Subject: [PATCH V3 0/3] gpio: Add virtio based driver
Date: Thu, 10 Jun 2021 17:39:05 +0530 [thread overview]
Message-ID: <cover.1623326176.git.viresh.kumar@linaro.org> (raw)
Hello,
This adds a virtio based GPIO driver based on the proposed specification [1].
The first two versions [2] were sent by Enrico earlier and here is a newer version.
I have retained the authorship of the work done by Enrico (1st patch) to make
sure we don't loose his credits.
I have tested all basic operations of the patchset (with Qemu guest) with the
libgpiod utility. I have also tested the handling of interrupts on the guest
side. All works as expected.
I will now be working towards a Rust based hypervisor agnostic backend to
provide a generic solution for that.
This should be merged only after the specifications are merged, I will keep
everyone posted for the same.
I am not adding a version history here as a lot of changes have been made, from
protocol to code and this really needs a full review from scratch.
