2007-03-23Updates for commit.Kevin Lim
1. Move interrupt handling to a separate function to clean up main commit() function a bit. Also gate the function call off properly based on whether or not there are outstanding interrupts, and the system is not in PAL mode. 2. Better handling of updating instruction's status bits. Instructions are not marked "atCommit" until other stages view it (pushed off to IEW/IQ), and they have been properly handled (faults). 3. Don't consider the ROB "empty" for the purpose of other stages until the ROB is empty, all stores have written back, and there was no store commits this cycle. The last is necessary in case a store committed, in which case it would look like all stores have written back but in actuality have not. src/cpu/o3/commit.hh: Slightly modify how interrupts are handled. Also include some extra bools to keep track of state properly. src/cpu/o3/commit_impl.hh: Slightly modify how interrupts are handled. Also include some extra bools to keep track of state. General correctness updates, most specifically for when commit broadcasts to other stages that the ROB is empty. --HG-- extra : convert_revision : 682ec6ccf4ee6ed0c8a030ceaba1c90a3619d102
2007-03-23Handle status bits a little better, as well as non-speculative instructions.Kevin Lim
src/cpu/o3/iew_impl.hh: Allow for slightly more flexible handling of non-speculative instructions. They can be other classes now, such as loads or stores. Also be sure to clear the state associated with squashes that are not used. i.e. if a squash due to a memory ordering violation happens on the same cycle as an older branch squashing, clear the state associated with the memory ordering violation. Lastly don't consider uncached loads to officially be "at commit" until IEW receives the signal back from commit about the load. src/cpu/o3/inst_queue_impl.hh: Don't consider non-speculative instructions to be "at commit" until the IQ has received a signal from commit about the instruction. This prevents non-speculative instructions from being issued too early. src/cpu/o3/mem_dep_unit_impl.hh: Clear instruction's ability to issue if it's replayed. --HG-- extra : convert_revision : d69dae878a30821222885485f4dee87170d56eb3
2007-03-23Two fixes:Kevin Lim
1. Requests are handled more properly now. They assume the memory system takes control of the request upon sending out an access. 2. load-load ordering is maintained. src/cpu/base_dyn_inst.hh: Update how requests are handled. The BaseDynInst should not be able to hold a pointer to the request because the request becomes owned by the memory system once it is sent out. Also include some functions to allow certain status bits to be cleared. src/cpu/base_dyn_inst_impl.hh: Update how requests are handled. The BaseDynInst should not be able to hold a pointer to the request because the request becomes owned by the memory system once it is sent out. src/cpu/o3/fetch_impl.hh: General correctness fixes. retryPkt is not necessarily always set, so handle it properly. Also consider the cache unblocked only when recvRetry is called. src/cpu/o3/lsq_unit.hh: Handle requests a little more correctly. Now that the requests aren't pointed to by the DynInst, be sure to delete the request if it's not being used by the memory system. Also be sure to not store-load forward from an uncacheable store. src/cpu/o3/lsq_unit_impl.hh: Check to make sure load-load ordering was maintained. Also handle requests a little more correctly. --HG-- extra : convert_revision : e86bead2886d02443cf77bf7a7a1492845e1690f
2007-03-23A couple of minor fixes.Kevin Lim
1. Set CPU ID in all modes for the O3 CPU. 2. Use nextCycle() function to prevent phase drift in O3 CPU. 3. Remove assertion in rename map that is no longer true. src/cpu/o3/alpha/cpu_builder.cc: Allow for CPU id in all modes, not just full system. Also include a parameter that was left out by accident. src/cpu/o3/alpha/cpu_impl.hh: Set the CPU ID properly. src/cpu/o3/cpu.cc: src/cpu/o3/cpu.hh: Use nextCycle() function so that the CPU does not get out of phase when starting up from quiesces. src/cpu/o3/rename_map.cc: Remove assertion that is no longer true. tests/configs/o3-timing.py: Set CPU's id to 0. --HG-- extra : convert_revision : 2b69c19adfce2adcc2d1939e89d702bd6674d5d5
