Analyze a kernel Oops from the printk buffer in a PearPC memory dump

安装方式

默认使用会先检查来源的 Prompt；你也可以切换为直接命令，或下载本地副本。

用 Codex 或 Claude 帮你安装复制这段 Prompt，粘贴到 Codex、Claude 或其他助手里，让它检查 Skill 页面并帮你完成安装。

直接命令不会经过审查 Prompt；运行前请先检查来源。

Use scripts/debug/memdump.py to extract and analyze the Oops.

Extract the Oops:

python3 scripts/debug/memdump.py oops ${ARGUMENTS:-memdump_jit.bin}

Decode pt_regs (use the REGS address from the Oops output):

python3 scripts/debug/memdump.py regs DUMP_FILE REGS_ADDRESS

Disassemble around NIP and LR (convert VA to PA: PA = VA - 0xC0000000):

python3 scripts/debug/disasm_ppc.py DUMP_FILE PA_OF_NIP 16
python3 scripts/debug/disasm_ppc.py DUMP_FILE PA_OF_LR 16

Search for the NIP value in both dumps:

python3 scripts/debug/memdump.py find memdump_generic.bin NIP_VALUE
python3 scripts/debug/memdump.py find memdump_jit.bin NIP_VALUE

Check if NIP is a valid address:
- 0xC0xxxxxx = kernel code
- 0xBFxxxxxx = PROM virtual address (prom_mem_phys_to_virt)
- 0xFDxxxxxx = PCI I/O space (not executable)

Report: exception type, faulting address, caller, what the code was trying to do.
