| Subject: [PATCH 3/3] Partially revert "[VP] Fix aux mapping issue" |
| |
| This partially reverts commit df5c37ee919a4305f09203bf1bca4bd65a653c94 by |
| restoring the change associated with the setting of WaAuxTable16KGranular |
| in media_driver/linux/gen12/ddi/media_sysinfo_g12.cpp. |
| |
| This is a temporary workaround for addressing a video hardware decoding |
| regression observed on Chrome OS on Gen12. |
