linux-toradex.git/drivers/gpu/drm/radeon/rs780d.h, branch v4.15 Linux kernel for Apalis and Colibri modules drm/radeon/dpm: add debugfs support for RS780/RS880 (v3) 2013-07-17T20:47:52+00:00 Alex Deucher alexander.deucher@amd.com 2013-07-02T17:05:23+00:00 444bddc4b9b3313a562cd3ba40f780fb82570f7d This allows you to look at the current DPM state via debugfs. Due to the way the hardware works on these asics, there's no way to look up exactly what power state we are in, so we make the best guess we can based on the current sclk. v2: Anthoine's version v3: fix ref div Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
