2020-04-17tty: convert tty_lock_assert to tty_assert_locked to hide lock typeKyle Evans
A later change, currently being iterated on in D24459, will in-fact change the lock type to an sx so that TTY drivers can sleep on it if they need to. Committing this ahead of time to make the review in question a little more palatable. tty_lock_assert() is unfortunately still needed for now in two places to make sure that the tty lock has not been recursed upon, for those scenarios where it's supplied by the TTY driver and possibly a mutex that is allowed to recurse.

2020-01-02sys/dev/cfi: include sys/types.h as wellKyle Evans
This will soon be a dependency for machine/atomic.h on mips with the introduction of 64-bit atomics; the scope here is pretty narrow, so throw it here in the header just before systm.h, which includes machine/atomic.h Notes: svn path=/head/; revision=356301
2017-11-27sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni
Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255

2011-12-17kern cons: introduce infrastructure for console grabbing by kernelAndriy Gapon
At the moment grab and ungrab methods of all console drivers are no-ops. Current intended meaning of the calls is that the kernel takes control of console input. In the future the semantics may be extended to mean that the calling thread takes full ownership of the console (e.g. console output from other threads could be suspended).

2011-08-26Attempt to make break-to-debugger and alternative break-to-debugger moreRobert Watson
accessible: (1) Always compile in support for breaking into the debugger if options KDB is present in the kernel. (2) Disable both by default, but allow them to be enabled via tunables and sysctls debug.kdb.break_to_debugger and debug.kdb.alt_break_to_debugger. (3) options BREAK_TO_DEBUGGER and options ALT_BREAK_TO_DEBUGGER continue to behave as before -- only now instead of compiling in break-to-debugger support, they change the default values of the above sysctls to enable those features by default. Current kernel configurations should, therefore, continue to behave as expected. (4) Migrate alternative break-to-debugger state machine logic out of individual device drivers into centralised KDB code. This has a number of upsides, but also one downside: it's now tricky to release sio spin locks when entering the debugger, so we don't. However, similar logic does not exist in other device drivers, including uart. (5) dcons requires some special handling; unlike other console types, it allows overriding KDB's own debugger selection, so we need a new interface to KDB to allow that to work. GENERIC kernels in -CURRENT will now support break-to-debugger as long as appropriate boot/run-time options are set, which should improve the debuggability of BETA kernels significantly.

CFE environment variables. Notes: svn path=/head/; revision=211158
2010-01-26Create the "cfecons" tty directly using tty_makedev(). It is not clear whatNeel Natu
the intention of having two ttys pointing to the same cfe console device was. Also we were not initializing the output[] array passed in as input to tty_makedev() so one name of the ttys was garbage. Fix the code that calls cfe_write() to deal with the case where only a partial buffer is written out. cfe_cngetc() needs to return if there is no character available as input. If we don't do this then the cfe_timeout() function will spin forever because cfe_cngetc() will only ever return if there is valid input.

2009-05-29Last minute TTY API change: remove mutex argument from tty_alloc().Ed Schouten
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. Notes: svn path=/head/; revision=193018
