Hello Viresh
Hello,
This patchset adds toolstack support for I2C and GPIO virtio devices. This is
inspired from the work done by Oleksandr for the Disk device [1].
Great work!
The first two patches can be applied right away, but the last two need
Oleksandr's series [1] to be applied first.
I have reviewed patches #3/4 and #4/4 (libxl_arm.c changes).
FYI, I have recently pushed V8 of my series [1], which changes the code
in libxl_arm.c a bit.
This is developed as part of Linaro's Project Stratos, where we are working
towards Hypervisor agnostic Rust based backend [2].
I must accept that I am a beginner to Xen and developed this patchset based on
support for existing devices like Disk or Keyboard. There may be bits which I
missed or the one I added which aren't really required.
Thanks.
