The APRP model makes it possible that one or more CPUs run the Linux kernel whereas a dedicated CPU runs special real-time or signal processing program. This patchset adds the following to the current APRP support: 1. Several bug fixes; 2. Running floating point heavy jobs on the RP side; 3. Waking up RP side read by interrupt; 4. CPS multicore APRP support. A mp3 player program was ported to run in the APRP (APSP exactly) model. Considerable performance benefits were observed on the player program. Since I encountered a sound card support issue on the current linux-mips kernel, I rebased this patchset onto mti-2.6.29.4-1. And for the current kernel, I used a simple test program to validate this work.
