97653e1aea Wally previously was overcounting retired instructions when they were flushed.
InstrValidM was used to control when the counter was updated.  However this is
not suppress the counter when the instruction is flushed in the M stage.

b6e2710f5d Confirmed David's changes to the interrupt code.
When a timer interrupt occurs it should be routed to the machine interrupt
pending MTIP even if MIDELEG[5] = 1 when the current privilege mode is
Machine.  This is true for all the interrupts. The interrupt should not be
masked even though it is delegated to a lower privilege.  Since the CPU
is currently in machine mode the interrupt must be taken if MIE.

Additionally added a new qemu script which pipes together all the parsing and
post processing scripts to produce the singular all.txt trace without the
massivie intermediate files.

4f3f26c5cb Switched ExceptionM to dcache to be just exceptions.
Added test bench logic to hold forces until the W stage is unstalled.

492b6f0ea4 Fixed bugs with CSR checking. The parsing algorithm was messing up the token order after the CSR token. 2021-08-13 14:53:43 -05:00

a1c26a16d6 Cleaned up the linux testbench by removing old code and signals.
Added back in the csr checking logic.
Added code to force timer, external, and software interrupts by using the expected
values from qemu's (m/s)cause registers.
Still need to prevent wally's timer interrupt.

25533bdc49 Fixed the AMO dcache bug. The subword write needs to occur before the AMO logic.
Fixed logic for trace update in the M and W stages.  The M stage should not update if there
is an instruction fault.

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

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
