oprofile problem in centos with custom kernel
...s shouting, I know that custom kernels are not
supported by centos team, however I really
need to run a modified version, due to a project concerning my MSc
thesis. So i hope for your understanding :-) .
I have build the kernel with the following flags:
CONFIG_DEBUG_KERNEL=y
CONFIG_OPROFILE=y
# CONFIG_OPROFILE_EVENT_MULTIPLEX is not set
CONFIG_HAVE_OPROFILE=y
CONFIG_FRAME_POINTER=y
CONFIG_KPROBES=y
CONFIG_HAVE_KPROBES=y
CONFIG_KPROBE_EVENT=y
CONFIG_SAMPLE_KPROBES=m
under various suggestions i have googled in the net. I run oprofile
using the following instructions:
#!/bin/bash
rm oprof_output.txt
/usr/bin/opcontrol -...

[PATCH] x86/paravirt: Avoid setting IF flag, if not necessary
Setting the IF flag can cause an VM exit. So we should avoid touching
the IF flag until absolutely necessary. This patch change the way
the paravirt arch_local_irq_restore() works by checking the previous
flags value and call arch_local_irq_enable() only if the IF flag was
set previously.
On a 32 vCPUs KVM guest running the AIM7 five-sec workload,
the performance increased slightly from 302136.32
