2006-12-19Security fix. Zero pages before they are handed to user space.Thomas Hellstrom
Shared memory areas were not cleared when they are allocated and handed to user space. Sensitive information may leak.
2006-12-19Reclaim buffers locked fixup.Thomas Hellstrom
Avoid calling reclaim_buffers_locked if we don't have a hardware lock. Improve reclaim_buffers_locked deadlock error formatting.

2006-12-19Revert "drm: ioremap balanced with iounmap for drivers/char/drm"Dave Airlie
This reverts cc22cd8bde39f3e4be8ca9f726a773b0270ebdbc commit. I put this patch incorrectly in .. will fix now
2006-12-19drm: ioremap balanced with iounmap for drivers/char/drmDave Airlie
ioremap must be balanced by an iounmap and failing to do so can result in a memory leak. Tested (compilation only) to make sure the files are compiling without any warning/error due to new changes Signed-off-by: Amol Lad <amol@verismonetworks.com> Signed-off-by: Dave Airlie <airlied@linux.ie>
2006-12-16drm/linux-core: drmP.h compilation fixMichael Buesch
I need the following patch to fix compilation of latest drm/linux-core on my ppc64 machine. /home/mb/develop/git/drm/linux-core/savage_bci.c: In function ‘savage_driver_firstopen’: /home/mb/develop/git/drm/linux-core/savage_bci.c:587: error: ‘DRM_MTRR_WC’ undeclared (first use in this function) /home/mb/develop/git/drm/linux-core/savage_bci.c:587: error: (Each undeclared identifier is reported only once /home/mb/develop/git/drm/linux-core/savage_bci.c:587: error: for each function it appears in.) /home/mb/develop/git/drm/linux-core/savage_bci.c: In function ‘savage_driver_lastclose’: /home/mb/develop/git/drm/linux-core/savage_bci.c:664: error: ‘DRM_MTRR_WC’ undeclared (first use in this function) I looked at in-kernel drmP.h and it actually has the same fix in it.

2006-12-15Remove the memory caches for fence objects and memory manager nodes,Thomas Hellstrom
since the support for memory caches has gone from 2.6.20.
2006-12-01Unshare drm_drawable.c again for now.Michel Dänzer
The current version didn't build on BSD, where the new functionality isn't used yet anyway. Whoever changes that will hopefully be able to make the OSes share this file as well.
2006-12-01Track linux-core symlinks in git.Michel Dänzer
2006-10-30Bugzilla Bug #8819Thomas Hellstrom
Build fixes for powerpc. Reported by Katerina Barone-Adesi
2006-10-27Last minute changes to support multi-page size buffer offset alignments.Thomas Hellstrom
This will come in very handy for tiled buffers on intel hardware. Also add some padding to interface structures to allow future binary backwards compatible changes.
2006-10-26New mm function names. Update header.Thomas Hellstrom
2006-10-26Add improved alignment functionality to the core memory manager.Thomas Hellstrom
This makes an allocated block actually align itself and returns any wasted space to the manager. Also add some functions to grow and shrink the managed area. This will be used in the future to manage the buffer object swap cache.
2006-10-26Add a one-page hole in the file offset space between buffers.Thomas Hellstrom
2006-10-21Merge branch 'master' of git+ssh://git.freedesktop.org/git/mesa/drmThomas 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.
2006-10-20Bug #1746: Set dev_priv_size for the MGA driver.Tilman Sauerbeck
2006-10-20We apparently need this global cache flush anyway.Thomas Hellstrom

2006-10-19Make sure delayed delete list is empty on lastclose.Thomas Hellstrom
Fix some refcounting errors. Fix some error messages.

2006-10-18Remove stray softlink.Thomas Hellstrom
2006-10-18Avoid driver-specific AGP user-populated types, since we don't know what AGPThomas Hellstrom
driver we're on. Avoid global cache flushes before inserting pages. In general, they are never mapped, and not accessed through the kernel map, so a cache flush should not be necessary. The exception is pages that are bound cached. We might need a cache flush for those.
2006-10-17Remove max number of locked pages check and call, sinceThomas Hellstrom
that is now handled by the memory accounting.
2006-10-17Lindent.Thomas Hellstrom
2006-10-17Add vma list memory usage to memory accounting.Thomas Hellstrom
Use byte unit for /proc printout of memory usage for small sizes to be able to detect memory allocation bugs more easily.
2006-10-17Add memory usage accounting to avoid DOS problems.Thomas Hellstrom
2006-10-17Implement mm_lock and mm_unlock functions.Thomas Hellstrom
The mm_lock function is used when leaving vt. It evicts _all_ buffers. Buffers with the DRM_BO_NO_MOVE attribute set will be guaranteed to get the same offset when / if they are rebound.
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.
2006-10-17Extend generality for more memory types.Thomas Hellstrom
Fix up init and destruction code.
2006-10-16Change Intel AGP memory type numbers.Thomas Hellstrom
2006-10-14remove config.h from build no longer exists kbuild does itDave Airlie
2006-10-12Bugfixes.Thomas Hellstrom
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
