Subject: [PATCH i-g-t v7 1/4] lib/intel_pat: Support other than gt0 during parsing debugfs PAT
Date: Wed, 1 Apr 2026 15:53:45 +0200 [thread overview]
Message-ID: <20260401135343.2874239-7-zbigniew.kempczynski@intel.com> (raw)
In-Reply-To: <20260401135343.2874239-6-zbigniew.kempczynski@intel.com>
Main and media GTs may define different PTA entries so add gt as an
argument during debugfs pat config selection.
