1cad05fef9 Minor cleanup of cache. 2022-07-19 23:04:23 -05:00
Ross Thompson
8698799077 Reverted to fetched the demand cache line first then doing the eviction. This is important because of an optimization in the replacement policy. The replacement policy updates the LRU 1 cycle late and reads the LRU 1 cycle late for critical path timing. This means doing the eviction first requires an initial 1 cycle delay but this delay has to be applied to all misses because we don't know if an eviction is required. Since reading the demand line first is logically ok so long as it is not written to the sram until after the eviction. 2022-07-19 22:42:25 -05:00

ab9738d3be Hacky fix to prevent ITLBMissF and TrapM bug. 2022-04-12 17:56:23 -05:00
Ross Thompson
02d6829f8e Found the complex TrapM giving back the wrong instruction bug. 
As I was reviewing the busfsm I found a typo.

  assign UnCachedLSUBusRead = (BusCurrState == STATE_BUS_READY & UnCachedAccess & LSURWM[1] & IgnoreRequest) |
							  (BusCurrState == STATE_BUS_UNCACHED_READ);

It should be

  assign UnCachedLSUBusRead = (BusCurrState == STATE_BUS_READY & UnCachedAccess & LSURWM[1] & ~IgnoreRequest) |
							  (BusCurrState == STATE_BUS_UNCACHED_READ);

There is a ~ missing before IgnoreRequest. I restarted the FPGA and had it trigger on the specific faulting event.  Sure enough the bus makes an IFUBusRead, which UncachedLSUBusRead feeds into.   The specific instruction in the fetch stage had an ITLBMiss with a physical address in an unmapped area which is interpreted as an uncached operation.  IgnoreRequest is is high if there is a TrapM | ITLBMissF.  Without the & ~IgnoreRequest the invalid address translation makes the request.
