[Qemu-devel] [PATCH 0/2] Add vTPM emulator supportfor ppc64 platform

[Stefan Berger]

The following series of patches adds vTPM emulator support for the
ppc64 platform (pSeries). 

It can be tested as follows with swtpm/libtpms:

#> swtpm socket --tpmstate dir=/tmp/mytpm1 \
        --ctrl type=unixio,path=/tmp/mytpm1/ctrl.sock \
        --log level=2

If TPM 2 is desired, add --tpm2 as parameter to the above
and use the latest tpm2-preview branches of libtpms and swtpm.

In another terminal start QEMU:

#> sudo ./ppc64-softmmu/qemu-system-ppc64 -m 1024 \
        -monitor stdio -vnc :12 -vga std \
        --chardev socket,id=chrtpm,path=/tmp/mytpm1/ctrl.sock \
        -tpmdev emulator,id=tpm0,chardev=chrtpm \
        -device tpm-spapr,tpmdev=tpm0 \
        -L /tmp -bios boot_rom.bin \
        myimage.raw
