Build fixes for powerpc. Reported by Katerina Barone-Adesi

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.
2006-10-02Allow for 44 bit user-tokens (or drm_file offsets)Thomas Hellstrom
2006-09-27Adapt to architecture-specific hooks for gatt pages.Thomas Hellstrom
2006-09-14Remove the use of reserved pages, and use locked pages instead.Thomas Hellstrom
Update compatibility for latest linux versions.
2006-09-12More bugfixes.Thomas Hellstrom
Disable the i915 IRQ turnoff for now since it seems to be causing problems.

2006-08-28drm: lots of small cleanups and whitespace issues fixed upDave Airlie
remove a mach64 warning, align a lot of things from linux kernel
2006-08-25Module protection map access is moving into mainline kernels.Thomas Hellstrom
Update drm_compat accordingly. (Reported by Dave Airlie)

Buffer object code.

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.

we should be safe doing this..

2005-05-28Bugzilla #3217: Create a new __drm_pci_free which is used internally inEric Anholt
linux-core to free pci memory without freeing the structure. Linux-core internals often create pci dma handle structures on the stack due to the lack of a drm_local_map_t to store them in properly. Fix the original drm_pci_free to actually free the dma handle structure instead of leaking it. Signed-off-by: Sergey Vlasov <vsu@altlinux.ru>
2005-04-26Convert BSD code to mostly use bus_dma, the dma abstraction for dealingEric Anholt
with IOMMUs and such. There is one usage of the forbidden vtophys() left in drm_scatter.c which will be fixed up soon. This required a KPI change for drm_pci_alloc/free() to return/use a drm_dma_handle_t that keeps track of os-specific bits, rather than just passing around the vaddr/busaddr/size. Submitted by: Tonnerre Lombard (partially) Tested on: FreeBSD: Rage128 AGP/PCI Linux: Savage4 AGP/PCI
2005-03-27Some ia64 platforms may not support write combining on all type of memory,Dave Airlie
so we need to consult the EFI memory map before we try to set the write combine attribute of a page. This patch will try to map a page write combined if it's not an AGP page and the EFI memory map says it's ok, otherwise it falls back to a regular, uncached mapping. Can someone please apply this to the drm tree? From: Jesse Barnes
2005-01-12Use virt_to_page instead of vmalloc_to_page in drm_do_vm_shm_nopage forFelix Kuehling
consistent pages allocated with drm_pci_alloc.
2005-01-01Added a new DRM map type _DRM_CONSISTENT for consistent PCI memory. It usesFelix Kuehling
drm_pci_alloc/free for allocating/freeing the memory. Only implemented in the Linux DRM so far.

2004-09-30Lindent of core build. Drivers checked for no binary diffs. A few filesJon Smirl
