From 3540ce8238c2d29a2a20a1876575c0064d0da23e Mon Sep 17 00:00:00 2001 From: John Williams Date: Tue, 24 Nov 2009 20:27:54 +1000 Subject: [PATCH] microblaze: Core oprofile configs and hooks Microblaze uses timer interrupt mode. Microblaze don't have any performance counter that's why we use just simple implementation.
