This seems bad to me. I honestly can't reconcile your comment with the code&patch. Afaics - the pll disable code checks for the pipe a quirk and does an early exit before mucking around with the hw and calling assert_pipe. - assert_pipe only does a WARN and the patch only changes whether we hit that WARN. All reg reads/writes should be unchanged. - the backtrace I'm seeing goes through crtc_disable. Yours, Daniel -- Daniel Vetter Mail: daniel at ffwll.ch Mobile: +41 (0)79 365 57 48
