Subject: [RFC PATCH 88/97] drm/i915/guc: Support request cancellation
Date: Thu, 6 May 2021 12:14:42 -0700 [thread overview]
Message-ID: <20210506191451.77768-89-matthew.brost@intel.com> (raw)
In-Reply-To: <20210506191451.77768-1-matthew.brost@intel.com>
This adds GuC backend support for i915_request_cancel(), which in turn
makes CONFIG_DRM_I915_REQUEST_TIMEOUT work.
