KVM does not allow memory regions > KVM_MEM_MAX_NR_PAGES, basically
limiting the memory per slot to 8TB-4k. As memory slots on s390/kvm must
be a multiple of 1MB we need start a new memory region if we cross
8TB-1M.
With that (and optimistic overcommitment in the kernel) I was able to
start a 24TB guest on a 1TB system.

If the requested buffer size of the frontend is smaller than the fixed
buffer size of the host's TPM, fail the startup_tpm() interface function,
which will make the device unusable. We fail it because the backend TPM
could produce larger packets than what the frontend could pass to the OS.
The current combination of TIS frontend and either passthrough or emulator
backend will not lead to this case since the TIS can support any size of
buffer.

The TPM backend processing thread has common shared variable race
issues. (they should not be so easy to reach since guest interaction
with the device is slow compared to host emulation)
An obvious one is setting op_cancelled from device thread after
calling write(cancel_fd). The backend thread may return before the
device thread has set the variable. Instead set it before
cancellation. Even if the write() failed, the end result is command
get possibly cancelled (even if cancellation came from external
sources it doesn't matter much).
It's worth to consider removing the backend processing thread for now.

The passed-through device might be an express device. In this case the
old code allocated a too small emulated config space in
pci_config_alloc() since pci_config_size() returned the size for a
non-express device. This leads to an out-of-bound write in
xen_pt_config_reg_init(), which sometimes results in crashes. So set
is_express as already done for KVM in vfio-pci.

Without activation, the input events are delivered to handlers
registered earlier, which would be the emulated USB tablet or
emulated PS/2 mouse.

Writes "feature-raw-pointer" during init to indicate the backend
can pass raw unscaled values for absolute axes to the frontend.
Frontends set "request-raw-pointer" to indicate the backend should
not attempt to scale absolute values to console size.
"request-raw-pointer" is only valid if "request-abs-pointer" is
also set. Raw unscaled pointer values are in the range [0, 0x7fff]
"feature-raw-pointer" and "request-raw-pointer" added to Xen
header in commit 7868654ff7fe5e4a2eeae2b277644fa884a5031e
