2c3132279b 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.

dd47a8f654 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.

ef149763a8 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.

1bf4d3294b monitor: Fix find_device_state() for IDs containing slashes
Recent commit 6952026120 "monitor: Tidy up find_device_state()"
assumed the function's argument is "the device's ID or QOM path" (as
documented for device_del).  It's actually either an absolute QOM
path, or a QOM path relative to /machine/peripheral/.  Such a relative
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
magic, we want to specify the parent.  Create new
object_resolve_path_at() for that, and use it in find_device_state().

1084159b31 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.

4a778dac9e tests/qtest/virtio-net: fix hotplug test case
virtio-net-test has an hotplug testcase that is never executed.

This is because the testcase is attached to virtio-pci interface
rather than to virtio-net-pci.

if we don't reset the auto-converge counter,
it will continue to run with COLO running,
and eventually the system will hang due to the
CPU throttle reaching DEFAULT_MIGRATE_MAX_CPU_THROTTLE.

f10e7b9f6f ppc patch queue for 2021-11-09
Here's the latest set of ppc related patches for qemu-6.2, which I
 hope will squeeze in just barely before the hard freeze.
 
 This set includes a change to MAINTAINERS moving maintainership of ppc
 from myself and Greg Kurz to Cédric le Goater and Daniel Henrique
 Barboza.  So, I expect this to be my last pull request as ppc
 maintainer.  It's been great, but it's time I moved onto other things.
 
 Apart from that, this patchset is mostly a lot of updates to TCG
 implementations of ISA 3.1 (POWER10) instructions from the El Dorado
 team.  There are also a handful of other fixes.

71e6fae3a9 spapr_numa.c: FORM2 table handle nodes with no distance info
A configuration that specifies multiple nodes without distance info
results in the non-local points in the FORM2 matrix having a distance of
0. This causes Linux to complain "Invalid distance value range" because
a node distance is smaller than the local distance.

Fix this by building a simple local / remote fallback for points where
distance information is missing.

14fe3222e5 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.
