Linux kernel 2.6.8 on m68k. CONFIG_060_WRITETHROUGH: The 68060 generally uses copyback caching of recently accessed data. Copyback caching means that memory writes will be held in an on-chip cache and only written back to memory some time later. Saying Y here will force supervisor (kernel) accesses to use writethrough caching. Writethrough caching means that data is written to memory straight away, so that cache and memory data always agree. Writethrough caching is less efficient, but is needed for some drivers on 68060 based systems where the 68060 bus snooping signal is hardwired on. The 53c710 SCSI driver is known to suffer from this problem. See this item in context Full configuration for 2.6.8 on m68k Home   Search
