>Subject: [PATCH v2 2/3] drm/i915/guc: Change default GuC FW for BXT to v9.29
>
>This patch makes v9.29 firmware as default firmware for BXT.
>
>Note: GuC logging control is changed with this firmware. GuC is expecting i915 to
>set control bit to enable "default logging"
>while using GuC action UK_LOG_ENABLE_LOGGING.
>However i915 is currently not doing this because it is version specific change and
>can be handled entirely in GuC. It will need to be fixed in future firmwares.
>
>This update includes (since v8.7):
>
>- Added support to log media reset count for host to read it
>- BXT WA for fixing MTP hangs. WaDisableDOPRenderClkGatingAtSubmit
