      hw: include hw header files with full paths · 83c9f4ca
      由 Paolo Bonzini 提交于 
      Done with this script:

cd hw
for i in `find . -name '*.h' | sed 's/^..//'`; do
  echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,'
done | sed -i -f - `find . -type f`

This is so that paths remain valid as files are moved.

Instead, files in hw/dataplane are referenced with the relative path.
We know they are not going to move to include/, and they are the only
include files that are in subdirectories _and_ move.

      hw: move qdev-monitor.o to toplevel directory · b4a42f81
      由 Paolo Bonzini 提交于 
      qdev-monitor.c is the only "core qdev" file that is not used in
user-mode emulation, and it does not define anything that is used
by hardware models.  Remove it from the hw/ directory and
remove hw/qdev-monitor.h from hw/qdev.h too; this requires
some files to have some new explicitly includes.

      virtio-scsi: Fix subtle (guest) endian bug · 863d1050
      由 David Gibson 提交于 
      The virtio-scsi config space is, by specification, in guest endian (which
is ill-defined, but there you go).  In virtio_scsi_get_config() we set up
all the fields in there, using stl_raw().  Which is a problem for the
max_channel and max_target fields, which are 16-bit, not 32-bit.  For
little-endian targets we get away with it by accident, since the first
two bytes will still be correct, and the extra two bytes written (with
zeroes) will be overwritten correctly by the next store.

But for big-endian guests, this means the max_target field ends up as zero,
which means the guest will only recognize a single disk on the virtio-scsi
bus.  This patch fixes the problem.

      virtio-scsi: Fix some endian bugs with virtio-scsi · 474ee55a
      由 David Gibson 提交于 
      The virtio-scsi specification does not specify the correct endianness for
fields in the request structure.  It's therefore best to assume that it is
"guest native" endian since that's the (stupid and poorly defined) norm in
virtio.

However, the qemu device for virtio-scsi has no byteswaps at all, and so
will break if the guest has different endianness from the host.  This patch
fixes it by adding tswap() calls for the sense_len and resid fields in
the request structure.  In theory status_qualifier needs swaps as well,
but that field is never actually touched.  The tag field is a uint64_t, but
since its value is completely arbitrary, it might as well be uint8_t[8]
and so it does not need swapping.

      Rename target_phys_addr_t to hwaddr · a8170e5e
      由 Avi Kivity 提交于 
      target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific).  Replace it with a finger-friendly,
standards conformant hwaddr.

Outstanding patchsets can be fixed up with the command

  git rebase -i --exec 'find -name "*.[ch]"

      virtio-scsi: do not compare 32-bit QEMU tags against 64-bit virtio-scsi tags · 4dd7c82c
      由 Paolo Bonzini 提交于 
      This patch fixes a problem in handling task management functions
in virtio-scsi.  The cause of the problem is a mismatch between
the size of the tag in QEMU (32-bit) and virtio-scsi (64-bit).
Changing the QEMU size is hard because the migration format
uses 32 bits to store the tag; so just don't use the QEMU tag
(virtio-scsi only uses the tag for task management functions
anyway) and look up the full 64-bit tag in the hba_private field.

The reproducer is a bit obscure.  If you cause an I/O timeout
(for example with rerror=stop and doing 'cont' on the monitor
continuously without fixing the error), sooner or later the
guest will try to abort the command and reissue it.  At this
point, QEMU will report _two_ errors instead of one when you
hit 'c', because the first error has not been canceled correctly.
