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
