Hi Shwetabh,
> 3. Went to /opt/ltp directory and tried to execute cpuhotplug test:
> [r...@localhost ~]# cd /opt/ltp/
> [r...@localhost ltp]# ./runltp -f cpuhotplug
>
Please find attached the quick 'n' dirty patch
(cpu_hotplugin_makefile.patch) to execute cpuhotplugin test.
I have observed that the 'hotplug' directory is not included in
"testcases/kernel/Makefile". I have also
created a Makefile in 'hotplug/cpu_hotplug' directory.
After applying this patch, I have followed the usual ./configure;
make; sudo make install steps and executed
the cpuhotplug test and observed the below given output . It seems
like the test execution is "not so good" in
my machine. Your mileage may vary.
Garret,Rishi, please review the patch and let me know your comments.
