From e0080cb2001ef3ea05383a22109b83545381a6d2 Mon Sep 17 00:00:00 2001 From: Paul Hsieh Date: Thu, 12 Sep 2024 14:47:51 +0800 Subject: [PATCH] drm/amd/display: Add logs to record register read/write [Why] There are some issues which customer only can provide full dump for analyze, without register history, it's hard to debug HW status. [How] 1. Put register read/write into WPP log so we can trace the logs from full memory dump. 2. MALL doesn't add into WPP, add it.
