+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+ The 3rd party driver is a specification of an API to integrate the IMG POWERVR
+ Services driver with a 3rd Party 'buffer device'. It is NOT a specification for
+ a 'buffer device' driver, rather a specification to extend the API for a
+ pre-existing driver for the 'buffer device' hardware.
+
+ The 3rd party driver interface provides IMG POWERVR client drivers (e.g. PVR2D)
+ with an API abstraction of the system's underlying buffer device hardware,
+ allowing the client drivers to indirectly control the buffer device hardware
+ and access its associated memory.
+
+ Functions of the API include
+ - query buffer device surface attributes (width, height, stride, pixel format,
+ CPU physical and virtual address)
+
+ Note: having queried surface attributes the client drivers are able to map the
+ buffer device memory to any IMG POWERVR Services device by calling
+ PVRSRVMapDeviceClassMemory with the buffer device surface handle.
+
+ This code is intended to be an example of how a pre-existing buffer device
+ driver may be extended to support the 3rd Party buffer device interface to
+ POWERVR Services
+ - IMG is not providing a buffer device driver implementation.

+ the kernel varies the major number it assigns. The number

+ mknod /dev/bc_example c ? 0
+
+ where ? is the major number reported by the printk() - look
+ at the boot log using `dmesg' to see this).

+ The 3rd party driver is a specification of an API to integrate the IMG POWERVR
+ Services driver with 3rd Party display hardware. It is NOT a specification for
+ a display controller driver, rather a specification to extend the API for a
+ pre-existing driver for the display hardware.
+
+ The 3rd party driver interface provides IMG POWERVR client drivers (e.g. PVR2D)
+ with an API abstraction of the system's underlying display hardware, allowing
+ the client drivers to indirectly control the display hardware and access its
+ associated memory.
+
+ Functions of the API include
+ - query primary surface attributes (width, height, stride, pixel format, CPU
+ physical and virtual address)
+ - swap/flip chain creation and subsequent query of surface attributes
+ - asynchronous display surface flipping, taking account of asynchronous read
+ (flip) and write (render) operations to the display surface
+
+ Note: having queried surface attributes the client drivers are able to map the
+ display memory to any IMG POWERVR Services device by calling
+ PVRSRVMapDeviceClassMemory with the display surface handle.
+
+ This code is intended to be an example of how a pre-existing display driver may
+ be extended to support the 3rd Party Display interface to POWERVR Services
+ - IMG is not providing a display driver implementation.

+ The 3rd party driver is a specification of an API to integrate the IMG POWERVR
+ Services driver with 3rd Party display hardware. It is NOT a specification for
+ a display controller driver, rather a specification to extend the API for a
+ pre-existing driver for the display hardware.
+
+ The 3rd party driver interface provides IMG POWERVR client drivers (e.g. PVR2D)
+ with an API abstraction of the system's underlying display hardware, allowing
+ the client drivers to indirectly control the display hardware and access its
+ associated memory.
+
+ Functions of the API include
+ - query primary surface attributes (width, height, stride, pixel format, CPU
+ physical and virtual address)
+ - swap/flip chain creation and subsequent query of surface attributes
+ - asynchronous display surface flipping, taking account of asynchronous read
+ (flip) and write (render) operations to the display surface
+
+ Note: having queried surface attributes the client drivers are able to map the
+ display memory to any IMG POWERVR Services device by calling
+ PVRSRVMapDeviceClassMemory with the display surface handle.
+
+ This code is intended to be an example of how a pre-existing display driver may
+ be extended to support the 3rd Party Display interface to POWERVR Services
+ - IMG is not providing a display driver implementation.

+ The 3rd party driver is a specification of an API to integrate the IMG POWERVR
+ Services driver with 3rd Party display hardware. It is NOT a specification for
+ a display controller driver, rather a specification to extend the API for a
+ pre-existing driver for the display hardware.
+
+ The 3rd party driver interface provides IMG POWERVR client drivers (e.g. PVR2D)
+ with an API abstraction of the system's underlying display hardware, allowing
+ the client drivers to indirectly control the display hardware and access its
+ associated memory.
+
+ Functions of the API include
+ - query primary surface attributes (width, height, stride, pixel format, CPU
+ physical and virtual address)
+ - swap/flip chain creation and subsequent query of surface attributes
+ - asynchronous display surface flipping, taking account of asynchronous read
+ (flip) and write (render) operations to the display surface
+
+ Note: having queried surface attributes the client drivers are able to map the
+ display memory to any IMG POWERVR Services device by calling
+ PVRSRVMapDeviceClassMemory with the display surface handle.
+
+ This code is intended to be an example of how a pre-existing display driver may
+ be extended to support the 3rd Party Display interface to POWERVR Services
+ - IMG is not providing a display driver implementation.

+ The 3rd party driver is a specification of an API to integrate the IMG POWERVR
+ Services driver with 3rd Party display hardware. It is NOT a specification for
+ a display controller driver, rather a specification to extend the API for a
+ pre-existing driver for the display hardware.
+
+ The 3rd party driver interface provides IMG POWERVR client drivers (e.g. PVR2D)
+ with an API abstraction of the system's underlying display hardware, allowing
+ the client drivers to indirectly control the display hardware and access its
+ associated memory.
+
+ Functions of the API include
+ - query primary surface attributes (width, height, stride, pixel format, CPU
+ physical and virtual address)
+ - swap/flip chain creation and subsequent query of surface attributes
+ - asynchronous display surface flipping, taking account of asynchronous read
+ (flip) and write (render) operations to the display surface
+
+ Note: having queried surface attributes the client drivers are able to map the
+ display memory to any IMG POWERVR Services device by calling
+ PVRSRVMapDeviceClassMemory with the display surface handle.
+
+ This code is intended to be an example of how a pre-existing display driver may
+ be extended to support the 3rd Party Display interface to POWERVR Services
+ - IMG is not providing a display driver implementation.

+ The 3rd party driver is a specification of an API to integrate the IMG POWERVR
+ Services driver with 3rd Party display hardware. It is NOT a specification for
+ a display controller driver, rather a specification to extend the API for a
+ pre-existing driver for the display hardware.
+
+ The 3rd party driver interface provides IMG POWERVR client drivers (e.g. PVR2D)
+ with an API abstraction of the system's underlying display hardware, allowing
+ the client drivers to indirectly control the display hardware and access its
+ associated memory.
+
+ Functions of the API include
+ - query primary surface attributes (width, height, stride, pixel format, CPU
+ physical and virtual address)
+ - swap/flip chain creation and subsequent query of surface attributes
+ - asynchronous display surface flipping, taking account of asynchronous read
+ (flip) and write (render) operations to the display surface
+
+ Note: having queried surface attributes the client drivers are able to map the
+ display memory to any IMG POWERVR Services device by calling
+ PVRSRVMapDeviceClassMemory with the display surface handle.
+
+ This code is intended to be an example of how a pre-existing display driver may
+ be extended to support the 3rd Party Display interface to POWERVR Services
+ - IMG is not providing a display driver implementation.

+ The 3rd party driver is a specification of an API to integrate the IMG POWERVR
+ Services driver with 3rd Party display hardware. It is NOT a specification for
+ a display controller driver, rather a specification to extend the API for a
+ pre-existing driver for the display hardware.
+
+ The 3rd party driver interface provides IMG POWERVR client drivers (e.g. PVR2D)
+ with an API abstraction of the system's underlying display hardware, allowing
+ the client drivers to indirectly control the display hardware and access its
+ associated memory.
+
+ Functions of the API include
+ - query primary surface attributes (width, height, stride, pixel format, CPU
+ physical and virtual address)
+ - swap/flip chain creation and subsequent query of surface attributes
+ - asynchronous display surface flipping, taking account of asynchronous read
+ (flip) and write (render) operations to the display surface
+
+ Note: having queried surface attributes the client drivers are able to map the
+ display memory to any IMG POWERVR Services device by calling
+ PVRSRVMapDeviceClassMemory with the display surface handle.
+
+ This code is intended to be an example of how a pre-existing display driver may
+ be extended to support the 3rd Party Display interface to POWERVR Services
+ - IMG is not providing a display driver implementation.

+ The 3rd party driver is a specification of an API to integrate the IMG POWERVR
+ Services driver with 3rd Party display hardware. It is NOT a specification for
+ a display controller driver, rather a specification to extend the API for a
+ pre-existing driver for the display hardware.
+
+ The 3rd party driver interface provides IMG POWERVR client drivers (e.g. PVR2D)
+ with an API abstraction of the system's underlying display hardware, allowing
+ the client drivers to indirectly control the display hardware and access its
+ associated memory.
+
+ Functions of the API include
+ - query primary surface attributes (width, height, stride, pixel format, CPU
+ physical and virtual address)
+ - swap/flip chain creation and subsequent query of surface attributes
+ - asynchronous display surface flipping, taking account of asynchronous read
+ (flip) and write (render) operations to the display surface
+
+ Note: having queried surface attributes the client drivers are able to map the
+ display memory to any IMG POWERVR Services device by calling
+ PVRSRVMapDeviceClassMemory with the display surface handle.
+
+ This code is intended to be an example of how a pre-existing display driver may
+ be extended to support the 3rd Party Display interface to POWERVR Services
+ - IMG is not providing a display driver implementation.

-/** @file drm_gem.c
- *
- * This file provides some of the base ioctls and library routines for
- * the graphics memory manager implemented by each device driver.
- *
- * Because various devices have different requirements in terms of
- * synchronization and migration strategies, implementing that is left up to
- * the driver, and all that the general API provides should be generic --
- * allocating objects, reading/writing data with the cpu, freeing objects.
- * Even there, platform-dependent optimizations for reading/writing data with
- * the CPU mean we'll likely hook those out to driver-specific calls. However,
- * the DRI2 implementation wants to have at least allocate/mmap be generic.
- *
- * The goal was to have swap-backed object allocation managed through
- * struct file. However, file descriptors as handles to a struct file have
- * two major failings:
- * - Process limits prevent more than 1024 or so being used at a time by
- * default.
- * - Inability to allocate high fds will aggravate the X Server's select()
- * handling, and likely that of many GL client applications as well.
- *
- * This led to a plan of using our own integer IDs (called handles, following
- * DRM terminology) to mimic fds, and implement the fd syscalls we need as
- * ioctls. The objects themselves will still include the struct file so
- * that we can transition to fds if the required kernel infrastructure shows
- * up at a later date, and as our interface with shmfs for memory allocation.
- */

-/*
- * We make up offsets for buffer objects so we can recognize them at

- * Generic simple memory manager implementation. Intended to be used as a base
- * class implementation for more advanced memory managers.
- *
- * Note that the algorithm used is quite simple and there might be substantial
- * performance gains if a smarter free list is implemented. Currently it is just an
- * unordered stack of free regions. This could easily be improved if an RB-tree
- * is used instead. At least if we expect heavy fragmentation.
- *
- * Aligned allocations can also see improvement.

+@Title Resource Allocator
+@Copyright Copyright (c) Imagination Technologies Ltd. All Rights Reserved
+@Description
+ Implements generic resource allocation. The resource
+ allocator was originally intended to manage address spaces in
+ practice the resource allocator is generic and can manages arbitrary
+ sets of integers.
+
+ Resources are allocated from arenas. Arena's can be created with an
+ initial span of resources. Further resources spans can be added to
+ arenas. A call back mechanism allows an arena to request further
+ resource spans on demand.
+
+ Each arena maintains an ordered list of resource segments each
+ described by a boundary tag. Each boundary tag describes a segment
+ of resources which are either 'free', available for allocation, or
+ 'busy' currently allocated. Adjacent 'free' segments are always
+ coallesced to avoid fragmentation.
+
+ For allocation, all 'free' segments are kept on lists of 'free'
+ segments in a table index by pvr_log2(segment size). ie Each table index
+ n holds 'free' segments in the size range 2**(n-1) -> 2**n.
+
+ Allocation policy is based on an *almost* best fit
+ stratedy. Choosing any segment from the appropriate table entry
+ guarantees that we choose a segment which is with a power of 2 of
+ the size we are allocating.
+
+ Allocated segments are inserted into a self scaling hash table which
+ maps the base resource of the span to the relevant boundary
+ tag. This allows the code to get back to the bounary tag without
+ exporting explicit boundary tag references through the API.
+
+ Each arena has an associated quantum size, all allocations from the
+ arena are made in multiples of the basic quantum.
+
+ On resource exhaustion in an arena, a callback if provided will be
+ used to request further resources. Resouces spans allocated by the
+ callback mechanism are delimited by special boundary tag markers of
+ zero span, 'span' markers. Span markers are never coallesced. Span
+ markers are used to detect when an imported span is completely free
+ and can be deallocated by the callback mechanism.

+ Incoming 32bit Device Virtual Addresses are deconstructed into 3 fields:
+ ---------------------------------------------------------
+ | PD Index/tag: | PT Index: | DP offset: |
+ | bits 31:22 | bits 21:n | bits (n-1):0 |
+ ---------------------------------------------------------
+ where typically n=12 for a standard 4k DP
+ but n=16 for a 64k DP
+
+ MMU page directory (PD), pagetable (PT) and data page (DP) config:
+ PD:
+ - always one page per address space
+ - up to 4k in size to span 4Gb (32bit)
+ - contains up to 1024 32bit entries
+ - entries are indexed by the top 12 bits of an incoming 32bit device virtual address
+ - the PD entry selected contains the physical address of the PT to
+ perform the next stage of the V to P translation
+
+ PT:
+ - size depends on the DP size, e.g. 4k DPs have 4k PTs but 16k DPs have 1k PTs
+ - each PT always spans 4Mb of device virtual address space irrespective of DP size
+ - number of entries in a PT depend on DP size and ranges from 1024 to 4 entries
+ - entries are indexed by the PT Index field of the device virtual address (21:n)
+ - the PT entry selected contains the physical address of the DP to access
+
+ DP:
+ - size varies from 4k to 4M in multiple of 4 steppings
+ - DP offset field of the device virtual address ((n-1):0) is used as a byte offset

+
+ Readable proc-filesystem entries under /proc/pvr are created with
+ CreateProcEntries(). These can be read at runtime to get information about

+
+ __exit places the function in a special memory section that the kernel frees
+ once the function has been run. Refer also to module_exit() macro call below.
+ Note that the for LDM on MontaVista kernels, the positioning of the driver
+ de-registration is the opposite way around than would be suggested by the
+ registration case or the 2,6 kernel case. This is the correct way to do it
+ and the kernel panics if you change it. You have been warned.

+ - USAGE -
+
+ The list functions work with any structure that provides the fields psNext and
+ ppsThis. In order to make a function available for a given type, it is required
+ to use the funcion template macro that creates the actual code.
+
+ There are 4 main types of functions:
+ - INSERT : given a pointer to the head pointer of the list and a pointer to
+ the node, inserts it as the new head.
+ - REMOVE : given a pointer to a node, removes it from its list.
+ - FOR EACH : apply a function over all the elements of a list.
+ - ANY : apply a function over the elements of a list, until one of them
+ return a non null value, and then returns it.
+
+ The two last functions can have a variable argument form, with allows to pass
+ additional parameters to the callback function. In order to do this, the
+ callback function must take two arguments, the first is the current node and
+ the second is a list of variable arguments (va_list).
+
+ The ANY functions have also another for wich specifies the return type of the
+ callback function and the default value returned by the callback function.
