Online GDB is online compiler and debugger for C/C++. You can compile, run and debug code with gdb online. Using gcc/g++ as compiler and gdb as debugger. Currently C and C++ languages are supported.
Begin by compiling the bitreverse.cu CUDA application for debugging by entering the follow- ing command at a shell prompt: $ nvcc -g -G bitreverse.cu -o bitreverse This command assumes that the source file name is bitreverse.cu and that no additional compiler flags are required for ...

这里需要开启内核参数CONFIG_DEBUG_INFO和CONFIG_GDB_SCRIPTS。GDB 提供了 Python 接口来扩展功能,内核基于 Python 接口实现了一系列辅助脚本,简化内核调试,开启CONFIG_GDB_SCRIPTS参数就可以使用了。 Kernel hacking ---> [*] Kernel debugging Compile-time checks and compiler options ---> [*] Compile the ...

If you haven't done this before, the r (run) command takes arguments that will be passed to the gdb target we specified earlier on the command line (python). So this ends up running "python cachetop.py". 9. Stepping I'll step one instruction (si, short for stepi) then inspect reg...

thread_info结构体中只剩下一个字段flags,进程描述符字段task已经删除,无法通过thread_info获取进程描述符了。 而且进程的thread_info也不再位于进程内核栈底了,而是放在了进程描述符task_struct结构体中,见提交sched/core: Allow putting thread_info into task_struct和x86: Move thread_info into task_struct,这样...
