--- Comment #37 from Pierre Moreau <pierre.morrow-GANU6spQydw@public.gmane.org> ---
To extract the VBIOS, look at
https://nouveau.freedesktop.org/wiki/DumpingVideoBios/, trying either of both
last options (nvagetbios or cat vbios.rom).

Regarding the MMIOtrace, I should have been more specific, sorry. I am looking
for a MMIOtrace of the blob being loaded with no external screen:

1. start the trace
2. modprobe nvidia
3. start X
4. `echo 'Plugging screen' > /sys/kernel/debug/tracing/trace_marker`
5. plug the screen and set it up to get an image
6. `echo 'Screen is ready' > /sys/kernel/debug/tracing/trace_marker`
7. stop the trace

and a similar one where the screen is already plugged in during the boot:


1. start the trace
2. modprobe nvidia
3. start X
#if is_needed
4. `echo 'Setting up screen' > /sys/kernel/debug/tracing/trace_marker`
5. set it up to get an image
6. `echo 'Screen is ready' > /sys/kernel/debug/tracing/trace_marker`
#endif
7. stop the trace
