That won't work, will it? Your test report said that the CASID bits were set/reset by dcbi and dcbz? Did I missunderstand something? Also, the tagging procedure will require more than 2 instructions, I think. I tried to use the VALID bit in MD_EPN, but that does not work. One thing I noticed is that I can remove M_CASID and M_EVALID copy in the DTLB Error handler without any visible problems. Why are they needed?
