Date: Tue, 21 Oct 2008 14:14:46 -0500 From: Jason Wessel <jason.wessel@...driver.com> To: kgdb-bugreport@...ts.sourceforge.net Cc: linux-kernel@...r.kernel.org Subject: kgdb 2.6.28 merge plans It is late in the merge window, but these are plans for the kgdb merges for 2.6.28. * The blackfin folks needed some changes to the kgdb core to allow some more flexibility * Another kgdboc I/O drivers is ready for merge * The CONSOLE_POLL API has been extended to allow for an RX poll call back from a low level serial driver * kgdboc will request/allocate a tty so as to sync with the user space with respect to having only one invocation of the low level start up code. To an end user there are a couple key differences with the enhanced kgdboc. There were numerous complaints that folks just wanted kgdboc to work like the 8250_kgdb module where gdb could just connect and it worked. This is the new default behavior of kgdboc. It will intercept a control-c or the start of a gdb serial packet and automatically jump into the debugger, much like the 8250_kgdb module. The other difference is that with the tty allocation, kgdboc can also now be configured on a non-console or inactive serial port. After this patch set is applied the only thing that kgdboc cannot currently do that the 8250_kgdb module could is perform debugging before the tty and console kernel subsystems have been initialized in the kernel. It is likely that this can be accomplished a different way in the future and the 8250_kgdb module will be deprecated and never merged to the mainline kernel. Final regression testing for these features is being completed in the next day.
