[Qemu-devel] [PATCH v3 2/4] qga: Fix mingw compilation warnings on enum conversion

[Cao Jiaxi]

The win2qemu[] is supposed to be the conversion table to convert between
STORAGE_BUS_TYPE in Windows SDK and GuestDiskBusType in qga.

But it was incorrectly written that it forces to set a GuestDiskBusType
value to STORAGE_BUS_TYPE, which generates an enum conversion warning in clang.

[Qemu-devel] [PATCH v3 4/4] osdep: Fix mingw compilation regarding stdio formats

[Cao Jiaxi]

I encountered the following compilation error on mingw:

/mnt/d/qemu/include/qemu/osdep.h:97:9: error: '__USE_MINGW_ANSI_STDIO' macro redefined [-Werror,-Wmacro-redefined]
 #define __USE_MINGW_ANSI_STDIO 1

It turns out that __USE_MINGW_ANSI_STDIO must be set before any

[Qemu-devel] [PATCH v3 0/4] Initial Windows on ARM (AArch64 64-Bit) host support

[Cao Jiaxi]

Initial Windows on ARM (AArch64 64-Bit) host support

This series of patches is for initial support of Windows 10 on ARM as a QEMU host.
Currently only TCG intepreter is working correctly, it crashes when TCG JIT is enabled.

For now we assume it is built using the clang aarch64-w64-mingw32 toolchain,
you can get a prebuilt toolchain at https://github.com/mstorsjo/llvm-mingw.

Cao Jiaxi (4):
  QEMU_PACKED: Remove gcc_struct attribute in Windows non x86 targets
  qga: Fix mingw compilation warnings on enum conversion
  util/cacheinfo: Use uint64_t on LLP64 model to satisfy Windows ARM64
  osdep: Fix mingw compilation regarding stdio formats

The slirp code is currently on its way into a separate module, so you
might need to provide that hunk to the libslirp folks again... I'm
putting the slirp maintainers on CC:, maybe they can pick it up from here.

Yes, the slirp module has now landed in master, so this patch
definitely needs to be split into two. I've kept in my
target-arm.next tree the parts which are applicable to
the QEMU repo itself (ie everything except the slirp/ change),
so we just need a new patch for the slirp submodule part.

Marc-André, Samuel -- what's the process for submitting and
getting reviewed changes to the slirp submodule now it's a
separate project ?

It's hosted on gitlab.freedesktop.org, with some CI. It's fine to send

gitlab is better than ML for patches & bug tracking tbh)
