tty: implement BTM as mutex instead of BKL

2010-08-10T20:47:44+00:00

The tty locking now follows the rules for mutexes, so
we can replace the BKL usage with a new subsystem
wide mutex.

Using a regular mutex here will change the behaviour
when blocked on the BTM from spinning to sleeping,
but that should not be visible to the user.

Using the mutex also means that all the BTM is now
covered by lockdep.

arch/tile: core support for Tilera 32-bit chips.

2010-06-04T21:11:18+00:00

This change is the core kernel support for TILEPro and TILE64 chips.
No driver support (except the console driver) is included yet.

This includes the relevant Linux headers in asm/; the low-level
low-level "Tile architecture" headers in arch/, which are
shared with the hypervisor, etc., and are build-system agnostic;
and the relevant hypervisor headers in hv/.

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.

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

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.

[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.
