*Note: Please adhere to [Contributing Guidelines](https://github.com/apache/nuttx/blob/master/CONTRIBUTING.md).* ## Summary In this PR, I have included several useful small tools. 1. `deadlock` same as device side deadlock detection. 2. `addr2line` convert values to backtrace, similar to addr2line on host 3. `profile` this tools is used to profiler python commands, so we can improve the performance of the tools itself. 4. `diagnose` This tool automatically search available commands and generate a json report. 5. `dmesg`: show the RAM log Several minor bug fixes are also included here to minimize merge confections. From this PR on, the nuttxgdb tool can be published as a standard python package. We can now use `py import nuttxgdb` or `source nuttx/tools/gdb/gdbinit.py` which add nuttx/tools/gdb to path and import nuttxgdb. ## Impact `__init__.py` is replaced by `gdbinit.py`. `__init__.py` is used to mark a python package ## Testing *Update this section with details on how did you verify the change, what Host was used for build (OS, CPU, compiler, ..), what Target was used for verification (arch, board:config, ..), etc. Providing build and runtime logs from before and after change is highly appreciated.* Tested on qemu: `lm3s6965-ek:qemu-flat` Config: ```patch +CONFIG_DEBUG_SYMBOLS_LEVEL="-g3" +CONFIG_RAMLOG=y +CONFIG_RAMLOG_SYSLOG=y +CONFIG_SYSLOG_DEVPATH="/dev/ttyS1" +CONFIG_SYSLOG_MAX_CHANNELS=2 ``` Run: ``` qemu-system-arm -semihosting \ -M lm3s6965evb \ -device loader,file=nuttx.bin,addr=0x00000000 \ -netdev user,id=user0 \ -nic user,id=user1 \ -serial mon:stdio -nographic -s ``` `deadlock` use the same test case in https://github.com/apache/nuttx/pull/13899 ``` (gdb) deadlock Thread 6 "" has deadlocked! holders: 6->7->8->9 (gdb) ``` `diag report` will generate a json of some of the command results . ``` (gdb) diag report Run command: Memleak Run command: DeadLock Run command: Dmesg Write report to /home/neo/projects/nuttx/nuttx/nuttx.diagnostics.json (gdb) shell cat /home/neo/projects/nuttx/nuttx/nuttx.diagnostics.json [ { "title": "Memory Leak Report", "command": "memleak", "details": "Need to set CONFIG_MM_BACKTRACE to 8 or 16 better.\n" }, { "title": "Deadlock Report", "summary": "1 deadlocks", "command": "deadlock", "deadlocks": { "6": [ "7", "8", "9" ] } }, { "title": "RAM log", "summary": "Buffer not available", "result": "info", "command": "dmesg", "message": "" } ](gdb) ``` dmesg can be tested by generate some syslog on device by `echo 123 > /dev/ttyS1` and verify on gdb: ``` (gdb) dmesg 123 (gdb) ``` -- This is an automated message from the Apache Git Service.
