| description | Extract and display the Linux kernel printk ring buffer from a PearPC memory dump |
Use scripts/debug/memdump.py printk to extract the printk ring buffer.
python3 scripts/debug/memdump.py printk $ARGUMENTS
If no arguments, use memdump_jit.bin. Report the last printk message, any Oops, and what boot stage was reached.
Check that aarch64 JIT interpreter functions match generic CPU behavior
Analyze jitc.log to find JIT compilation issues — fragment gaps, branch overflow, bad codegen
Analyze a kernel Oops from the printk buffer in a PearPC memory dump
Analyze the JIT dispatch trace to diagnose boot stalls or crashes
Compare memory regions between generic and JIT memory dumps to find divergences
