2007-04-18Simplify the ttm backend interface and the agp ttm backend.Thomas Hellstrom
2007-03-19whitespace cleanup pending a kernel mergeDave Airlie
2007-02-12Lindent.Thomas Hellstrom
2007-02-09I915 accelerated blit copy functional.Thomas Hellstrom
Fixed - to System memory copies are implemented by flipping in a cache-coherent TTM, blitting to it, and then flipping it out.
2007-02-09Fix copyright statements.Thomas Hellstrom
2007-02-08Simplify external ttm page allocation.Thomas Hellstrom
Implement a memcpy fallback for copying between buffers.
2007-02-07Checkpoint commit.Thomas Hellstrom
Flag handling and memory type selection cleanup. glxgears won't start.
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.
2007-01-09ttm: make ttm alloc/free into alloc_pages/free_pagesDave Airlie
Add a vmalloc flag to the page flags
2006-12-27Proper allocation of AGP pages for ttms.Thomas Hellstrom
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.
2006-10-30Bugzilla Bug #8819Thomas Hellstrom
Build fixes for powerpc. Reported by Katerina Barone-Adesi
2006-10-26Add a one-page hole in the file offset space between buffers.Thomas Hellstrom
2006-10-21The CPU cache must be flushed _before_ we start modifying the kernel map ptes,Thomas Hellstrom
otherwise data will be missing, which becomes apparent when the kernel evicts batch buffers which are likely to be written into in the evicted state, and then rebound to the AGP aperture. This means we cannot rely on the AGP module to flush the cache for us.

2006-10-17Add memory usage accounting to avoid DOS problems.Thomas Hellstrom
2006-10-17Remove the memory manager parameter from the put_block function, as thisThomas Hellstrom
makes the client code a lot cleaner. Prepare buffer manager for lock and unlock calls.
2006-10-12Simplify the AGP backend interface somewhat.Thomas Hellstrom
Fix buffer bound caching policy changing, Allow on-the-fly changing of caching policy on bound buffers if the hardware supports it. Allow drivers to use driver-specific AGP memory types for TTM AGP pages. Will make AGP drivers much easier to migrate.
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
2006-10-03Get rid of all ugly PTE hacks.Thomas Hellstrom
2006-10-02Make the user_token 44-bit for TTMs, and have them occupy a unique file spaceThomas Hellstrom
starting at 0x00100000000. This will hopefully allow us to use unmap_mapping_range(). Note that user-space will need 64-bit file offset support.
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
