In some cases this is not fatal error as driver will retry. Convert the log to a trace log for debugging without triggering unnecessary concerns in CI or for end-users during non-fatal scenarios. v2: Improve commit message(Tvrtko) Cc: Tvrtko Ursulin Cc: John Harrison Cc: Andi Shyti Cc: Andrzej Hajda Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/5591 Signed-off-by: Nirmoy Das Reviewed-by: Andi Shyti Reviewed-by: Andrzej Hajda --- drivers/gpu/drm/i915/gt/intel_reset.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/i915/gt/intel_reset.c b/drivers/gpu/drm/i915/gt/intel_reset.c index d5ed904f355d..e6fbc6202c80 100644 --- a/drivers/gpu/drm/i915/gt/intel_reset.c +++ b/drivers/gpu/drm/i915/gt/intel_reset.c @@ -593,10 +593,10 @@ static int gen8_engine_reset_prepare(struct intel_engine_cs *engine) ret = __intel_wait_for_register_fw(uncore, reg, mask, ack, 700, 0, NULL); if (ret) - gt_err(engine->gt, - "%s reset request timed out: {request: %08x, RESET_CTL: %08x}\n", - engine->name, request, - intel_uncore_read_fw(uncore, reg)); + GT_TRACE(engine->gt, + "%s reset request timed out: {request: %08x, RESET_CTL: %08x}\n", + engine->name, request, + intel_uncore_read_fw(uncore, reg)); return ret; }
