11b9eb1b8a hw/acpi/aml-build: Improve scalability of PPTT generation
Use g_queue APIs to reduce the nested loops and code indentation
with the processor hierarchy levels increasing. Consenquently,
it's more scalable to add new topology level to build_pptt.

No functional change intended.

d55c316f91 hw/arm/virt: Support CPU cluster on ARM virt machine
ARM64 machines like Kunpeng Family Server Chips have a level
of hardware topology in which a group of CPU cores share L3
cache tag or L2 cache. For example, Kunpeng 920 typically
has 6 or 8 clusters in each NUMA node (also represent range
of CPU die), and each cluster has 4 CPU cores. All clusters
share L3 cache data, but CPU cores in each cluster share a
local L3 tag.

Running a guest kernel with Cluster-Aware Scheduling on the
Hosts which have physical clusters, if we can design a vCPU
topology with cluster level for guest kernel and then have
a dedicated vCPU pinning, the guest will gain scheduling
performance improvement from cache affinity of CPU cluster.

So let's enable the support for this new parameter on ARM
virt machines. After this patch, we can define a 4-level
CPU hierarchy like: cpus=*,maxcpus=*,sockets=*,clusters=*,
cores=*,threads=*.

95ea96e8b1 hw/arm/virt: KVM: Enable PAuth when supported by the host
Add basic support for Pointer Authentication when running a KVM
guest and that the host supports it, loosely based on the SVE
support.

Although the feature is enabled by default when the host advertises
it, it is possible to disable it by setting the 'pauth=off' CPU
property. The 'pauth' comment is removed from cpu-features.rst,
as it is now common to both TCG and KVM.

Tested on an Apple M1 running 5.16-rc6.

3265d1fc77 docker: include bison in debian-tricore-cross
Binutils sometimes fail to build if bison is not installed:

  /bin/sh ./ylwrap `test -f arparse.y || echo ./`arparse.y y.tab.c arparse.c y.tab.h arparse.h y.output arparse.output --  -d
  ./ylwrap: 109: ./ylwrap: -d: not found

(the correct invocation of ylwrap would have "bison -d" after the double
dash).  Work around by installing it in the container.

190674f371 linux-user: don't adjust base of found hole
The pgb_find_hole function goes to the trouble of taking account of
both mmap_min_addr and any offset we've applied to decide the starting
address of a potential hole. This is especially important for
emulating 32bit ARM in a 32bit build as we have applied the offset to
ensure there will be space to map the ARM_COMMPAGE bellow the main
guest map (using wrapped arithmetic).

11d3672788 linux-user: expand reserved brk space for 64bit guests
A recent change to fix commpage allocation issues on 32bit hosts
revealed another intermittent issue on s390x. The root cause was the
headroom we give for the brk space wasn't enough causing the guest to
attempt to map something on top of QEMUs own pages. We do not
currently do anything to protect from this (see #555).

By inspection the brk mmap moves around and top of the address range
has been measured as far as 19Mb away from the top of the binary. As
we chose a smallish number to keep 32bit on 32 bit feasible we only
increase the gap for 64 bit guests. This does mean that 64-on-32
static binaries are more likely to fail to find a hole in the address
space but that is hopefully a fairly rare situation.

Generally a guest needs an external source of randomness to properly

components having random data in the DTB will cause verification to
fail. Add a control knob so we can prevent this being added to the

The two more or less overlap, because CONFIG_LINUX is a requirement for Linux

that applies even to system emulation.  Defining CONFIG_LINUX_USER, and
CONFIG_BSD_USER for eventual future use, is cleaner.

c45a540f4b .gitlab-ci.d/cirrus: auto-generate variables with lcitool
The current Cirrus CI variables files were previously generated by using
lcitool. This change wires them up to the refresh script to make that
link explicit.

This changes the package list because libvirt-ci now knows about the
mapping for dtc on FreeBSD and macOS platforms.

The variables are also now emit in sorted order for stability across
runs.

4ebb040f1f tests: integrate lcitool for generating build env manifests
This introduces

  https://gitlab.com/libvirt/libvirt-ci

as a git submodule at tests/lcitool/libvirt-ci

The 'lcitool' program within this submodule will be used to
automatically generate build environment manifests from a definition
of requirements in tests/lcitool/projects/qemu.yml

It will ultimately be capable of generating

 - Dockerfiles
 - Package lists for installation in VMs
 - Variables for configuring Cirrus CI environments

When a new build pre-requisite is needed for QEMU, if this package
is not currently known to libvirt-ci, it must first be added to the
'mappings.yml' file in the above git repo.

Then the submodule can be updated and the build pre-requisite added
to the tests/lcitool/projects/qemu.yml file. Now all the build env
manifests can be re-generated using  'make lcitool-refresh'

This ensures that when a new build pre-requisite is introduced, it
is added to all the different OS containers, VMs and Cirrus CI
environments consistently.

It also facilitates the addition of containers targetting new distros
or updating existing containers to new versions of the same distro,
where packages might have been renamed.

f178c62afc ci: explicitly skip I/O tests on alpine
The block I/O tests don't work on Alpine because their alternative libc
impl emits different strings for errnos, which breaks the expected
output matching. e.g.

=== IO: pattern 102
 wrote 512/512 bytes at offset 512
 512 bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec)
-qemu-img: Error while reading offset 0 of blkdebug:TEST_DIR/blkdebug.conf:TEST_DIR/t.IMGFMT: Input/output error
+qemu-img: Error while reading offset 0 of blkdebug:TEST_DIR/blkdebug.conf:TEST_DIR/t.IMGFMT: I/O error
 4
 Formatting 'TEST_DIR/t.IMGFMT', fmt=IMGFMT size=1073741824
 Formatting 'TEST_DIR/t.IMGFMT.2', fmt=IMGFMT size=0

Currently the I/O tests are skipped as a side effect of the Alpine image
containing a minimal busybox 'sed' binary, rather than GNU sed. This is
a fragile assumption that will be invalidated when the dockerfile is
changed to be autogenerated from a standardized package list that
includes GNU sed.

70a54b0169 ui: avoid compiler warnings from unused clipboard info variable

    g_autoptr(QemuClipboardInfo) old = NULL;
                                 ^

The compiler can't tell that we only declared this variable in
order to get the side effect of free'ing it when out of scope.

This pattern is a little dubious for a use of g_autoptr, so
rewrite the code to avoid it.

b2173046a6 s390x/ipl: support extended kernel command line size
In the past s390 used a fixed command line length of 896 bytes. This has changed
with the Linux commit 5ecb2da660ab ("s390: support command lines longer than 896
bytes"). There is now a parm area indicating the maximum command line size. This
parm area has always been initialized to zero, so with older kernels this field
would read zero and we must then assume that only 896 bytes are available.
