From 6daada2701c7ea361843a7c2a50cb616b56b1519 Mon Sep 17 00:00:00 2001 From: Andreas Sandberg Date: Mon, 7 Jan 2013 13:05:44 -0500 Subject: cpu: Initialize the O3 pipeline from startup() The entire O3 pipeline used to be initialized from init(), which is called before initState() or unserialize(). This causes the pipeline to be initialized from an incorrect thread context. This doesn't currently lead to correctness problems as instructions fetched from the incorrect start PC will be squashed a few cycles after initialization. This patch will affect the regressions since the O3 CPU now issues its first instruction fetch to the correct PC instead of 0x0. --- src/cpu/o3/fetch.hh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/cpu/o3/fetch.hh') diff --git a/src/cpu/o3/fetch.hh b/src/cpu/o3/fetch.hh index 42ea5cb71..702a45e15 100644 --- a/src/cpu/o3/fetch.hh +++ b/src/cpu/o3/fetch.hh @@ -215,7 +215,7 @@ class DefaultFetch void setFetchQueue(TimeBuffer *fq_ptr); /** Initialize stage. */ - void initStage(); + void startupStage(); /** Tells the fetch stage that the Icache is set. */ void setIcache(); -- cgit v1.2.3
