Subject: drm/amd/powerplay: implement sysfs of pp_force_state for sw-smu
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0b53f9add0d8dbd3c8d44f78c0d847fcc1251883;p=openwrt%2Fstaging%2Fblogic.git

drm/amd/powerplay: implement sysfs of pp_force_state for sw-smu

the SMU v11 doesn’t support pp_force_state so far, so we didn’t implement
it.
