From a69ba6293d11b7dfd395a742f3449d6ddda8ecad Mon Sep 17 00:00:00 2001 From: Jayachandran C Date: Mon, 14 Jan 2013 15:11:56 +0000 Subject: MIPS: Netlogic: Split XLP L1 i-cache among threads Since we now use r4k cache code for Netlogic XLP, it is better to split L1 icache among the active threads, so that threads won't step on each other while flushing icache. The L1 dcache is already split among the threads in the core.
