From 7716e6548abed1582a7759666e79d5c612a906c7 Mon Sep 17 00:00:00 2001 From: Chandrakala Chavva Date: Thu, 17 Feb 2011 13:57:52 -0800 Subject: Octeon: Fix interrupt irq settings for performance counters. Octeon uses different interrupt irq for timer and performance counters. Set CvmCtl[IPPCI] to correct irq value very early.
