Subject: [PATCH 0/4] kexec support for PARISC
Date: Sun, 8 Sep 2019 11:33:02 +0200 [thread overview]
Message-ID: <20190908093306.31455-1-svens@stackframe.org> (raw)
Hi,
this series adds support for the kexec syscalls to the PARISC architecture.
Note that kexec() on PA8800/PA8900 doesn't work yet as i haven't figured
out how to restart the CPUs on these systems.
For testing you can use my patched kexec-tools:
https://git.stackframe.org/cgit/kexec-tools/log/
I will submit these patches as soon as kexec is merged into the linux
kernel.
Thanks,
Sven
