So it should use > r4k_dma_cache_wback_inv_sc(), too. The R4600 _CPU_ doesn't support an l2 cache therefore the *_pc variants are being used. The l2 cache on the indy CPU module is handled by the logic on the CPU _module_; the code to deal with that is being called by the *_pc functions and is in arch/mips/sgi/kernel/indy_sc.c. Ralf |
