From 801ce65eaeda04017ac0df544eaa4c8ffae98455 Mon Sep 17 00:00:00 2001 From: Andreas Hansson Date: Fri, 27 Mar 2015 04:55:59 -0400 Subject: [PATCH] mem: Remove redundant allocateUncachedReadBuffer in cache This patch removes the no-longer-needed allocateUncachedReadBuffer. Besides the checks it is exactly the same as allocateMissBuffer and thus provides no value. --- src/mem/cache/base.hh | 14 +------------- src/mem/cache/cache_impl.hh | 2 +- 2 files changed, 2 insertions(+), 14 deletions(-) diff --git a/src/mem/cache/base.hh b/src/mem/cache/base.hh index 16160dba3..2bac2d30f 100644 --- a/src/mem/cache/base.hh +++ b/src/mem/cache/base.hh @@ -210,9 +210,7 @@ class BaseCache : public MemObject * * allocateBufferInternal() function is called in: * - MSHR allocateWriteBuffer (unchached write forwarded to WriteBuffer); - * - MSHR allocateMissBuffer (cacheable miss in MSHR queue); - * - MSHR allocateUncachedReadBuffer (unchached read allocated in MSHR - * queue) + * - MSHR allocateMissBuffer (miss in MSHR queue); */ MSHR *allocateBufferInternal(MSHRQueue *mq, Addr addr, int size, PacketPtr pkt, Tick time, bool requestBus) @@ -501,7 +499,6 @@ class BaseCache : public MemObject MSHR *allocateMissBuffer(PacketPtr pkt, Tick time, bool requestBus) { - assert(!pkt->req->isUncacheable()); return allocateBufferInternal(&mshrQueue, blockAlign(pkt->getAddr()), blkSize, pkt, time, requestBus); @@ -515,15 +512,6 @@ class BaseCache : public MemObject pkt, time, requestBus); } - MSHR *allocateUncachedReadBuffer(PacketPtr pkt, Tick time, bool requestBus) - { - assert(pkt->req->isUncacheable()); - assert(pkt->isRead()); - return allocateBufferInternal(&mshrQueue, - blockAlign(pkt->getAddr()), blkSize, - pkt, time, requestBus); - } - /** * Returns true if the cache is blocked for accesses. */ diff --git a/src/mem/cache/cache_impl.hh b/src/mem/cache/cache_impl.hh index 93ef34bb2..daff61d8e 100644 --- a/src/mem/cache/cache_impl.hh +++ b/src/mem/cache/cache_impl.hh @@ -555,7 +555,7 @@ Cache::recvTimingReq(PacketPtr pkt) pkt->headerDelay; // Reset the timing of the packet. pkt->headerDelay = pkt->payloadDelay = 0; - allocateUncachedReadBuffer(pkt, allocate_rd_buffer_time, true); + allocateMissBuffer(pkt, allocate_rd_buffer_time, true); } assert(pkt->needsResponse()); // else we should delete it here?? return true; -- 2.30.2
