This patch introduces initial support for running RISC-V as a Xen guest.
It provides the necessary infrastructure and stubs for Xen-specific
operations. Key changes include:
- Modifications to the RISC-V kernel to integrate Xen-specific hypercalls
and interfaces, with function implementations stubbed for future work.
- Introduction of Xen-specific headers for RISC-V, including event
handling, hypervisor interaction, and page management. Functions are
defined but not yet implemented.
- Stub implementations for memory management, grant tables, and context
switching in the Xen environment, allowing further development and
integration.

Hi Milan, Slavisa,
Thank you very much for your contribution! Which Xen tree are you using
for development?
They are using [1] and have separate branches on top of latest. So we are in
sync. Also, if you are interested we have created a task/epics for this feature
in
[1] so you could also check there some details:
1.https://gitlab.com/groups/xen-project/people/olkur/-/epics/5
2.https://gitlab.com/xen-project/people/olkur/xen/-/issues/12
I am asking because RISC-V support in Xen is still in
the process of being upstreamed, and [1] is the tree that consolidates
all patches currently on the to-be-upstreamed list.
While the specific Xen tree you are using is not particularly important
at this stage, and using [1] is not a requirement, I am asking because
it is essential to align on the hypervisor ABI, especially regarding any
details that have not yet been upstreamed. Specifically, is there
anything in this patch series that relies on features not yet upstream
in Xen?
There are few features but some things which are Rt-Tk's branch in [1] could go
without waiting for these features to be upstreamed.
Thanks.
