quick question for CONFIG_MIPS_UNCACHED...

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,
In order to confirm a cache problem is it sufficient to set
"CONFIG_MIPS_UNCACHED" , as in so many places functions to
operate on cache are called directly while they should under
"#ifdef CONFIg_MIPS_UNCACHED" if not technically then atleast
for consistent coding practice.

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
