SPDX-License-Identifier: GPL-2.0 + +arch/riscv maintenance guidelines for developers +================================================ + +Overview +-------- +The RISC-V instruction set architecture is developed in the open: +in-progress drafts are available for all to review and to experiment +with implementations. New module or extension drafts can change +during the development process - sometimes in ways that are +incompatible with previous drafts. This flexibility can present a +challenge for RISC-V Linux maintenance. Linux maintainers disapprove +of churn, and the Linux development process prefers well-reviewed and +tested code over experimental code. We wish to extend these same +principles to the RISC-V-related code that will be accepted for +inclusion in the kernel. + +Submit Checklist Addendum +------------------------- +We'll only accept patches for new modules or extensions if the +specifications for those modules or extensions are listed as being +"Frozen" or "Ratified" by the RISC-V Foundation. (Developers may, of +course, maintain their own Linux kernel trees that contain code for +any draft extensions that they wish.) + +Additionally, the RISC-V specification allows implementors to create +their own custom extensions. These custom extensions aren't required +to go through any review or ratification process by the RISC-V +Foundation. To avoid the maintenance complexity and potential +performance impact of adding kernel code for implementor-specific +RISC-V extensions, we'll only to accept patches for extensions that +have been officially frozen or ratified by the RISC-V Foundation. +(Implementors, may, of course, maintain their own Linux kernel trees +containing code for any custom extensions that they wish.) -- cgit v1.2.3
