Hi Ralf, >>Currently only 16kB works and only for 64-bit kernels. I'm planning to >> fix that rsn. Thanks for the info, did u mean 16KB would be supported for 32 bit kernel also. I also saw code changes in arch/mips/mm/tlb-r8k.c only, is there a plan to port it to r4k TLB also. Help on 2.6.14 and 2.6.17 kernels provide the below info. Does it mean some changes are required at user level also. config PAGE_SIZE_16KB help Note that you will need a suitable Linux distribution to support this. There are also issues with compatibility of user applications Thanks Hemanth
