i915 and acrngt as modules


Ross Burton <ross.burton@...>
 

Hi,

I'm debugging a problem where graphics output doesn't work if i915 is
built as a kernel module instead of built in. If i915.enable_gvt The
problem is that acrngt isn't pulled in first:

[ 8.307364] acrngt not found

This results in i915 not starting correctly, and no output.

I'm solving that right now with a modprobe.d/acrn.conf file:

softdep i915 pre: acrngt

So that acrngt is loaded before i915, but I can't help but think this
is something i915 should be doing already. Is my modprobe tweak
really the best way, or can the kernel drivers themselves ask to load
that module themselves?

Cheers,
Ross
