| |
Hi Andi/Andrew
Here are a set of patches to implement physical cpu hotplug for x86_64 arch.
Physical cpu hotplug support is already available for ia64, these set of patches extend support for x86_64 as well.
Patches are split as follows. Please help the first 3 patches stage in -mm before considering for mainline inclusion. The last 2 patches are purely for testing.
1. remove-processor-entries-on-eject - Minor bugfix to current base code. 2. remove-unused-lapic-entry - Remove unnecessary lapic definition 3. x86_64-physical-cpu-hotplug.patch - Physical cpu hotplug support for x86_64
The following two patches are not for mainline inclusion. They exist so we could test the code paths to test physical hotplug without need for a platform that is capable of hotplug.
Procedure to do this is included in sci emulate patches. 4. x86_64-limit-cpus - Limit cpus present to emulate Physical hotplug. 5. sci_emu.patch - Code to emulate SCI notify on a object.
Cheers, ashok
