hw/intc: riscv-imsic: Fix interrupt state updates.
The IMSIC state variable eistate[] is modified by CSR instructions
within a range dedicated to the local CPU and by MMIO writes from any CPU.
Access to eistate from MMIO accessors is protected by the BQL, but
read-modify-write (RMW) sequences from CSRRW do not acquire the BQL,
making the RMW sequence vulnerable to a race condition with MMIO access
from a remote CPU.
This race can manifest as missing IPI or MSI in multi-CPU systems, eg:
The interrupt line raise/lower sequence was changed to prevent a race
between the evaluation of the eistate and the execution of the qemu_irq
raise/lower, ensuring that the interrupt line is not incorrectly
deactivated based on a stale topei check result. To avoid holding BQL
all modifications of eistate are converted to atomic operations.

C doesn't extend the sign bit for unsigned types since there isn't a

physical addresses may be up to 34 bits wide, so we don't want to

the firmware entry point is what they provided for firmware_load_addr,

Pass back the ELF entry point to use when generating the boot ROM, so

While the spec doesn't state it, setting timecmp to UINT64_MAX is
another way to stop a timer, as it's considered setting the next

eventually reach UINT64_MAX, the very next tick will bring it back to
zero, once again less than timecmp. For this reason
riscv_timer_write_timecmp() special cases UINT64_MAX. However, if a
previously set timecmp has not yet expired, then setting timecmp to
UINT64_MAX to disable / stop it would not work, as the special case
left the previous QEMU timer active, which would then still deliver
an interrupt at that previous timecmp time. Ensure the stopped timer
will not still deliver an interrupt by also deleting the QEMU timer

impossible. There are only two callers:
1. block_copy_task_create()
It already asserts the very same condition before calling
reqlist_init_req().
2. cbw_snapshot_read_lock()
There is no need to have read requests be non-overlapping in
copy-before-write when used for snapshot-access. In fact, there was no
protection against two callers of cbw_snapshot_read_lock() calling
reqlist_init_req() with overlapping ranges and this could lead to an
assertion failure [1].
In particular, with the reproducer script below [0], two

backup: add minimum cluster size to performance options
In the context of backup fleecing, discarding the source will not work
when the fleecing image has a larger granularity than the one used for
block-copy operations (can happen if the backup target has smaller
cluster size), because cbw_co_pdiscard_snapshot() will align down the
discard requests and thus effectively ignore then.
To make @discard-source work in such a scenario, allow specifying the
minimum cluster size used for block-copy operations and thus in
particular also the granularity for discard requests to the source.

The type 'size' (corresponding to uint64_t in C) is used in QAPI to
rule out negative inputs and for consistency with already existing
@cluster-size parameters. Since block_copy_calculate_cluster_size()
uses int64_t for its result, a check that the input is not too large
is added in block_copy_state_new() before calling it. The calculation
in block_copy_calculate_cluster_size() is done in the target int64_t
type.

Use these to make "configure", "build" and "test" separate
collapsible stages.
As recommended by the GitLab docs, we use some shell which is
sourced in the CI job to define functions to emit the magic
lines that start and end sections, to hide the ugliness of
the printf lines from the log.

.gitlab-ci.d: Split build and test in cross build job templates
In the native_build_job_template we have separate steps in the script
for the build and the test steps. This is helpful because then
gitlab will give separate timestamps in the log view for each, and
you can see how long it took to compile vs how long to test. In the
templates in crossbuild-template.yml, however, we do both the build
and test in a single 'make' invocation, and so we don't get the
separate timing information.
Split the build and test, in the same way we do in the native build
template.
This will also give us a place to separate out how parallel we want
to do the build by default from how parallel we want to do the tests
by default, which might be helpful in future.

virtio-mem: Add support for suspend+wake-up with plugged memory
Before, the virtio-mem device would unplug all the memory with any reset
of the device, including during the wake-up of the guest from a
suspended state. Due to this, the virtio-mem driver in the Linux kernel
disallowed suspend-to-ram requests in the guest when the
VIRTIO_MEM_F_PERSISTENT_SUSPEND feature is not exposed by QEMU.
This patch adds the code to skip the reset on wake-up and exposes
theVIRTIO_MEM_F_PERSISTENT_SUSPEND feature to the guest kernel driver
when suspending is possible in QEMU (currently only x86).

reset: Use ResetType for qemu_devices_reset() and MachineClass::reset()
Currently, both qemu_devices_reset() and MachineClass::reset() use
ShutdownCause for the reason of the reset. However, the Resettable
interface uses ResetState, so ShutdownCause needs to be translated to
ResetType somewhere. Translating it qemu_devices_reset() makes adding
new reset types harder, as they cannot always be matched to a single
ShutdownCause here, and devices may need to check the ResetType to
determine what to reset and if to reset at all.
This patch moves this translation up in the call stack to
qemu_system_reset() and updates all MachineClass children to use the
ResetType instead.

virtio: kconfig: memory devices are PCI only
Virtio memory devices rely on PCI BARs to expose the contents of memory.
Because of this they cannot be used (yet) with virtio-mmio or virtio-ccw.
In fact the code that is common to virtio-mem and virtio-pmem, which
is in hw/virtio/virtio-md-pci.c, is only included if CONFIG_VIRTIO_PCI
is set. Reproduce the same condition in the Kconfig file, only allowing
VIRTIO_MEM and VIRTIO_PMEM to be defined if the transport supports it.
Without this patch it is possible to create a configuration with
CONFIG_VIRTIO_PCI=n and CONFIG_VIRTIO_MEM=y, but that causes a
linking failure.
