It re-clocks memory (for single head anyway), r600_set_power_state():
/* set memory clock */
if (rdev->asic->set_memory_clock && (mclk !=
rdev->pm.current_mclk)) {
radeon_sync_with_vblank(rdev);
radeon_pm_debug_check_in_vbl(rdev, false);
radeon_set_memory_clock(rdev, mclk);
radeon_pm_debug_check_in_vbl(rdev, true);
rdev->pm.current_mclk = mclk;
DRM_INFO("Setting: m: %d\n", mclk);
}
The simd stuff is still disabled at the moment.
> Otherwise it seems to work fine.
Thanks for testing.
