This is backwards. The rps worker should not be running when the device is idle. The code tries to do that currently but fails, so I think this as papering over the bug. Fixing this means we can remove the DISABLE_RPM_WAKEREF_ASSERTS. The patch I've previously sent does https://cgit.freedesktop.org/~ickle/linux-2.6/commit/?h=tasklet&id=1c0ace26e80188e53a18977e5ef90ab8a801027c -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
