IIUC, the usedac option enables us to stop via_no_dac() setting forbid_dac to 1. That is, someone who uses VIA bridges can use DAC with this option even if some of VIA bridges seem to be broken about DAC. I can't see how we can do the same thing with "allowdac" and "nodac" combination. -- 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/
