Transparent Huge Pages
Transparent Huge Page support for MIPS is currently under development. THP is currently planned to only be available for 64-bit kernels. A git tree contains the development code.
Only R4000-style TLBs are supported. R8000 support may be added in the distant future. The NEC VR41xx processors have such a TLB but do not support the necessary huge page size not even for 4kB base page size so huge page support is not possible for them.
