GuC supports different scheduling policies for its four internal queues. Currently these have been set to the same default values as KMD_NORMAL queue. Particularly POLICY_MAX_NUM_WI is set to 15 to match GuC internal maximum submit queue numbers to avoid an out-of-space problem. This value indicates max number of work items allowed to be queued for one DPC process. A smaller value will let GuC schedule more frequently while a larger number may increase chances to optimize cmds (such as collapse cmds from same lrc) with risks that keeps CS idle. v1: tidy up code Signed-off-by: Alex Dai <yu.dai@intel.com> Reviewed-by: Dave Gordon <david.s.gordon@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1450468812-4882-4-git-send-email-yu.dai@intel.com Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |
