2008-11-13libdrm_intel: fix warnings on 64 bitJesse Barnes
Cast a couple of %llx args to unsigned long long.
2008-11-13libdrm: add support for i915 GTT mapping ioctlJesse Barnes
Add a drm_intel_gem_bo_map_gtt() function for mapping a buffer object through the aperture rather than directly to its CPU cacheable memory.
2008-11-07intel: Restart on interrupt of bo_wait_rendering instead of complaining.Eric Anholt
2008-10-30intel: Rename dri_ and intel_ symbols to drm_intel_.Eric Anholt
I wanted to avoid doing this, as it's a bunch of churn, but there was a conflict between the dri_ symbols in libdrm and the symbols that were in Mesa in 7.2, which broke Mesa 7.2 AIGLX when the 2D driver had loaded new libdrm symbols. The new naming was recommended by cworth for giving the code a unique prefix identifying where the code lives. Additionally, take the opportunity to fix up two API mistakes: emit_reloc's arguments were in a nonsensical order, and set_tiling lacked the stride argument that the kernel will want to use soon. API compatibility with released code is maintained using #defines.
2008-10-28intel: Add dri_bufmgr_check_aperture support for bufmgr_gem.Eric Anholt
This relies on a new kernel ioctl to get the available aperture size. In order to provide reasonable performance from dri_bufmgr_check_aperture, we now require that once a buffer has been used as the target of a relocation, it gets no further relocations added to it. This cuts the cost of check_aperture from 10% to 1% in the 3D driver with no code changes, but slightly complicates our plans for the 2D driver.
2008-10-16intel: ioctl is not defined to return -errnoKeith Packard
Don't count on ioctl returning -errno; use errno directly. Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Eric Anholt <eric@anholt.net>
2008-10-14intel: Add interface for getting tiling mode of a bo.Eric Anholt
2008-10-09intel: Protect bufmgr objects with a pthread mutex.Eric Anholt
We want to be able to use the bufmgr from multiple threads for GL, and thus we need to protect the internal structures. The pthread-stubs package is used so that programs not linked against pthreads get weak symbols to stubs and don't eat most of the cost.
2008-09-23intel: Do strerror on errno, not on the -1 return value from ioctl.Eric Anholt
2008-09-10intel: don't forget to include config.h in bufmgr code.Eric Anholt
Thanks to airlied for catching this.
2008-09-10intel: move drm calls to exec buffers to libdrm_intel.Eric Anholt
This avoids duplicating the effort in 3 places. Also, added emit/wait fence callbacks back in bufmgr_fake since we need it for non-drm 2d. Sigh.
2008-09-10Move intel libdrm stuff to libdrm_intel.soEric Anholt
dri_bufmgr.h is replaced by intel_bufmgr.h, and several functions are renamed, though the structures and many functions remain dri_bufmgr_* and dri_bo_*
2008-08-26[intel_bufmgr_gem] Remember global name when creating buffer from name.Kristian Høgsberg
2008-08-12[intel_bufmgr_gem] Fix flink buffer name caching (#17085, #17092).Kristian Høgsberg
Store the global name in global_name, don't overwrite the gem_handle.
2008-08-08Fix compile warning from check_aperture change.Eric Anholt
2008-08-08Replace the check_aperture API with one we can make thread-safe.Eric Anholt
While the bufmgr isn't thread-safe at the moment, we need it to be for shared objects between contexts.

2008-06-24[intel-gem] Use I915_GEM_DOMAIN_GTT in dri_gem_bo_wait_rendering.Keith Packard
I915_GEM_DOMAIN_CPU is very expensive to wait for -- it generally requires clflushing the frame buffer.
2008-06-20[intel-gem] Add DRM_IOCTL_I915_GEM_SW_FINISH to flag CPU writesKeith Packard
When a software fallback has completed, usermode must notify the kernel so that any scanout buffers can be synchronized. This ioctl should be called whenever a fallback completes to flush CPU and chipset caches.
2008-06-13[gem] Catch -EINTR from blocking ioctls and restart them.Eric Anholt
Thanks to Thomas Hellstrom for catching the issue, no thanks to the kernel developer who authoritatively told me that they would get restarted on their own.
2008-06-11[gem] Move potentially device-specific ioctls to the intel driver.Eric Anholt
This is the create (may want location flags), pread/pwrite/mmap (performance tuning hints), and set_domain (will 32 bits be enough for everyone?) ioctls. Left in the generic set are just flink/open/close. The 2D driver must be updated for this change, and API but not ABI is broken for 3D. The driver version is bumped to mark this.
2008-06-06[gem] Don't forget to munmap in the non-bo-reuse object-freeing case.Eric Anholt
2008-06-06[libdrm/intel] Eliminate extra dri_gem_bo_bucket_entry structureKeith Packard
Place the buffer reuse links right into the dri_bo_gem object.
2008-06-06[libdrm/intel] Remove unused intel_validate_entry structureKeith Packard
2008-06-06[libdrm/intel] Reuse entire dri_bo_gem structureKeith Packard
The code was discarding the dri_bo_gem structure and saving only the kernel handle. This lost the mmap address, causing pain when the next buffer user wanted to map the buffer.
2008-06-03Fix and hook up bufmgr code to the build.Eric Anholt
