char drivers: RAM oops/panic logger

2010-05-27T16:12:50+00:00

Ramoops, like mtdoops, can log oops/panic information but in RAM. It can be used with persistent RAM for systems without flash support. In addition, for this systems, with this driver, it's no more needed add to the kernel the mtd subsystem with advantage in footprint. It can be used in a very easy way with persistent RAM for systems without flash support. For these systems, with this driver, it is no longer required to cinlude mtd subsystem with an advantage in footprint. In addition, you can save flash space and store this information only in RAM.

tty: n_gsm line discipline

2010-05-21T16:34:29+00:00

Add an implementation of GSM 0710 MUX. The implementation currently supports - Basic and advanced framing (as either end of the link) - UI or UIH data frames - Adaption layer 1-4 (1 and 2 via tty, 3 and 4 as skbuff lists) - Modem and control messages including the correct retry process - Flow control and exposes the MUX channels as a set of virtual tty devices including modem signals. This is an experimental driver. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

tty: esp: remove broken driver

2009-12-11T23:18:03+00:00

The ESP driver has been marked broken for years. It's an old ISA device that clearly nobody cares about any more. Remove it Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

tty: bfin_jtag_comm: emulate a TTY over the Blackfin EMUDAT/JTAG interface

2009-06-11T15:51:06+00:00

The Blackfin JTAG interface has a 4 byte generic data field (EMUDAT). With a little creative thinking, we can turn this into a TTY device. Signed-off-by: Mike Frysinger Signed-off-by: Bryan Wu Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

[S390] s390/hvc_console: z/VM IUCV hypervisor console support

2008-12-25T12:39:03+00:00

This patch introduces a new hypervisor console (HVC) back-end that provides terminal access over the z/VM inter-user communication vehicle (IUCV). The z/VM IUCV communication is independent of the regular tcp/ip network and allows access even if there is no network connection between two z/VM guest virtual machines. The z/VM IUCV hypervisor console back-end helps the user to access a z/VM guest virtual machine that lacks of network connectivity; and thus, provides a "full-screen" terminal alternative to 3215/3270 terminal sessions. Use the hvc_iucv=[0..8] kernel boot parameter to specify the number of HVC terminals using a z/VM IUCV back-end. A recent version of the s390-tools package is required to establish a terminal connection to a z/VM IUCV hypervisor console back-end.

powerpc: udbg-based backend for hvc_console

2008-11-19T05:04:25+00:00

This adds a new backend for the hvc console based on the low-level udbg callbacks. This effectively implements a working runtime console in terms of the simple udbg primitives. This is kind of a hack - since udbg isn't something you really want to be using routinely - but it's really useful during bringup. This can be used to quickly implement a userspace-usable console while you're working on a proper driver for whatever console I/O device the hardware has. Or, it can be used to avoid writing a full blown tty/console driver entirely for quick-and-dirty I/O hardware that will later be replaced by something else.

CHAR: Delete old and now unused M48T35 RTC driver for SGI IP27.

It was only used by this one SGI platform which recently was converted to RTC_LIB and with RTC_LIB enabled the legacy drivers are no more selectable. Signed-off-by: Ralf Baechle
