2008-04-14Fix up buffer manager locking.Thomas Hellstrom
2008-03-05drm: Fix for non-coherent DMA PowerPCBenjamin Herrenschmidt
This patch fixes bits of the DRM so to make the radeon DRI work on non-cache coherent PCI DMA variants of the PowerPC processors. It moves the few places that needs change to wrappers to that other architectures with similar issues can easily add their own changes to those wrappers, at least until we have more useful generic kernel API.

2008-03-06drm: reorganise minor number handling using code from modesetting branchDave Airlie
Rip out the whole head thing and replace it with an idr and drm_minor structure.
2008-01-03drm: cleanup DRM_DEBUG() parametersMárton Németh
As DRM_DEBUG macro already prints out the __FUNCTION__ string (see drivers/char/drm/drmP.h), it is not worth doing this again. At some other places the ending "\n" was added. airlied:- I cleaned up a few that this patch missed also
2007-12-21Rename inappropriately named 'mask' fields to 'proposed_flags' instead.Keith Packard
Flags pending validation were stored in a misleadingly named field, 'mask'. As 'mask' is already used to indicate pieces of a flags field which are changing, it seems better to use a name reflecting the actual purpose of this field. I chose 'proposed_flags' as they may not actually end up in 'flags', and in an case will be modified when they are moved over. This affects the API, but not ABI of the user-mode interface.
2007-11-22drm: major whitespace/coding style realignment with kernelDave Airlie
2007-11-05drm: more kernel coding style cleanupsDave Airlie
2007-10-21Remove the need for the hardware lock in the buffer manager.Thomas Hellstrom
Add interface entry cleaning a memory type without touching NO_EVICT buffers.
2007-07-20Replace filp in ioctl arguments with drm_file *file_priv.Eric Anholt
As a fallout, replace filp storage with file_priv storage for "unique identifier of a client" all over the DRM. There is a 1:1 mapping, so this should be a noop. This could be a minor performance improvement, as everything on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls went the other direction.
2007-07-16drm: detypedef ttm/bo/fence codeDave Airlie

2007-06-29Fence object reference / dereference cleanup.Thomas Hellstrom
Buffer object dereference cleanup. Add a struct drm_device member to fence objects: This can simplify code, particularly in drivers.
2007-05-26drm: cleanup use of Linux list handling macrosDave Airlie
This makes the drms use of the list handling macros a lot cleaner and more along the lines of how they should be used.

2007-04-26drm: nopfn warning on 64-bitDave Airlie
2007-04-03Make sure CMA (Can't map aperture) pages are mapped uncached.Thomas Hellstrom
(Should really make this write-combined using PATs, at some point).
2007-03-24vm: cleanup drm_vm.c along lines of cleanups queued for kernelDave Airlie
2007-03-23cleanup more whitespace from ttm mergeDave Airlie

2007-02-10Various bugfixes.Thomas Hellstrom
2007-02-09Fix evict_mutex locking range.Thomas Hellstrom
Implement unmappable buffers. (fault moves them to mappable when needed). Various bugfixes.
2007-02-08Fix mm_block leak.Thomas Hellstrom
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.
2007-02-06Simplify pci map vs no pci map choice.Thomas Hellstrom
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).
2007-02-01Fix missing ttm_open_vma call from previous commit.Thomas Hellstrom
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

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.

2006-10-17Add 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.

2006-10-02Bug 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.
