There has been a proposal for 64 KiB page sizes: [RFC PATCH V1 00/11] riscv: Introduce 64K base page But this has not been merged, and it would be necessary to rebuild all binaries anyway due to the toolchain default, so this commit claims that the page size is fixed at 4096 bytes. --- sysdeps/riscv/bits/pagesize.h | 2 ++ 1 file changed, 2 insertions(+) create mode 100644 sysdeps/riscv/bits/pagesize.h diff --git a/sysdeps/riscv/bits/pagesize.h b/sysdeps/riscv/bits/pagesize.h new file mode 100644 index 0000000000..352fb732d7 --- /dev/null +++ b/sysdeps/riscv/bits/pagesize.h @@ -0,0 +1,2 @@ +#define __GLIBC_PAGE_SHIFT_MIN 12 +#define __GLIBC_PAGE_SHIFT_MAX 12
