The RISC-V processor architecture changes were merged this week for the Linux 6.2 cycle.
While RISC-V has been seeing a lot of new kernel development in recent months, for the Linux 6.2 cycle it isn’t too particularly exciting on the end-user front. Arguably most notable is RISC-V now supporting non-volatile memory devices with the Linux 6.2 kernel. In particular, persistent memory “PMEM” support is wired up with this kernel for mapping and accessing the memory device. The RISC-V PMEM support depends upon the Svpbmt and Zicbom RISC-V extensions for handling it.
