Alex Bennée a622d64eea plugins: new hwprofile plugin
This is a plugin intended to help with profiling access to various
bits of system hardware. It only really makes sense for system
emulation.

It takes advantage of the recently exposed helper API that allows us
to see the device name (memory region name) associated with a device.

You can specify arg=read or arg=write to limit the tracking to just
reads or writes (by default it does both).

The pattern option:

  -plugin ./tests/plugin/libhwprofile.so,arg=pattern

will allow you to see the access pattern to devices, eg:

  gic_cpu @ 0xffffffc010040000
    off:00000000, 8, 1, 8, 1
    off:00000000, 4, 1, 4, 1
    off:00000000, 2, 1, 2, 1
    off:00000000, 1, 1, 1, 1

The source option:

  -plugin ./tests/plugin/libhwprofile.so,arg=source

will track the virtual source address of the instruction making the
access:

  pl011 @ 0xffffffc010031000
    pc:ffffffc0104c785c, 1, 4, 0, 0
    pc:ffffffc0104c7898, 1, 4, 0, 0
    pc:ffffffc010512bcc, 2, 1867, 0, 0

You cannot mix source and pattern.

Finally the match option allow you to limit the tracking to just the
devices you care about.

Undo the damage from commit 5f9ff1eff3 ("libvhost-user: Support tracking

osdep.h inclusion.

libvhost-user.c tries to stay free from glib usage.

Use glibc memfd_create directly when available (assumed so when
MFD_ALLOW_SEALING is defined). A following commit will make the project
standalone and check for memfd API at configure time, instead of a
panic at runtime.

  } VhostUserMemoryRegion;

  typedef struct VhostUserMemRegMsg {
      uint32_t padding;
      /* WARNING: there is a 32-bit hole here! */
      VhostUserMemoryRegion region;
  } VhostUserMemRegMsg;

The payload size is calculated as follows when sending the message in
hw/virtio/vhost-user.c:

  msg->hdr.size = sizeof(msg->payload.mem_reg.padding) +
      sizeof(VhostUserMemoryRegion);

This calculation produces an incorrect result of only 36 bytes.
sizeof(VhostUserMemRegMsg) is actually 40 bytes.

The consequence of this is that the final field, mmap_offset, is
truncated. This breaks x86_64 TCG guests on s390 hosts. Other guest/host
combinations may get lucky if either of the following holds:
1. The guest memory layout does not need mmap_offset != 0.
2. The host is little-endian and mmap_offset <= 0xffffffff so the
   truncation has no effect.

Fix this by extending the existing 32-bit padding field to 64-bit. Now
the padding reflects the actual compiler padding. This can be verified
using pahole(1).

Also document the layout properly in the vhost-user specification.  The
vhost-user spec did not document the exact layout. It would be
impossible to implement the spec without looking at the QEMU source
code.

Existing vhost-user frontends and device backends continue to work after
this fix has been applied. The only change in the wire protocol is that
QEMU now sets hdr.size to 40 instead of 36. If a vhost-user
implementation has a hardcoded size check for 36 bytes, then it will
fail with new QEMUs. Both QEMU and DPDK/SPDK don't check the exact
payload size, so they continue to work.

https://mesonbuild.com/Builtin-options.html), so we have to be aware
of this when creating 50-qemu-gpu.json and
