Consequently, it's important that the architecture back-ends implement these portable primitives (e.g. smp_mb()) in a way that satisfies the kernel memory model so that core code doesn't need to worry about the underlying architecture for synchronisation purposes.
It seems you don't listen me. I said multiple times - MIPS implementation of SYNC_RMB/SYNC_WMB/SYNC_MB/SYNC_ACQUIRE/SYNC_RELEASE instructions matches the description of smp_rmb/smp_wmb/smp_mb/sync_acquire/sync_release from Documentation/memory-barriers.txt file.
What else do you want from me - RTL or microArch design for that? - Leonid. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
