I am setting uncached opertion by, change_cp0_config(CONF_CM_CMASK, CONF_CM_UNCACHED); now should the dump_tlb_all() show the "page coherency atributes" for all entries "UNCACHED" anywhere in 4GB space..is it true ? why in my case for some entries it is still showing "Cacheable, noncoherent, write-through, no write allocate" ? Best Regards, Atul
