Re: [Kgdb-bugreport] [PATCH 1/3] KGDB: Major refactoring

[this means a simple Ctrl-C on a kgdboc line would break into KGDB as well - but that would be an acceptable price.] Right now kgdboc just hangs when gdb attaches - i have to generate a SysRq sequence via a terminal emulator to break it into KGDB mode. FYI, even if you were to hack in a control-c vs sysrq, gdb will still hang on connect because it does not issue a break of any kind when it connects. It assumes the connection is in a usable state. sigh. That's quite a usability barrier IMHO. The proxy spliter automatically sends the break (or in the current case the sysrq g) any link to the proxy splitter? Googling for kgdb proxy splitter did not yield anything obviously on-topic.

* Jan Kiszka [EMAIL PROTECTED] wrote: As most changes are tightly coupled, this refactoring patch for KGDB_8250 as well as the core and the new KGDBOC driver comes as a single chunk. The changes are: - Reorganized configuration: I/O drivers can be independently configured as module or built-in - Dynamic reconfiguration for KGDB_8250 (just like for KGDBOC) - Reworked KGDB_8250 configuration string format - attachwait removed, arming the debugger via assigning an I/O driver implies attachwait - Cleaned up I/O driver managment of the core - Matured the various boot-up, configure, unconfigure code paths for both I/O drivers - IRQ vs. KGDB_CONSOLE-output SMP race fixed for KGDB_8250 - Reduced and cleaned up hooks into serial_core/8250 - Kconfig cleanups great stuff! I've picked these cleanups up into x86.git.

This would make kgdboc way more practical without having to resort to a protocol splitting proxy, etc. Ingo - This SF.net email is sponsored by: Microsoft Defy all challenges.

I started the 2.6.25 branch with all Ingo's changes, your changes and several additional patches I received. http://git.kernel.org/?p=linux/kernel/git/jwessel/linux-2.6-kgdb.git;a=summary Thanks, Jason. - This SF.net email is sponsored by: Microsoft Defy all challenges.
