We are gradually adopting the specification, notingthat the tags are considered only advisory and do not, in any way,superceed or replace the license texts.

In the future the semantics may be extended to mean thatthe calling thread takes full ownership of the console (e.g. consoleoutput from other threads could be suspended).Inspired by: bdeMFC after: 2 months List of files: /freebsd-14.2/sys/dev/cfe/cfe_console.c Sat, 17 Dec 2011 15:08:43 +0000 Andriy Gapon <avg@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/sys/dev/cfe/cfe_console.c#e5a09273 Follow up to r225203 refining break-to-debugger run-time configurationimprovements:(1) Implement new model in previously missed at91 UART driver(2) Move BREAK_TO_DEBUGGER and ALT_BREAK_TO_DEBUGGER from opt_comconsole.h to opt_kdb.h (spotted by np)(3) Garbage collect now-unused opt_comconsole.hMFC after: 3 weeksApproved by: re (bz) List of files: /freebsd-14.2/sys/dev/cfe/cfe_console.c Sat, 27 Aug 2011 14:24:27 +0000 Robert Watson <rwatson@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/sys/dev/cfe/cfe_console.c#4cf75455 Attempt to make break-to-debugger and alternative break-to-debugger moreaccessible:(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 asappropriate boot/run-time options are set, which should improve thedebuggability of BETA kernels significantly.MFC after: 3 weeksReviewed by: kib, nwhitehornApproved by: re (bz) List of files: /freebsd-14.2/sys/dev/cfe/cfe_console.c Fri, 26 Aug 2011 21:46:36 +0000 Robert Watson <rwatson@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/sys/dev/cfe/cfe_console.c#61f7c762 Create the "cfecons" tty directly using tty_makedev(). It is not clear whatthe 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 totty_makedev() so one name of the ttys was garbage.Fix the code that calls cfe_write() to deal with the case where only a partialbuffer 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 foreverbecause cfe_cngetc() will only ever return if there is valid input.Approved by: imp (mentor) List of files: /freebsd-14.2/sys/dev/cfe/cfe_console.c Tue, 26 Jan 2010 03:42:34 +0000 Neel Natu <neel@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/sys/dev/cfe/cfe_console.c#c72a141e Fix various conolse issues with cfe after MPSAFE tty.Fix a bug with getting env on cfe...

It hasto be there, to keep drivers like syscons happy. So I'm creating atty_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.
