* tpm_crb: Avoid backend startup just before shutdown under XenRoss Lagerwall2022-09-091-1/+6
| | | | | | | | | | | | | | | | | | When running under Xen and the guest reboots, it boots into a new domain with a new QEMU process (and a new swtpm process if using the emulator backend). The existing reset function is triggered just before the old QEMU process exists which causes QEMU to startup the TPM backend and then immediately shut it down. This is probably harmless but when using the emulated backend, it wastes CPU and IO time reloading state, etc. Fix this by calling the reset function directly from realize() when running under Xen. During a reboot, this will be called by the QEMU process for the new domain.

| | | | | | | | | | | | | | | | At the moment, there doesn't seems to be any way to know that QEMU made modification to the command buffer. This is potentially an issue on Xen while migrating a guest, as modification to the buffer after the migration as started could be ignored and not transfered to the destination.

| | | | | | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

| | | | | | | | | | | | | | | | | | | | | | | Implement a virtual memory device for the TPM Physical Presence interface. The memory is located at 0xFED45000 and used by ACPI to send messages to the firmware (BIOS) and by the firmware to provide parameters for each one of the supported codes. This interface should be used by all TPM devices on x86 and can be added by calling tpm_ppi_init_io(). Note: bios_linker cannot be used to allocate the PPI memory region, since the reserved memory should stay stable across reboots, and might be needed before the ACPI tables are installed.

tpm_crb is a device for TPM 2.0 Command Response Buffer (CRB) Interface as defined in TCG PC Client Platform TPM Profile (PTP) Specification Family “2.0” Level 00 Revision 01.03 v22. The PTP allows device implementation to switch between TIS and CRB model at run time, but given that CRB is a simpler device to implement, I chose to implement it as a different device. The device doesn't implement other locality than 0 for now (my laptop TPM doesn't either, so I assume this isn't so bad) Tested with some success with Linux upstream and Windows 10, seabios & modified ovmf. The device is recognized and correctly transmit command/response with passthrough & emu. However, we are missing PPI ACPI part atm.
