context_switch_frame Struct Reference

Stores the registers and PC for a context switch. More...

Detailed Description

Stores the registers and PC for a context switch.

This also defines context_switch_frame offsets for assembly language. The structure is sized to maintain 16 byte stack alignment per the ABI. https://github.com/riscv/riscv-elf-psabi-doc
