From c98d748e8dea511ddf9bb3de45447ec3c2083149 Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Tue, 26 Jul 2011 20:14:37 +1000 Subject: [PATCH] Linux supports some optional features, but it should notify the BIOS about them via the _OSI method. Currently Linux doesn't notify any, which might make such features not work because the BIOS doesn't know about them. Jarosz has a system which needs this to make ACPI processor aggregator device work.
