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.
 2021-08-23 12:24:03 -05:00
Ross Thompson
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.

a1c26a16d6 Cleaned up the linux testbench by removing old code and signals.
