Subject: [PATCH v2 0/4] powerpc/perf: IMC Cleanups
Date: Tue, 22 May 2018 14:42:33 +0530 [thread overview]
Message-ID: <1526980357-25385-1-git-send-email-anju@linux.vnet.ibm.com> (raw)
This patch series includes some cleanups and Unregistration of
thread-imc pmu, if the kernel does not have core-imc registered.
The entire patch set has been verified using the static checker smatch.
Command used:
$ make ARCH=powerpc CHECK="<path>/smatch -p=kernel" C=1 vmlinux | tee warns.txt
Tests Done:
* Fail core-imc at init:
nest-imc - working
cpuhotplug - works as expected
thread-imc - not registered
* Fail thread-imc at init:
nest-imc - works
core-imc - works
cpuhotplug - works
* Fail nest-imc at init
core-imc - works
thread-imc -works
cpuhotplug - works
* Fail only one nest unit (say for mcs23)
Other nest-units - works
core-imc - works
thread-imc - works
cpuhotplug - works.
* Kexec works
