--- Comment #18 from Kertesz Laszlo laszlo.kertesz@gmail.com --- Tested with 3.12.0-next-20131111, started the computer and launched Steam and TF2 right away.
Activating enable_nbps_policy to enable_gfx_clock_gating worked well.
The enable_mg_clock_gating, enable_gfx_dynamic_mgpg, override_dynamic_mgpg options gave gpu lockups and softresets (same as the above attachment), mostly after i entered the map, but sometimes after the reset the game was resumed and could play without issues. Combining them with uvd_dpm seems to be the killer factor though.
This is what seems to work well so far (uvd_dpm seems to not create problems if the mgpg and mg options are disabled:
pi->enable_bapm = false; pi->enable_nbps_policy = true; /*mychange*/ pi->enable_sclk_ds = true; pi->enable_gfx_power_gating = true; pi->enable_gfx_clock_gating = true; pi->enable_mg_clock_gating = false; pi->enable_gfx_dynamic_mgpg = false; /* ??? */ pi->override_dynamic_mgpg = false; pi->enable_auto_thermal_throttling = true; pi->voltage_drop_in_dce = false; /* need to restructure dpm/modeset interaction */ pi->uvd_dpm = true; /* ??? */
