This series adds the capability to instantiate an MMIO TPM TIS
in ARM virt.
The series was tested with the swtpm/libtpms emulator.
Automatic guest LUKS volume unlocking (tpm2) was successful.
EDK2 support is under development [3]. Thanks to Ard
for supporting me when setting up the test environment.
Best Regards
Eric
Testing:
mkdir /tmp/tpm
swtpm socket \
--tpm2 \
-t -d \
--tpmstate dir=/tmp/tpm \
--ctrl type=unixio,path=/tmp/swtpm-sock
qemu command line must be augmented with the following options:
-chardev socket,id=chrtpm,path=/tmp/swtpm-sock \
-tpmdev emulator,id=tpm0,chardev=chrtpm \
-device tpm-tis,tpmdev=tpm0 \
