You can disable the cache with the help of TLBs. See where it is creating TLBs for the memory regions for that processor. On Wed, Mar 14, 2012 at 8:07 AM, hellohello [off-list ref] wrote:
How to make a memory region to be cache disabled in linux? I'm porting mpc83XX from vxworks to linux. Now meet a question: Cpu use a memory region (GPCM mode of bus) to access peripherals, we need this memory to be cache disabled. Linux Kernel is 2.6.25. Thanks very much for any hint! _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
