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