From 773d8bb5ba7f64ee708caecb8deb0930bc1e1cf7 Mon Sep 17 00:00:00 2001 From: Lili Li Date: Fri, 4 Jul 2025 23:16:08 +0800 Subject: [PATCH] EDAC/igen6: Add Intel Wildcat Lake SoCs support Intel Wildcat Lake is a mobile derivative of Panther Lake with one memory controller. Wildcat Lake SoCs share the same IBECC registers with Meteor Lake-P SoCs. Add a compute die ID and a new configuration structure for Wildcat Lake SoCs with In-Band ECC capability for EDAC support.
