Configuring the HP Processor Probe for PowerPC 603/603e
Processor Memory Cache Configuration Items
cf imwrop=inv_dcu
This stands for instruction cache invalidate and data cache update. An
instruction memory write will invalidate the instruction cache if valid and
write to physical memory. The data cache will also be updated if the address
is valid in the data cache.
N o t e
Setting imwrop to upd_dcb or inv_dcb should be used with caution since
dirty cache entrys in the data cache may overwrite the memory just modified
by the HP processor probe.
Default: cf imwrop=upd_dcu
