Subject: [PATCH v2 3/4] drm/xe: Extract xe_gt_idle() helper
Date: Mon, 22 Apr 2024 12:27:55 +0530 [thread overview]
Message-ID: <20240422065756.294679-4-aravind.iddamsetty@linux.intel.com> (raw)
In-Reply-To: <20240422065756.294679-1-aravind.iddamsetty@linux.intel.com>
This would be used in other places outside of gt_reset path.
v2:
1. Add kernel doc for xe_gt_idle (Michal)
2. fix return as no actual error is reported by xe_uc_stop (Himal)
