Subject: [PATCH 0/3] Use NMI to stop cpus
Date: Tue, 11 Oct 2011 11:24:43 -0400 [thread overview]
Message-ID: <1318346686-12349-1-git-send-email-dzickus@redhat.com> (raw)
This patch series attempts to use NMI to stop cpus instead of the
REBOOT_VECTOR irq. The idea is to have a more robust and reliable
way to stop cpus when serializing things like the panic path.
More details in the changelogs.
Don Zickus (3):
x86, reboot: Use NMI instead of REBOOT_VECTOR to stop cpus
x86, NMI: Add NMI IPI selftest
x86, NMI: knob to disable using NMI IPIs to stop cpus
