Subject: [PATCH V2 0/2] xen: privcmd: Add ioeventfd support
Date: Thu, 5 Oct 2023 15:55:10 +0530 [thread overview]
Message-ID: <cover.1696500578.git.viresh.kumar@linaro.org> (raw)
Hello,
Now that irqfd support (backend to guest interrupt) is already merged, this
series solves the other part of the problem, i.e. ioeventfd (guest to backend
interrupt).
More details inside the commits.

V1->V2:
- Increment irq_info refcnt only for valid info.
- Use u64 type for addr.
- Add comments for use of barriers.
- Use spin lock instead of mutex as we need to use them in irq handler.
- Add a warning when kioreq is getting freed and ioeventfds list isn't empty.
- Use struct_size().
- Validate number of vcpus as well.
