Not enough MMIO resources for SR-IOV

[vinipsmaker]

So as I understand my motherboard (Gigabyte Vision B550 D-P) doesn’t allocate enough resources for my SR-IOV device (a S7150). However they still release BIOS updates. I was wondering on the best way to approach the Gigabyte support on asking them to release a new BIOS.

make sure you have done the following
disable CSM
Enable above 4G decoding
Enable Resizable bar/Smart access memory

[vinipsmaker]

Above 4G decoding and resizble bar were already enabled. I’ll look for CSM settings.

[GigaBusterEXE]

I’m no expert but to my knowlege mmio had something to do with barspace, been a while since I last looked it up, might be unrelated

Okay those were the settings there already. Unfortunately I’ve got a new error now:

I’ll need to look for a VBIOS for my S7150 and I’ll be unable to really test the motherboard BIOS in the meantime (at least as it concerns to SR-IOV).
