Hi Venkatesh,
I have applied the following patches for the incorrect
accounting of irq into the running task .
[PATCH] x86: Add IRQ_TIME_ACCOUNTING
[e82b8e4ea4f3dffe6e7939f90e78da675fcc450e]
[PATCH] sched: Add IRQ_TIME_ACCOUNTING, finer accounting of irq time
[b52bfee445d315549d41eacf2fa7c156e7d153d5]
[PATCH] sched: Do not account irq time to current task
[305e6835e05513406fa12820e40e4a8ecb63743c]
[PATCH] sched: Export ns irqtimes through /proc/stat
[abb74cefa9c682fb38ba86c17ca3c86fed6cc464]
But still the stime and utime of the process in
/proc/pid/stat is high . I think the above patches does
not update
The stime and utime values in /proc/pid/stat .
Or am I missing anything ?
Regards,
Shaiju.

Just checking that you do have CONFIG_IRQ_TIME_ACCOUNTING=y in your
kernel config?
