2009-01-02tty_port: Add a port level carrier detect operationAlan Cox
This is the first step to generalising the various pieces of waiting logic duplicated in all sorts of serial drivers. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-07-20gs: use tty_portAlan Cox
Switch drivers using the old "generic serial" driver to use the tty_port structures Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2006-12-08[PATCH] tty: switch to ktermiosAlan Cox
This is the grungy swap all the occurrences in the right places patch that goes with the updates. At this point we have the same functionality as before (except that sgttyb() returns speeds not zero) and are ready to begin turning new stuff on providing nobody reports lots of bugs If you are a tty driver author converting an out of tree driver the only impact should be termios->ktermios name changes for the speed/property setting functions from your upper layers. If you are implementing your own TCGETS function before then your driver was broken already and its about to get a whole lot more painful for you so please fix it 8) Also fill in c_ispeed/ospeed on init for most devices, although the current code will do this for you anyway but I'd like eventually to lose that extra paranoia [akpm@osdl.org: bluetooth fix] [mp3@de.ibm.com: sclp fix] [mp3@de.ibm.com: warning fix for tty3270] [hugh@veritas.com: fix tty_ioctl powerpc build] [jdike@addtoit.com: uml: fix ->set_termios declaration] Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Martin Peschke <mp3@de.ibm.com> Acked-by: Peter Oberparleiter <oberpar@de.ibm.com> Cc: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Jeff Dike <jdike@addtoit.com> Cc: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-03-23[PATCH] sem2mutex: serial ->port_write_mutexIngo Molnar
Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-03-28[PATCH] generic-serial cli() conversionPatrick vd Lageweg
This patch converts all save_flags/restore_flags to the new spin_lock_irqsave/spin_unlock_irqrestore calls, as well as some other 2.6.X cleanups. This prepares the way for the "io8+", "sx" and "rio" drivers to become SMP safe. Patches for those drivers follow.

2005-03-13[PATCH] generic_serial.h: kill incorrect gs_debug referenceAdrian Bunk
generic_serial.h contained an incorrect extern reference to the static variable gs_debug (Benoit Boissinot reported that gcc 4.0 rejects this). Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-01-07[PATCH] small char/generic_serial.c cleanupAdrian Bunk
The patch below does the following changes to drivers/char/generic_serial.c : - make two needlessly global functions static - remove the completely unused EXPORT_SYMBOL'ed function gs_do_softint AFAIR the latter should be safe, since drivers are moving away from generic_serial.c.

2004-10-20Update tty layer to not mix kernel and user pointers.Linus Torvalds
Instead, tty_io.c will always copy user space data to kernel space, leaving the drivers to worry only about normal kernel buffers. No more "from_user" flag, and having the user copy in each driver. This cleans up the code and also fixes a number of locking bugs.
2004-07-30[PATCH] sparse: drivers/char/*Alexander Viro
the rest of BROKEN_ON_SMP drivers in drivers/char sparsified. Signed-off-by: Al Viro <viro@parcelfarce.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2003-06-11[PATCH] tty_driver refcountingAlexander Viro
killed the last remnants of callout stuff - we don't need to mess with storing termios privately anymore.
