CONFIG_UNWINDER_ORC: ORC unwinder

General informations

The Linux kernel configuration item CONFIG_UNWINDER_ORC:

Help text

This option enables the ORC (Oops Rewind Capability) unwinder for unwinding kernel stack traces. It uses a custom data format which is a simplified version of the DWARF Call Frame Information standard.

This unwinder is more accurate across interrupt entry frames than the frame pointer unwinder. It also enables a 5-10% performance improvement across the entire kernel compared to frame pointers.

Enabling this option will increase the kernel's runtime memory usage by roughly 2-4MB, depending on your kernel config.
