structures

tty/serial: lay the foundations for the next set of reworks

2008-04-30T15:29:45+00:00

- Stop drivers calling their own flush method indirectly, it obfuscates code
  and it will change soon anyway

- A few more lock_kernel paths temporarily needed in some driver internal
  waiting code

- Remove private put_char method that does a write call for one char - we
  have that anyway

- Most but not yet all of the termios copy under lock fixing (some has other
  dependencies to follow)

- Note a few locking bugs in drivers found in the process

- Kill remaining [ab]users of TIOCG/SSOFTCAR in the driver, these must go to
  fix the termios locking

drivers: Remove unnecessary inclusions of asm/semaphore.h

2008-04-19T02:16:32+00:00

None of these files use any of the functionality promised by
asm/semaphore.h.  It's possible that they rely on it dragging in some
unrelated header file, but I can't build all these files, so we'll have
fix any build failures as they come up.

genericserial: remove bogus optimisation check and dead code paths

2007-07-16T16:05:51+00:00

We've been using the 'new locking' for a long time now so it seems
pointless keeping the old one around.  Remove it and undo the macros it
uses back into real code for readability.  Remove the bogus 'no termios
change' checks.

[PATCH] generic_serial: fix decoding of baud rate

2007-03-27T16:05:15+00:00

Commit d720bc4b8fc5d6d179ef094908d4fbb5e436ffad partially removed a
private implementation of baud speed decoding.  However it doesn't seem
to be complete: after the speed is decoded, it is still being used as an
index to a local speed table (array overrun, no doubt).

This was found by Graham Murray who noticed it caused a 2.6.19 regression
with the SX driver: https://bugs.gentoo.org/170554

[PATCH] Char: tty_wakeup cleanup

2007-02-11T18:51:26+00:00

tty_wakeup cleanup

- remove wake_up_interruptible(&tty->write_wait) surrounding
  tty_wakup(tty);
- substitute tty->ldisc.write_wakeup(tty) + wake_up() by tty_wakeup(tty);

[PATCH] tty: switch to ktermios

2006-12-08T16:28:57+00:00

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

[PATCH] char: kill unneeded memsets

2006-10-04T14:55:13+00:00

char, another tmp_buf cleanup

No need to allocate one page as a side buffer.  It's no more used.  Clean this
(de)allocs of this useless memory pages in char subtree.
