The Linux NVDIMM PEM drivers require arch support to map and access the persistent memory device. This series adds RISC-V PMEM support using recently added Svpbmt and Zicbom support.
These patches can also be found in riscv_pmem_v2 branch at: https://github.com/avpatel/linux.git
Changes since v1: - Fix error reported by test bot https://lore.kernel.org/all/202208272028.IwrNZ0Ur-lkp@intel.com/
Anup Patel (4): RISC-V: Fix ioremap_cache() and ioremap_wc() for systems with Svpbmt RISC-V: Move riscv_init_cbom_blocksize() to cacheflush.c RISC-V: Implement arch specific PMEM APIs RISC-V: Enable PMEM drivers
