Re: OVMF package : Question about Qemu/Xen support

["Tiger Liu(BJ-RD)" <TigerLiu@zhaoxin.com>]

Hi, Laszlo:
I have a question you would like to ask you.
Could I study pcie native hot plug feature with ovmf?

It seems qemu emulates Q35 chipset.
And ovmf provides PciHotPlugInitDxe driver.

Thanks

Best wishes,
