From 3dc9427becb4278c7f205ca7494bbb957dbcbde5 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Mon, 9 Feb 2026 13:32:53 +0530 Subject: [PATCH] soc/intel/pantherlake: Update IGD stolen memory size MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit increases the default pre-allocated IGD stolen memory size from 64MB to 128MB in FSP-M parameters. This ensures sufficient memory is allocated for higher resolution displays and graphics-intensive early-boot tasks on Panther Lake platforms. BUG=b:481209815 TEST=Able to build and boot google/ruby.
