From 7a734e7dd93b9aea08ed51036a9a0e2c9dfd8dac Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Wed, 1 Apr 2009 18:08:28 -0700 Subject: x86, setup: "glove box" BIOS calls -- infrastructure Impact: new interfaces (not yet used) For all the platforms out there, there is an infinite number of buggy BIOSes. This adds infrastructure to treat BIOS interrupts more like toxic waste and "glove box" them -- we switch out the register set, perform the BIOS interrupt, and then restore the previous state.
