From dcd83aaff1c8cbd5b48c152b559e0af3ea1a7b65 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Fri, 8 Jul 2011 19:06:12 -0500 Subject: tty/powerpc: introduce the ePAPR embedded hypervisor byte channel driver The ePAPR embedded hypervisor specification provides an API for "byte channels", which are serial-like virtual devices for sending and receiving streams of bytes. This driver provides Linux kernel support for byte channels via three distinct interfaces: 1) An early-console (udbg) driver. This provides early console output through a byte channel. The byte channel handle must be specified in a Kconfig option. 2) A normal console driver. Output is sent to the byte channel designated for stdout in the device tree. The console driver is for handling kernel printk calls. 3) A tty driver, which is used to handle user-space input and output. The byte channel used for the console is designated as the default tty.
