RISC-V Adds Support For Persistent Memory Devices In Linux 6.2

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.

In addition to the persistent memory device support, RISC-V with Linux 6.2 adds ftrace support for RISC-V 32-bit (RV32), T-Head PMU support in the perf subsystem, and other small changes.

The full list of RISC-V feature patches for the Linux 6.2 kernel can be found via this pull request.
