From: Likun Gao Date: Thu, 20 Dec 2018 12:31:55 +0000 (+0800) Subject: drm/amd/powerplay: set defalut dpm table for smu X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d6a4aa825a65ee7ec0293666fd1572e4621ad13d;p=openwrt%2Fstaging%2Fblogic.git drm/amd/powerplay: set defalut dpm table for smu Add smu_set_default_dpm_table function to set dpm table for smu11. Modified the sequence to populate smc pptable, as it should be done after related dpm feature is enabled.
