Hi Ard,
Just my curious, are you supporting the below idea of QEMU in UEFI?

Hi Zenith,
I like your patch. Sorry for the late response. I see your patch has no impact
to current supported relocation types, and I also hope we can add more
relocation types in our GenFw tool.

Hi Marcandre,
Thanks for your command steps and I tried them, but my qemu failed to connect
the socket tpmemu.sock. When I added the control channel to the TPM, the swtpm
socket command stuck there and never exit. Not sure whether it was successful.
Below are the command steps running output in

Where is the swtpm_setup.sh? And could you tell how to build & install the

Hi Laszlo,
How could we configure the Qemu and test the UDF driver on OVMF?
BTW, how could we configure the Qemu to create a full feature scope machine to
include all possible devices in it, e.g. USB, ISA, SD/MMC, network etc.
