acpi: pc/q35: drop ad-hoc PCI-ISA bridge AML routines and let bus ennumeration generate AML

PCI-ISA bridges that are built in PIIX/Q35 are building its own AML
using AcpiDevAmlIf interface. Now build_append_pci_bus_devices()
gained AcpiDevAmlIf interface support to get AML of devices atached
to PCI slots.
So drop ad-hoc build_q35_isa_bridge()/build_piix4_isa_bridge()
and let PCI bus enumeration to include PCI-ISA bridge AML
when it's enumerated by build_append_pci_bus_devices().

AML change is mostly contextual, which moves whole ISA hierarchy
directly under PCI host bridge instead of it being described
as separate \SB.PCI0.ISA block.

Note:
If bus/slot that hosts ISA bridge has BSEL set, it will gain new
ASUN and _DMS entries (i.e. acpi-index support, but it should not
cause any functional change and that is fine from PCI Firmware
spec point of view), potentially it's possible to suppress that
by adding a flag to PCIDevice but I don't see a reason to do that
yet, I'd rather treat bridge just as any other PCI device if it's
possible.

vhost-user: Fix out of order vring host notification handling

vhost backend sends host notification for every VQ. If backend creates
VQs in parallel, the VHOST_USER_SLAVE_VRING_HOST_NOTIFIER_MSG may
arrive to QEMU in different order than incremental queue index order.

For example VQ 1's message arrive earlier than VQ 0's:
After alloc VhostUserHostNotifier for VQ 1. GPtrArray becomes

    [ nil, VQ1 pointer ]

After alloc VhostUserHostNotifier for VQ 0. GPtrArray becomes

    [ VQ0 pointer, nil, VQ1 pointer ]

This is wrong. fetch_notifier will return NULL for VQ 1 in
vhost_user_get_vring_base, causes host notifier miss removal(leak).

The fix is to remove current element from GPtrArray, make the right
position for element to insert.

hw/virtio/virtio-iommu-pci: Enforce the device is plugged on the root bus

In theory the virtio-iommu-pci could be plugged anywhere in the PCIe
topology and as long as the dt/acpi info are properly built this should
work. However at the moment we fail to do that because the
virtio-iommu-pci BDF is not computed at plug time and in that case
vms->virtio_iommu_bdf gets an incorrect value.

For instance if the virtio-iommu-pci is plugged onto a pcie root port
and the virtio-iommu protects a virtio-block-pci device the guest does
not boot.

So let's do not pretend we do support this case and fail the initialize()
if we detect the virtio-iommu-pci is plugged anywhere else than on the
root bus. Anyway this ability is not needed.

biosbits to execute. No change has been made to them from the original code
written by the biosbits author Josh Triplett. They are required to be installed
into the bits iso file and then run from within the virtual machine booted off
with biosbits iso.

The test scripts have a ".py2" extension in order to prevent avocado from
loading them. They are written in python 2.7 and are run from within bios bits.
There is no need for avocado to try to load them and call out errors on python3
specific syntaxes.

The original location of these tests are here:
https://github.com/biosbits/bits/blob/master/python/testacpi.py
https://github.com/biosbits/bits/blob/master/python/smbios.py
https://github.com/biosbits/bits/blob/master/python/testcpuid.py

19 months agohw/i386/e820: remove legacy reserved entries for e820
Ani Sinha [Wed, 31 Aug 2022 04:53:10 +0000 (10:23 +0530)]
hw/i386/e820: remove legacy reserved entries for e820

e820 reserved entries were used before the dynamic entries with fw config files
were intoduced. Please see the following change:
7d67110f2d9a6("pc: add etc/e820 fw_cfg file")

Identical support was introduced into seabios as well with the following commit:
ce39bd4031820 ("Add support for etc/e820 fw_cfg file")

Both the above commits are now quite old. QEMU machines 1.7 and newer no longer
use the reserved entries. Seabios uses fw config files and
dynamic e820 entries by default and only falls back to using reserved entries
when it has to work with old qemu (versions earlier than 1.7). Please see
functions qemu_cfg_e820() and qemu_early_e820(). It is safe to remove legacy
FW_CFG_E820_TABLE and associated code now as QEMU 7.0 has deprecated i440fx
machines 1.7 and older. It would be incredibly rare to run the latest qemu
version with a very old version of seabios that did not support fw config files
for e820.

As far as I could see, edk2/ovfm never supported reserved entries and uses fw
config files from the beginning. So there should be no incompatibilities with
ovfm as well.

target/openrisc: Use cpu_unwind_state_data for mfspr

Since we do not plan to exit, use cpu_unwind_state_data
and extract exactly the data requested.

This is a bug fix, in that we no longer clobber dflag.

Consider:

        l.j       L2         // branch
        l.mfspr   r1, ppc    // delay

L1:     boom
L2:     l.lwa     r3, (r4)

Here, dflag would be set by cpu_restore_state (because that is the current
state of the cpu), but but not cleared by tb_stop on exiting the TB
(because DisasContext has recorded the current value as zero).

The next TB begins at L2 with dflag incorrectly set.  If the load has a
tlb miss, then the exception will be delivered as per a delay slot:
with DSX set in the status register and PC decremented (delay slots
restart by re-executing the branch). This will cause the return from

tests/avocado: raspi2_initrd: Wait for guest shutdown message before stopping

The avocado test
 tests/avocado/boot_linux_console.py:BootLinuxConsole.test_arm_raspi2_initrd
finishes with

    exec_command(self, 'halt')
    # Wait for VM to shut down gracefully
    self.vm.wait()

In theory this should be fine. In practice it runs into two bugs:

 * when the test calls self.vm.wait() Avocado closes the socket
   connection to the guest serial console immediately, so the
   avocado logs don't have the last part of the guest output:
   https://gitlab.com/qemu-project/qemu/-/issues/1265
 * when the socket is closed, a bug in the QEMU socket chardev
   means that it loses any data that the guest UART has not
   yet consumed. This means that the guest doesn't always read
   the full 'halt' command string, so the test intermittently
   fails with a timeout:
   https://gitlab.com/qemu-project/qemu/-/issues/1264

Work around both of these by waiting for the guest to print the
string that means it has completed the shutdown process.  This fixes
a very long standing intermittent failure in this test.
