What exactly is the problem? We never use idle frequency while active, always restarting at max(cur, rpe). So for the simple minded among us, where is the igt demonstrating the issue? -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
