pty: simplify resize

2009-01-02T18:19:36Z

We have special case logic for resizing pty/tty pairs. We also have a per driver resize method so for the pty case we should use it. Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

Add an instance parameter devpts interfaces

2008-10-13T16:51:43Z

Pass-in 'inode' or 'tty' parameter to devpts interfaces. With multiple devpts instances, these parameters will be used in subsequent patches to identify the instance of devpts mounted. The parameters also help simplify devpts implementation. Changelog[v3]: - minor changes due to merge with ttydev updates - rename parameters to emphasize they are ptmx or pts inodes - pass-in tty_struct * to devpts_pty_kill() (this will help cleanup the get_node() call in a subsequent patch) Signed-off-by: Sukadev Bhattiprolu Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

tty: More driver operations

2008-10-13T16:51:42Z

We have the lookup operation abstracted which is nice for pty cleanup but we really want to abstract the add/remove entries as well so that we can pull the pty code out of the tty core and create a clear defined interface for the tty driver table.

tty: Clean up the tty_init_dev changes further

2008-10-13T16:51:42Z

Fix up the naming, style and extract some bits of code into the driver specific code Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

tty: shutdown method

2008-10-13T16:51:42Z

Right now there are various drivers that try to use tty->count to know when they get the final close. Aristeau Rozanski showed while debugging the vt sysfs race that this isn't entirely safe. Instead of driver side tricks to work around this introduce a shutdown which is called when the tty is being destructed. This also means that the shutdown method is tied into the refcounting. Use this to rework the console close/sysfs logic. Remove lots of special case code from the tty core code. The pty code can now have a shutdown() method that replaces the special case hackery in the tree free up paths. Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

tty: Add termiox

2008-10-13T16:51:40Z

We need a way to describe the various additional modes and flow control features that random weird hardware shows up and software such as wine wants to emulate as Windows supports them. TCGETX/TCSETX and the termiox ioctl are a SYS5 extension that we might as well adopt. This patches adds the structures and the basic ioctl interfaces when the TCGETX etc defines are added for an architecture. Drivers wishing to use this stuff need to add new methods.

tty: remove resize window special case

2008-08-15T17:34:07Z

This moves it to being a tty operation. That removes special cases and now also means that resize can be picked up by um and other non vt consoles which may have a resize operation. Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

tty: rework break handling

2008-07-22T20:03:28Z

Some hardware needs to do break handling itself and may have partial support only. Make break_ctl return an error code. Add a tty driver flag so you can indicate driver hardware side break support. Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

tty_driver: Update required method documentation

2008-06-23T17:36:47Z

Some of the requirement rules are now more relaxed. Also correct a contradiction in the previous update Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds
