  0 days since I did sudo service gdm stop on the wrong machine.

  it was all bit 1 of NV_VIRTUAL_FUNCTION_PRIV_MMU_INVALIDATE_PDB fault. nouveau on spark runs some tests now.

  I need a "Do not use debian stable for GPU development" sign to tap on.

  sometimes it's easier to just add new printks than to work out how to switch on the pre-existing ones that are buried in driver macros and dynamic debug.

  deviceName = NVK GB20B though CTS is a failfest due to some sync or coherency issue, and display isn't working yet.
