[GPU passthru] how to handle Extension ROM properly
Posted: Sat Apr 11, 2020 2:01 pm
Hello,
I'm trying to implement a proper GPU(nvidia) passthru to have most of its features working correctly in VM(bhyve).
Right now all the BARs + ROM BAR are mapped to proper MMIO windows in RAM, but there is something still missing and I'd like to figure it out.
Do we have some materials or existing implementations to study? Any help is welcome.
