Dave Airlie 656c3a3737 [SPARC]: Respect vm_page_prot in io_remap_page_range().
Make sure the callers do a pgprot_noncached() on
    vma->vm_page_prot.

Dave Airlie 0ab48b0841 [PATCH] mm: incorrect VM_FAULT_OOM returns from drivers
Some drivers are returning OOM when it is not in response to a memory

Thomas Hellstrom f22f89e6b3 Add vma list memory usage to memory accounting.

Thomas Hellstrom 3070389367 Compatibility code for 2.6.15-2.6.18. It is ugly but a little comfort is that
it will go away in the mainstream kernel.
Some bugfixes, mainly in error paths.
2006-10-11 22:21:01 +02:00
Thomas Hellstrom f2db76e2f2 Big update:
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.

Thomas Hellstrom 126673d62a Keep hashed user tokens, with the following changes:
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.
2006-07-11 14:37:37 +00:00
Thomas Hellstrom a392349691 Change drm Map handles to be arbitrary 32-bit hash tokens in the range
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.

Eric Anholt 9cad6fb4e0 Bugzilla #3217: Create a new __drm_pci_free which is used internally in
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.

Eric Anholt ec111d70fe Convert BSD code to mostly use bus_dma, the dma abstraction for dealing
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.

Dave Airlie 385f927692 Some ia64 platforms may not support write combining on all type of memory,
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?

Felix Kuehling ed165a2529 Added a new DRM map type _DRM_CONSISTENT for consistent PCI memory. It uses
