Hello all, I am Sewook Wee at Stanford University. For the research purpose, I am hacking the linux kernel (version 2.4.30) for The PPC405 in Virtex II Pro Xilinx FPGA. What I want to do is make Data Cache policy to be write-through, not write-back. I changed the DCWR Value in the arch/ppc/mm/44x_mmu.c, but seems it does not work. I hope some of you have decent idea to make it happen. Thanks. -- Sewook Wee weese@stanford.edu Computer System Laboratory Stanford University
