[PATCH v2 1/1] drm/xe/xe2: Send flat_ccs value in struct drm_xe_query_config

Tue Mar 26 10:10:31 UTC 2024


Currently, we don't have any check in IGT testcases if platform supports
compression or not. Send this flat_ccs value as part of the struct
drm_xe_query_config so that we can read this value in the igt testcases
and proceed accordingly.
Fixes: VLK-56136
