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. 2006-02-18major realigment of DRM CVS with kernel code, makes integration much easierDave Airlie 2005-11-29Fix from Hugh Dickins for consistent mappingDave Airlie 2005-08-20remove checks that make ppc64 not work properly... also fix ppc64 check..Dave Airlie we should be safe doing this.. 2005-08-16add Egberts 32/64 bit patch (its in kernel already...)Dave Airlie 2005-06-04misc cleanup patch from Adrian BunkDave Airlie 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. 2004-10-23fix pfn vs page for older kernels (2.6.9-rc kernels many not work..)Dave Airlie 2004-10-22Bring in patch from kernel for remap_pfn_rangeJon Smirl 2004-10-18Update Doxygen configuration & comments.Jose Fonseca 2004-10-12Breakout heads into their own data structures.Jon Smirl 2004-10-10Rename fn_tbl to driver.

A few filesJon Smirl weren't Lindent's because their comments didn't convert very well. A bunch of other minor clean up with no code implact included. 2004-09-30Make fops per driver instead of global, remove default flush, poll, readJon Smirl functions 2004-09-27First check in for DRM that splits core from personality modulesJon Smirl 2004-09-20Felix's fix for map request smaller than permanent map sizeJon Smirl 2004-09-05merge back bunch of whitespace and misc changes from kernelDave Airlie 2004-09-05bad code copy for alpha.. fix the member namesDave Airlie 2004-09-05make the AMD64 check a compat thingDave Airlie 2004-09-04Fixup OS_HAS_AGP/OS_HAS_MTRR along lines of patches going to kernel, asDave Airlie suggested by Arjan..
