e4439e5280 tests/qtest: device-plug-test: Reverse the usage of double/single quotes
The usage of double/single quotes in test_q35_pci_unplug_json_request()
should be reversed to work on both win32 and non-win32 platforms:

- The value of -device parameter needs to be surrounded by "" as
  Windows does not drop '' when passing it to QEMU which causes
  QEMU command line option parser failure.
- The JSON key/value pairs need to be surrounded by '' to make the
  JSON parser happy on Windows.

Fixes: a12f1a7e56 ("tests/x86: Add subtest with 'q35' machine type to device-plug-test")

b1d3095ccf tests/qtest: Support libqtest to build and run on Windows
At present the libqtest codes were written to depend on several
POSIX APIs, including fork(), kill() and waitpid(). Unfortunately
these APIs are not available on Windows.

This commit implements the corresponding functionalities using
win32 native APIs. With this change, all qtest cases can build
successfully on a Windows host, and we can start qtest testing
on Windows now.

84c662d254 tests/qtest: Use send/recv for socket communication
Socket communication in the libqtest and libqmp codes uses read()
and write() which work on any file descriptor on *nix, and sockets
in *nix are an example of a file descriptor.

However sockets on Windows do not use *nix-style file descriptors,
so read() and write() cannot be used on sockets on Windows.
Switch over to use send() and recv() instead which work on both
Windows and *nix.

0e283d845e tests/qtest/libqos/e1000e: Use e1000_regs.h
The register definitions in tests/qtest/libqos/e1000e.c had names
different from hw/net/e1000_regs.h, which made it hard to understand
what test codes corresponds to the implementation. Use
hw/net/e1000_regs.h from tests/qtest/libqos/e1000e.c to remove
these duplications.

E1000E_CTRL_EXT_TXLSFLOW is removed from E1000E_CTRL_EXT settings
because hw/net/e1000_regs.h does not have the definition and it is for
TCP segmentation offload, which does not matter for the implemented
tests.

daa8bb57db tests/qtest/tpm: Clean up remainders of swtpm
After running "make check", there are remainders of the tpm
tests left in the /tmp directory, slowly filling it up.
Seems like "swtpm" leaves a ".lock" and a "tpm2-00.permall"
file behind, so that the g_rmdir() calls on the temporary
directories fail. Introduce a helper function to remove those
leftovers before doing the g_rmdir().

5bb0474778 block: Manipulate bs->file / bs->backing pointers in .attach/.detach
bs->file and bs->backing are a kind of duplication of part of
bs->children. But very useful diplication, so let's not drop them at
all:)

We should manage bs->file and bs->backing in same place, where we
manage bs->children, to keep them in sync.

Moreover, generic io paths are unprepared to BdrvChild without a bs, so
it's double good to clear bs->file / bs->backing when we detach the
child.

Detach is simple: if we detach bs->file or bs->backing child, just
set corresponding field to NULL.

Attach is a bit more complicated. But we still can precisely detect
should we set one of bs->file / bs->backing or not:

- if role is BDRV_CHILD_COW, we definitely deal with bs->backing
- else, if role is BDRV_CHILD_FILTERED (it must be also
  BDRV_CHILD_PRIMARY), it's a filtered child. Use
  bs->drv->filtered_child_is_backing to chose the pointer field to
  modify.
- else, if role is BDRV_CHILD_PRIMARY, we deal with bs->file
- in all other cases, it's neither bs->backing nor bs->file. It's some
  other child and we shouldn't care

OK. This change brings one more good thing: we can (and should) get rid
of all indirect pointers in the block-graph-change transactions:

bdrv_attach_child_common() stores BdrvChild** into transaction to clear
it on abort.

bdrv_attach_child_common() has two callers: bdrv_attach_child_noperm()
just pass-through this feature, bdrv_root_attach_child() doesn't need
the feature.

Look at bdrv_attach_child_noperm() callers:
  - bdrv_attach_child() doesn't need the feature
  - bdrv_set_file_or_backing_noperm() uses the feature to manage
    bs->file and bs->backing, we don't want it anymore
  - bdrv_append() uses the feature to manage bs->backing, again we
    don't want it anymore

So, we should drop this stuff! Great!

We could probably keep BdrvChild** argument to keep the int return
value, but it seems not worth the complexity.

Finally, we now set .file / .backing automatically in generic code and
want to restring setting them by hand outside of .attach/.detach.
So, this patch cleanups all remaining places where they were set.
To find such places I use:

  git grep '\->file ='
  git grep '\->backing ='
  git grep '&.*\<backing\>'
  git grep '&.*\<file\>'

1921b4f786 test-bdrv-graph-mod: fix filters to be filters
bdrv_pass_through is used as filter, even all node variables has
corresponding names. We want to append it, so it should be
backing-child-based filter like mirror_top.
So, in test_update_perm_tree, first child should be DATA, as we don't
want filters with two filtered children.

bdrv_exclusive_writer is used as a filter once. So it should be filter
anyway. We want to append it, so it should be backing-child-based
fitler too.

Make all FILTERED children to be PRIMARY as well. We are going to force
this rule by assertion soon.

Don't worry about setting bs->backing itself: in further commit we'll

code.

1dcea71979 test-bdrv-graph-mod: update test_parallel_perm_update test case
test_parallel_perm_update() does two things that we are going to
restrict in the near future:

1. It updates bs->file field by hand. bs->file will be managed
   automatically by generic code (together with bs->children list).

   Let's better refactor our "tricky" bds to have own state where one
   of children is linked as "selected".
   This also looks less "tricky", so avoid using this word.

2. It create FILTERED children that are not PRIMARY. Except for tests
   all FILTERED children in the Qemu block layer are always PRIMARY as
   well.  We are going to formalize this rule, so let's better use DATA
   children here.

3. It creates more than one FILTERED child, which is already abandoned
   in BDRV_CHILD_FILTERED's description.

While being here, update the picture to better correspond to the test
code.

69fbfff95e block: Refactor get_tmp_filename()
At present there are two callers of get_tmp_filename() and they are
inconsistent.

One does:

    /* TODO: extra byte is a hack to ensure MAX_PATH space on Windows. */
    char *tmp_filename = g_malloc0(PATH_MAX + 1);
    ...
    ret = get_tmp_filename(tmp_filename, PATH_MAX + 1);

while the other does:

    s->qcow_filename = g_malloc(PATH_MAX);
    ret = get_tmp_filename(s->qcow_filename, PATH_MAX);

As we can see different 'size' arguments are passed. There are also
platform specific implementations inside the function, and the use
of snprintf is really undesirable.

The function name is also misleading. It creates a temporary file,
not just a filename.

Refactor this routine by changing its name and signature to:

    char *create_tmp_file(Error **errp)

and use g_get_tmp_dir() / g_mkstemp() for a consistent implementation.

While we are here, add some comments to mention that /var/tmp is
preferred over /tmp on non-win32 hosts.

f1018ea0a3 tests: avoid DOS line endings in PSK file
Using FILE * APIs for writing the PSK file results in translation from
UNIX to DOS line endings on Windows. When the crypto PSK code later
loads the credentials the stray \r will result in failure to load the
PSK credentials into GNUTLS.

Rather than switching the FILE* APIs to open in binary format, just
switch to the more concise g_file_set_contents API.

fd66dbd424 blkio: add libblkio block driver
libblkio (https://gitlab.com/libblkio/libblkio/) is a library for
high-performance disk I/O. It currently supports io_uring,
virtio-blk-vhost-user, and virtio-blk-vhost-vdpa with additional drivers
under development.

One of the reasons for developing libblkio is that other applications
besides QEMU can use it. This will be particularly useful for
virtio-blk-vhost-user which applications may wish to use for connecting
to qemu-storage-daemon.

libblkio also gives us an opportunity to develop in Rust behind a C API
that is easy to consume from QEMU.

This commit adds io_uring, nvme-io_uring, virtio-blk-vhost-user, and
virtio-blk-vhost-vdpa BlockDrivers to QEMU using libblkio. It will be
easy to add other libblkio drivers since they will share the majority of
code.

For now I/O buffers are copied through bounce buffers if the libblkio
driver requires it. Later commits add an optimization for
pre-registering guest RAM to avoid bounce buffers.

The syntax is:

  --blockdev io_uring,node-name=drive0,filename=test.img,readonly=on|off,cache.direct=on|off

  --blockdev nvme-io_uring,node-name=drive0,filename=/dev/ng0n1,readonly=on|off,cache.direct=on

  --blockdev virtio-blk-vhost-vdpa,node-name=drive0,path=/dev/vdpa...,readonly=on|off,cache.direct=on

  --blockdev virtio-blk-vhost-user,node-name=drive0,path=vhost-user-blk.sock,readonly=on|off,cache.direct=on

e750a7ace4 9pfs: performance, Windows host prep, tests restructure
* Highlight of this PR is Linus Heckemann's GHashTable patch which
   brings massive general performance improvements of 9p server
   somewhere between factor 6 .. 12.
 
 * Bin Meng's g_mkdir patch is a preparatory patch for upcoming
   Windows host support of 9p server.
 
 * The rest of the patches in this PR are 9p test code restructuring
   and refactoring changes to improve readability and to ease
   maintenance of 9p test code on the long-term.

3ce77865bf tests/9p: remove unnecessary g_strdup() calls
This is a leftover from before the recent function merge and
refactoring patches:

As these functions do not return control to the caller in
between, it is not necessary to duplicate strings passed to them.

569f3b63ad tests/9p: merge *walk*() functions
Introduce declarative function calls.

There are currently 4 different functions for sending a 9p 'Twalk'
request: v9fs_twalk(), do_walk(), do_walk_rqids() and
do_walk_expect_error(). They are all doing the same thing, just in a
slightly different way and with slightly different function arguments.

Merge those 4 functions into a single function by using a struct for
function call arguments and use designated initializers when calling
this function to turn usage into a declarative approach, which is
better readable and easier to maintain.

Also move private functions genfid(), split() and split_free() from
virtio-9p-test.c to virtio-9p-client.c.

684f912034 tests/9p: split virtio-9p-test.c into tests and 9p client part
This patch is pure refactoring, it does not change behaviour.

virtio-9p-test.c grew to 1657 lines. Let's split this file up between
actual 9p test cases vs. 9p test client, to make it easier to
concentrate on the actual 9p tests.

Move the 9p test client code to a new unit virtio-9p-client.c, which
are basically all functions and types prefixed with v9fs_* already.

Note that some client wrapper functions (do_*) are preserved in
virtio-9p-test.c, simply because these wrapper functions are going to
be wiped with subsequent patches anyway.

As the global QGuestAllocator variable is moved to virtio-9p-client.c,
add a new function v9fs_set_allocator() to be used by virtio-9p-test.c
instead of fiddling with a global variable across units and libraries.

1c324bf908 tests/qtest: vhost-user-test: Fix [-Werror=format-overflow=] build warning
When tmpfs is NULL, a build warning is seen with GCC 9.3.0.
It's strange that GCC 11.2.0 on Ubuntu 22.04 does not catch this,
neither did the QEMU CI.

While we are here, improve the error message as well.

2872b0f390 target/i386: implement FMA instructions
The only issue with FMA instructions is that there are _a lot_ of them (30
opcodes, each of which comes in up to 4 versions depending on VEX.W and
VEX.L; a total of 96 possibilities).  However, they can be implement with
only 6 helpers, two for scalar operations and four for packed operations.
(Scalar versions do not do any merging; they only affect the bottom 32
or 64 bits of the output operand.  Therefore, there is no separate XMM
and YMM of the scalar helpers).

First, we can reduce the number of helpers to one third by passing four
operands (one output and three inputs); the reordering of which operands
go to the multiply and which go to the add is done in emit.c.

Second, the different instructions also dispatch to the same softfloat
function, so the flags for float32_muladd and float64_muladd are passed
in the helper as int arguments, with a little extra complication to
handle FMADDSUB and FMSUBADD.

cf5ec6641e target/i386: implement F16C instructions
F16C only consists of two instructions, which are a bit peculiar
nevertheless.

First, they access only the low half of an YMM or XMM register for the
packed-half operand; the exact size still depends on the VEX.L flag.
This is similar to the existing avx_movx flag, but not exactly because
avx_movx is hardcoded to affect operand 2.  To this end I added a "ph"
format name; it's possible to reuse this approach for the VPMOVSX and
VPMOVZX instructions, though that would also require adding two more
formats for the low-quarter and low-eighth of an operand.

Second, VCVTPS2PH is somewhat weird because it *stores* the result of
the instruction into memory rather than loading it.
