i915_wait_request() only checks mm.wedged after it interacts with the hardware, generally causing the driver to lock up waiting for a wedged chip. Make sure we check mm.wedged as the first thing we do. Signed-off-by: Ben Gamari <bgamari.foss@gmail.com> --- drivers/gpu/drm/i915/i915_gem.c | 3 +++ 1 files changed, 3 insertions(+), 0 deletions(-)
