[edk2-devel] [PATCH v6] OvmfPkg/Bhyve: add support for QemuFwCfg
Posted by Corvin Köhne 2 years ago 
QemuFwCfg is much more powerful than BhyveFwCtl. Sadly, BhyveFwCtl
decided to use the same IO ports as QemuFwCfg. It's not possible to use
both interfaces simultaneously. So, prefer QemuFwCfg over BhyveFwCtl.

I tried to merge this but it is rejected by CI, and I got lost in the
maze of CI status and report pages. Could someone please figure out
what's wrong?

The Standard_Error_Output.log file isn't even really useful (it should 
show a diff), but there's something wrong with the coding style in Bhyve.c:
