This is the very basic/initial version of virtio-mem. An introduction to
virtio-mem can be found in the Linux kernel driver [1]. While it can be
used in the current state for hotplug of a smaller amount of memory, it
will heavily benefit from resizeable memory regions in the future.
Each virtio-mem device manages a memory region (provided via a memory
backend). After requested by the hypervisor ("requested-size"), the
guest can try to plug/unplug blocks of memory within that region, in order
to reach the requested size. Initially, and after a reboot, all memory is
unplugged (except in special cases - reboot during postcopy).
The guest may only try to plug/unplug blocks of memory within the usable
region size. The usable region size is a little bigger than the
requested size, to give the device driver some flexibility. The usable
region size will only grow, except on reboots or when all memory is
requested to get unplugged. The guest can never plug more memory than
requested. Unplugged memory will get zapped/discarded, similar to in a
balloon device.
The block size is variable, however, it is always chosen in a way such that
THP splits are avoided (e.g., 2MB). The state of each block
(plugged/unplugged) is tracked in a bitmap.
As virtio-mem devices (e.g., virtio-mem-pci) will be memory devices, we now
expose "VirtioMEMDeviceInfo" via "query-memory-devices".
--------------------------------------------------------------------------
There are two important follow-up items that are in the works:
1. Resizeable memory regions: Use resizeable allocations/RAM blocks to
grow/shrink along with the usable region size. This avoids creating
initially very big VMAs, RAM blocks, and KVM slots.
2. Protection of unplugged memory: Make sure the gust cannot actually
make use of unplugged memory.
Other follow-up items that are in the works:
1. Exclude unplugged memory during migration (via precopy notifier).
2. Handle remapping of memory.
3. Support for other architectures.
--------------------------------------------------------------------------
Example usage (virtio-mem-pci is introduced in follow-up patches):
Start QEMU with two virtio-mem devices (one per NUMA node):
$ qemu-system-x86_64 -m 4G,maxmem=20G \
-smp sockets=2,cores=2 \
-numa node,nodeid=0,cpus=0-1 -numa node,nodeid=1,cpus=2-3 \
[...]
-object memory-backend-ram,id=mem0,size=8G \
-device virtio-mem-pci,id=vm0,memdev=mem0,node=0,requested-size=0M \
-object memory-backend-ram,id=mem1,size=8G \
-device virtio-mem-pci,id=vm1,memdev=mem1,node=1,requested-size=1G
Query the configuration:
(qemu) info memory-devices
Memory device [virtio-mem]: "vm0"
memaddr: 0x140000000
node: 0
requested-size: 0
size: 0

Add some memory to node 0:

The atomic_cmpxchg() loop is broken because we occasionally end up with
old and _old having different values (a legit compiler can generate code
that accessed *ind_addr again to pick up a value for _old instead of
using the value of old that was already fetched according to the
rules of the abstract machine). This means the underlying CS instruction
may use a different old (_old) than the one we intended to use if
atomic_cmpxchg() performed the xchg part.
Let us use volatile to force the rules of the abstract machine for
accesses to *ind_addr. Let us also rewrite the loop so, we that the
new old is used to compute the new desired value if the xchg part
is not performed.

Waiting on a process for which we have a pipe will stall if the process
outputs more data than fits into the OS-provided buffer. We must use
communicate() before wait(), and in fact, communicate() perfectly
replaces wait() already.
We have to drop the stderr=subprocess.STDOUT parameter from
subprocess.Popen() in qemu_nbd_early_pipe(), because stderr is passed on
to the child process, so if we do not drop this parameter, communicate()
will hang (because the pipe is not closed).

array_remove_slice() calls array_roll() with array->next - 1 as the
destination index. This is only correct for count == 1, otherwise we're
writing past the end of the array. array->next - count would be correct.
However, this is the only place ever calling array_roll(), so this
rather complicated operation isn't even necessary.
Fix the problem and simplify the code by replacing it with a single
memmove() call. array_roll() can now be removed.

FAT allows only a restricted set of characters in file names, and for
some of the illegal characters, it's actually important that we catch
them: If filenames can contain '/', the guest can construct filenames
containing "../" and escape from the assigned vvfat directory. The same
problem could arise if ".." was ever accepted as a literal filename.
Fix this by adding a check that all filenames are valid in
check_directory_consistency().

Since commit 5a37b60a61, qemu-img create will pre-zero the target image
if it isn't already zero-initialised (most importantly, for host block
devices, but also iscsi etc.), so that writing explicit zeros wouldn't
be necessary later.
This could speed up the operation significantly, in particular when the
source image file was only sparsely populated. However, it also means
that some block are written twice: Once when pre-zeroing them, and then
when they are overwritten with actual data. On a full image, the
pre-zeroing is wasted work because everything will be overwritten.
In practice, write_zeroes typically turns out faster than writing
explicit zero buffers, but slow enough that first zeroing everything and
then overwriting parts can be a significant net loss.
Meanwhile, qemu-img convert was rewritten in 690c730160 and zero blocks
are now written to the target using bdrv_co_pwrite_zeroes() if the
target could be pre-zeroed. This way we already make use of the faster
write_zeroes operation, but avoid writing any blocks twice.
Remove the pre-zeroing because these days this former optimisation has
actually turned into a pessimisation in the common case.

Vector extension is default off. The only way to use vector extension is
1. use cpu rv32 or rv64
2. turn on it by command line
"-cpu rv64,x-v=true,vlen=128,elen=64,vext_spec=v0.7.1".
vlen is the vector register length, default value is 128 bit.
elen is the max operator size in bits, default value is 64 bit.
vext_spec is the vector specification version, default value is v0.7.1.
These properties can be specified with other values.
