I ran into this today:
https://gist.github.com/Brainiarc7/aa43570f512906e882ad6cdd835efe57
DRM firmware is loaded by default. HuC and GuC are not. Things work
without them, and things work with them loaded. So what's the pro/con
and if there's a pro, why isn't it the kernel default? Seems like if
it should be default, either upstream should set them as the default,
or the CPU/GPU should ask for it?
Recently (either 4.10/4.11 kernel, or same time frame Firefox on
F25/F26) I notice a blocky flickering when Firefox is launched. This
doesn't happen with the firmware loaded. So that's nice I guess, but
doesn't seem critical.
Anyway, just curious.
