Subject: [igt-dev] [PATCH i-g-t 2/3] tools/intel_vbt_decode: add --header option to only print header
Date: Tue, 23 Jan 2018 12:54:31 +0200	[thread overview]
Message-ID: <20180123105432.15094-2-jani.nikula@intel.com> (raw)
In-Reply-To: <20180123105432.15094-1-jani.nikula@intel.com>

Sometimes it's useful just to print the VBT and BDB headers.
