Dear All,
I am trying to use perfctr driver along with centos 2.6.18-128.2.1.el5xen kernel. I tried following steps:
1. Installed the kernel source: src rpm (2.6.18-128.2.1.el5.src.rpm)
2. Patched the extracted kernel with perfcrt-2.6.38 available patch i.e. 2.6.18-128.el5-redhat.
3. Enabled the perfctr driver, global and virtual component
4. Atlast I tried to build, but the compile process gives an error while compiling kernel/sched.c. I tried to dig in to the code, but error says "perfcrt not found as a member in struct thread_struct", but the processor.h thread_struct has a member "perfctr".
As the patch was available for 2.6.18-128.el5, I also tried to patch 2.6.18-128.el5xen which is installed by default unless you perform a "yum update", but still the same issue.
Please suggest if someone is been successful in installing the perfctr driver.
Thanks in advance!
