This commit was manufactured to restore the state of the 8.2-RELEASE image.
Last minute TTY API change: remove mutex argument from tty_alloc().2009-05-29T06:41:23ZEd Schoutened@FreeBSD.org2009-05-29T06:41:23Zurn:sha1:c5e30cc02b9bee4c53457d1bc4184b256ce1a569
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.
si_cmdname() is defined only when SI_DEBUG is enabled, thus2009-02-07T02:14:27ZWojciech A. Koszekwkoszek@FreeBSD.org2009-02-07T02:14:27Zurn:sha1:e54815ad40deb91ff0695c485353eaa924432dfb
using this function in simple printf() causes compile-time
problems. Use conditionally enabled DPRINT() macro instead.
Pass 1 of mpsafetty-ifying si(4). It compiles and has basic functionality,2008-09-08T11:41:20ZPeter Wemmpeter@FreeBSD.org2008-09-08T11:41:20Zurn:sha1:434cb989010e6ea6491c85003bbece79fb39bc22
but needs a lot more work. In particular, it has no flow control and has
a tendency to race when giving commands. It still uses Giant for the
tty and driver lock, but this is a keep-it-simple feature for now.
Some of the [temporary] proliferation of messages lines are way too long.
Remove sicontrol(8)'s "ttystat".2008-06-09T08:43:27ZEd Schoutened@FreeBSD.org2008-06-09T08:43:27Zurn:sha1:2ae1fdab5a78ac6d9ae9ae99ad5261a597ff83c6
In the FreeBSD base system, there are only two utilities that use struct
tty, namely pstat and sicontrol. The sicontrol utility calls the
TCSI_TTY ioctl(), which copies struct tty back to userspace.
sicontrol should not have this functionality. The same data is already
provided by pstat. If we really want to be able to export these numbers
through a file descriptor to userspace, we can export struct xtty, which
should provide a better abstraction. The ttystat option was only used as
a debugging aid.
This makes sicontrol compile in the mpsafetty branch.

builds of the PCI cards had corrected values in the configuration eeprom.

the newly added DEV_EISA. This is done so that these back-ends can
be compiled on platforms not providing in{b,w,l}()/out{b,w,l}() and
friends (but may wish to use them together with bus front-ends other
than the EISA one).
