Set proper console speed on resume if console suspend is disabled

Commit b5b82df6, from May 2007, breaks no_console_suspend on the OLPC
XO laptop. Basically what happens is that upon returning from resume,
serial8250_resume_port() will reconfigure the port for high speed
mode and all console output will be garbled, making debug of the
resume path painful. This patch modifies uart_resume_port() to
reset the port to the state it was in before we suspended.

Original patch by Marcelo Tosatti

Second patch by Deepak then reworked by Alan to fit with the tty changes
before it got submitted. Also fixed the console path to set c_i/ospeed as
some drivers require the termios fields are valid

10 years ago8250: Now honours baud rate lower bounds
Anton Vorontsov [Sat, 19 Sep 2009 20:13:20 +0000]
8250: Now honours baud rate lower bounds

A platform clock drives 8250 ports in most SOC systems, the clock
might run at high frequencies, and so it's not always possible to
downscale uart clock to a desired value.

Currently the 8250 uart driver accepts not supported baud rates, and
what is worse, it is doing this silently, and then passes not accepted
values to a new termios, so userspace has no chance to catch this kind
of errors (userspace verifies that settings were accepted by reading
back and comparing the settings).

This patch fixes the issue by passing minimum baud rate to the
uart_get_baud_rate() call, the call should take care of all bounds,
so userspace should now report:

  # stty -F /dev/ttyS0 speed 300
  115200
  stty: /dev/ttyS0: unable to perform all requested operations

p.s. uart_get_baud_rate() falls back to 9600, which still might be too
     low for some 10 GHz platforms, but that's a separate issue, and
     we can wait with fixing this till we find such a platform.

Note that it's not an issue for Y cards just for now. After
switching to tty_port_close_* et al. this will be a problem. So
add refcounting to them all.

Also proc .show doesn't take a tty reference and it should (along
with a ldisc one).

tty-ldisc: get rid of tty_ldisc_try_get() helper function

Now that the /proc/tty/ldiscs handling doesn't play games with 'struct
ldisc' any more, the only remaining user of 'tty_ldisc_try_get()' is
'tty_ldisc_get()' (note the lack of 'try').

And we're actually much better off folding the logic directly into that
file, since the 'try' part was always about trying to get the ldisc
operations, not the ldisc itself: and making that explicit inside of
'tty_ldisc_get()' clarifies the whole semantics.

10 years agotty-ldisc: make /proc/tty/ldiscs use ldisc_ops instead of ldiscs
Linus Torvalds [Mon, 3 Aug 2009 23:00:15 +0000]
tty-ldisc: make /proc/tty/ldiscs use ldisc_ops instead of ldiscs

The /proc/tty/ldiscs file is totally and utterly un-interested in the
"struct tty_ldisc" structures, and only cares about the underlying ldisc
operations.

So don't make it create a dummy 'struct ldisc' only to get a pointer to
the operations, and then destroy it.  Instead, we split up the function
'tty_ldisc_try_get()', and create a 'get_ldops()' helper that just looks
up the ldisc operations based on the ldisc number.

That makes the code simpler to read (smaller and more well-defined
helper functions), and allows the /proc functions to avoid creating that
useless dummy only to immediately free it again.

10 years agopty_write: don't do a tty_wakeup() when the buffers are full
Linus Torvalds [Fri, 18 Sep 2009 14:05:58 +0000]
pty_write: don't do a tty_wakeup() when the buffers are full

Commit ac89a9174 ("pty: don't limit the writes to 'pty_space()' inside
'pty_write()'") removed the pty_space() checking, in order to let the
regular tty buffer code limit the buffering itself.

That was all good, but as a subtle side effect it meant that we'd be
doing a tty_wakeup() even in the case where the buffers were all filled
up, and didn't actually make any progress on the write.

Which sounds innocuous, but it interacts very badly with the ppp_async
code, which has an infinite loop in ppp_async_push() that tries to push
out data to the tty.  When we call tty_wakeup(), that loop ends up
thinking that progress was made (see the subtle interactions between
XMIT_WAKEUP and 'tty_stuffed' for details).  End result: one unhappy ppp
user.

Fixed by noticing when tty_insert_flip_string() didn't actually do
anything, and then not doing any more processing (including, very much
not calling tty_wakeup()).

Chris Friesen [Wed, 12 Aug 2009 18:02:46 +0000]
[WATCHDOG] fix book E watchdog to take WDIOC_SETTIMEOUT arg in seconds

The WDIOC_SETTIMEOUT argument is supposed to be a "seconds" value.
However, the book E wdt currently treats it as a "period" which is
interpreted in a board-specific way.

This patch allows the user to pass in a "seconds" value and the driver
will set the smallest timeout that is at least as large as specified
by the user.  It's been tested on e500 hardware and works as
expected.

The patch only modifies the CONFIG_FSL_BOOKE case, the CONFIG_4xx case
is left unmodified as I don't have any hardware to test it on.
