271fec6f18 vfio/listener: Add an assertion for unmap_all
Currently the maximum of iommu address space is 64bit. So when a maximum
iommu memory section is deleted, it's in scope [0, 2^64). Add a
assertion for that.

b30823e561 vfio/iommufd: Support unmap all in one ioctl()
IOMMUFD kernel uAPI supports unmapping whole address space in one call with
[iova, size] set to [0, UINT64_MAX], this can simplify iommufd_cdev_unmap()
a bit. See iommufd_ioas_unmap() in kernel for details.

962bcf0911 vfio/container: Support unmap all in one ioctl()
VFIO type1 kernel uAPI supports unmapping whole address space in one call
since commit c19650995374 ("vfio/type1: implement unmap all"). Use the
unmap_all variant whenever it's supported in kernel.

Opportunistically pass VFIOLegacyContainer pointer in low level function
vfio_legacy_dma_unmap_one().

725ec89803 accel/kvm: Fix an erroneous check on coalesced_mmio_ring
According to KVM uAPI, coalesced mmio page is KVM_COALESCED_MMIO_PAGE_OFFSET
offset from kvm_run pages. For x86 it's 2 pages offset, for arm it's 1 page
offset currently. We shouldn't presume it's hardcoded 1 page or else
coalesced_mmio_ring will not be cleared in do_kvm_destroy_vcpu() in x86.

8bf49fff0d vfio/iommufd: Restore vbasedev's reference to hwpt after CPR transfer
After CPR transfer, if there are more than one VFIO devices, device is
not added to hwpt->device_list and its reference to hwpt isn't restored
on destination. We still need to call iommufd_cdev_attach_container() to
restore it after a matching container is found, or else SIGSEV triggers.

8a2b283efa gitlab-ci: Decrease the size of the compiler cache
Uploading the cache from the runner takes a long time in the MSYS2
job, mostly due to the size of the compiler cache.
However, looking at runs with a non-poluted cache, it seems like
you can get a build with a 99% hit rate already with ~ 160 MiB cache
size, so the compiler cache with 500 MiB certainly contains a lot of
stale files. Thus decrease the size of the ccache to a more reasonable
value to speed up the MSYS2 job in our CI.

While at it, also add a "du -sh" for the build folder to get a better
feeling for the amount of object code that is required for the build,
and publish the list of files in /var/cache to be able to better
analyze what is really clogging our cache here.

049271a2ea hw/core/machine: Remove MachineClass::fixup_ram_size callback
The MachineClass::fixup_ram_size callback, which was added
in commit 5c30ef937f ("vl/s390x: fixup ram sizes for compat
machines"), was only used by the s390-ccw-virtio-4.2 machine,
which got removed. Remove it as now unused.

8a545a336d contrib/plugins/uftrace_symbols.py: generate debug files to map symbols to source
Enhance uftrace_symbols.py to generate .dbg files, containing
source location for every symbol present in .sym file.
It allows to use `uftrace {replay,dump} --srcline` and show origin of
functions, connecting trace to original source code.

It was first implemented with pyelftools DWARF parser, which was way
too slow (~minutes) to get locations for every symbol in the linux
kernel. Thus, we use `addr2line` instead, which runs in seconds.

As well, there were some bugs with latest pyelftools release,
requiring to run master version, which is not installable with pip.
Thus, since we now require binutils (addr2line), we can ditch pyelftools
based implementation and simply rely on `nm` to get symbols information,
which is faster and better.

77dc9d662f tests/tcg/multiarch/linux/linux-test: Don't try to test atime update
The linux-test test includes an attempt to check the utime and stat
syscalls by setting the atime and mtime of a file to specific values,
and then calling stat() to check that the values read back correctly.

Unfortunately this is flaky, as it will fail if some other process
(for instance a virus scanner, backup program, etc) gets in and reads
the file between the utime() and stat() call, resulting in a host
syscall sequence like this:

utimensat(AT_FDCWD, "file2",
  [{tv_sec=1001, tv_nsec=0} /* 1970-01-01T01:16:41+0100 */,
   {tv_sec=1000, tv_nsec=0} /* 1970-01-01T01:16:40+0100 */], 0) = 0
# successfully set atime to 1001 and mtime to 1000
statx(AT_FDCWD, "file2", AT_STATX_SYNC_AS_STAT|AT_NO_AUTOMOUNT,
  STATX_BASIC_STATS,
  {stx_mask=STATX_BASIC_STATS|STATX_MNT_ID,
   stx_blksize=4096, stx_attributes=0, stx_nlink=1, stx_uid=32808,
   stx_gid=32808, stx_mode=S_IFREG|0600, stx_ino=21659016,
   stx_size=100, stx_blocks=8,
   stx_attributes_mask=STATX_ATTR_COMPRESSED|STATX_ATTR_IMMUTABLE|
         STATX_ATTR_APPEND|STATX_ATTR_NODUMP|STATX_ATTR_ENCRYPTED|
         STATX_ATTR_AUTOMOUNT|STATX_ATTR_MOUNT_ROOT|STATX_ATTR_VERITY|
         STATX_ATTR_DAX,
   stx_atime={tv_sec=1760091862, tv_nsec=63509009} /* 2025-10-10T11:24:22.063509009+0100 */,
   stx_ctime={tv_sec=1760091862, tv_nsec=63509009} /* 2025-10-10T11:24:22.063509009+0100 */,
   stx_mtime={tv_sec=1000, tv_nsec=0} /* 1970-01-01T01:16:40+0100 */,
   stx_rdev_major=0, stx_rdev_minor=0, stx_dev_major=252,
   stx_dev_minor=0, stx_mnt_id=0x1f}) = 0
# but when we statx the file, we get back an mtime of 1000
# but an atime corresponding to when the other process read it

and which will cause the test program to fail with the error
message "stat time".

In theory we could defend against this by e.g.  operating on files in
a dummy loopback mount filesystem which we mounted as 'noatime', but
this isn't worth the hassle.  Just drop the check on atime.

76a7a71587 gitlab: drop aarch32 runner and associated bits
While working out what hoops to jump through to get a full set of
aarch32 packages installed on the aarch64 runner it was pointed out 32
bit host support is deprecated. As the extra packages where needed for
system emulation (marked deprecated since 8.0!) there didn't seem much
point keeping this in.

While the full expunging of 32 bit host support will probably be done
for 11.0 we can at least reduce the CI burden a bit now.

We keep all the current allow_fail and configure setups but do take
the opportunity to replace the -j`nproc --ignore=40` hack with
something that almost, but not quite, saturates the machine its being
built on.

3a2d5612a7 .gitlab-ci.d/buildtest.yml: Install 'file' for the Coverity job
The coverity-scan upload job has started failing as of 30th
September:

[ERROR] Cannot find '/usr/bin/file' command, and no 'file' command is found in the PATH
        Coverity Capture uses this tool to identify the file type of executables.
        Please ensure '/usr/bin/file' is available, or add the 'file' utility to your PATH.

This seems to have broken when we moved our containers from Fedora 40
to 41 -- probably F40 indirectly pulled in 'file' via some other
dependency, but in F41 it does not.

Explicitly install 'file' for the coverity job, in the same way we
already do for curl and wget.

e01046a140 target/hexagon: Replace prepare script with meson target
The purpose of the prepare script is to invoke `cpp` to preprocess input
to idef-parser by expanding a few select macros.  On macOS `cpp`
expands into `clang ... -traditional-cpp` which breaks macro
concatenation.  Replace `cpp` with `${compiler} -E`
and replace the script with a meson custom_target.

To remove any confusion with HVX or other potential store instructions,
we'll qualify this context var with "scalar".

4a11070978 linux-user/hexagon: Fix sigcontext
In order to correspond with the kernel, we've now (1) moved the
preds[] to the right offset and combined the representation as a single
ulong "p3_0", (2), added the cs{0,1} registers, (3) added a pad for 48
words, (4) added the user regs structure to an 8-byte aligned
target_sigcontext structure.
