linux-toradex.git/arch/x86/boot/bioscall.S, branch v3.2.8 Linux kernel for Apalis and Colibri modules x86, boot: use .code16gcc instead of .code16 2009-06-17T00:47:32+00:00 H. Peter Anvin hpa@zytor.com 2009-06-17T00:39:04+00:00 28b4868820a56de661f54742ff91b78e12f1e582 Use .code16gcc to compile arch/x86/boot/bioscall.S rather than .code16, since some older versions of binutils can't generate 32-bit addressing expressions (67 prefixes) in .code16 mode, only in .code16gcc mode.

x86, setup: "glove box" BIOS calls -- infrastructure 2009-04-09T23:08:11+00:00 H. Peter Anvin hpa@linux.intel.com 2009-04-02T01:08:28+00:00 7a734e7dd93b9aea08ed51036a9a0e2c9dfd8dac 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.
