[lldb-dev] Remote Kernel Debugging using LLDB

[Jason Molenda via lldb-dev]

Hi, the KDK from Apple includes a README file (.txt or .html, I forget) which describes how to set up kernel debugging.  I'd start by looking at those notes.  There have also been WWDC sessions that talk about kernel debugging, e.g.

https://developer.apple.com/videos/play/wwdc2013/707/

(there are PDFs of the slides of the presentation - the lldb part comes at the end)

I have mach_kernel from KDK (kernel debug kit) and also have my own kernel extension. if I set mach_kernel a target I am not able put breakpoint in my kernel extension and if I make target as my kernel ext ..i can put breakpoint but then after hitting continue it says invalid process ..... So the question is how to proceed after connecting bebugger in panic mode??? – hrishikesh chaudhari Jul 22 at 12:52
