In past, I have played with cache locking with line by line in ARM9. There I could recall that tags and indexes are generated on basis of physical address of the data. Now in case of PLE we have the start address and number of lines to fill with. Does the PLE operation will leave some indexes empty ? Or does the PLE populate all the lines in that way with the source data address ? Do I need to start PLE for the block of size equal to that of way-size ? To ensure no lines remain empty and to ensure no line gets overwriten by other line. Appreciate your comments.
