Got it, thanks. I actually went to read the 4xx errata this time instead of just blindly accepting the patch as I did last time. There are some other nasty things we should consider fixing. The worst is #67, and now they have told us about #77 so we can fix up the ATOMIC_SYNC_FIX.... Of all the errata, #77 is the only one we have seen with Linux. I guess you could force #51 to occur, but whether you call ITLBmiss or DTLBmiss probably doesn't matter because they end up at the same place. We are somewhat lucky with #67 because I don't think we have mapping situations where this can occur. Although, some days I read it and think otherwise..... -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
