Subject: [PATCH v2 11/13] drm/i915/guc: Default to non-verbose GuC logging
Date: Mon, 19 Mar 2018 10:53:46 +0100	[thread overview]
Message-ID: <20180319095348.9716-11-michal.winiarski@intel.com> (raw)
In-Reply-To: <20180319095348.9716-1-michal.winiarski@intel.com>

Now that we've decoupled logging from relay, GuC log level is only
controlling the GuC behavior - there shouldn't be any impact on i915
behaviour. We're only going to see a single extra interrupt when log
will get half full.
That, and the fact that we're seeing igt/gem_exec_nop/basic-series
failing with non-verbose logging being disabled.

v2: Bring back the "auto" guc_log_level, now that we fixed the log
