Hi David, I checked in the MIPS documentation and I couldn't find relevant information about this particular way of implementation. Unfortunately in the MIPS kernel source there are no enough comments.

Other than the Linux Kernel source code, make sure you have a copy of: MD00090-2B-MIPS32PRA-AFP, the "MIPS32(r) Architecture for Programmers Volume III: The MIPS32(r) Privileged Resource Architecture" It can be downloaded from mips.com David Daney > > Thanks, > Andrei > >
