From 30c516d51cad44f62a7269a59f067ae5a1be81df Mon Sep 17 00:00:00 2001 From: Kevin Lim Date: Thu, 6 Jul 2006 13:59:02 -0400 Subject: Support for draining, and the new method of switching out. Now switching out happens after the pipeline has been drained, deferring the three way handshake to the normal drain mechanism. The calls of switchOut() and takeOverFrom() both take action immediately. src/cpu/o3/commit.hh: src/cpu/o3/commit_impl.hh: src/cpu/o3/cpu.cc: src/cpu/o3/cpu.hh: src/cpu/o3/decode.hh: src/cpu/o3/decode_impl.hh: src/cpu/o3/fetch.hh: src/cpu/o3/fetch_impl.hh: src/cpu/o3/iew.hh: src/cpu/o3/iew_impl.hh: src/cpu/o3/rename.hh: src/cpu/o3/rename_impl.hh: Support for draining, new method of switching out. --HG-- extra : convert_revision : 05bf8b271ec85b3e2c675c3bed6c42aeba21f465 --- src/cpu/o3/decode.hh | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'src/cpu/o3/decode.hh') diff --git a/src/cpu/o3/decode.hh b/src/cpu/o3/decode.hh index 1edf3335d..1e96f1884 100644 --- a/src/cpu/o3/decode.hh +++ b/src/cpu/o3/decode.hh @@ -109,8 +109,14 @@ class DefaultDecode /** Sets pointer to list of active threads. */ void setActiveThreads(std::list *at_ptr); + /** Drains the decode stage. */ + void drain(); + + /** Resumes execution after a drain. */ + void resume() { } + /** Switches out the decode stage. */ - void switchOut(); + void switchOut() { } /** Takes over from another CPU's thread. */ void takeOverFrom(); -- cgit v1.2.3
