In commit b0fcc6fc7f ("build: rebuild build.ninja using
"meson setup --reconfigure"", 2023-05-19) I changed the build.ninja
rule in the Makefile to use "meson setup" so that the Makefile would
pick up a changed path to the meson binary.
However, there was a reason why build.ninja was rebuilt using $(NINJA)
itself. Namely, ninja has its own cache of file modification times,
and if it does not know about the modification that was done outside
its control, it will *also* try to regenerate build.ninja. This can be
simply by running "make" on a fresh tree immediately after "configure";
that will trigger an unnecessary meson run.
So, apply a refinement to the rule in order to cover both cases:
- track the meson binary that was used (and that is embedded in
build.ninja's reconfigure rules); to do this, write build.ninja.stamp
right after executing meson successfully
- if it changed, force usage of "$(MESON) setup --reconfigure" to
update the path in the reconfigure rule
- if it didn't change, use "$(NINJA) build.ninja" just like before
commit b0fcc6fc7f.

In forks QEMU_CI=1 can be used to create a pipeline but not auto-run any

This supports setting QEMU_CI=1 in upstream, to disable job auto-run.
This can be used to preserve CI minutes if repushing a branch to staging

If the stable staging branches publish containers under the 'latest' tag
they will clash with containers published on the primary staging branch,
as well as with each other. This introduces logic that overrides the
container tag when jobs run against the stable staging branches.
The CI_COMMIT_REF_SLUG variable we use expands to the git branch name,
but with most special characters removed, such that it is valid as a

The CI rules have special logic for what happens in upstream. To enable
contributors who modify CI rules to test this logic, however, they need
to be able to override which repo is considered upstream. This
introduces the 'QEMU_CI_UPSTREAM' variable
git push gitlab <branch> -o ci.variable=QEMU_CI_UPSTREAM=berrange
to make it look as if my namespace is the actual upstream. Namespace in
this context refers to the path fragment in gitlab URLs that is above
the repository. Typically this will be the contributor's gitlab login

We use a fixed container tag of 'latest' so that contributors' forks
don't end up with an ever growing number of containers as they work
on throwaway feature branches.
This fixed tag causes problems running CI upstream in stable staging
branches, however, because the stable staging branch will publish old
container content that clashes with that needed by primary staging
branch. This makes it impossible to reliably run CI pipelines in
parallel in upstream for different staging branches.
This introduces $QEMU_CI_CONTAINER_TAG global variable as a way to
change which tag container publishing uses. Initially it can be set
by contributors as a git push option if they want to override the
default use of 'latest' eg
git push gitlab <branch> -o ci.variable=QEMU_CONTAINER_TAG=fish
this is useful if contributors need to run pipelines for different
branches concurrently in their forks.

Accessing the TIMA from some specific ring/offset combination can
trigger a special operation, with or without side effects. It is
implemented in qemu with an array of special operations to compare
accesses against. Since the presenter on P10 is pretty similar to P9,
we had the full array defined for P9 and we just had a special case
for P10 to treat one access differently. With a recent change,
6f2cbd133d ("pnv/xive2: Handle TIMA access through all ports"), we
now ignore some of the bits of the TIMA address, but that patch
managed to botch the detection of the special case for P10.
To clean that up, this patch introduces a full array of special ops to
be used for P10. The code to detect a special access is common with
P9, only the array of operations differs. The presenter can pick the
correct array of special ops based on its configuration introduced in
a previous patch.

This requires PIR and TIR be set, because that's how sibling thread
matching is done by TCG.

that combination is prohibited (interestingly somewhat analogous to

The top bits of the LEV field of the sc instruction are to be treated as
as a reserved field rather than a reserved value, meaning LEV is
effectively the bottom bit. LEV=0xF should be treated as LEV=1 and be
a hypercall, for example.
This changes the instruction execution to just set lev from the low bit
of the field. Processors which don't support the LEV field will continue
to ignore it.
ISA v3.1 defines LEV to be 2 bits, in order to add the 'sc 2' ultracall
instruction. TCG does not support Ultravisor, so don't worry about

The case of instruction fetch that causes an HDSI due to access of a
process-scoped table faulting on the partition scoped translation is the
tricky one. As with ISIs and HISIs, this does not try to set the prefix
bit because there is no instruction image to be loaded. The HDSI needs
the originating access type to be passed through to the handler to
distinguish this from HDSIs that fault translating process scoped tables
originating from a load or store instruction (in that case the prefix

which is why this series updates it to version 8 which includes those
fixes and enhancements:
Fixes
- boot of HP-UX with SMP, and
- reboot of Linux and HP-UX with SMP
Enhancements:
- show qemu version in boot menu
- adds exit menu entry in boot menu to quit emulation
- allow to trace PCD_CHASSIS codes more specifically

Give current QEMU version string to SeaBIOS-hppa via fw_cfg interface so
that the firmware can show the QEMU version in the boot menu info.

When the OS triggers a reboot, the reset helper function sends a
qemu_system_reset_request(SHUTDOWN_CAUSE_GUEST_RESET) together with an
EXCP_HLT exception to halt the CPUs.
So, at reboot when initializing the CPUs again, make sure to set all
instruction pointers to the firmware entry point, disable any interrupts,
disable data and instruction translations, enable PSW_Q bit and tell qemu
to unhalt (halted=0) the CPUs again.
This fixes the various reboot issues which were seen when rebooting a
Linux VM, including the case where even the monarch CPU has been virtually
halted from the OS (e.g. via "chcpu -d 0" inside the Linux VM).

The xkb official name for the Arabic keyboard layout is 'ara'.
However xkb has for at least the past 15 years also permitted it to
be named via the legacy synonym 'ar'. In xkeyboard-config 2.39 this
synoynm was removed, which breaks compilation of QEMU:
FAILED: pc-bios/keymaps/ar
/home/fred/qemu-git/src/qemu/build-full/qemu-keymap -f pc-bios/keymaps/ar -l ar
xkbcommon: ERROR: Couldn't find file "symbols/ar" in include paths
xkbcommon: ERROR: 1 include paths searched:
xkbcommon: ERROR: /usr/share/X11/xkb
xkbcommon: ERROR: 3 include paths could not be added:

xkbcommon: ERROR: /etc/xkb
xkbcommon: ERROR: Abandoning symbols file "(unnamed)"
xkbcommon: ERROR: Failed to compile xkb_symbols
xkbcommon: ERROR: Failed to compile keymap
The upstream xkeyboard-config change removing the compat
mapping is:
470ad2cd8f
Make QEMU always ask for the 'ara' xkb layout, which should work on
both older and newer xkeyboard-config. We leave the QEMU name for
this keyboard layout as 'ar'; it is not the only one where our name
for it deviates from the xkb standard name.

One cannot test for feature aa32_simd_r32 without first
testing if AArch32 mode is supported at all. This leads to
qemu-system-aarch64: ARM CPUs must have both VFP-D32 and Neon or neither
for Apple M1 cpus.
We already have a check for ARMv8-A never setting vfp-d32 true,
so restructure the code so that AArch64 avoids the test entirely.
