Subject: [PATCH 0/8] Add support for pvpanic mmio device
Date: Thu, 22 Oct 2020 10:42:48 +0300 [thread overview]
Message-ID: <1603352576-21671-1-git-send-email-mihai.carabas@oracle.com> (raw)
The patchset was assembled from chuncks from some old patches from 2018 [1]
which were left unmerged and some additions from me. Surprisingly their Linux
kernel counterpart were merged (so the pvpanic driver from the kernel supports
mmio).
I have seen the discussions about moving the pvpanic to PCI [1]. Those patches
were sent but nothing happened. Also they are not trivial and require major
modifications at the driver level also. Given the fact that we already have
mmio driver support for pvpanic in the Linux kernel, I have sent these patches
to ask again the maintainers if this can be merged.
How to test this:
/usr/bin/qemu-system-aarch64 \
-machine virt,gic-version=3,pvpanic=on
There is a new property for machine virt called pvpanic which is by default
turned off.
