e1319a2fbe Partial conversion of the linux trace checking to read in the file in the Memory Stage so it is possible to overwrite registers, memory, and interrupts. 2021-08-06 16:06:50 -05:00

d430659983 fixed the read timer issue but we still have problems with interrupts and i/o devices. 2021-08-06 10:16:06 -05:00

722d298c35 Fixed issue with desync of PCW and ExpectedPCW in linux test bench. The ERROR macro had a 10 ns delay which caused the trace to skip 1 instruction. 2021-08-05 16:49:03 -05:00

8823339aef added tests for 64/32 bit pma/pmp checker. They compile, but skip OVPsim simulation. They DO NOT pass regression yet 2021-07-23 16:02:42 -04:00

c39a228266 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
f234875779 dcache STATE_CPU_BUSY needs to assert CommittedM. This is required to ensure a completed memory operation is not bound to an interrupt. ie. MEPC should not be PCM when committed. 2021-07-14 23:08:07 -05:00
Ross Thompson
6163629204 Finally have the ptw correctly walking through the dcache to update the itlb. 
Still not working fully.
