      pc-bios/s390: add s390-netboot.img · 6c5359e1
      由 Christian Borntraeger 提交于 
      It's already possible to do a network boot of an s390x guest with an
external netboot image based on a Linux installation, but it would
be much more convenient if the s390-ccw firmware supported network
booting right out of the box, without the need to assemble such an
external image first.

This is an s390-netboot.img that can be used for network booting.
You can download a combined kernel + initrd image via TFTP
by starting QEMU for example with:

 qemu-system-s390x ... -device virtio-net,netdev=n1,bootindex=1 \
       -netdev user,id=n1,tftp=/path/to/tftp,bootfile=kernel.img

Note that this version does not support downloading via config
files (i.e. pxelinux config files or .INS config files) yet. This
will be added later.

      vhost-user-scsi: Introduce a vhost-user-scsi sample application · 49cc0340
      由 Felipe Franciosi 提交于 
      This commit introduces a vhost-user-scsi backend sample application. It
must be linked with libiscsi and libvhost-user.

To use it, compile with:
  $ make vhost-user-scsi

And run as follows:
  $ ./vhost-user-scsi -u vus.sock -i iscsi://uri_to_target/
  $ qemu-system-x86_64 --enable-kvm -m 512 \
      -object memory-backend-file,id=mem,size=512m,share=on,mem-path=guestmem \
      -numa node,memdev=mem \
      -chardev socket,id=vhost-user-scsi,path=vus.sock \
      -device vhost-user-scsi-pci,chardev=vhost-user-scsi \

The application is currently limited at one LUN only and it processes
requests synchronously (therefore only achieving QD1). The purpose of
the code is to show how a backend can be implemented and to test the
vhost-user-scsi Qemu implementation.

If a different instance of this vhost-user-scsi application is executed
at a remote host, a VM can be live migrated to such a host.

      Makefile: Do not generate files if "configure" has not been run yet · 428952cf
      由 Thomas Huth 提交于 
      When doing a "make -j10" in the vanilla QEMU source tree (without
running "configure" first), the Makefile currently generates two
files already, qemu-version.h and qemu-options.def. This should not
happen, so let's only build the generated files if config-host.mak
is available (i.e. "configure" has been run already).

Put all trace.o into libqemuutil.a that the linker would only pull in .o

      Makefile: avoid leaving the temporary QEMU_PKGVERSION header file · d9e73d32
      由 Lin Ma 提交于 
      By commit 67a1de0d, When we perform 'git pull && make && sudo make install',
In 'make' stage a qemu-version.h.tmp will be generated. If the content of
qemu-version.h.tmp and qemu-version.h aren't consistent, The qemu-version.h.tmp
will be renamed to qemu-version.h. Because of the target FORCE, The same action
will be do again in 'make install' stage.

In 'make install' stage, If there is no qemu-version.h.tmp exists and we run
'make install' with sudo, The owner and group of new qemu-version.h.tmp will be
privileged user/group. When we run 'make' next time, qemu-version.h.tmp can't
be overwritten because of permission issue.

This patch removed qemu-version.h.tmp after build to fix this issue.

      contrib: add libvhost-user · 7b2e5c65
      由 Marc-André Lureau 提交于 
      Add a library to help implementing vhost-user backend (or slave).

Dealing with vhost-user as an application developer isn't so easy: you
have all the trouble with any protocol: validation, unix ancillary data,
shared memory, eventfd, logging, and on top of that you need to deal
with virtio queues, if possible efficiently.

qemu test has a nice vhost-user testing application vhost-user-bridge,
which implements most of vhost-user, and virtio.c which implements
virtqueues manipulation. Based on these two, I tried to make a simple
library, reusable for tests or development of new vhost-user scenarios.

      rules.mak: quiet-command: Split command name and args to print · 0bdb12c7
      由 Peter Maydell 提交于 
      The quiet-command make rule currently takes two arguments:
the command and arguments to run, and a string to print if
the V flag is not set (ie we are not being verbose).
By convention, the string printed is of the form
"  NAME   some args". Unfortunately to get nicely lined up
output all the strings have to agree about what column the
arguments should start in, which means that if we add a
new quiet-command usage which wants a slightly longer CMD
name then we either put up with misalignment or change
every quiet-command string.

Split the quiet-mode string into two, the "NAME" and
the "same args" part, and use printf(1) to format the
string automatically. This means we only need to change
one place if we want to support a longer maximum name.

In particular, we can now print 7-character names lined
up properly (they are needed for the OSX "SETTOOL" invocation).

Change all the uses of quiet-command to the new syntax.
(Any which are missed or inadvertently reintroduced
via later merges will result in slightly misformatted
quiet output rather than disaster.)

A few places in the pc-bios/ makefiles are updated to use
"BUILD", "SIGN" and "STRIP" rather than "Building",
"Signing" and "Stripping" for consistency and to keep them
below 7 characters. Module .mo links now print "LD" rather
than the nonstandard "LD -r".

      blockdev: Add dynamic module loading for block drivers · 88d88798
      由 Marc Mari 提交于 
      Extend the current module interface to allow for block drivers to be
loaded dynamically on request. The only block drivers that can be
converted into modules are the drivers that don't perform any init
operation except for registering themselves.

In addition, only the protocol drivers are being modularized, as they
are the only ones which see significant performance benefits. The format
drivers do not generally link to external libraries, so modularizing
them is of no benefit from a performance perspective.

All the necessary module information is located in a new structure found
in module_block.h

This spoils the purpose of 5505e8b7 (block/dmg: make it modular).

Before this patch, if module build is enabled, block-dmg.so is linked to
libbz2, whereas the main binary is not. In downstream, theoretically, it
means only the qemu-block-extra package depends on libbz2, while the
main QEMU package needn't to. With this patch, we (temporarily) change
the case so that the main QEMU depends on libbz2 again.
