=====
This document is designed to provide a list of the minimum levels of
-software necessary to run the 2.6 kernels, as well as provide brief
-instructions regarding any other "Gotchas" users may encounter when
-trying life on the Bleeding Edge. If upgrading from a pre-2.4.x
-kernel, please consult the Changes file included with 2.4.x kernels for
-additional information; most of that information will not be repeated
-here. Basically, this document assumes that your system is already
-functional and running at least 2.4.x kernels.
+software necessary to run the 3.0 kernels.
This document is originally based on my "Changes" file for 2.0.x kernels
and therefore owes credit to the same people as that file (Jared Mauch,
encountered a bug! If you're unsure what version you're currently
running, the suggested command should tell you.
-Again, keep in mind that this list assumes you are already
-functionally running a Linux 2.4 kernel. Also, not all tools are
-necessary on all systems; obviously, if you don't have any ISDN
-hardware, for example, you probably needn't concern yourself with
-isdn4k-utils.

If the unthinkable happens and your kernel oopses, you may need the
ksymoops tool to decode it, but in most cases you don't.
-In the 2.6 kernel it is generally preferred to build the kernel with
-CONFIG_KALLSYMS so that it produces readable dumps that can be used as-is
-(this also produces better output than ksymoops).
-If for some reason your kernel is not build with CONFIG_KALLSYMS and
-you have no way to rebuild and reproduce the Oops with that option, then
-you can still decode that Oops with ksymoops.

+In ancient (2.4 and earlier) kernels, the nfs server needed to know
+about any client that expected to be able to access files via NFS. This
information would be given to the kernel by "mountd" when the client
mounted the filesystem, or by "exportfs" at system startup. exportfs
would take information about active clients from /var/lib/nfs/rmtab.
fail-over. Even when the system is working well, rmtab suffers from
getting lots of old entries that never get removed.
-With 2.6 we have the option of having the kernel tell mountd when it
-gets a request from an unknown host, and mountd can give appropriate
-export information to the kernel. This removes the dependency on
-rmtab and means that the kernel only needs to know about currently
-active clients.

Who: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
----------------------------
+
+What: For VIDIOC_S_FREQUENCY the type field must match the device node's type.
+ If not, return -EINVAL.
+When: 3.2
+Why: It makes no sense to switch the tuner to radio mode by calling
+ VIDIOC_S_FREQUENCY on a video node, or to switch the tuner to tv mode by
+ calling VIDIOC_S_FREQUENCY on a radio node. This is the first step of a
+ move to more consistent handling of tv and radio tuners.
+Who: Hans Verkuil <hans.verkuil@cisco.com>
+
+----------------------------
+
+What: Opening a radio device node will no longer automatically switch the
+ tuner mode from tv to radio.
+When: 3.3
+Why: Just opening a V4L device should not change the state of the hardware
+ like that. It's very unexpected and against the V4L spec. Instead, you
+ switch to radio mode by calling VIDIOC_S_FREQUENCY. This is the second
+ and last step of the move to consistent handling of tv and radio tuners.

The above is always safe. It will disable interrupts _locally_, but the
spinlock itself will guarantee the global lock, so it will guarantee that
there is only one thread-of-control within the region(s) protected by that
-lock. This works well even under UP. The above sequence under UP
-essentially is just the same as doing
-
- unsigned long flags;
-
- save_flags(flags); cli();
- ... critical section ...
- restore_flags(flags);
-
-so the code does _not_ need to worry about UP vs SMP issues: the spinlocks
-work correctly under both (and spinlocks are actually more efficient on
-architectures that allow doing the "save_flags + cli" in one operation).
+lock. This works well even under UP also, so the code does _not_ need to
+worry about UP vs SMP issues: the spinlocks work correctly under both.
NOTE! Implications of spin_locks for memory are further described in:
spinlock for most things - using more than one spinlock can make things a
lot more complex and even slower and is usually worth it only for
sequences that you _know_ need to be split up: avoid it at all cost if you
-aren't sure). HOWEVER, it _does_ mean that if you have some code that does
-
- cli();
- .. critical section ..
- sti();
-
-and another sequence that does
-
- spin_lock_irqsave(flags);
- .. critical section ..
- spin_unlock_irqrestore(flags);
-
-then they are NOT mutually exclusive, and the critical regions can happen
-at the same time on two different CPU's. That's fine per se, but the
-critical regions had better be critical for different things (ie they
-can't stomp on each other).
-
-The above is a problem mainly if you end up mixing code - for example the
-routines in ll_rw_block() tend to use cli/sti to protect the atomicity of
-their actions, and if a driver uses spinlocks instead then you should
-think about issues like the above.
+aren't sure).
This is really the only really hard part about spinlocks: once you start
using spinlocks they tend to expand to areas you might not have noticed
The single spin-lock primitives above are by no means the only ones. They
are the most safe ones, and the ones that work under all circumstances,
-but partly _because_ they are safe they are also fairly slow. They are
-much faster than a generic global cli/sti pair, but slower than they'd
-need to be, because they do have to disable interrupts (which is just a
-single instruction on a x86, but it's an expensive one - and on other
-architectures it can be worse).
