tty: handle VT specific compat ioctls in vt driver

2009-09-19T20:13:35+00:00

The VT specific compat_ioctl handlers are the only ones
in common code that require the BKL. Moving them into
the vt driver lets us remove the BKL from the other handlers
and cleans up the code.

serial: move port users helper

2009-09-19T20:13:32+00:00

This little helper is now tty_port specific and useful generally so move it

serial: move delta_msr_wait into the tty_port

2009-09-19T20:13:31+00:00

This is used by various drivers not just serial and can be extracted
as commonality

tty: Add a full port_close function

2009-09-19T20:13:20+00:00

Now we are extracting out methods for shutdown and the like we can add a
proper tty_port_close method that knows all the innards of the tty closing
process and hides the lot from the caller.

At some point in the future this will be paired with a similar open()
helper and the drivers can stick to hardware management.

cleanup console_print()

2009-09-15T00:41:42+00:00

console_print() is an old legacy interface mostly unused in the entire
kernel tree. It's best to clean up its existing use and let developers
use their own implementation of it as they feel fit.

TTY: Add definition of a new line discipline required by Amstrad E3 (Delta) ASoC driver

2009-07-31T21:38:44+00:00

This patch adds new line discipline name an number to include/linux/tty.h. The
line discipline will be used by the Amstrad E3 (Delta) sound driver that will
come next in this series of patches.

Created against linux-2.6.31-rc3.
Applies to linux-omap-2.6 commit 7c5cb7862d32cb344be7831d466535d5255e35ac as

pty: avoid forcing 'low_latency' tty flag

2009-07-29T19:15:56+00:00

We really don't want to mark the pty as a low-latency device, because as
Alan points out, the ->write method can be called from an IRQ (ppp?),
and that means we can't use ->low_latency=1 as we take mutexes in the
low_latency case.

So rather than using low_latency to force the written data to be pushed
to the ldisc handling at 'write()' time, just make the reader side (or
the poll function) do the flush when it checks whether there is data to
be had.

This also fixes the problem with lost data in an emacs compile buffer
(bugzilla 13815), and we can thus revert the low_latency pty hack
(commit 3a54297478e6578f96fd54bf4daa1751130aca86: "pty: quickfix for the
pty ENXIO timing problems").
