This series adds RISC-V PMEM support using recently added Svpbmt and Zicbom support. First two patches are fixes and remaining two patches add the required PMEM support for Linux RISC-V. These patches can also be found in riscv_pmem_v6 branch at: https://github.com/avpatel/linux.git Changes since v5: - Rebased on Linux-6.1-rc5 - Directly add pmem.o in obj-y of PATCH3 - Dropped PATCH1 since this is already merged. Changes since v4: - Simplify PATCH2 by implementing RISC-V specific arch_memremap_wb() Changes since v3: - Pickup correct version of Drew's patch as PATCH1 Changes since v2: - Rebased on Linux-6.1-rc1 - Replaced PATCH1 with the patch proposed by Drew Changes since v1: - Fix error reported by test bot https://lore.kernel.org/all/202208272028.IwrNZ0Ur-lkp@intel.com/ Anup Patel (3): RISC-V: Fix MEMREMAP_WB for systems with Svpbmt RISC-V: Implement arch specific PMEM APIs RISC-V: Enable PMEM drivers arch/riscv/Kconfig | 1 + arch/riscv/configs/defconfig | 1 + arch/riscv/include/asm/io.h | 5 +++++ arch/riscv/mm/Makefile | 1 + arch/riscv/mm/pmem.c | 21 +++++++++++++++++++++ 5 files changed, 29 insertions(+) create mode 100644 arch/riscv/mm/pmem.c -- 2.34.1
