2007-02-08A minor function interface change and some memcpy bugfixing.Thomas Hellstrom
Hooray!! it sort of works with a fixed AGP area as faked VRAM.
2007-02-08Simplify external ttm page allocation.Thomas Hellstrom
Implement a memcpy fallback for copying between buffers.
2007-02-06Simplify pci map vs no pci map choice.Thomas Hellstrom
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.
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.
2006-10-20Bug #8707, 2.6.19-rc compatibility for memory manager code.Thomas Hellstrom
2006-10-17Remove max number of locked pages check and call, sinceThomas Hellstrom
that is now handled by the memory accounting.
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
2006-10-03Get rid of all ugly PTE hacks.Thomas Hellstrom
2006-09-27Adapt to architecture-specific hooks for gatt pages.Thomas Hellstrom
2006-09-18Alternative implementation of page table zeroing using zap page_range.Thomas Hellstrom
(Disabled for now) Fix bo_wait_idle bug. Remove stray debug message.
2006-09-14Remove the use of reserved pages, and use locked pages instead.Thomas Hellstrom
Update compatibility for latest linux versions.
2006-09-08Various bugfixes.Thomas Hellstrom
2006-08-25Module protection map access is moving into mainline kernels.Thomas Hellstrom
Update drm_compat accordingly. (Reported by Dave Airlie)
2006-08-21Backwards compatibility code for ttms.Thomas Hellstrom
