Subject: [PATCH 0/6] pseries: Move CPU dlpar into the kernel
Date: Mon, 22 Jun 2015 15:54:23 -0500 [thread overview]
Message-ID: <558875FF.2040000@linux.vnet.ibm.com> (raw)
To better support CPU hotplug in PowerKVM and PowerVM environments, the
handling of CPU dlpar should be done entirely in the kernel. This will allow
a common entry point for PowerVM and PowerKVM CPU dlpar requests. For both
environments, the entry point is the same one introduced in a previous
patch set that moved memory hotplug into the kernel. The entry point accepts
a rtas hotplug event which is either constructed when using the
/sys/kernel/dlpar interface or is passed to the kernel when handling a
ras epow interrupt.
-Nathan
Patch 1/6:
- Consolidate cpu hotplug code from pseries/dlpar.c to pseries/hotplug-cpu.c
Patch 2/6:
- Factor out common code pieces for both environments
Patch 3/6:
- Update cpu dlpar error recovery
Patch 4/6:
- Add cpu hotplug remove capability
Patch 5/6:
- Add cpu hotplug add capability
Patch 6/6:
- Enable sysfs interface for cpu hotplug
