(Should really make this write-combined using PATs, at some point).

Some other minor fixes.
2007-02-08Simplify external ttm page allocation.Thomas Hellstrom
Implement a memcpy fallback for copying between buffers.
2007-02-07Fix a stray unlock_kernel() in drm_vm.cThomas Hellstrom
Add a file for memory move helpers, drm_bo_move.c Implement generic memory move. Cached, no_move and unmapped memory temporarily broken.

2007-02-02Make also later kernels work with buffer object vmThomas Hellstrom
and clean up some function names.
2007-02-02Make vm handle buffer objects instead of ttm objects.Thomas Hellstrom
Remove ttm objects. Make vm aware of PCI memory type buffer objects. (Only works for pre 2.6.16 kernels for now).

Honour the ttm backend cant-use-aperture flag.
2007-02-01Protect drm_mmap against disappearing maps.Thomas Hellstrom
The map lists and hash tables are protected using dev->struct_mutex, but drm_mmap strangely never locked this mutex.
2007-01-08drm: remove drm_follow_page, and drm_ioremap and ioremapfreeChristoph Hellwig
This comes from the Re: [patch] paravirt: isolate module ops on lkml It needs some testing, please report any regressions caused. Signed-off-by: Dave Airlie <airlied@linux.ie>

2006-12-27Proper allocation of AGP pages for ttms.Thomas Hellstrom
2006-12-19Security fix. Zero pages before they are handed to user space.Thomas Hellstrom
TTM pages were not cleared when allocated and handed to user space. Sensitive information may leak.
2006-12-19drm: remove all 2.4 support for drm development tree.Dave Airlie
Bye bye 2.4 you served us well..
2006-12-19[SPARC]: Respect vm_page_prot in io_remap_page_range().Dave Airlie
Make sure the callers do a pgprot_noncached() on vma->vm_page_prot. Pointed out by Hugh Dickens. Signed-off-by: David S. Miller <davem@davemloft.net>
2006-12-19[PATCH] mm: incorrect VM_FAULT_OOM returns from driversDave Airlie
Some drivers are returning OOM when it is not in response to a memory shortage. Signed-off-by: Nick Piggin <npiggin@suse.de>

2006-10-17Add vma list memory usage to memory accounting.Thomas Hellstrom
Use byte unit for /proc printout of memory usage for small sizes to be able to detect memory allocation bugs more easily.
2006-10-17Add memory usage accounting to avoid DOS problems.Thomas Hellstrom
2006-10-11Compatibility code for 2.6.15-2.6.18. It is ugly but a little comfort is thatThomas Hellstrom
it will go away in the mainstream kernel. Some bugfixes, mainly in error paths.
2006-10-11Big update:Thomas Hellstrom
Adapt for new functions in the 2.6.19 kernel. Remove the ability to have multiple regions in one TTM. This simplifies a lot of code. Remove the ability to access TTMs from user space. We don't need it anymore without ttm regions. Don't change caching policy for evicted buffers. Instead change it only when the buffer is accessed by the CPU (on the first page fault). This tremendously speeds up eviction rates. Current code is safe for kernels <= 2.6.14. Should also be OK with 2.6.19 and above.
2006-10-10Use a nopage-based approach to fault in pfns.Thomas Hellstrom
2006-10-02Bug 6242: [mach64] Use private DMA buffers, part #3.George Sapountzis
Add DRM_PCI_BUFFER_RO flag for mapping PCI DMA buffer read-only. An additional flag is needed, since PCI DMA buffers do not have an associated map.

2006-07-24switch drm to use Linux mutexes instead of semaphore.Dave Airlie
I hope the fallback compat code works if not shout at me.
2006-07-11Keep hashed user tokens, with the following changes:Thomas Hellstrom
32-bit physical device addresses are mapped directly to user-tokens. No duplicate maps are allowed, and the addresses are assumed to be outside of the range 0x10000000 through 0x30000000. The user-token is identical to the 32-bit physical start-address of the map. 64-bit physical device addressed are mapped to user-tokens in the range 0x10000000 to 0x30000000 with page-size increments. The user_token should not be interpreted as an address. Other map types, like upcoming TTM maps are mapped to user-tokens in the range 0x10000000 to 0x30000000 with page-size increments. The user_token should not be interpreted as an address. This keeps compatibility with buggy drivers, while still implementing a hashed map lookup. The SiS and via device driver major bumps are reverted.
2006-07-10Change drm Map handles to be arbitrary 32-bit hash tokens in the rangeThomas Hellstrom
0x10000000 to 0x90000000 in PAGE_SIZE increments. Implement hashed map lookups. This potentially breaks both 2D and 3D drivers. If so, the corresponding 2D and 3D driver should be fixed, and it's corresponding drm device driver should have its major bumped as soon as possible. Bump sis and via drm device driver majors. The SiS and Unichrome 3D drivers are fixed in Mesa CVS HEAD and mesa_6_4_branch.
