It is written on "PowerPC e500 Core Family Reference Manual, Rev. 1" document "Table 3-3. Data Access Synchronization Requirements"

that "tlbwe" command requires using CSI before and after and possibly msync.

1. In what cases should I use msync?

2. Should I use "tlbsync" instead CSI + msync after the "tlbwe" command?


Note: CSI indicates any context-synchronizing instruction (that is, sc, isync, rfci or rfi).
