If anyone has any objections, please let me know. ------------------ From: Marcin Bernatowicz [ Upstream commit d1643db3b037b57f2af7f85c3821d6fe69c492f6 ] VFs were missing the call to apply the global scheduling policy. Call xe_guc_submit_enable() during vf_uc_load_hw() to ensure VFs get the same policy enforcement as PF.
