Qinglin Pan <panqinglin00@gmail.com> says: Svnapot is a RISC-V extension for marking contiguous 4K pages as a non-4K page. This patch set is for using Svnapot in hugetlb fs and huge vmap. This patchset adds a Kconfig item for using Svnapot in "Platform type"->"SVNAPOT extension support". Its default value is on, and people can set it off if they don't allow kernel to detect Svnapot hardware support and leverage it. Tested on: - qemu rv64 with "Svnapot support" off and svnapot=true. - qemu rv64 with "Svnapot support" on and svnapot=true. - qemu rv64 with "Svnapot support" off and svnapot=false. - qemu rv64 with "Svnapot support" on and svnapot=false. * b4-shazam-merge: riscv: mm: support Svnapot in huge vmap riscv: mm: support Svnapot in hugetlb page riscv: mm: modify pte format for Svnapot Link: https://lore.kernel.org/r/20230209131647.17245-1-panqinglin00@gmail.com [Palmer: fix up the feature ordering in the merge] Signed-off-by:
