b98a3bae25 Makefile: use $(MAKE) variable
For some systems (i.e. FreeBSD) the default 'make' is not compatible with the
GNU extensions used by QEMU makefiles.

Calling the GNU make (gmake) works, however the help displayed refers to the
host 'make' and copy/paste leads to lot of unobvious errors:

  $ gmake check-help
  [...]
   make check                Run all tests

  $ make check
  make: "Makefile" line 28: Missing dependency operator
  make: "Makefile" line 37: Need an operator
  make: "Makefile" line 41: warning: duplicate script for target "git-submodule-update" ignored
  make: "rules.mak" line 70: warning: duplicate script for target "%.o" ignored
  make: Unknown modifier ' '
  make: Unclosed substitution for eval modules (= missing)
  make: "tests/Makefile.include" line 24: Variable/Value missing from "export"
  make: "tests/" line 1: warning: Zero byte read from file, skipping rest of line.
  make: "tests/" line 1: Need an operator
  make: "Makefile" line 660: warning: duplicate script for target "ifneq" ignored
  make: "Makefile" line 78: warning: using previous script for "ifneq" defined here
  make: Fatal errors encountered -- cannot continue

Using the $(MAKE) variable, the help displayed is consistent with the 'make'
program used.

7c3d1917fd build: disarm the TCG unit test trap
Developers sometimes mistakenly run 'make test' instead of 'make check'.
'make test' triggers the ancient, unmaintained tcg unit tests in
tests/tcg/Makefile which have long since ceased compiling.

Even if someone fixes the TCG tests, it makes little sense to put
them in a 'make test' target, rather they should be 'make check-tcg',
possibly wired up as a dependency of 'make check'.

In the meantime, this patch disarms the 'make test' trap by simply
deleting it so users get an immediate error. This should be enough
for them to remember to type 'make check' instead (or 'make help'
to learn). It also deletes 'make speed' which is another route
into the tcg tests.

b8e535ae8a Makefile: simpler/faster "make help"
Using obscure black magic introduced in eaa2ddbb76 :)

In an out-of-tree directory, running "../configure && make help" will generate
some required files (.mak), then clone some submodules, compile at least
the capstone submodule, generate QMP and Trace files, and finally display
the help.

On an outdated computer (Sun Blade workstation), running "make help" took
more than 5h :) With this patch it took roughly 37min.

c4b01c7c51 build: remove use of MAKELEVEL optimization in submodule handling
The Makefile attempts to optimize the handling of submodules by using MAKELEVEL
to only check the submodule status when running from the top level make
invokation. This causes problems for people who are using a makefile of their
own to in turn invoke QEMU's makefile, as MAKELEVEL is already set to 1 (or
more) when QEMU's makefile runs.

This optimization should not really be needed, since the git-submodule.sh
script is already used to detect if a submodule update is required. This by
removing the MAKELEVEL check, we at most add an extra 'git-submodule.sh status'
call to each make level, the overhead of which is lost in noise of building
QEMU.

f62bbee55d build: allow automatic git submodule updates to be disabled
Some people building QEMU use VPATH builds where the source directory is on a
read-only volume. In such a case 'scripts/git-submodules.sh update' will always
fail and users are required to run it manually themselves on their original
writable source directory.

While this is already supported, it is nice to give users a command line flag
to configure to permanently disable automatic submodule updates, as it means
they won't get hard to diagnose failures from git-submodules.sh at an arbitrary
later date.

This patch thus introduces a flag '--disable-git-update' which will prevent
'make' from ever running 'scripts/git-submodules.sh update'. It will still run
the 'status' command to determine if a submodule update is needed, but when it
does this it'll simply stop and print a message instructing the developer what
todo. eg

$ ./configure  --target-list=x86_64-softmmu --disable-git-update
...snip...

Some users can't run a bare 'git' command, due to need for a transparent
proxying solution such as 'tsocks'. This adds an argument to configure to
let users specify such a thing:

  ./configure --with-git="tsocks git"

The submodule script is also updated to give the user a hint about using this
flag, if we fail to checkout modules.

This was introduced by:
    commit aef45d51d1

    Date:   Fri Sep 29 11:11:56 2017 +0100

	build: automatically handle GIT submodule checkout for dtc

On my system, I see the following with a fresh clone:

% ./configure --disable-gtk --target-list=aarch64-softmmu
% make -j8
  GEN     aarch64-softmmu/config-devices.mak.tmp
  GEN     config-host.h

  GEN     qemu-options.def
[snip]
  GEN     migration/trace.h
make: *** [git-submodule-update] Error 1
make: *** Waiting for unfinished jobs....

Upon closer inspection, the root cause of the error is:

% git submodule update --init ui/keycodemapdb dtc
fatal: destination path 'dtc' already exists and is not an empty directory.
Clone of 'git://git.qemu-project.org/dtc.git' into submodule path 'dtc' failed

This patch fixes this race condition by forcing the 'dtc/%' rule which caused
'dtc' to be non-empty to wait on '.git-submodule-status'.

  KEY_LINEFEED -> Q_KEY_CODE_LF
  KEY_KPEQUAL -> Q_KEY_CODE_KP_EQUALS
  KEY_COMPOSE -> Q_KEY_CODE_COMPOSE
  KEY_AGAIN -> Q_KEY_CODE_AGAIN

  KEY_PASTE -> Q_KEY_CODE_PASTE
  KEY_CUT -> Q_KEY_CODE_CUT
  KEY_HELP -> Q_KEY_CODE_HELP
  KEY_MEDIA -> Q_KEY_CODE_MEDIASELECT

In addition, some fixes:

 - KEY_PLAYPAUSE now maps to Q_KEY_CODE_AUDIOPLAY, instead of
   KEY_PLAYCD. KEY_PLAYPAUSE is defined across almost all scancodes
   sets, while KEY_PLAYCD only appears in AT set1, so the former is
   a more useful mapping.

Missing entries in qcode_to_number now fixed:

  Q_KEY_CODE_AGAIN -> 0x85
  Q_KEY_CODE_PROPS -> 0x86
  Q_KEY_CODE_UNDO -> 0x87
  Q_KEY_CODE_FRONT -> 0x8c
  Q_KEY_CODE_COPY -> 0xf8
  Q_KEY_CODE_OPEN -> 0x64
  Q_KEY_CODE_PASTE -> 0x65
  Q_KEY_CODE_CUT -> 0xbc
  Q_KEY_CODE_LF -> 0x5b
  Q_KEY_CODE_HELP -> 0xf5
  Q_KEY_CODE_COMPOSE -> 0xdd
  Q_KEY_CODE_KP_EQUALS -> 0x59
  Q_KEY_CODE_MEDIASELECT -> 0xed

In addition, some fixes:

 - Q_KEY_CODE_MENU was incorrectly mapped to the compose
   scancode (0xdd) and is now mapped to 0x9e
 - Q_KEY_CODE_FIND was mapped to 0xe065 (Search) instead
   of to 0xe041 (Find)
 - Q_KEY_CODE_HIRAGANA was mapped to 0x70 (Katakanahiragana)
   instead of of 0x77 (Hirigana)
 - Q_KEY_CODE_PRINT was mapped to 0xb7 which is not a defined
   scan code in AT set 1, it is now mapped to 0x54 (sysrq)

The https://gitlab.com/keycodemap/keycodemapdb/ repo contains a
data file mapping between all the different scancode/keycode/keysym
sets that are known, and a tool to auto-generate lookup tables for
different combinations.

It is used by GTK-VNC, SPICE-GTK and libvirt for mapping keys.
Using it in QEMU will let us replace many hand written lookup
tables with auto-generated tables from a master data source,
reducing bugs. Adding new QKeyCodes will now only require the
master table to be updated, all ~20 other tables will be
automatically updated to follow.

aef45d51d1 build: automatically handle GIT submodule checkout for dtc
Currently if DTC is required by configure and not available in the host
OS install, we exit with an error message telling the user to checkout a
git submodule or install the library.

This introduces automatic handling of the git submodule checkout process
and enables it for dtc. This only runs if building from GIT, so users of
release tarballs still need the system library install. The current state
of the git checkout is stashed in .git-submodule-status, and a helper
program is used to determine if this state matches the desired submodule
state. A dependency against 'Makefile' ensures that the submodule state
is refreshed at the start of the build process

Extract the relevant part of qemu-doc.html into a new file called
docs/qemu-block-drivers.texi.  This file can also be built as a
stand-alone document (man, html, etc).

fe8fc5ae5c scsi: add multipath support to qemu-pr-helper
Proper support of persistent reservation for multipath devices requires
communication with the multipath daemon, so that the reservation is
registered and applied when a path comes up.  The device mapper
utilities provide a library to do so; this patch makes qemu-pr-helper.c
detect multipath devices and, when one is found, delegate the operation
to libmpathpersist.

b855f8d175 scsi: build qemu-pr-helper
Introduce a privileged helper to run persistent reservation commands.
This lets virtual machines send persistent reservations without using
CAP_SYS_RAWIO or out-of-tree patches.  The helper uses Unix permissions
and SCM_RIGHTS to restrict access to processes that can access its socket
and prove that they have an open file descriptor for a raw SCSI device.

The next patch will also correct the usage of persistent reservations
with multipath devices.

It would also be possible to support for Linux's IOC_PR_* ioctls in
the future, to support NVMe devices.  For now, however, only SCSI is
supported.

6c5359e161 pc-bios/s390: add s390-netboot.img
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.

49cc0340f8 vhost-user-scsi: Introduce a vhost-user-scsi sample application
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.
