396f697d2f Hacky fix to prevent ITLBMissF and TrapM bug. 2022-04-12 17:56:23 -05:00
Ross Thompson
70e207e010 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.

de868ef3a2 Possible fix for trap concurent with xret. Fixes the priority so trap has higher priority than either sret or mret.

- updated testbench to read from new testvectors generated by exptestbench

Notes:
MEM_WIDTH updated to be 64*3
Input numbers and output result is 64 bit number
MEM_SIZE set to 60000

Notes:

having what I believe are two adders currently

bd7343b791 Modified lsu and uncore so only 1 sww is present. The sww is in the LSU if there is a cache or dtim. uncore.sv contains the sww if there is no local memory in the LSU. This is necessary as the subword write needs the read data to be valid and that read data is not aviable in the correct cycle in the LSU if there is no dtim or cache. Muxing could be done to provide the correct read data, but it adds muxes to the critical path. 2022-02-16 15:22:19 -06:00

6d12010d02 Fixed subtle and infrequenct bug. 
Loading buildroot at 483M instructions started with a spill + ITLBMiss.  The spillsupport logic allowed transition to the second access only after the bus/cache completed the first operation.  However the BusStall was suppressed if ITLBMissF occurs resulting in the spillfsm advancing to the second operation.  Now the spill logic also takes in ITLBMissF and prevents the early transition to the second access.

Ross Thompson
c34907c95b Completed makefile updates to accelerate the generation of memfiles. There are two makefiles in the 
regression directory.  Makefile calls the submakefiles for generating elf files.
The second makefile-memfiles generates the memfiles, addr, and label files.

509a0cd3f8 Fixed bug with interlock fsm. The interlock fsm should suppress bus and cache requests by the cpu 
only at the start of a request.  Pending interrupt was used to start one of these suppressions;
however because of the way the cache's fsm was separated from the bus fsm, the cache now made requests
to the bus fsm.  On a miss with write back, the inital fetch is handled correctly.  However if an
interrupt becam pending then the the next request (eviction) made by the cache was also suppressed.
This keeps the d cache fsm stuck in the STATE_MISS_EVICT_DIRTY state as it think it has made a request
to the bus fsm, but the pending interrupt ignored the request.

The solution is to modify how cpu requests are suppressed.  Instead of relying on pending interrupt
it is better to use interrupt which will be disabled if the dcache is currently processing the evict.

0fddceffa6 Modified the mmu to not mux the lower 12 bits of the physical address and instead directly 
assign from the input non translated virtual address.  Since the lower bits never change there is
no reason to place these lower bits on a longer critical path.
The cache and lsu were previously using the lower bits from the virtual address rather than
the physical address.  This change will allow us to keep the shorter critical path and
reduce the complexity of the lsu, ifu, and cache drawings.
