The following series of patches adds TPM (Trusted Platform Module) support

example Linux's TPM TIS (tpm_tis) driver.
In this series I am posting a backend implementation that makes use of the
host's TPM through a passthrough driver, which on Linux is accessed
using /dev/tpm0.
Looks pretty clean, ACK to patches 1-4.
Thanks.
The passthrough mode is quite easy to misuse, though most
of the problem is in the hardware, not on our side.
I'm still trying to think of a good way to warn users
about the pitfalls with that. Disabling by default in configure, unless
The documentation isn't enough? If it's really needed could I add
another patch on top of the existing V11?
explictly required, is certainly one way.
And/or, let's rename it 'assigned' mode to resemble the name of
another fragile qemu feature :) Only half joking ...
Well, not sure what exactly you mean, but some things seem late versus
closing time...
