Thomas Hellstrom 94c22c3349 User buffer support. 2007-11-02 16:05:25 +01:00
Dave Airlie 61cbcb5dbe drm/ttm: add support for cached un-snooped mappings.
This mapping allows cached objects to be mapped in/out of the TT space
with the appropriate flushing calls.

It should put back the old CACHED functionality for snooped mappings

Thomas Hellstrom 53aee3122a I915 accelerated blit copy functional.
Fixed - to System memory copies are implemented by
flipping in a cache-coherent TTM,
blitting to it, and then flipping it out.

Thomas Hellstrom 3b8e6ccd25 Security fix. Zero pages before they are handed to user space.
TTM pages were not cleared when allocated and handed to user space.
Sensitive information may leak.

Thomas Hellstrom 4b04c0cc45 Bugzilla Bug #8819
Build fixes for powerpc.

2006-10-30 11:18:44 +01:00
Thomas Hellstrom b4fba1679b Add a one-page hole in the file offset space between buffers. 2006-10-26 21:14:23 +02:00
Thomas Hellstrom 9ed4656799 The CPU cache must be flushed _before_ we start modifying the kernel map ptes,
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.

Thomas Hellstrom d515936ea7 Add memory usage accounting to avoid DOS problems. 2006-10-17 19:40:57 +02:00
Thomas Hellstrom db5c671e86 Remove the memory manager parameter from the put_block function, as this
makes the client code a lot cleaner. Prepare buffer manager for lock and
unlock calls.
2006-10-17 11:28:48 +02:00
Thomas Hellstrom 10150df02b Simplify the AGP backend interface somewhat.
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.

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 cee659afb5 Get rid of all ugly PTE hacks. 2006-10-03 12:08:07 +02:00
Thomas Hellstrom eacedf41a6 Make the user_token 44-bit for TTMs, and have them occupy a unique file space
starting at 0x00100000000. This will hopefully allow us to use
unmap_mapping_range(). Note that user-space will need
64-bit file offset support.
