[LTP] Hotplug CPU testsuite

[Bryce H. <br...@os...>]

Hi Marty,

Gerrit suggested this testsuite might be worth including in LTP.

    http://developer.osdl.org/dev/hotplug/tests/

This is a set of test cases the OSDL-DCL Hotplug SIG developed to validate
the CPU hotplug functionality in the kernel.  It onlines/offlines CPUs,
checks that top behaves correctly when cpu's appear and disappear, etc.
A summary of the test cases is here:

http://www.developer.osdl.org/maryedie/HOTPLUG/planning/hotplug_cpu_test_plan_status.html

Additional documentation is included in the tarball.

Note that the first test case caused a crash on x86, so take care if you
run this on x86 systems.  It's been tested to work properly on PPC64,
and in theory should run properly on all architectures.  I would be very
interested in hearing about failures on other architectures.
