HuC firmware failing to load for A380

[Widzwill]

Hi - have been trialing 6.5rc1 20230715 o2 gcc 6.12.3 in order to user my A380 for hardware accelerated transcoding. However it seems the HuC firmware fails when loading?

Here is my log of the driver and firmware trying to load -

wondering if this is due to MEI modules missing when the kernel was built? as referenced here https://gitlab.freedesktop.org/drm/intel/-/issues/7732

@Widzwill the solution is some module+.config modifucations mentioned in #12 needs to be done.

I wanted to say forgot to update the firmware files...

[Widzwill]

Well I'm glad that it is just that, I was going mad wondering why it wasn't working 😅

I did try to do my own kernel build and ran into issues

[thor2002ro]

I will probably fix it with rc2 some time this week
