For HPC usage case, it will create a huge VM with vcpus number as same as host
cpus and this requires more vcpus support in a single VM. This patch is to
increase max vcpu number from 288 to 8192 which is current default maximum cpu
number for Linux kernel.

The s390-ipl device can not be created by the user, since it is meant only
to be instantiated once internally to load the ROMs and kernel. If the user
tries to do a "device_add s390-ipl" via the monitor later, QEMU aborts with
a "ROM images must be loaded at startup" error message.

Hi,
I recently noticed that QEMU abort()s if you try to remove the diag288

This patch is a follow up on the discussions that started with
Laurent's patch series "spapr: disable hotplugging without OS" [1]
and discussions made at patch "spapr: reset DRCs on migration
pre_load" [2].
At this moment, we do not support CPU/memory hotplug in early
boot stages, before CAS. The
Both io and memory use the same mmio functions in the rtl8139 device.
This patch removes the separate MemoryRegionOps and old_mmio accessors
for memory, and replaces it with an alias to the io memory region.

Acording to the ARM ARM exclusive loads require the same allignment as
exclusive stores. Let's update the memops used for the load to match
that of the store. This adds the alignment requirement to the memops.
PCIe busses are always little endian, so set the endianness of the
memory region to little endian rather than native such that operations
work as expected on big endian targets.

The "inactive" state of BDS affects whether the permissions can be
granted, we must call bdrv_invalidate_cache before bdrv_set_perm to
support "-incoming defer" case.

As in the case of nbd_export_new(), bdrv_invalidate_cache() can be
called when migration is still in progress. In this case we are not
ready to tighten the shared permissions fenced by blk->disable_perm.
Defer to a VM state change handler.

When we switched NBD to use coroutines for qemu 2.9 (in particular,
commit a12a712a), we introduced a regression: if a server sends us
garbage (such as a corrupted magic number), we quit the read loop
but do not stop sending further queued commands, resulting in the
client hanging when it never rea
NBD_CMD_DISC is a disconnect request, not a data discard request.

The 093 throttling test submits twice as many requests as the throttle
limit in order to ensure that we reach the limit. The remaining
requests are left in-flight at the end of each test iteration.

Acording to the ARM ARM exclusive loads require the same allignment as
exclusive stores. Let's update the memops used for the load to match
that of the store. This adds the alignment requirement to the memops.

When we perform the atomic_cmpxchg operation we want to perform the
operation on a pair of 32-bit registers. Previously we were just passing
the register size in which was set to MO_32. This would result in the
high register to be ignored. To fix this issue we hardcode the
We are not providing the required single-copy atomic semantics for
the 64-bit operation that is the 32-bit paired load.
At the same time, leave the entire 64-bit value in cpu_exclusive_val
and stop writing to cpu_exclusive_high. This means that we do not
have to re-assemble the 64-bit quantity wh
In reviewing my previous patch, Peter pointed out that it is
CONSTRAINED UNPREDICTABLE what happens when you mix the number
of registers in a LDX[PR] + STX[RP] pair. So most of the bug
that I thought that I was fixing isn't a bug at all.
That said, the patch does still fix a real bug wrt single-c

The mmio-interface device is not something we want to allow
