[edk2-devel] [PATCH v2] OvmfPkg: Use DxeRuntimeCapsuleLib from DxeCapsuleLibFmp in X64 builds

[Tomas Pilar (tpilar)]

I mean you need a PCI device with a UEFI driver that implements FMP to test this. Our Solarflare driver currently does, so I can test this, I've sent two of our NICs to Peter Jones @ RedHat (If you are interested, I can get you a sample of our adapter along with drivers).

Once you have your PCI device and a driver, you make a capsule using GenerateCapsule, adding the driver alongside your payload. 

With newish qemu and ovmf you can use PCI passthrough (also called hostdev) to pass the PCI device entirely into the VM. Then you run CapsuleApp.efi (built from MdeModulePkg) in UEFI shell in that VM and pass the capsule as first parameter. That's all there is to it.

I can share my libvirt XML containing the hostdev configuration if you'd like.

Cheers,
Tom

How can I test this?

Thanks,
