It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

Some of this could be fixed by moving it to attach(), but some requires something more subtle than BUS_PROBE_NOWILDCARD. 2011-12-17T15:08:43Z Andriy Gapon avg@FreeBSD.org 2011-12-17T15:08:43Z urn:sha1:9976156f12f1be7cb85c90e9ef54be06690bc955 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).

(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.

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. Approved by: imp (mentor)
