An assertion failure can be triggered in the lsi53c810 emulator by a guest
when ((s->sstat1 & 0x7) == PHASE_DO) || (s->sstat1 & 0x7) == PHASE_DI)) &&
(!s->current) holds.
Check s->sstat1 and s->current in lsi_reg_writeb before lsi_execute_script()
to discard this MMIO write.

A g_assert_not_reached of vmxnet3 can be triggered by a guest with the root
privilege.
Remove the VMXNET3_REG_ICR branch thus get rid of this crash.

Touches the same iotest output as
The parameters of intel-iommu device are non-trivial to understand. Add an
entry for it so that people can reference to it when using.
There're actually a few more options there, but I hide them explicitly because
they shouldn't be used by normal QEMU users.

This change provides a qtest that locates and then does a simple
interrogation of the ERST feature within the guest.

This change implements the support for the ACPI ERST feature[1,2].
To utilize ACPI ERST, a memory-backend-file object and acpi-erst
device must be created, for example:
qemu ...
-object memory-backend-file,id=erstram,mem-path=acpi-erst.backing,
size=0x1,shared=on
-device acpi-erst,memdev
Following the guidelines in tests/qtest/bios-tables-test.c, this
change adds empty placeholder files per step 1 for the new ERST
table, and excludes resulting changed files in bios-tables-test-allowed-diff.h
per step 2.

is step 6, the re-generated ACPI tables binary blobs.

This patchset introduces support for the ACPI Error Record
Serialization Table, ERST.
Linux uses the persistent storage filesystem, pstore, to record
information (eg. dmesg tail) upon panics and shutdowns. Pstore is
independent of, and runs before, kdump. In certain scenarios (ie.
hosts/guests w
Ping.
Only patches 06 and 07 did not get any review.
The series touches many files and it was last rebased months ago, so
likely I will need to resolve rebase conflicts. But I would like to have
the reviews of those patches before.
Thanks!

It's leaked, so I doubt anybody who's paid to work on Linux or QEMU
would touch that with a ten-foot pole.
