occur after prepare_creds()
+has been called, then the following function should be invoked:
+
+ void abort_creds(struct cred *new);
+
+This releases the lock on current->cred_replace_mutex that prepare_creds() got
+and then releases the new credentials.
+
+
+A typical credentials alteration function would look something like this:
+
+ int alter_suid(uid_t suid)
+ {
+ struct cred *new;
+ int ret;
+
+ new = prepare_creds();
+ if (!new)
+ return -ENOMEM;
+
+ new->suid = suid;
+ ret = security_alter_suid(new);
+ if (ret < 0) {
+ abort_creds(new);
+ return ret;
+ }
+
+ return commit_creds(new);
+ }
+
+
+MANAGING CREDENTIALS
+--------------------
+
+There are some functions to help manage credentials:
+
+ (*) void put_cred(const struct cred *cred);
+
+ This releases a reference to the given set of credentials. If the
+ reference count reaches zero, the credentials will be scheduled for
+ destruction by the RCU system.
+
+ (*) const struct cred *get_cred(const struct cred *cred);
+
+ This gets a reference on a live set of credentials, returning a pointer to
+ that set of credentials.
+
+ (*) struct cred *get_new_cred(struct cred *cred);
+
+ This gets a reference on a set of credentials that is under construction
+ and is thus still mutable, returning a pointer to that set of credentials.
+
+
+=====================
+OPEN FILE CREDENTIALS
+=====================
+
+When a new file is opened, a reference is obtained on the opening task's
+credentials and this is attached to the file struct as 'f_cred' in place of
+'f_uid' and 'f_gid'. Code that used to access file->f_uid and file->f_gid
+should now access file->f_cred->fsuid and file->f_cred->fsgid.
+
+It is safe to access f_cred without the use of RCU or locking because the
+pointer will not change over the lifetime of the file struct, and nor will the
+contents of the cred struct pointed to, barring the exceptions listed above
+(see the Task Credentials section).
+
+
+=======================================
+OVERRIDING THE VFS'S USE OF CREDENTIALS
+=======================================
+
+Under some circumstances it is desirable to override the credentials used by
+the VFS, and that can be done by calling into such as vfs_mkdir() with a
+different set of credentials. This is done in the following places:
+
+ (*) sys_faccessat().
+
+ (*) do_coredump().
+
+ (*) nfs4recover.c.
instruction doesn't work correctly and not to
use it.
+ no_file_caps Tells the kernel not to honor file capabilities. The
+ only way then for a file to be executed with privilege
+ is to be setuid root or executed by root.
+
nohalt [IA-64] Tells the kernel not to use the power saving
function PAL_HALT_LIGHT when idle. This increases
power-consumption. On the positive side, it reduces
# #Launch gmplayer (or your favourite movie player)
# echo <movie_player_pid> > multimedia/tasks
+
+8. Implementation note: user namespaces
+
+User namespaces are intended to be hierarchical. But they are currently
+only partially implemented. Each of those has ramifications for CFS.
+
+First, since user namespaces are hierarchical, the /sys/kernel/uids
+presentation is inadequate. Eventually we will likely want to use sysfs
+tagging to provide private views of /sys/kernel/uids within each user
+namespace.
+
+Second, the hierarchical nature is intended to support completely
+unprivileged use of user namespaces. So if using user groups, then
+we want the users in a user namespace to be children of the user
+who created it.
+
+That is currently unimplemented. So instead, every user in a new
+user namespace will receive 1024 shares just like any user in the
+initial user namespace. Note that at the moment creation of a new
+user namespace requires each of CAP_SYS_ADMIN, CAP_SETUID, and
+CAP_SETGID.

-
-This file describes the configuration and behavior of KGDB for the SH
-kernel. Based on a description from Henry Bell <henry.bell@st.com>, it
-has been modified to account for quirks in the current implementation.
-
-Version
-=======
-
-This version of KGDB was written for 2.4.xx kernels for the SH architecture.
-Further documentation is available from the linux-sh project website.
-
-
-Debugging Setup: Host
-======================
-
-The two machines will be connected together via a serial line - this
-should be a null modem cable i.e. with a twist.
-
-On your DEVELOPMENT machine, go to your kernel source directory and
-build the kernel, enabling KGDB support in the "kernel hacking" section.
-This includes the KGDB code, and also makes the kernel be compiled with
-the "-g" option set -- necessary for debugging.
-
-To install this new kernel, use the following installation procedure.
-
-Decide on which tty port you want the machines to communicate, then
-cable them up back-to-back using the null modem. On the DEVELOPMENT
-machine, you may wish to create an initialization file called .gdbinit
-(in the kernel source directory or in your home directory) to execute
-commonly-used commands at startup.
-
-A minimal .gdbinit might look like this:
-
- file vmlinux
- set remotebaud 115200
- target remote /dev/ttyS0
-
-Change the "target" definition so that it specifies the tty port that
-you intend to use. Change the "remotebaud" definition to match the
-data rate that you are going to use for the com line (115200 is the
-default).
-
-Debugging Setup: Target
-========================
-
-By default, the KGDB stub will communicate with the host GDB using
-ttySC1 at 115200 baud, 8 databits, no parity; these defaults can be
-changed in the kernel configuration. As the kernel starts up, KGDB will
-initialize so that breakpoints, kernel segfaults, and so forth will
-generally enter the debugger.
-
-This behavior can be modified by including the "kgdb" option in the
-kernel command line; this option has the general form:
-
- kgdb=<ttyspec>,<action>
-
-The <ttyspec> indicates the port to use, and can optionally specify
-baud, parity and databits -- e.g. "ttySC0,9600N8" or "ttySC1,19200".
-
-The <action> can be "halt" or "disabled". The "halt" action enters the
-debugger via a breakpoint as soon as kgdb is initialized; the "disabled"
-action causes kgdb to ignore kernel segfaults and such until explicitly
-entered by a breakpoint in the code or by external action (sysrq or NMI).
-
-(Both <ttyspec> and <action> can appear alone, w/o the separating comma.)
-
-For example, if you wish to debug early in kernel startup code, you
-might specify the halt option:
-
- kgdb=halt
-
-Boot the TARGET machine, which will appear to hang.
-
-On your DEVELOPMENT machine, cd to the source directory and run the gdb
-program. (This is likely to be a cross GDB which runs on your host but
-is built for an SH target.) If everything is working correctly you
-should see gdb print out a few lines indicating that a breakpoint has
-been taken. It will actually show a line of code in the target kernel
-inside the gdbstub activation code.
-
-NOTE: BE SURE TO TERMINATE OR SUSPEND any other host application which
-may be using the same serial port (for example, a terminal emulator you
-have been using to connect to the target boot code.) Otherwise, data
-from the target may not all get to GDB!
-
-You can now use whatever gdb commands you like to set breakpoints.
-Enter "continue" to start your target machine executing again. At this
-point the target system will run at full speed until it encounters
-your breakpoint or gets a segment violation in the kernel, or whatever.
-
-Serial Ports: KGDB, Console
-============================
-
-This version of KGDB may not gracefully handle conflict with other
-drivers in the kernel using the same port. If KGDB is configured on the
-same port (and with the same parameters) as the kernel console, or if
-CONFIG_SH_KGDB_CONSOLE is configured, things should be fine (though in
-some cases console messages may appear twice through GDB). But if the
-KGDB port is not the kernel console and used by another serial driver
-which assumes different serial parameters (e.g. baud rate) KGDB may not
-recover.
-
-Also, when KGDB is entered via sysrq-g (requires CONFIG_KGDB_SYSRQ) and
-the kgdb port uses the same port as the console, detaching GDB will not
-restore the console to working order without the port being re-opened.
-
-Another serious consequence of this is that GDB currently CANNOT break
-into KGDB externally (e.g. via ^C or <BREAK>); unless a breakpoint or
-error is encountered, the only way to enter KGDB after the initial halt
-(see above) is via NMI (CONFIG_KGDB_NMI) or sysrq-g (CONFIG_KGDB_SYSRQ).
-
-Code is included for the basic Hitachi Solution Engine boards to allow
-the use of ttyS0 for KGDB if desired; this is less robust, but may be
-useful in some cases. (This cannot be selected using the config file,
-but only through the kernel command line, e.g. "kgdb=ttyS0", though the
-configured defaults for baud rate etc. still apply if not overridden.)
-
-If gdbstub Does Not Work
-========================
-
-If it doesn't work, you will have to troubleshoot it. Do the easy
-things first like double checking your cabling and data rates. You
-might try some non-kernel based programs to see if the back-to-back
-connection works properly. Just something simple like cat /etc/hosts
-/dev/ttyS0 on one machine and cat /dev/ttyS0 on the other will tell you
-if you can send data from one machine to the other. There is no point
-in tearing out your hair in the kernel if the line doesn't work.
-
-If you need to debug the GDB/KGDB communication itself, the gdb commands
-"set debug remote 1" and "set debug serial 1" may be useful, but be
-warned: they produce a lot of output.
-
-Threads
-=======
-
-Each process in a target machine is seen as a gdb thread. gdb thread related
-commands (info threads, thread n) can be used. CONFIG_KGDB_THREAD must
-be defined for this to work.
-
-In this version, kgdb reports PID_MAX (32768) as the process ID for the
-idle process (pid 0), since GDB does not accept 0 as an ID.
-
-Detaching (exiting KGDB)
-=========================
-
-There are two ways to resume full-speed target execution: "continue" and
-"detach". With "continue", GDB inserts any specified breakpoints in the
-target code and resumes execution; the target is still in "gdb mode".
-If a breakpoint or other debug event (e.g. NMI) happens, the target
-halts and communicates with GDB again, which is waiting for it.
-
-With "detach", GDB does *not* insert any breakpoints; target execution
-is resumed and GDB stops communicating (does not wait for the target).
-In this case, the target is no longer in "gdb mode" -- for example,
-console messages no longer get sent separately to the KGDB port, or
-encapsulated for GDB. If a debug event (e.g. NMI) occurs, the target
-will re-enter "gdb mode" and will display this fact on the console; you
-must give a new "target remote" command to gdb.
-
-NOTE: TO AVOID LOSSING CONSOLE MESSAGES IN CASE THE KERNEL CONSOLE AND
-KGDB USING THE SAME PORT, THE TARGET WAITS FOR ANY INPUT CHARACTER ON
-THE KGDB PORT AFTER A DETACH COMMAND. For example, after the detach you
-could start a terminal emulator on the same host port and enter a <cr>;
-however, this program must then be terminated or suspended in order to
-use GBD again if KGDB is re-entered.

Each codec may have a model table for different configurations.
If your machine isn't listed there, the default (usually minimal)
configuration is set up. You can pass "model=<name>" option to
specify a certain model in such a case. There are different
- models depending on the codec chip.

+MORE NOTES ON HD-AUDIO DRIVER
+=============================
+ Takashi Iwai <tiwai@suse.de>
+
+
+GENERAL
+-------
+
+HD-audio is the new standard on-board audio component on modern PCs
+after AC97. Although Linux has been supporting HD-audio since long
+time ago, there are often problems with new machines. A part of the
+problem is broken BIOS, and the rest is the driver implementation.
+This document explains the brief trouble-shooting and debugging
+methods for the HD-audio hardware.
+
+The HD-audio component consists of two parts: the controller chip and
+the codec chips on the HD-audio bus. Linux provides a single driver
+for all controllers, snd-hda-intel. Although the driver name contains
+a word of a well-known harware vendor, it's not specific to it but for
+all controller chips by other companies. Since the HD-audio
+controllers are supposed to be compatible, the single snd-hda-driver
+should work in most cases. But, not surprisingly, there are known
+bugs and issues specific to each controller type. The snd-hda-intel
+driver has a bunch of workarounds for these as described below.
+
+A controller may have multiple codecs. Usually you have one audio
+codec and optionally one modem codec. In theory, there might be
+multiple audio codecs, e.g. for analog and digital outputs, and the
+driver might not work properly because of conflict of mixer elements.
+This should be fixed in future if such hardware really exists.
+
+The snd-hda-intel driver has several different codec parsers depending
+on the codec. It has a generic parser as a fallback, but this
+functionality is fairly limited until now. Instead of the generic
+parser, usually the codec-specific parser (coded in patch_*.c) is used
+for the codec-specific implementations. The details about the
+codec-specific problems are explained in the later sections.
+
+If you are interested in the deep debugging of HD-audio, read the
+HD-audio specification at first. The specification is found on
+Intel's web page, for example:
+
+- http://www.intel.com/standards/hdaudio/
+
+
+HD-AUDIO CONTROLLER
+-------------------
+
+DMA-Position Problem
+~~~~~~~~~~~~~~~~~~~~
+The most common problem of the controller is the inaccurate DMA
+pointer reporting. The DMA pointer for playback and capture can be
+read in two ways, either via a LPIB register or via a position-buffer
+map. As default the driver tries to read from the io-mapped
+position-buffer, and falls back to LPIB if the position-buffer appears
+dead. However, this detection isn't perfect on some devices. In such
+a case, you can change the default method via `position_fix` option.
+
+`position_fix=1` means to use LPIB method explicitly.
+`position_fix=2` means to use the position-buffer. 0 is the default
+value, the automatic check and fallback to LPIB as described in the
+above. If you get a problem of repeated sounds, this option might
+help.
+
+In addition to that, every controller is known to be broken regarding
+the wake-up timing. It wakes up a few samples before actually
+processing the data on the buffer. This caused a lot of problems, for
+example, with ALSA dmix or JACK. Since 2.6.27 kernel, the driver puts
+an artificial delay to the wake up timing. This delay is controlled
+via `bdl_pos_adj` option.
+
+When `bdl_pos_adj` is a negative value (as default), it's assigned to
+an appropriate value depending on the controller chip. For Intel
+chips, it'd be 1 while it'd be 32 for others. Usually this works.
+Only in case it doesn't work and you get warning messages, you should
+change this parameter to other values.
+
+
+Codec-Probing Problem
+~~~~~~~~~~~~~~~~~~~~~
+A less often but a more severe problem is the codec probing. When
+BIOS reports the available codec slots wrongly, the driver gets
+confused and tries to access the non-existing codec slot. This often
+results in the total screw-up, and destructs the further communication
+with the codec chips. The symptom appears usually as error messages
+like:
+------------------------------------------------------------------------
+ hda_intel: azx_get_response timeout, switching to polling mode:
+ last cmd=0x12345678
+ hda_intel: azx_get_response timeout, switching to single_cmd mode:
+ last cmd=0x12345678
+------------------------------------------------------------------------
+
+The first line is a warning, and this is usually relatively harmless.
+It means that the codec response isn't notified via an IRQ. The
+driver uses explicit polling method to read the response. It gives
+very slight CPU overhead, but you'd unlikely notice it.
+
+The second line is, however, a fatal error. If this happens, usually
+it means that something is really wrong. Most likely you are
+accessing a non-existing codec slot.
+
+Thus, if the second error message appears, try to narrow the probed
+codec slots via `probe_mask` option. It's a bitmask, and each bit
+corresponds to the codec slot. For example, to probe only the first
+slot, pass `probe_mask=1`. For the first and the third slots, pass
+`probe_mask=5` (where 5 = 1 | 4), and so on.
+
+Since 2.6.29 kernel, the driver has a more robust probing method, so
+this error might happen rarely, though.
+
+
+Interrupt Handling
+~~~~~~~~~~~~~~~~~~
+In rare but some cases, the interrupt isn't properly handled as
+default. You would notice this by the DMA transfer error reported by
+ALSA PCM core, for example. Using MSI might help in such a case.
+Pass `enable_msi=1` option for enabling MSI.
+
+
+HD-AUDIO CODEC
+--------------
+
+Model Option
+~~~~~~~~~~~~
+The most common problem regarding the HD-audio driver is the
+unsupported codec features or the mismatched device configuration.
+Most of codec-specific code has several preset models, either to
+override the BIOS setup or to provide more comprehensive features.
+
+The driver checks PCI SSID and looks through the static configuration
+table until any matching entry is found. If you have a new machine,
+you may see a message like below:
+------------------------------------------------------------------------
+ hda_codec: Unknown model for ALC880, trying auto-probe from BIOS...
+------------------------------------------------------------------------
+Even if you see such a message, DON'T PANIC. Take a deep breath and
+keep your towel. First of all, it's an informational message, no
+warning, no error. This means that the PCI SSID of your device isn't
+listed in the known preset model (white-)list. But, this doesn't mean
+that the driver is broken. Many codec-drivers provide the automatic
+configuration mechanism based on the BIOS setup.
+
+The HD-audio codec has usually "pin" widgets, and BIOS sets the default
+configuration of each pin, which indicates the location, the
+connection type, the jack color, etc. The HD-audio driver can guess
+the right connection judging from these default configuration values.
+However -- some codec-support codes, such as patch_analog.c, don't
+support the automatic probing (yet as of 2.6.28). And, BIOS is often,
+yes, pretty often broken. It sets up wrong values and screws up the
+driver.
+
+The preset model is provided basically to overcome such a situation.
+When the matching preset model is found in the white-list, the driver
+assumes the static configuration of that preset and builds the mixer
+elements and PCM streams based on the static information. Thus, if
+you have a newer machine with a slightly different PCI SSID from the
+existing one, you may have a good chance to re-use the same model.
+You can pass the `model` option to specify the preset model instead of
+PCI SSID look-up.
+
+What `model` option values are available depends on the codec chip.
+Check your codec chip from the codec proc file (see "Codec Proc-File"
+section below). It will show the vendor/product name of your codec
+chip. Then, see Documentation/sound/alsa/HD-Audio-Modelstxt file,
+the section of HD-audio driver. You can find a list of codecs
+and `model` options belonging to each codec. For example, for Realtek
+ALC262 codec chip, pass `model=ultra` for devices that are compatible
+with Samsung Q1 Ultra.
+
+Thus, the first thing you can do for any brand-new, unsupported and
+non-working HD-audio hardware is to check HD-audio codec and several
+different `model` option values. If you have a luck, some of them
+might suit with your device well.
+
+Some codecs such as ALC880 have a special model option `model=test`.
+This configures the driver to provide as many mixer controls as
+possible for every single pin feature except for the unsolicited
+events (and maybe some other specials). Adjust each mixer element and
+try the I/O in the way of trial-and-error until figuring out the whole
+I/O pin mappings.
+
+Note that `model=generic` has a special meaning. It means to use the
+generic parser regardless of the codec. Usually the codec-specific
+parser is much better than the generic parser (as now). Thus this
+option is more about the debugging purpose.
+
+
+Speaker and Headphone Output
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+One of the most frequent (and obvious) bugs with HD-audio is the
+silent output from either or both of a built-in speaker and a
+headphone jack. In general, you should try a headphone output at
+first. A speaker output often requires more additional controls like
+the external amplifier bits. Thus a headphone output has a slightly
+better chance.
+
+Before making a bug report, double-check whether the mixer is set up
+correctly. The recent version of snd-hda-intel driver provides mostly
+"Master" volume control as well as "Front" volume (where Front
+indicates the front-channels). In addition, there can be individual
+"Headphone" and "Speaker" controls.
+
+Ditto for the speaker output. There can be "External Amplifier"
+switch on some codecs. Turn on this if present.
+
+Another related problem is the automatic mute of speaker output by
+headphone plugging. This feature is implemented in most cases, but
+not on every preset model or codec-support code.
+
+In anyway, try a different model option if you have such a problem.
+Some other models may match better and give you more matching
+functionality. If none of the available models works, send a bug
+report. See the bug report section for details.
+
+If you are masochistic enough to debug the driver problem, note the
+following:
+
+- The speaker (and the headphone, too) output often requires the
+ external amplifier. This can be set usually via EAPD verb or a
+ certain GPIO. If the codec pin supports EAPD, you have a better
+ chance via SET_EAPD_BTL verb (0x70c). On others, GPIO pin (mostly
+ it's either GPIO0 or GPIO1) may turn on/off EAPD.
+- Some Realtek codecs require special vendor-specific coefficients to
+ turn on the amplifier. See patch_realtek.c.
+- IDT codecs may have extra power-enable/disable controls on each
+ analog pin. See patch_sigmatel.c.
+- Very rare but some devices don't accept the pin-detection verb until
+ triggered. Issuing GET_PIN_SENSE verb (0xf09) may result in the
+ codec-communication stall. Some examples are found in
+ patch_realtek.c.
+
+
+Capture Problems
+~~~~~~~~~~~~~~~~
+The capture problems are often because of missing setups of mixers.
+Thus, before submitting a bug report, make sure that you set up the
+mixer correctly. For example, both "Capture Volume" and "Capture
+Switch" have to be set properly in addition to the right "Capture
+Source" or "Input Source" selection. Some devices have "Mic Boost"
+volume or switch.
+
+When the PCM device is opened via "default" PCM (without pulse-audio
+plugin), you'll likely have "Digital Capture Volume" control as well.
+This is provided for the extra gain/attenuation of the signal in
+software, especially for the inputs without the hardware volume
+control such as digital microphones. Unless really needed, this
+should be set to exactly 50%, corresponding to 0dB -- neither extra
+gain nor attenuation. When you use "hw" PCM, i.e., a raw access PCM,
+this control will have no influence, though.
+
+It's known that some codecs / devices have fairly bad analog circuits,
+and the recorded sound contains a certain DC-offset. This is no bug
+of the driver.
+
+Most of modern laptops have no analog CD-input connection. Thus, the
+recording from CD input won't work in many cases although the driver
+provides it as the capture source. Use CDDA instead.
+
+The automatic switching of the built-in and external mic per plugging
+is implemented on some codec models but not on every model. Partly
+because of my laziness but mostly lack of testers. Feel free to
+submit the improvement patch to the author.
+
+
+Direct Debugging
+~~~~~~~~~~~~~~~~
+If no model option gives you a better result, and you are a tough guy
+to fight against evil, try debugging via hitting the raw HD-audio
+codec verbs to the device. Some tools are available: hda-emu and
+hda-analyzer. The detailed description is found in the sections
+below. You'd need to enable hwdep for using these tools. See "Kernel
+Configuration" section.
+
+
+OTHER ISSUES
+------------
+
+Kernel Configuration
+~~~~~~~~~~~~~~~~~~~~
+In general, I recommend you to enable the sound debug option,
+`CONFIG_SND_DEBUG=y`, no matter whether you are debugging or not.
+This enables snd_printd() macro and others, and you'll get additional
+kernel messages at probing.
+
+In addition, you can enable `CONFIG_SND_DEBUG_VERBOSE=y`. But this
+will give you far more messages. Thus turn this on only when you are
+sure to want it.
+
+Don't forget to turn on the appropriate `CONFIG_SND_HDA_CODEC_*`
+options. Note that each of them corresponds to the codec chip, not
+the controller chip. Thus, even if lspci shows the Nvidia controller,
+you may need to choose the option for other vendors. If you are
+unsure, just select all yes.
+
+`CONFIG_SND_HDA_HWDEP` is a useful option for debugging the driver.
+When this is enabled, the driver creates hardware-dependent devices
+(one per each codec), and you have a raw access to the device via
+these device files. For example, `hwC0D2` will be created for the
+codec slot #2 of the first card (#0). For debug-tools such as
+hda-verb and hda-analyzer, the hwdep device has to be enabled.
+Thus, it'd be better to turn this on always.
+
+`CONFIG_SND_HDA_RECONFIG` is a new option, and this depends on the
+hwdep option above. When enabled, you'll have some sysfs files under
+the corresponding hwdep directory. See "HD-audio reconfiguration"
+section below.
+
+`CONFIG_SND_HDA_POWER_SAVE` option enables the power-saving feature.
+See "Power-saving" section below.
+
+
+Codec Proc-File
+~~~~~~~~~~~~~~~
+The codec proc-file is a treasure-chest for debugging HD-audio.
+It shows most of useful information of each codec widget.
+
+The proc file is located in /proc/asound/card*/codec#*, one file per
+each codec slot. You can know the codec vendor, product id and
+names, the type of each widget, capabilities and so on.
+This file, however, doesn't show the jack sensing state, so far. This
+is because the jack-sensing might be depending on the trigger state.
+
+This file will be picked up by the debug tools, and also it can be fed
+to the emulator as the primary codec information. See the debug tools
+section below.
+
+This proc file can be also used to check whether the generic parser is
+used. When the generic parser is used, the vendor/product ID name
+will appear as "Realtek ID 0262", instead of "Realtek ALC262".
+
+
+HD-Audio Reconfiguration
+~~~~~~~~~~~~~~~~~~~~~~~~
+This is an experimental feature to allow you re-configure the HD-audio
+codec dynamically without reloading the driver. The following sysfs
+files are available under each codec-hwdep device directory (e.g.
+/sys/class/sound/hwC0D0):
+
+vendor_id::
+ Shows the 32bit codec vendor-id hex number. You can change the
+ vendor-id value by writing to this file.
+subsystem_id::
+ Shows the 32bit codec subsystem-id hex number. You can change the
+ subsystem-id value by writing to this file.
+revision_id::
+ Shows the 32bit codec revision-id hex number. You can change the
+ revision-id value by writing to this file.
+afg::
+ Shows the AFG ID. This is read-only.
+mfg::
+ Shows the MFG ID. This is read-only.
+name::
+ Shows the codec name string. Can be changed by writing to this
+ file.
+modelname::
+ Shows the currently set `model` option. Can be changed by writing
+ to this file.
+init_verbs::
+ The extra verbs to execute at initialization. You can add a verb by
+ writing to this file. Pass tree numbers, nid, verb and parameter.
+hints::
+ Shows hint strings for codec parsers for any use. Right now it's
+ not used.
+reconfig::
+ Triggers the codec re-configuration. When any value is written to
+ this file, the driver re-initialize and parses the codec tree
+ again. All the changes done by the sysfs entries above are taken
+ into account.
+clear::
+ Resets the codec, removes the mixer elements and PCM stuff of the
+ specified codec, and clear all init verbs and hints.
+
+
+Power-Saving
+~~~~~~~~~~~~
+The power-saving is a kind of auto-suspend of the device. When the
+device is inactive for a certain time, the device is automatically
+turned off to save the power. The time to go down is specified via
+`power_save` module option, and this option can be changed dynamically
+via sysfs.
+
+The power-saving won't work when the analog loopback is enabled on
+some codecs. Make sure that you mute all unneeded signal routes when
+you want the power-saving.
+
+The power-saving feature might cause audible click noises at each
+power-down/up depending on the device. Some of them might be
+solvable, but some are hard, I'm afraid. Some distros such as
+openSUSE enables the power-saving feature automatically when the power
+cable is unplugged. Thus, if you hear noises, suspect first the
+power-saving. See /sys/module/snd_hda_intel/parameters/power_save to
+check the current value. If it's non-zero, the feature is turned on.
+
+
+Development Tree
+~~~~~~~~~~~~~~~~
+The latest development codes for HD-audio are found on sound git tree:
+
+- git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
+
+The master branch or for-next branches can be used as the main
+development branches in general while the HD-audio specific patches
+are committed in topic/hda branch.
+
+If you are using the latest Linus tree, it'd be better to pull the
+above GIT tree onto it. If you are using the older kernels, an easy
+way to try the latest ALSA code is to build from the snapshot
+tarball. There are daily tarballs and the latest snapshot tarball.
+All can be built just like normal alsa-driver release packages, that
+is, installed via the usual spells: configure, make and make
+install(-modules). See INSTALL in the package. The snapshot tarballs
+are found at:
+
+- ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/
+
+
+Sending a Bug Report
+~~~~~~~~~~~~~~~~~~~~
+If any model or module options don't work for your device, it's time
+to send a bug report to the developers. Give the following in your
+bug report:
+
+- Hardware vendor, product and model names
+- Kernel version (and ALSA-driver version if you built externally)
+- `alsa-info.sh` output; run with `--no-upload` option. See the
+ section below about alsa-info
+
+If it's a regression, at best, send alsa-info outputs of both working
+and non-working kernels. This is really helpful because we can
+compare the codec registers directly.
+
+Send a bug report either the followings:
+
+kernel-bugzilla::
+ http://bugme.linux-foundation.org/
+alsa-devel ML::
+ alsa-devel@alsa-project.org
+
+
+DEBUG TOOLS
+-----------
+
+This section describes some tools available for debugging HD-audio
+problems.
+
+alsa-info
+~~~~~~~~~
+The script `alsa-info.sh` is a very useful tool to gather the audio
+device information. You can fetch the latest version from:
+
+- http://www.alsa-project.org/alsa-info.sh
+
+Run this script as root, and it will gather the important information
+such as the module lists, module parameters, proc file contents
+including the codec proc files, mixer outputs and the control
+elements. As default, it will store the information onto a web server
+on alsa-project.org. But, if you send a bug report, it'd be better to
+run with `--no-upload` option, and attach the generated file.
+
+There are some other useful options. See `--help` option output for
+details.
+
+
+hda-verb
+~~~~~~~~
+hda-verb is a tiny program that allows you to access the HD-audio
+codec directly. You can execute a raw HD-audio codec verb with this.
+This program accesses the hwdep device, thus you need to enable the
+kernel config `CONFIG_SND_HDA_HWDEP=y` beforehand.
+
+The hda-verb program takes four arguments: the hwdep device file, the
+widget NID, the verb and the parameter. When you access to the codec
+on the slot 2 of the card 0, pass /dev/snd/hwC0D2 to the first
+argument, typically. (However, the real path name depends on the
+system.)
+
+The second parameter is the widget number-id to access. The third
+parameter can be either a hex/digit number or a string corresponding
+to a verb. Similarly, the last parameter is the value to write, or
+can be a string for the parameter type.
+
+------------------------------------------------------------------------
+ % hda-verb /dev/snd/hwC0D0 0x12 0x701 2
+ nid = 0x12, verb = 0x701, param = 0x2
+ value = 0x0
+
+ % hda-verb /dev/snd/hwC0D0 0x0 PARAMETERS VENDOR_ID
+ nid = 0x0, verb = 0xf00, param = 0x0
+ value = 0x10ec0262
+
+ % hda-verb /dev/snd/hwC0D0 2 set_a 0xb080
+ nid = 0x2, verb = 0x300, param = 0xb080
+ value = 0x0
+------------------------------------------------------------------------
+
+Although you can issue any verbs with this program, the driver state
+won't be always updated. For example, the volume values are usually
+cached in the driver, and thus changing the widget amp value directly
+via hda-verb won't change the mixer value.
+
+The hda-verb program is found in the ftp directory:
+

+hda-analyzer
+~~~~~~~~~~~~
+hda-analyzer provides a graphical interface to access the raw HD-audio
+control, based on pyGTK2 binding. It's a more powerful version of
+hda-verb. The program gives you an easy-to-use GUI stuff for showing
+the widget information and adjusting the amp values, as well as the
+proc-compatible output.
+
+The hda-analyzer is a part of alsa.git repository in
+alsa-project.org:
+
+- http://git.alsa-project.org/?p=alsa.git;a=tree;f=hda-analyzer
+
+
+Codecgraph
+~~~~~~~~~~
+Codecgraph is a utility program to generate a graph and visualizes the
+codec-node connection of a codec chip. It's especially useful when
+you analyze or debug a codec without a proper datasheet. The program
+parses the given codec proc file and converts to SVG via graphiz
+program.
+
+The tarball and GIT trees are found in the web page at:
+
+- http://helllabs.org/codecgraph/
+
+
+hda-emu
+~~~~~~~
+hda-emu is an HD-audio emulator. The main purpose of this program is
+to debug an HD-audio codec without the real hardware. Thus, it
+doesn't emulate the behavior with the real audio I/O, but it just
+dumps the codec register changes and the ALSA-driver internal changes
+at probing and operating the HD-audio driver.
+
+The program requires a codec proc-file to simulate. Get a proc file
+for the target codec beforehand, or pick up an example codec from the
+codec proc collections in the tarball. Then, run the program with the
+proc file, and the hda-emu program will start parsing the codec file
+and simulates the HD-audio driver:
+
+------------------------------------------------------------------------
+ % hda-emu codecs/stac9200-dell-d820-laptop
+ # Parsing..
+ hda_codec: Unknown model for STAC9200, using BIOS defaults
+ hda_codec: pin nid 08 bios pin config 40c003fa
+ ....
+------------------------------------------------------------------------
+
+The program gives you only a very dumb command-line interface. You
+can get a proc-file dump at the current state, get a list of control
+(mixer) elements, set/get the control element value, simulate the PCM
+operation, the jack plugging simulation, etc.
+
+The package is found in:
+
+- ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/
+
+A git repository is available:
+
+- git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/hda-emu.git
+
+See README file in the tarball for more details about hda-emu
+program.

widget node.

+ Available for HDMI or DisplayPort interfaces.
+ Shows ELD(EDID Like Data) info retrieved from the attached HDMI sink,
+ and describes its audio capabilities and configurations.
+
+ Some ELD fields may be modified by doing `echo name hex_value > eld#*`.
+ Only do this if you are sure the HDMI sink provided value is wrong.
+ And if that makes your HDMI audio work, please report to us so that we
+ can fix it in future kernel releases.

-
- The Dreamcast's System ASIC (a.k.a. Holly) is responsible for receiving
- hardware events from system peripherals and triggering an SH7750 IRQ.
- Hardware events can trigger IRQs 13, 11, or 9 depending on which bits are
- set in the Event Mask Registers (EMRs). When a hardware event is
- triggered, it's corresponding bit in the Event Status Registers (ESRs)
- is set, and that bit should be rewritten to the ESR to acknowledge that
- event.
-
- There are three 32-bit ESRs located at 0xa05f8900 - 0xa05f6908. Event
- types can be found in include/asm-sh/dreamcast/sysasic.h. There are three
- groups of EMRs that parallel the ESRs. Each EMR group corresponds to an
- IRQ, so 0xa05f6910 - 0xa05f6918 triggers IRQ 13, 0xa05f6920 - 0xa05f6928
- triggers IRQ 11, and 0xa05f6930 - 0xa05f6938 triggers IRQ 9.
-
- In the kernel, these events are mapped to virtual IRQs so that drivers can
- respond to them as they would a normal interrupt. In order to keep this
- mapping simple, the events are mapped as:
-
- 6900/6910 - Events 0-31, IRQ 13
- 6904/6924 - Events 32-63, IRQ 11
- 6908/6938 - Events 64-95, IRQ 9

- * This implements a small wrapper set to make code using the old ISA DMA API
- * work with the SH DMA API. Since most of the work in the new API happens
- * at ops->xfer() time, we simply use the various set_dma_xxx() routines to
- * fill in per-channel info, and then hand hand this off to ops->xfer() at
- * enable_dma() time.
- *
- * For channels that are doing on-demand data transfer via cascading, the
- * channel itself will still need to be configured through the new API. As
- * such, this code is meant for only the simplest of tasks (and shouldn't be
- * used in any new drivers at all).
- *
- * NOTE: ops->xfer() is the preferred way of doing things. However, there
- * are some users of the ISA DMA API that exist in common code that we
- * don't necessarily want to go out of our way to break, so we still
- * allow for some compatibility at that level. Any new code is strongly
- * advised to run far away from the ISA DMA API and use the SH DMA API
- * directly.

- * License. See linux/COPYING for more information.
- *
- * Contains extracts from code by Glenn Engel, Jim Kingdon,
- * David Grothe <dave@gcom.com>, Tigran Aivazian <tigran@sco.com>,
- * Amit S. Kale <akale@veritas.com>, William Gatliff <bgat@open-widgets.com>,

- *
- * This version by Henry Bell <henry.bell@st.com>
- * Minor modifications by Jeremy Siegel <jsiegel@mvista.com>
- *
- * Contains low-level support for remote debug using GDB.
- *
- * To enable debugger support, two things need to happen. A call to
- * set_debug_traps() is necessary in order to allow any breakpoints
- * or error conditions to be properly intercepted and reported to gdb.
- * A breakpoint also needs to be generated to begin communication. This
- * is most easily accomplished by a call to breakpoint() which does
- * a trapa if the initialisation phase has been successfully completed.
- *
- * In this case, set_debug_traps() is not used to "take over" exceptions;
- * other kernel code is modified instead to enter the kgdb functions here
- * when appropriate (see entry.S for breakpoint traps and NMI interrupts,
- * see traps.c for kernel error exceptions).
- *
- * The following gdb commands are supported:
- *
- * Command Function Return value
- *
- * g return the value of the CPU registers hex data or ENN
- * G set the value of the CPU registers OK or ENN
- *
- * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
- * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
- * XAA..AA,LLLL: Same, but data is binary (not hex) OK or ENN
- *
- * c Resume at current address SNN ( signal NN)
- * cAA..AA Continue at address AA..AA SNN
- * CNN; Resume at current address with signal SNN
- * CNN;AA..AA Resume at address AA..AA with signal SNN
- *
- * s Step one instruction SNN
- * sAA..AA Step one instruction from AA..AA SNN
- * SNN; Step one instruction with signal SNN
- * SNNAA..AA Step one instruction from AA..AA w/NN SNN
- *
- * k kill (Detach GDB)
- *
- * d Toggle debug flag
- * D Detach GDB
- *
- * Hct Set thread t for operations, OK or ENN
- * c = 'c' (step, cont), c = 'g' (other
- * operations)
- *
- * qC Query current thread ID QCpid
- * qfThreadInfo Get list of current threads (first) m<id>
- * qsThreadInfo " " " " " (subsequent)
- * qOffsets Get section offsets Text=x;Data=y;Bss=z
- *
- * TXX Find if thread XX is alive OK or ENN
- * ? What was the last sigval ? SNN (signal NN)
- * O Output to GDB console
- *
- * Remote communication protocol.
- *
- * A debug packet whose contents are <data> is encapsulated for
- * transmission in the form:
- *
- * $ <data> # CSUM1 CSUM2
- *
- * <data> must be ASCII alphanumeric and cannot include characters
- * '$' or '#'. If <data> starts with two characters followed by
- * ':', then the existing stubs interpret this as a sequence number.
- *
- * CSUM1 and CSUM2 are ascii hex representation of an 8-bit
- * checksum of <data>, the most significant nibble is sent first.
- * the hex digits 0-9,a-f are used.
- *
- * Receiver responds with:
- *
- * + - if CSUM is correct and ready for next packet
- * - - if CSUM is incorrect
- *
- * Responses can be run-length encoded to save space. A '*' means that
- * the next character is an ASCII encoding giving a repeat count which
- * stands for that many repetitions of the character preceding the '*'.
- * The encoding is n+29, yielding a printable character where n >=3
- * (which is where RLE starts to win). Don't use an n > 126.
- *
- * So "0* " means the same as "0000".

+! Entry: ARG0: destination pointer
+! ARG1: source pointer
+! ARG2: byte count
+!
+! Exit: RESULT: destination pointer
+! any other registers in the range r0-r7: trashed
+!
+! Notes: Usually one wants to do small reads and write a longword, but
+! unfortunately it is difficult in some cases to concatanate bytes
+! into a longword on the SH, so this does a longword read and small
+! writes.
+!
+! This implementation makes two assumptions about how it is called:
+!
+! 1.: If the byte count is nonzero, the address of the last byte to be
+! copied is unsigned greater than the address of the first byte to
+! be copied. This could be easily swapped for a signed comparison,
+! but the algorithm used needs some comparison.
+!
+! 2.: When there are two or three bytes in the last word of an 11-or-more
+! bytes memory chunk to b copied, the rest of the word can be read
+! without side effects.
+! This could be easily changed by increasing the minumum size of
+! a fast memcpy and the amount subtracted from r7 before L_2l_loop be 2,
+! however, this would cost a few extra cyles on average.
+! For SHmedia, the assumption is that any quadword can be read in its
+! enirety if at least one byte is included in the copy.

- * and the information saved in @bprm->security by the set_security hook.
- * Since this hook function (and its caller) are void, this hook can not

- * bprm_apply_creds is called under task_lock. @unsafe indicates various
- * reasons why it may be unsafe to change security state.
- * @bprm contains the linux_binprm structure.
- * @bprm_post_apply_creds:

- * functions which cannot be called safely under the task_lock can
- * be used. This hook is a good place to perform state changes on
- * the process such as closing open file descriptors to which access

- * Note that a security module might need to save state between
- * bprm_apply_creds and bprm_post_apply_creds to store the decision
- * on whether the process may proceed.

* is required. The flag is passed in the auxiliary table
* manual page for definitions of the @clone_flags.
* @clone_flags contains the flags indicating what should be shared.
* Return 0 if permission is granted.
- * @task_alloc_security:
- * @p contains the task_struct for child process.
- * Allocate and attach a security structure to the p->security field. The
- * security field is initialized to NULL when the task structure is
- * allocated.

- * Deallocate and clear the p->security field.
+ * @cred_free:

+ * @new points to the credentials to be modified.
+ * @secid specifies the security ID to be set
+ * The current task must be the one that nominated @secid.

+ * @kernel_create_files_as:
+ * Set the file creation context in a set of credentials to be the same as
+ * the objective context of the specified inode.
+ * @new points to the credentials to be modified.
+ * @inode points to the inode to use as a reference.
+ * The current task must be the one that nominated @inode.
+ * Return 0 if successful.

* Check permission before setting one or more of the user identity
* attributes of the current process. The @flags parameter indicates
* @id2 contains a uid.
* @flags contains one of the LSM_SETID_* values.
* Return 0 if permission is granted.
- * @task_post_setuid:
+ * @task_fix_setuid:
* Update the module's state after setting one or more of the user
* identity attributes of the current process. The @flags parameter
* indicates which of the set*uid system calls invoked this hook. If
- * @flags is LSM_SETID_FS, then @old_ruid is the old fs uid and the other

- * Return 0 if permission is granted, and non-zero if the security module
- * has taken responsibility (setting *rc_p) for the prctl call.
- * @task_reparent_to_init:
- * Set the security attributes in @p->security for a kernel thread that
- * is being reparented to the init task.
- * @p contains the task_struct for the kernel thread.
+ * Return -ENOSYS if no-one wanted to handle this op, any other value to
+ * cause prctl() to return immediately with that value.
* @task_to_inode:
* Set the security attributes for an inode based on an associated task's
* security attributes, e.g. for /proc/pid inodes.
* See whether a specific operational right is granted to a process on a
* key.
* @key_ref refers to the key (key pointer + possession attribute bit).
- * @context points to the process to provide the context against which to
+ * @cred points to the credentials to provide the context against which to
* evaluate the security data on the key.
* @perm describes the combination of permissions required of this key.
* Return 1 if permission granted, 0 if permission denied and -ve it the
* @child process.
* Security modules may also want to perform a process tracing check
* during an execve in the set_security or apply_creds hooks of
+ * tracing check during an execve in the bprm_set_creds hook of
* binprm_security_ops if the process is being traced and its security
* attributes would be changed by the execve.
* @child contains the task_struct structure for the target process.
* @inheritable contains the inheritable capability set.
* @permitted contains the permitted capability set.
* Return 0 if the capability sets were successfully obtained.
- * @capset_check:
- * Check permission before setting the @effective, @inheritable, and
- * @permitted capability sets for the @target process.
- * Caveat: @target is also set to current if a set of processes is
- * specified (i.e. all processes other than current and init or a
- * particular process group). Hence, the capset_set hook may need to
- * revalidate permission to the actual target process.
- * @target contains the task_struct structure for target process.
- * @effective contains the effective capability set.
- * @inheritable contains the inheritable capability set.
- * @permitted contains the permitted capability set.
- * Return 0 if permission is granted.
- * @capset_set:
+ * @capset:
* Set the @effective, @inheritable, and @permitted capability sets for
- * the @target process. Since capset_check cannot always check permission
- * to the real @target process, this hook may also perform permission
- * checking to determine if the current process is allowed to set the
- * capability sets of the @target process. However, this hook has no way
- * of returning an error due to the structure of the sys_capset code.
- * @target contains the task_struct structure for target process.

* Check whether the @tsk process has the @cap capability.
* @tsk contains the task_struct for the process.

- If the irq handler handles some data on the DMA buffer, it should

- However, there are two remaining issues:
- 1. The substream pointer you try to lock isn't protected _before_
- this lock yet.
- 2. snd_pcm_period_elapsed() itself acquires the lock.
- The requirement of another lock is because of 1. When you get
- chip->playback_substream, it's not protected.
- Keeping this lock while snd_pcm_period_elapsed() assures the substream
- is still protected (at least, not released). And the other status is

Normally ASoC codec drivers are only built if a machine driver which
uses them is also built since they are only usable with a machine
driver. Selecting this option will allow these drivers to be built
without an explicit machine driver for test and development purposes.
+ Support for the bus types used to access the codecs to be built must
+ be selected separately.
+
If unsure select "N".

+ turn off the ADC/DAC when this callback is invoked and turn it back
+ on when needed. Unfortunately this will result in a very light bump
+ (it can be audible only with good earphones). If this bothers you
+ just comment this line, you will have slightly higher power
+ consumption . Please note that sending the L3 command for ADC is
+ enough to make the bump, so it doesn't make difference if you
