[PATCH 4/9] fb: add hooks to handle KDB enter/exit
From: Jesse Barnes <jbarnes(a)virtuousgeek.org> Add fb ops to handle enter/exit of the kernel debugger. If present, the fb core will register them with KGDB and they'll be called when the debugger is entered and exited. The new functions are responsible for switching to an appropriate debug framebuffer and restor... 5 Aug 2010 11:20

[PATCH 8/9] drm_fb_helper: Preserve capability to use atomic kms
Commit 5349ef3127c77075ff70b2014f17ae0fbcaaf199 (drm/fb: fix FBIOGET/PUT_VSCREENINFO pixel clock handling) changed the logic of when a pixclock was valid vs invalid. The atomic kernel mode setting used by the kernel debugger relies upon the drm_fb_helper_check_var() to always return -EINVAL. Until a better solu... 5 Aug 2010 11:20

[PATCH 3/9] kgdboc: Add call backs to allow kernel mode switching
Add the kms keyword processing to kgdboc and the callbacks to invoke console switching when ever kgdboc is started with "kgdboc=kms,kbd".

[PATCH 09/17] arm,kgdb: Add ability to trap into debugger on notify_die
Now that ARM implements the notify die handlers, add the ability for the kernel debugger to receive the notifications.

[PATCH 17/17] debug_core,kdb: fix crash when arch does not have single step
When an arch such as mips and microblaze does not implement either HW or software single stepping the debug core should re-enter kdb. The kdb code will properly ignore the single step operation. Attempting to single step the kernel without software or hardware support causes unpredictable kernel crashes. Signe... 5 Aug 2010 11:20

[PATCH 02/17] gdbstub: Optimize kgdb's "thread:" response for the gdb serial protocol
The gdb debugger understands how to parse short versions of the thread reference string as long as the bytes are paired in sets of two characters. The kgdb implementation was always sending 8 leading zeros which could be omitted, and further optimized in the case of non-negative thread numbers. The negative numbe... 5 Aug 2010 11:20
