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 seem to remember seeing previous feedback that Bhyve developers
strongly preferred the BhyveFwCtl mechanism. I've been out of the loop
though (busy with $dayjob) so I don't know if things have changed.
Hopefully other people can provide feedback.

I seem to remember seeing previous feedback that Bhyve developers
strongly preferred the BhyveFwCtl mechanism. I've been out of the loop

Hi Peter and Rebecca, thanks for your feedback. This patch is backward compatible. It checks if QemuFwCfg is available and if QemuFwCfg is missing it falls back to BhyveFwCtl. So, should I add Reviewed-by (or Acked-by?) Peter and Rebecca to the commit message? Thanks Corvin Beckhoff Automation GmbH & Co. KG | Managing Director: Dipl. Phys.

I've just looked at the patch and it looks good, though I haven't tested it.

im trying to test the patch on my pc,that has two graphic cards,the intel coffee lake and the nvidia. i tried to start the pc from the nvidia card and ive configured the xorg.conf file giving the proper bus id value. in addition ive loaded the kernel.ko file from the boot loader.conf i have removed the intel and the drm drivers used by the Intel graphic card. unfortunately my pc wont boot from the nvidia card. my mouse and keyboard freezes just before the desktop manager (xfce and kde5) starts.

Is this a laptop? Things may not work there because video output is done through the Intel GPU, even when using the Nvidia GPU, although I'm not sure.
