Hi guys, Does anyone have any decent information on the purpose, performance potential or perhaps quirks of the "read prefetch" and "post write" buffer features on some IDE chipsets? It doesn't look like any standard but at least is included in quite a few of the libata drivers, and a lot of x86 BIOS control has toggles to try and turn it on or off. But, what is it? I've never seen any documentation but which register to use to toggle it.. no vendor recommendations to turn it on, it seems like a rather secret feature..? -- Matt Sealey <matt@xxxxxxxxxxxxxx> Genesi, Manager, Developer Relations - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
