From d8670d8eeb55bc0ea347cfe4a9a27640fe4e4e7e Mon Sep 17 00:00:00 2001 From: Felix Morgner Date: Mon, 4 May 2026 19:40:01 +0200 Subject: debug: add multiboot2 information dump tool This patch introduces a new GDB tool `dump_mb2i` that dump the multiboot2 information provided by the bootloader. This tool can be invoked in the GDB console. For example in vscode: -exec dump_mb2i ((kapi::boot::information)bootstrap_information).mbi The tool expects the address of the loader provided MB2 information as its only argument. --- scripts/gdb/pretty_printers.py | 41 ----------------------------------------- 1 file changed, 41 deletions(-) delete mode 100644 scripts/gdb/pretty_printers.py (limited to 'scripts/gdb/pretty_printers.py') diff --git a/scripts/gdb/pretty_printers.py b/scripts/gdb/pretty_printers.py deleted file mode 100644 index c209328..0000000 --- a/scripts/gdb/pretty_printers.py +++ /dev/null @@ -1,41 +0,0 @@ -import sys -import os -import gdb -import importlib.util - -script_path = os.path.abspath(__file__) -script_root = os.path.dirname(script_path) -repo_root = os.path.dirname(os.path.dirname(script_root)) - -if script_root not in sys.path: - sys.path.insert(0, script_root) - -components = { - "kstd": "libs/kstd/gdb", - "kapi": "kapi/gdb", -} - -for component, path in components.items(): - full_path = os.path.join(repo_root, *path.split("/")) - init_file = os.path.join(full_path, "__init__.py") - - if os.path.isfile(init_file): - try: - spec = importlib.util.spec_from_file_location(component, init_file) - module = importlib.util.module_from_spec(spec) - sys.modules[component] = module - spec.loader.exec_module(module) - - if hasattr(module, "register_printers"): - module.register_printers(gdb.current_objfile()) - gdb.write(f"Info: Registered pretty printers for '{component}'.\n") - else: - gdb.write( - f"Warning: '{component}' does not have 'register_printers' function\n" - ) - except Exception as e: - gdb.write(f"Warning: Failed to load '{component}' pretty printers: {e}\n") - else: - gdb.write(f"Warning: GDB extension init not found: '{init_file}'\n") - -gdb.write("Info: Loaded TeachOS pretty printers.\n") -- cgit v1.2.3
