e0f719d513 Updated the ptw, lsuarb and dcache to hopefully solve the interlock issues. 2021-07-16 11:12:57 -05:00

abd5b1c02d Still broken, midway through fixing understanding of how ptw and datacache interact in time especially wrt adrE, adrM, faults, and tlb interaction. 2021-07-15 18:30:29 -04:00

e5d624c1fa Found bug in the PMA such that invalid addresses were sent to the tim. Once addressing this issue the sv48 test fails early with a pma access fault. 2021-07-15 11:56:35 -05:00

fa26aec588 Merge branch 'main' into dcache 2021-07-15 11:55:20 -05:00

b9902b0560 Fixed how the dcache and page table walker stall cpu so that once a tlb miss occurs the CPU is always stalled until the walk is complete, the tlb updated, and the dcache fetched and hits. 2021-07-15 11:00:42 -05:00
Ross Thompson
ba1e1ec231 Finally have the ptw correctly walking through the dcache to update the itlb. 
Still not working fully.
