From e7696d652102dd5ac2681d69da2004925d6a6b30 Mon Sep 17 00:00:00 2001 From: John Harrison Date: Thu, 26 Jan 2023 16:28:39 -0800 Subject: [PATCH] drm/i915: Allow error capture of a pending request A hang situation has been observed where the only requests on the context were either completed or not yet started according to the breaadcrumbs. However, the register state claimed a batch was (maybe) in progress. So, allow capture of the pending request on the grounds that this might be better than nothing. v2: Reword 'not started' warning message (Tvrtko) Signed-off-by: John Harrison Reviewed-by: Tvrtko Ursulin Link: https://patchwork.freedesktop.org/patch/msgid/20230127002842.3169194-6-John.C.Harrison@Intel.com --- drivers/gpu/drm/i915/i915_gpu_error.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_gpu_error.c b/drivers/gpu/drm/i915/i915_gpu_error.c index 225f1b11a6b93..904f21e1380cd 100644 --- a/drivers/gpu/drm/i915/i915_gpu_error.c +++ b/drivers/gpu/drm/i915/i915_gpu_error.c @@ -1624,12 +1624,9 @@ capture_engine(struct intel_engine_cs *engine, return NULL; intel_engine_get_hung_entity(engine, &ce, &rq); - if (rq && !i915_request_started(rq)) { + if (rq && !i915_request_started(rq)) drm_info(&engine->gt->i915->drm, "Got hung context on %s with active request %lld:%lld [0x%04X] not yet started\n", engine->name, rq->fence.context, rq->fence.seqno, ce->guc_id.id); - i915_request_put(rq); - rq = NULL; - } if (rq) { capture = intel_engine_coredump_add_request(ee, rq, ATOMIC_MAYFAIL); -- 2.30.2
