From ba7b267a458e133cbd791c818fb4cb41180242c6 Mon Sep 17 00:00:00 2001 From: Fatemeh Darbehani Date: Fri, 5 Oct 2018 17:22:32 -0400 Subject: [PATCH] drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h - part4 [Why] In DCN we want direct DC to SMU calls, with minimal interference from pplib. The reason for each pp_smu interface mapping to 1 SMU message is so we can have the sequencing of different SMU message in DC and shared across different OS's. This will also simplify debugging as DAL owns this interaction and there's no confusion about division of ownership. [How] Part 4: Change clock units so they match the values PPLib sends to SMU.
