Benjamin, could you do a test for us (with my custom kernel build) ?

We want to determine what happens when this option is enabled but the firmware cannot be found. I tried to determine it from the source-code but there are so many levels of indirection it will be easier to simply test.

The firmware for TU117 GSP is sym-linked to the TU116, that is in turn sym-linked to TU102 files. So, to *temporarily, for this test only* prevent that firmware being found do:

  $ sudo mv /usr/lib/firmware/nvidia/tu102/gsp/gsp-535.113.01.bin{,.disabled}

Then check the tu117 sym-link is now broken:

  $ realpath -e /usr/lib/firmware/nvidia/tu117/gsp/gsp-535.113.01.bin
  realpath: /usr/lib/firmware/nvidia/tu117/gsp/gsp-535.113.01.bin: No such file or directory

Reboot and share the kernel log. I'm hoping it falls back to the VBIOSInit routine and you see the same messages we saw originally, with those "table '*' not found" messages.

To reinstate the firmware file do:

  $ sudo mv /usr/lib/firmware/nvidia/tu102/gsp/gsp-535.113.01.bin{.disabled,}
  $ realpath -e /usr/lib/firmware/nvidia/tu117/gsp/gsp-535.113.01.bin
  /usr/lib/firmware/nvidia/tu102/gsp/gsp-535.113.01.bin
