From 5a41b025042c42788977e67aea8d1bf3b59baae4 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Fri, 15 Nov 2013 10:24:43 -0800 Subject: intel: Add support for GPU reset status query ioctl 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.
