I have a code running in Ring0 and it is crashing. I do not have any gdb server in my software. It is pure assembly diagnostic software. I am using Corei7 In embedded systems I used a hardware debugger (with Jtag), I can stop the core and check the exception registers... I am not able to find the same process in x86 based boards. Can someone point out how they do debugging of assembly code without using gdb.... Or if you use a JTAG/HW debugger please let me know as well thanks -- To unsubscribe from this list: send the line "unsubscribe linux-x86_64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
