b69a5b59cd DTIM works without the store delay stall. Still a bit of work remaining. The DTIM needs cleanup. 
The cache needs a bit of clean up and the chapter needs updates.
The controller needs to be updated to remove the store delay hazard for cmo instructions.

ab68a76e77 LineDirty is either the Victim Way or the Flush way dirty, but never the hitway dirty. CBO instructions require hitway dirty. However we cannot mux hitway dirty into LineDirty wihtout creating a combinational loop so we need a separate port. 2023-11-29 17:58:39 -06:00

e02d3577ec Fixed issue #412 
The root cause was DTLB miss leads to page fault exception with concurrent I$ miss.  The HPTW hits all entries in the D$ and quickly faults.  However the I$ is still waiting on the main memory.
The trap then interrupts the atomimicity of the bus fetch and breaks the next several instructions.

The simplest solution is to use CommittedF to delay Exceptions like with Interrupts.  Note this cannot happen with CommittedM.  If the ITLB misses and the D$ also need to fetch a from the bus an ITLB page fault exception will not trigger the trap until a few stages later.
