From b90aefa9e46c2c2628bfbf62e43b366678b9af07 Mon Sep 17 00:00:00 2001 From: jljusten Date: Thu, 26 Jul 2012 16:36:39 +0000 Subject: OvmfPkg: add support for debug console on port 0x402 This patch adds support for a debug console on the same port that is used by SeaBIOS. This makes it easier to debug OVMF, because it does not mix debug and serial output on the same device. It also makes it easier to leave some of the debug messages on even in release builds. To enable it, pass "-debugcon stdio -global isa-debugcon.iobase=0x402" to QEMU. The new mechanism is enabled by default, but a regular serial console can be chosen by adding -D DEBUG_ON_SERIAL_PORT to the build options.
