[PATCH V3 0/6] Virtio toolstack support for I2C and GPIO on Arm
Posted by Viresh Kumar 1 year, 7 months ago
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.

This is developed as part of Linaro's Project Stratos, where we are working
towards Hypervisor agnostic Rust based backend [1].

This is based of origin/staging (commit 01ca29f0b17a ("sched: dom0_vcpus_pin
should only affect dom0")) which already has Oleksandr's patches applied.

V2->V3:
- Rebased over latest tree and made changes according to changes in Oleksandr's
  patches from sometime back.
- Minor cleanups.

V1->V2:
- Patches 3/6 and 4/6 are new.
- Patches 5/6 and 6/6 updated based on the above two patches.
- Added link to the bindings for I2C and GPIO.
- Rebased over latest master branch.


Thanks.

Thanks, I have reviewed all patches that touch libxl_arm.c (##3-6)
