      lq: Remove LQ data (#1862) · 683c1411
      happy-lx 提交于
      This PR remove data in lq.
      
      All cache miss load instructions will be replayed by lq, and the forward path to the D channel
      and mshr is added to the pipeline.
      Special treatment is made for uncache load. The data is no longer stored in the datamodule
      but stored in a separate register. ldout is only used as uncache writeback, and only ldout0
      will be used. Adjust the priority so that the replayed instruction has the highest priority in S0.
      
      Future work:
      1. fix `milc` perf loss
      2. remove data from MSHRs
      
      * difftest: monitor cache miss latency
      
      * lq, ldu, dcache: remove lq's data
      
      * lq's data is no longer used
      * replay cache miss load from lq (use counter to delay)
      * if dcache's mshr gets refill data, wake up lq's missed load
      * uncache load will writeback to ldu using ldout_0
      * ldout_1 is no longer used
      
      * lq, ldu: add forward port
      
      * forward D and mshr in load S1, get result in S2
      * remove useless code logic in loadQueueData
      
      * misc: revert monitor
