Hmm. The firmware may change between the hang and cat
/sys/class/drm/card0/error (as it will be reloaded after the reset).
Btw, maybe we should add counter that will be incremented on each fw reload
and reported here ?
If it occurs to you that we need it for post-mortem debugging and having
it is worth more than any potential confusion....
I can see the need for knowing what guc/huc/dmc/etc was running at the
time of a hang - I just hope that what was previously running before an
earlier reset doesn't contribute. But that's why we focus on the first
error in a system...
Can the firmware change?
Last time I checked the filename was hard-coded in the driver. It's true
that the load process could fail and then the information be incorrect.
