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 consider patches for extensions that either: |=20 | - Have been officially frozen or ratified by the RISC-V Foundation, or | - Have been implemented in hardware that is widely available, per standard | Linux practice. The xventanacondops bits don't qualify under the first entry, and I don't think they qualify under the second yet.
