This series finally fixes -icount with iothread and avoids deadlocks
due to the vm_clock not making progress when the VM is stopped.
The crux of the fix is in patch 1, while patch 2 implements the

the nanosecond resolution rt_clock

The previous patch however is not enough, because if the virtual CPU
goes to sleep waiting for a future timer interrupt to wake it up, qemu
deadlocks. The timer interrupt never comes because time is driven by
icount, but the vCPU doesn't run any insns.
You could say that VCPUs should never go to
The correct fix for -icount is to consider the biggest difference
between iothread and non-iothread modes. In the traditional model,
CPUs run _before_ the iothread calls select (or WaitForMultipleObjects
for Win32). In the iothread model, CPUs run while the iothread
isn't holding the mutex, i.e.

Yes it does. STC encoding A1 is: cond:4 110 p u d w 0 rn:4 crd:4 coproc:4 imm:8
For STC the combination of P=0 U=0 D=0 W=0 is UNDEFINED, but it's still in STC

Actually, the undefined instruction that I have used is documented as
undefined at two places in ARM Instruction Set Encoding section of ARMv7a

2. Refer A8.6.188 STC, STC2

Sorry, I didn't notice the footnote in table A5-22; I see what you mean
now. It's still not permanently-UNDEF space though and you'd really be
better off using that instead. In any case, qemu does properly UNDEF the
instruction so this is a bit of a diversion.

This series finally fixes -icount with iothread and avoids deadlocks

The crux of the fix is in patch 1, while patch 2 implements the

This patch adds a global get_rsdp() function call and refactors
find_resume_vector() to call it.

This patch implements the TCG BIOS interrupt handler 1ah. It is for
example used by trusted grub.
This patch adds an implementation of SHA1 (following NIST specs., IETF RFC 3147
and Wikipedia) for speeding up measurements of code. Trusted Grub for example
makes use of this interface and measures
The following set of patches add TPM and Trusted Computing support to SeaBIOS.
In particular the patches add:
- a TPM driver for the Qemu's TPM TIS emulation (not yet in Qemu git)
- ACPI support for the TPM device (SSDT table)
- ACPI support for measurement logging (TCPA table)
- Support for
This patch implements the main part of the TCG BIOS extensions. It provides
the following functionality:
- initialization of the TCPA ACPI table used for logging of measurements
- initialization of the TPM by sending a sequence of commands to it
- proper setup of the TPM once the BIOS hands over
This patch adds an implementation of a TPM TIS driver for the TPM TIS
emulation supported by Qemu (patches posted, not in git yet). Usage of the
driver is broken up into several functions. The driver is cleanly separated
from the rest of the code through an interface holding pointers to the
This patch provides an addtional menu entry that enables the user to control
certain aspects of the TPM.
If a working TPM has been detected, the top level BIOS menu
will look like this:
Press F12 for boot menu.
Press F11 to TPM menu.
Upon pressing F11 the TPM menu will be shown:
1. Enable TPM
This patch provides ACPI support for the TPM device. It probes for the TPM
device and only if a TPM device is found then the TPM's SSDT and TCPA table
are created. This patch also connects them to the RSDT.
Since the logging area in the TCPA table requires 64kb, the memory reserved
for ACPI
This patch adds an optional test suite (CONFIG_TIS_TEST) for the TIS interface
to SeaBIOS. If compiled into the BIOS, it can be invoked through the
TPM-specific menu item 8.
1. Enable TPM
2. Disable TPM
3. Activate TPM
4. Deactivate TPM
5. Clear ownership
6. Allow installation of owner

This patch adds invocactions of functions that measure various parts of the
code and data through various parts of the BIOS code. It follows TCG
specifications on what needs to be measured. It also adds the implementation
of the called functions.

The GET_EVENT_STATUS_NOTIFICATION ATAPI command is listed as a
mandatory command in the spec but we don't really implement it any of
its sub-commands.
The commit message for the last commit explains why implementing just
the media subcommand is helpful and how it goes a long way in getting
