Browse source

Support dynamic priority change for multi queue group queues via
exec queue set_property ioctl. Issue CGP_SYNC command to GuC through
the drm scheduler message interface for priority to take effect.

v2: Move is_multi_queue check to exec_queue layer and assert
    is_multi_queue being set in guc submission layer (Matt Brost)
v3: Assert CGP_SYNC message length is valid (Matt Brost)
