[Qemu-devel] [PATCH v2 0/3] Linux usermode emulation user mode USB driver support.

[Cortland Tölva]

This patch series aims to let programs running under QEMU Linux user mode
emulation implement user-space USB drivers via the USBFS ioctl()s.  First
I check for the necessary header files, then I define some types, and
last I implement the submit, discard, and reap functions, which involve
USB request buffers which live beyond a single ioctl() call.

Each patch in this series compiles for i386, ppc64, ppc64le, mips, mipsel,
xtensa, and xtensaeb with an armv7l host and an x86_64 host.  The
i386-linux-user target is tested working with a USB scanner driver on an
armv7l host.  Additionally, a patched copy of strace was used to verify
the conversion for reaping.  Additionally, a MIPS binary of lsusb was run
on armv7l host to check reaping and other functionality across endianness.

Not tested on 64-bit hosts.

Changes from v1:
  use check_include in configure
  move struct definitions to later patch where possible
  improve pointer cast to int compatibility
  remove unimplemented types for usb streams

Cortland Tölva (3):
  linux-user: Check for Linux USBFS in configure
  linux-user: Define ordinary usbfs ioctls.
  linux-user: implement special usbfs ioctls.
