David Harris	ed9a834bc1	Merge pull request #304 from ross144/main ... Fixes bug 203 and linux/ImperasDV mismatch at 571M instructions	2023-05-30 13:37:00 -07:00
Ross Thompson	3c94c186db	Possible fix for Linux bug and bug 203. ImperasDV mismatches in linux boot around 571M instructions after the login prompt. ... This bug occurs when there are back to back HPTW requests and the first generates an access fault during the walk. The old implementation uses a delayed version of the fault to prevent the HTPW fsm from transitioning out of the IDLE state. Because the first request generates the fault and the second request is pipelined the second request appears as if it also faults so the FSM does not perform the walk. The new implementation adds a FAULT state. When the HPTW generates an access fault it transitions to this state removes the HPTWStall and then transitions to IDLE. There may still be a remaining bug here if the pipeline is stalled for another reason. However I don't think it is possible by construction. The only possible sources of stalls at this point would be IFU and LSU stalls and both are required to make this condition happen.	2023-05-30 15:20:24 -05:00

Ross Thompson	340aac0934	Got the branch predictor parameterized using Lim's method. Also had to add a global enum included in both cvw.sv and the configs which defines the branch predictor types. This should be synthesizable, but I'll need to double check.	2023-05-26 16:00:14 -05:00
