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.

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.

2002-08-06Updates from Rusty Russell to:Rik Faith
1) Remove redundant header inclusion 2) Silence bitop on non-long argument warnings (change int to long) 3) Move to ISO C (gcc 2.6) initializers (accepted by older gccs also) All of these are syntax changes that should not impact functionality.
