MFC: r207533 (partial)

2010-05-10T20:15:39Z

Remove redundant checking of sc_leaving (uart_intr() already handles this).

Support the tablet in (at least) the Toshiba Portege M200 Tablet PC. This device only appears on the ACPI bus, so isn't caught by the current entry for it in the uart(4) ISA attachment. PR: kern/140172 Reviewed by: jhb, marcel Approved by: ed (mentor, implicit)

Add support for the NetMos NM9865 family of Serial/Parallel ports.

MFC change 197721:

2009-10-10T18:24:54Z

Fix RTS/CTS flow control, broken by the TTY overhaul. The new TTY interface is fairly simple WRT dealing with flow control, but needed 2 new RX buffer functions with "get-char-from-buf" separated from "advance-buf-pointer" so that the pointer could be advanced only when ttydisc_rint() succeeded.

Fix serial console on Apple Xserve G5 by falling back to input-device-1

if input-device is unavailable. The Xserve G5 defaults to using screen/keyboard for output-device/input-device even if these are not installed, and then falls back to serial ports at boot time. Reviewed by: marcel Hardware from: grehan Approved by: re (kib)

Move the memory layout definitions and logic from mvreg.h to mvwin.h

so that it isn't exposured unless needed. In particular this means that it's easier to tune the memory layout based on board details. While here, remove inclusion of from mvreg.h. This also contains exposure to SoC specifics in MI drivers, because NIRQ depends on the SoC.

Last minute TTY API change: remove mutex argument from tty_alloc().

2009-05-29T06:41:23Z

I don't want people to override the mutex when allocating a TTY. It has to be there, to keep drivers like syscons happy. So I'm creating a tty_alloc_mutex() which can be used in those cases. tty_alloc_mutex() should eventually be removed. The advantage of this approach, is that we can just remove a function, without breaking the regular API in the future.

Don't use pmap_kextact() when comparing bus handles for Book-E.

2009-04-08T22:19:39Z

We typically wire translation to devices with TLB1 entries and pmap_kextract() does not know about those and returns 0. This causes false positives (read: all serial ports suddenly become the console).
