2008-10-09Manage fences in user-mode bufmgr_fake to clean buffersKeith Packard
When using bufmgr_fake without DRM, the X server idles the ring whenever it wants to wait for something to complete (brutal, but effective). In this case, bufmgr_fake must treat the pending fence as having passed. However, it wasn't recording the fences as it emitted them, nor cleaning buffers as they passed.

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: Allow up to 15 seconds chewing on one buffer before acknowledging -EBUSY.Eric Anholt
The gltestperf demo in some cases took over seven seconds to make it through one batchbuffer on a GM965. Bug #17004.
2008-09-23intel: Replace wraparound test logic in bufmgr_fake. Again.Eric Anholt
I'd swapped the operands, so if we weren't in lockstep with the hardware we said the sequence was always passed. Additionally, a race was available that we might have failed at recovering from. Instead, I've replaced the logic with new stuff that should be more robust and not rely on all the parties in userland following the same IRQ_EMIT() == 1 protocol. Also, in a radical departure from past efforts, include a long comment describing the failure modes and how we're working around them. Thanks to haihao for catching the original issue.

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.
2008-09-10intel: Move IRQ emit/wait from callbacks into the bufmgr.Eric Anholt
In the process, work around the glaring bugs of the kernel irq wait function.
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_*

Store the global name in global_name, don't overwrite the gem_handle.

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.
2008-06-11Move the renaming of mm.c symbols to #defines in the header.Eric Anholt
This reduces the diff from Mesa and reduces the illegibility of what I did.
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[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.
2008-06-05Add a function to bufmgr_fake to evict all buffers in the GTT.Eric Anholt
This will be used by the X Server for VT switch.
