Subject: [kvm-unit-tests PATCH v3 0/3] s390x: css: pv: css test adaptation for PV
Date: Tue, 19 Jan 2021 20:52:21 +0100	[thread overview]
Message-ID: <1611085944-21609-1-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.

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.

regards,
Pierre
