From 1523742d4c23b3d31aac4a17b6bac7c19c8bd3b9 Mon Sep 17 00:00:00 2001 From: Tim Wawrzynczak Date: Wed, 27 Jul 2022 09:56:41 -0600 Subject: mb/google/brya/var/agah: Update ASPM settings for dGPU After some debugging, it has been determined that the ASPM L0s substate is functional, but there is still some problem with ASPM L1 substates, so this patch updates ASPM status for the dGPU from disabled to L0s only.
