From 6335e1d28c422050024bcf4100c4fb3a5bac2afb Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Mon, 10 Sep 2012 14:15:02 +0300 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. v2: Update based on Mika's kernel work. v3: Fix compile failures from last-minute typos. Sigh.
