From b2225568cc7bbffc6fa4c65cdd83e2de2eacb84b Mon Sep 17 00:00:00 2001 From: Stylon Wang Date: Fri, 30 Jun 2023 16:48:23 +0800 Subject: [PATCH] drm/amdgpu: Add dcdebugmask option to enable DPIA trace [Why & How] It's useful to be able to enable DPIA trace with dcdebugmask option, especially to debug DPIA issues involved in transition of system power states. This patch adds an option to amdgpu.dcdebugmask to be picked up by amdgpu DM to enable DPIA trace.
