Jobs based on custom runners: add CentOS Stream 8
This introduces three different parts of a job designed to run
on a custom runner managed by Red Hat. The goals include:
a) propose a model for other organizations that want to onboard
their own runners, with their specific platforms, build
configuration and tests.
b) bring awareness to the differences between upstream QEMU and the
version available under CentOS Stream, which is "A preview of
upcoming Red Hat Enterprise Linux minor and major releases".
c) because of b), it should be easier to identify and reduce the gap
between Red Hat's downstream and upstream QEMU.
The components of this custom job are:
I) OS build environment setup code:
- additions to the existing "build-environment.yml" playbook
that can be used to set up CentOS/EL 8 systems.
- a CentOS Stream 8 specific "build-environment.yml" playbook
that adds to the generic one.
II) QEMU build configuration: a script that will produce binaries with
features as similar as possible to the ones built and packaged on
CentOS stream 8.
III) Scripts that define the minimum amount of testing that the
binaries built with the given configuration (point II) under the
given OS build environment (point I) should be subjected to.
IV) Job definition: GitLab CI jobs that will dispatch the build/test
jobs (see points #II and #III) to the machine specifically
configured according to #I.

file-posix: Fix alignment after reopen changing O_DIRECT
At the end of a reopen, we already call bdrv_refresh_limits(), which
should update bs->request_alignment according to the new file
descriptor. However, raw_probe_alignment() relies on s->needs_alignment
and just uses 1 if it isn't set. We neglected to update this field, so
starting with cache=writeback and then reopening with cache=none means
that we get an incorrect bs->request_alignment == 1 and unaligned
requests fail instead of being automatically aligned.
Fix this by recalculating s->needs_alignment in raw_refresh_limits()
before calling raw_probe_alignment().

block: Let replace_child_noperm free children
In most of the block layer, especially when traversing down from other
BlockDriverStates, we assume that BdrvChild.bs can never be NULL. When
it becomes NULL, it is expected that the corresponding BdrvChild pointer
also becomes NULL and the BdrvChild object is freed.
Therefore, once bdrv_replace_child_noperm() sets the BdrvChild.bs
pointer to NULL, it should also immediately set the corresponding
BdrvChild pointer (like bs->file or bs->backing) to NULL.
In that context, it also makes sense for this function to free the
child. Sometimes we cannot do so, though, because it is called in a
transactional context where the caller might still want to reinstate the
child in the abort branch (and free it only on commit), so this behavior
has to remain optional.
In bdrv_replace_child_tran()'s abort handler, we now rely on the fact
that the BdrvChild passed to bdrv_replace_child_tran() must have had a
non-NULL .bs pointer initially. Make a note of that and assert it.

block: Let replace_child_tran keep indirect pointer
As of a future commit, bdrv_replace_child_noperm() will clear the
indirect BdrvChild pointer passed to it if the new child BDS is NULL.
bdrv_replace_child_tran() will want to let it do that, but revert this
change in its abort handler. For that, we need to have it receive a
BdrvChild ** pointer, too, and keep it stored in the
BdrvReplaceChildState object that we attach to the transaction.
Note that we do not need to store it in the BdrvReplaceChildState when
new_bs is not NULL, because then there is nothing to revert. This is
important so that bdrv_replace_node_noperm() can pass a pointer to a
loop-local variable to bdrv_replace_child_tran() without worrying that
this pointer will outlive one loop iteration.
(Of course, for that to work, bdrv_replace_node_noperm() and in turn
bdrv_replace_node() and its relatives may not be called with a NULL @to
node. Luckily, they already are not, but now we should assert this.)
bdrv_remove_file_or_backing_child() on the other hand needs to ensure
that the indirect pointer it passes will stay valid for the duration of
the transaction. Ensure this by keeping a strong reference to the BDS
whose &bs->backing or &bs->file it passes to bdrv_replace_child_tran(),
and giving up that reference only in the transaction .clean() handler.

transactions: Invoke clean() after everything else
Invoke the transaction drivers' .clean() methods only after all
.commit() or .abort() handlers are done.
This makes it easier to have nested transactions where the top-level
transactions pass objects to lower transactions that the latter can
still use throughout their commit/abort phases, while the top-level
transaction keeps a reference that is released in its .clean() method.
(Before this commit, that is also possible, but the top-level
transaction would need to take care to invoke tran_add() before the
lower-level transaction does. This commit makes the ordering
irrelevant, which is just a bit nicer.)

hw/intc/arm_gicv3: Support multiple redistributor regions
Our GICv3 QOM interface includes an array property
redist-region-count which allows board models to specify that the
registributor registers are not in a single contiguous range, but
split into multiple pieces. We implemented this for KVM, but
currently the TCG GICv3 model insists that there is only one region.
You can see the limit being hit with a setup like:
qemu-system-aarch64 -machine virt,gic-version=3 -smp 124
Add support for split regions to the TCG GICv3. To do this we switch
from allocating a simple array of MemoryRegions to an array of
GICv3RedistRegion structs so that we can use the GICv3RedistRegion as
the opaque pointer in the MemoryRegion read/write callbacks. Each
GICv3RedistRegion contains the MemoryRegion, a backpointer allowing
the read/write callback to get hold of the GICv3State, and an index
which allows us to calculate which CPU's redistributor is being
accessed.
Note that arm_gicv3_kvm always passes in NULL as the ops argument
to gicv3_init_irqs_and_mmio(), so the only MemoryRegion read/write
callbacks we need to update to handle this new scheme are the
gicv3_redist_read/write functions used by the emulated GICv3.

supposed to be set to 1 if this is the last redistributor in a series
of contiguous redistributor pages. Currently we set Last only for
the redistributor for CPU (num_cpu - 1). This only works if there is
a single redistributor region; if there are multiple redistributor
regions then we need to set the Last bit for the last redistributor
in each region.
This doesn't cause any problems currently because only the KVM GICv3
supports multiple redistributor regions, and it ignores the value in
GICv3State::gicr_typer. But we need to fix this before we can enable

The GICv3 devices have an array property redist-region-count.
Currently we check this for errors (bad values) in
gicv3_init_irqs_and_mmio(), just before we use it. Move this error
checking to the arm_gicv3_common_realize() function, where we
sanity-check all of the other base-class properties. (This will
always be before gicv3_init_irqs_and_mmio() is called, because
that function is called in the subclass realize methods, after
they have called the parent-class realize.)
The motivation for this refactor is:
* we would like to use the redist_region_count[] values in
arm_gicv3_common_realize() in a subsequent patch, so we need
to have already done the sanity-checking first
* this removes the only use of the Error** argument to

There are two ways to enable ACPI PCI Hot-plug:
* Disable the Hot-plug Capable bit on PCIe slots.
This was the first approach which led to regression [1-2], as
I/O space for a port is allocated only when it is hot-pluggable,
which is determined by HPC bit.
* Leave the HPC bit on and disable PCIe Native Hot-plug in _OSC
method.
This removes the (future) ability of hot-plugging switches with PCIe
Native hotplug since ACPI PCI Hot-plug only works with cold-plugged
bridges. If the user wants to explicitely use this feature, they can
disable ACPI PCI Hot-plug with:
--global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off
Change the bit in _OSC method so that the OS selects ACPI PCI Hot-plug
instead of PCIe Native.

ppc/mmu_helper.c: do not truncate 'ea' in booke206_invalidate_ea_tlb()
'tlbivax' is implemented by gen_tlbivax_booke206() via
gen_helper_booke206_tlbivax(). In case the TLB needs to be flushed,
booke206_invalidate_ea_tlb() is called. All these functions, but
booke206_invalidate_ea_tlb(), uses a 64-bit effective address 'ea'.
booke206_invalidate_ea_tlb() uses an uint32_t 'ea' argument that
truncates the original 'ea' value for apparently no particular reason.
This function retrieves the tlb pointer by calling booke206_get_tlbm(),
which also uses a target_ulong address as parameter - in this case, a
truncated 'ea' address. All the surrounding logic considers the
effective TLB address as a 64 bit value, aside from the signature of
booke206_invalidate_ea_tlb().
Last but not the least, PowerISA 2.07B section 6.11.4.9 [2] makes it
clear that the effective address "EA" is a 64 bit value.
Commit
01662f3e5133 introduced this code and no changes were made ever
since. An user detected a problem with tlbivax [1] stating that this
address truncation was the cause. This same behavior might be the source
of several subtle bugs that were never caught.
For all these reasons, this patch assumes that this address truncation
is the result of a mistake/oversight of the original commit, and changes
booke206_invalidate_ea_tlb() 'ea' argument to 'vaddr'.

vhost: Fix last vq queue index of devices with no cvq
The -1 assumes that cvq device model is accounted in data_queue_pairs,
if cvq does not exists, but it's actually the opposite: Devices with
!cvq are ok but devices with cvq does not add the last queue to
data_queue_pairs.
This is not a problem to vhost-net, but it is to vhost-vdpa:
* Devices with cvq gets initialized at last data vq device model, not
at cvq one.
* Devices with !cvq never gets initialized, since last_index is the
first queue of the last device model.
Because of that, the right change in last_index is to actually add the
cvq, not to remove the missing one.
This is not a problem to vhost-net, but it is to vhost-vdpa, which
device model trust to reach the last index to finish starting the
device.
Also, as the previous commit, rename it to index_end.
Tested with vp_vdpa with host's vhost=on and vhost=off, with ctrl_vq=on

sgx: Reset the vEPC regions during VM reboot
For bare-metal SGX on real hardware, the hardware provides guarantees
SGX state at reboot. For instance, all pages start out uninitialized.
The vepc driver provides a similar guarantee today for freshly-opened
vepc instances, but guests such as Windows expect all pages to be in
uninitialized state on startup, including after every guest reboot.
Qemu can invoke the ioctl to bring its vEPC pages back to uninitialized
state. There is a possibility that some pages fail to be removed if they
are SECS pages, and the child and SECS pages could be in separate vEPC
regions. Therefore, the ioctl returns the number of EREMOVE failures,
telling Qemu to try the ioctl again after it's done with all vEPC regions.

spapr_numa.c: fix FORM1 distance-less nodes
Commit
71e6fae3a99 fixed an issue with FORM2 affinity guests with NUMA
nodes in which the distance info is absent in
machine_state->numa_state->nodes. This happens when QEMU adds a default
NUMA node and when the user adds NUMA nodes without specifying the
distances.
During the discussions of the forementioned patch [1] it was found that
FORM1 guests were behaving in a strange way in the same scenario, with
the kernel seeing the distances between the nodes as '160', as we can
see in this example with 4 NUMA nodes without distance information:
$ numactl -H
available: 4 nodes (0-3)
(...)
node distances:
node 0 1 2 3
0: 10 160 160 160
1: 160 10 160 160
2: 160 160 10 160
3: 160 160 160 10
Turns out that we have the same problem with FORM1 guests - we are
calculating associativity domain using zeroed values. And as it also
turns out, the solution from
71e6fae3a99 applies to FORM1 as well.
This patch creates a wrapper called 'get_numa_distance' that contains
the logic used in FORM2 to define node distances when this information
is absent. This helper is then used in all places where we need to read
distance information from machine_state->numa_state->nodes. That way
we'll guarantee that the NUMA node distance is always being curated
before being used.
After this patch, the FORM1 guest mentioned above will have the
following topology:
$ numactl -H
available: 4 nodes (0-3)
(...)
node distances:
node 0 1 2 3
0: 10 20 20 20
1: 20 10 20 20
2: 20 20 10 20
3: 20 20 20 10
This is compatible with what FORM2 guests and other archs do in this
case.

accel/tcg: Register a force_rcu notifier
A TCG vCPU doing a busy loop systematicaly hangs the QEMU monitor
if the user passes 'device_add' without argument. This is because
drain_cpu_all() which is called from qmp_device_add() cannot return
if readers don't exit read-side critical sections. That is typically
what busy-looping TCG vCPUs do:
int cpu_exec(CPUState *cpu)
{
[...]
rcu_read_lock();
[...]
while (!cpu_handle_exception(cpu, &ret)) {
// Busy loop keeps vCPU here
}
[...]
rcu_read_unlock();
return ret;
}
For MTTCG, have all vCPU threads register a force_rcu notifier that will
kick them out of the loop using async_run_on_cpu(). The notifier is called
with the rcu_registry_lock mutex held, using async_run_on_cpu() ensures
there are no deadlocks.
For RR, a single thread runs all vCPUs. Just register a single notifier
that kicks the current vCPU to the next one.

rcu: Introduce force_rcu notifier
The drain_rcu_call() function can be blocked as long as an RCU reader
stays in a read-side critical section. This is typically what happens
when a TCG vCPU is executing a busy loop. It can deadlock the QEMU
monitor as reported in https://gitlab.com/qemu-project/qemu/-/issues/650 .
This can be avoided by allowing drain_rcu_call() to enforce an RCU grace
period. Since each reader might need to do specific actions to end a
read-side critical section, do it with notifiers.
Prepare ground for this by adding a notifier list to the RCU reader
struct and use it in wait_for_readers() if drain_rcu_call() is in
progress. An API is added for readers to register their notifiers.
This is largely based on a draft from Paolo Bonzini.

documented for device_del). It's actually either an absolute QOM

path is a device ID when it doesn't contain a slash. When it does,
the function now always fails. Broke iotest 200, which uses relative
path "vda/virtio-backend".
It fails because object_resolve_path_component() resolves just one
component, not a relative path.
The obvious function to resolve relative paths is
object_resolve_path(). It picks a parent automatically. Too much

object_resolve_path_at() for that, and use it in find_device_state().

qapi: deprecate drive-backup
Modern way is using blockdev-add + blockdev-backup, which provides a
lot more control on how target is opened.
As example of drive-backup problems consider the following:
User of drive-backup expects that target will be opened in the same
cache and aio mode as source. Corresponding logic is in
drive_backup_prepare(), where we take bs->open_flags of source.
It works rather bad if source was added by blockdev-add. Assume source
is qcow2 image. On blockdev-add we should specify aio and cache options
for file child of qcow2 node. What happens next:
drive_backup_prepare() looks at bs->open_flags of qcow2 source node.
But there no BDRV_O_NOCAHE neither BDRV_O_NATIVE_AIO: BDRV_O_NOCAHE is
places in bs->file->bs->open_flags, and BDRV_O_NATIVE_AIO is nowhere,
as file-posix parse options and simply set s->use_linux_aio.
The documentation is updated in a minimal way, so that drive-backup is
noted only as a deprecated command, and blockdev-backup used in most of
places.

Apart from that, this patchset is mostly a lot of updates to TCG

A configuration that specifies multiple nodes without distance info

a node distance is smaller than the local distance.

target/ppc, hw/ppc: Change maintainers
As our day jobs and interests have moved onto other things, Greg and I have
been struggling to keep on top of maintainership of target/ppc and
associated pieces like the pseries and powernv machine types, with their
platform specific devices.
We've therefore discussed and plan to transfer maintainership to Cédric Le
Goater (primary) and Daniel Henrique Barboza (backup). Cédric and Daniel
have been actively contributing to the area for some time, and they're
supported in this by their current employer, IBM, who has an obvious
interest in the platform.
Greg and I do plan to stay around in some capacity for at least the next
6 months, providing reviews and advice to assist the new maintainers into
the role.
