8d55280160 tests/docker: updates to alpine package list
Cleanup the package lists by removing some entries that we don't need to
directly reference

  binutils: implied by the compiler toolchain
  coreutils: not required by QEMU build
  mesa-egl mesa-gbm: implied by mesa-dev
  ninja: alias for samurai package
  shadow: not required by QEMU build
  util-linux-dev: not directly required by QEMU build

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
With latest clang 13.0.0 we get

../ui/clipboard.c:47:34: error: variable 'old' set but not used [-Werror,-Wunused-but-set-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.

33fa43e053 ppc/pnv: remove PnvPhb4PecStack object
All the complexity that was scattered between PnvPhb4PecStack and
PnvPHB4 are now centered in the PnvPHB4 device. PnvPhb4PecStack does not
serve any purpose in the current code base.

3f4c369ea6 ppc/pnv: make PECs create and realize PHB4s
This patch changes the design of the PEC device to create and realize PHB4s
instead of PecStacks. After all the recent changes, PHB4s now contain all
the information needed for their proper functioning, not relying on PecStack
in any capacity.

All changes are being made in a single patch to avoid renaming parts of
the PecState and leaving the code in a strange way. E.g. rename
PecClass->num_stacks to num_phbs, which would then read a
pnv_pec_num_stacks[] array. To avoid mixing the old and new design more
than necessary it's clearer to do these changes in a single step.

The name changes made are:

- in PnvPhb4PecState:
  * rename 'num_stacks' to 'num_phbs'
  * remove the pec->stacks[] array. Current code relies on the
pec->stacks[] obj acting as a simple container, without ever accessing
pec->stacks[] for any other purpose. Instead of converting this into a
pec->phbs[] array, remove it

- in PnvPhb4PecClass, rename *num_stacks to *num_phbs;

- pnv_pec_num_stacks[] is renamed to pnv_pec_num_phbs[].

The logical changes:

- pnv_pec_default_phb_realize():
  * init and set the properties of the PnvPHB4 qdev
  * do not use stack->phb anymore;

- pnv_pec_realize():
  * use the new default_phb_realize() to init/realize each PHB if
running with defaults;

- pnv_pec_instance_init(): removed since we're creating the PHBs during
pec_realize();

- pnv_phb4_get_stack():
  * renamed to pnv_phb4_get_pec() and returns a PnvPhb4PecState*;

- pnv_phb4_realize(): use 'phb->pec' instead of 'stack'.

This design change shouldn't caused any behavioral change in the runtime
of the machine.

Move the current pnv_pec_stk_default_phb_realize() call to
pec_realize(), renaming the function to pnv_pec_default_phb_realize(),
and set the PHB attributes using the PEC object directly.

This will be important to allow for PECs devices to handle PHB4s
directly later on.

7e67e0a9f0 ppc/pnv: remove stack pointer from PnvPHB4
This pointer was being used for two reasons: pnv_phb4_update_regions()
was using it to access the PHB and phb4_realize() was using it as a way
to determine if the PHB was user created.

We can determine if the PHB is user created via phb->pec, introduced in
the previous patch, and pnv_phb4_update_regions() is no longer using
stack->phb.

Remove the pointer from the PnvPHB4 device.

6f506c90c3 ppc/pnv: reduce stack->stack_no usage
'stack->stack_no' represents the order that a stack appears in its PEC.
Its primary use is in XSCOM address space calculation in
pnv_phb4_xscom_realize() when calculating the memory region offset.

This attribute is redundant with phb->phb_id, which is calculated via
pnv_phb4_pec_get_phb_id() using stack->stack_no information. It'll also
be awkward to assign it when dealing with PECs and PHBs only in a future
patch.

A new pnv_phb4_get_phb_stack_no() helper is introduced to eliminate most
of the stack->stack_no uses we have. The only use left after this patch
is during pnv_pec_stk_default_phb_realize() when calculating phb_id,
which will also handled in the next patches.

867683d86e ppc/pnv: move nest_regs_mr to PnvPHB4
We're now able to cleanly move nest_regs_mr to the PnvPHB4 device.

One thing of notice here is the need to use a phb->stack->pec pointer
because pnv_pec_stk_nest_xscom_write requires a PEC object. Another
thing that can be noticed in the use of 'stack->stack_no' that still
remains throughout the XSCOM code.

After moving all MemoryRegions to the PnvPHB4 object, this illustrates
what is the remaining role of the stack: provide a PEC pointer and the
'stack_no' information. If we can provide these in the PnvPHB4 object
instead (spoiler: we can, and we will), the PnvPhb4PecStack device will
be deprecated and can be removed.

e19e998ce2 ppc/pnv: change pnv_pec_stk_update_map() to use PnvPHB4
stack->nest_regs_mr wasn't migrated to PnvPHB4 together with phb->nest_regs[] in
the previous patch. We were unable to cleanly convert its write MemoryRegionOps,
pnv_pec_stk_nest_xscom_write(), to use PnvPHB4 instead of PnvPhb4PecStack due to
pnv_pec_stk_update_map() using a stack. Thing is, we're now able to convert
pnv_pec_stk_update_map() because of what the did in previous patch.

The need for this intermediate step is a good example of the interconnected
relationship between stack and phb that we aim to cleanup.

5d4ec10341 ppc/pnv: use PHB4 obj in pnv_pec_stk_pci_xscom_ops
The current relationship between PnvPhb4PecStack and PnvPHB4 objects is
overly complex. Recent work done in pnv_phb4.c and pnv_phb4_pec.c shows
that the stack obj role in the overall design is more of a placeholder for
its 'phb' object, having no atributes that stand on its own. This became
clearer after pnv-phb4 user creatable devices were implemented.

What remains now are a lot of stack->phb and phb->stack pointers
throughout .read and .write callbacks of MemoryRegionOps that are being
initialized in phb4_realize() time. stk_realize() is a no-op if the
machine is being run with -nodefaults.

The first step of trying to decouple the stack and phb relationship is
to move the MemoryRegionOps that belongs to PnvPhb4PecStack to PhbPHB4.
Unfortunately this can't be done  without some preliminary steps to
change the usage of 'stack' and replace it with 'phb' in these
read/write callbacks.

This patch starts this process by using a PnvPHB4 opaque in
pnv_pec_stk_pci_xscom_ops instead of PnvPhb4PecStack.
