Hi all,
here are some tests to test the cpu hotplug.
Any feedback would be appreciate
Thanks a lot
-- Daniel
Test 1: check the sysfs files are present
=========================================
for each cpu
* check /sys/devices/system/cpu/cpuX/online is there
What about the particular case for cpu0 where the 'online' file is there
but shouldn't as the other arch ?
Test 2: check cpu state is reflected in sysfs
=============================================
for each cpu
* set cpuX offline
* check cpuX status is offline
* set cpuX back online
* check cpuX status is online
Test 3: check the affinity does not work on an online cpu
=========================================================
for each cpu
* set cpuX offline
* check 'taskset -c X /bin/true' fails
* set cpuX back online
Test 4: check cpus are reflected on /proc/cpuinfo correctly
===========================================================
NRCPUS=<number of configured cpu on the system>
for each cpu
* set cpuX offline
* check /proc/cpuinfo 'processor' keyword count is 'NRCPUS - 1'
* check the processor keyword contains a cpu id different from the cpu
we offlined
* set cpuX back online
Test 5: test userspace notification
===================================
for each cpu
* set cpuX offline
* check from userspace notification has been done with the command
'udevadm monitor --kernel --subsystem-match=cpu'
* and the event is related to the cpuX and 'offline'
* set the cpu online
* check from userspace notification has been done with the command
'udevadm monitor --kernel --subsystem-match=cpu'
* and the event is related to the cpuX and 'online'
Test 6: do some stress test
===========================
for each cpu
* for i in 1 .. 50
* set cpuX offline
* set cpuX back online
