Subject: [kvm-unit-tests PATCH v5 0/3] s390x: css: pv: css test adaptation for PV
Date: Fri, 22 Jan 2021 14:27:37 +0100 [thread overview]
Message-ID: <1611322060-1972-1-git-send-email-pmorel@linux.ibm.com> (raw)
Hi all,
To adapt the CSS I/O tests to protected virtualisation we need
utilities to:
1- allocate the I/O buffers in a private page using (patch 2)
It must be in a dedicated page to avoid exporting code or
guest private data to the host.
We accept a size in byte and flags and allocate page integral
memory to handle the Protected Virtualization.
2- share the I/O buffers with the host (patch 1)
This patch uses the page allocator reworked by Claudio.
The 2 first patches are the implementation of the tools,
patch 3 is the modification of the css.c test for PV.
The checkpatch always asked me to modify MAINTAINERS,
so I added me as reviewer to be in copy for CSS at least.
May be we could create a finer grain MAINTAINERS in the
future.
regards,
Pierre
