Plus, x86-64 binaries are not horrifically bloated like ia64. Not to mention that the amount of reengineering in compilers like gcc required to get decent performance out of it is actually sane. > sounds every bit as bad any other attempt to prolong x86.

HPET is part of one of the PCYY specs and even available on 32 bit x86, there are just not that many bug free implements yet. Since x86-64 made it part of the base platform and is testing it from launch, they actually have a chance at being debugged in the mass market versions. -ben -- Don't email: aart@kvack.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
