2008-02-27Add comments in code to describe bug conditions.Korey Sewell
This should help if somebody gets to the bug fix before me (or someone else)... --HG-- extra : convert_revision : 0ae64c58ef4f7b02996f31e9e9e6bfad344719e2
2008-02-27Fix Load/Store Queue squashing after a SMT thread is removed but ensuringKorey Sewell
you are squashing from the current instruction # causing the thread exit. --HG-- extra : convert_revision : ccbeece7dd1d5fee43f30ab19370908972113473
2008-02-27Fix offset in removeThread() function so that float registers start freeing upKorey Sewell
from the right point (#32 usually) instead of restarting at 0 and double-freeing. Commented out assert line in free_list.hh that will check for when double-free condition goes bad. --HG-- extra : convert_revision : 08d5f9b6a874736e487d101e85c22aaa67bf59ae

--HG-- extra : convert_revision : e04e438d7d261a61c52b946c23cd126ed648814a
2008-01-14The reason is that the event is supposed to put the instructions ready to ↵Ke Meng
execute for next cycle. And the FUCompletion event has a lower priority than CPU tick event. It is called after the iew->tick() for current cycle has already been executed and the issueToExecuteQueue has already advanced this time. And assume the issueToExecuteLatency is 1, to catch up, the increasement should be made at access(-1) instead of access(0). Otherwise I found it could increase the actual op_latency of the instructions to execute by 1 cycle and potentially put the simulated CPU into a permanent idle state.

2008-01-02Add ReadRespWithInvalidate to handle multi-level coherence situationSteve Reinhardt
where we defer a response to a read from a far-away cache A, then later defer a ReadExcl from a cache B on the same bus as us. We'll assert MemInhibit in both cases, but in the latter case MemInhibit will keep the invalidation from reaching cache A. This special response tells cache A that it gets the block to satisfy its read, but must immediately invalidate it. --HG-- extra : convert_revision : f85c8b47bb30232da37ac861b50a6539dc81161b
