I have a few questions about cachectl in HP-UX 7.05: 1) If the executable has been changed to have the cache operate in write-through mode for the data (and stack) segment, is cachectl (I_PURGE, 0, 0) then a NOP since there are no longer any dirty D-cache lines, or does it still flush the I cache? If it does not, how can I make it do that? 2) Is cachectl available for the PA machines in 8.0x ? I know about FDC/FIC, etc. but would like to flush the whole cache. I also know about FDCE/FICE and about the lack of documentation on their use.
