Subject: [PATCH i-g-t v1 2/7] tools/vbt_decode: vary number of rows wrt VBT #57
Date: Thu,  7 May 2026 03:28:16 +0200	[thread overview]
Message-ID: <20260507012821.527453-3-michal.grzelak@intel.com> (raw)
In-Reply-To: <20260507012821.527453-1-michal.grzelak@intel.com>

Current implementation assumes that each VBT #57 table contains 10
rows. That is true for pre-MTL platforms. However, GOP for MTL+ actually
contains 16 rows. Show the number of rows during dumping.
