KernelCrash_KdumpSoftlockup testcase use source files(softlockup.c and Makefile).These files added to op-tests framework's directory "op-test/test_binaries". This testcase activates the kernel panic on soft lockup and copy softlockup.c and Makefile to /tmp directory to build kernel module. The command insmod used to insert generated kernel module(softlockup.ko) into the kernel and verify the dump file created after kernel panic on soft lockup.

Add kdump-softlockup-testcase to PowerNVDump.py. This test needs kernel modules to create softlockup to crash the system due to panic on softlockup. Later , verify the dump file . If it exists , then test passed. otherwise , test failed.
How to run this testcase :
./op-test -c test.config --run testcases.PowerNVDump.KernelCrash_KdumpSoftlockupThis testcase use source files (softlockup.c and Makefile). These 2 files added to op-tests framework's directory
op-test/test_binaries. This testcase copy softlockup.c and Makefile to /tmp directory. Later, it will build kernel module for softlockup with the help of Makefile. To activate the kernel panic on soft lockup use this command$ sysctl -w kernel.softlockup_panic=1
The command
insmodused to insert generated kernel module ( i.e softlockup.ko) into the kernel.Finally , testcase will verify the dump file created after kernel panic on soft lockup.
