2013-11-26 intel: Track known prime buffers for re-useKeith Packard
If the application sends us a file descriptor pointing at a prime buffer that we've already got, we have to re-use the same bo_gem structure or chaos will result. Track the set of all known prime objects and look to see if the kernel has returned one of those for a new file descriptor. Also checks for prime buffers in the flink case.

2013-11-15intel: Add support for GPU reset status query ioctlIan Romanick
I would have just used the drmIoctl interface directly in Mesa, but the ioctl needs some data from the drm_intel_context that is not exposed outside libdrm. This ioctl is in the drm-intel-next tree as b635991. v2: Update based on Mika's kernel work. v3: Fix compile failures from last-minute typos. Sigh. v4: Import the actual changes from the kernel i915_drm.h. Only comments on some fields of drm_i915_reset_stats differed. There are still some deltas between the kernel i915_drm.h and the one in libdrm, but those can be resolved in other patches.

2012-07-12intel: Change context create failure message to from fprintf to DBG().Kenneth Graunke
Since there is no getparam for hardware context support, Mesa always tries to obtain a context by calling drm_intel_gem_context_create and NULL-checking the result. On an older kernel without context support, this caused libdrm to print an unwanted message to stderr: DRM_IOCTL_I915_GEM_CONTEXT_CREATE failed: Invalid argument In fact, this caused every Piglit test to fail with a "warn" status due to the unrecognized error message. Change the message to use DBG() rather than fprintf(), so people can still get the debug message, but it won't spam normally.

2012-05-10intel: Add the ability to supply annotations for .aub files.Paul Berry
This patch adds a new function, drm_intel_bufmgr_gem_set_aub_annotations(), which can be used to annotate the type and subtype of data stored in various sections of each buffer. This data is used to populate type and subtype fields when generating the .aub file, which improves the ability of later debugging tools to analyze the contents of the .aub file. If drm_intel_bufmgr_gem_set_aub_annotations() is not called, then we fall back to the old set of annotations (annotate the portion of the batchbuffer that is executed as AUB_TRACE_TYPE_BATCH, and everything else as AUB_TRACE_TYPE_NOTYPE).
