From b97060a99b01b4d706b87df450b69f82962d2fba Mon Sep 17 00:00:00 2001 From: Matthew Brost Date: Wed, 21 Jul 2021 14:50:58 -0700 Subject: drm/i915/guc: Update intel_gt_wait_for_idle to work with GuC When running the GuC the GPU can't be considered idle if the GuC still has contexts pinned. As such, a call has been added in intel_gt_wait_for_idle to idle the UC and in turn the GuC by waiting for the number of unpinned contexts to go to zero. v2: rtimeout -> remaining_timeout v3: Drop unnecessary includes, guc_submission_busy_loop -> guc_submission_send_busy_loop, drop negatie timeout trick, move a refactor of guc_context_unpin to earlier path (John H) v4: Add stddef.h back into intel_gt_requests.h, sort circuit idle function if not in GuC submission mode Cc: John Harrison Signed-off-by: Matthew Brost Reviewed-by: John Harrison Signed-off-by: John Harrison Link: https://patchwork.freedesktop.org/patch/msgid/20210721215101.139794-16-matthew.brost@intel.com --- drivers/gpu/drm/i915/gt/uc/intel_guc_ct.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'drivers/gpu/drm/i915/gt/uc/intel_guc_ct.h') diff --git a/drivers/gpu/drm/i915/gt/uc/intel_guc_ct.h b/drivers/gpu/drm/i915/gt/uc/intel_guc_ct.h index dda2d6a75392..2758ee849a59 100644 --- a/drivers/gpu/drm/i915/gt/uc/intel_guc_ct.h +++ b/drivers/gpu/drm/i915/gt/uc/intel_guc_ct.h @@ -10,6 +10,7 @@ #include #include #include +#include #include "intel_guc_fwif.h" @@ -68,6 +69,9 @@ struct intel_guc_ct { struct tasklet_struct receive_tasklet; + /** @wq: wait queue for g2h chanenl */ + wait_queue_head_t wq; + struct { u16 last_fence; /* last fence used to send request */ -- cgit v1.2.3
