- RISC-V XIP support introduced in Linux 5.13 (2021) to execute kernel from ROM, reducing RAM usage, is being removed.
- The feature has been broken repeatedly for months, with periods of 18 months (2023), 4 months (2024), and currently 10 months.
- Developer Nam Cao authored the removal patch, citing lack of usage and testing as clear signs for retirement.
- The patch is queued for Linux 7.1, but support can be restored later if needed.
