Let's add it to virtual kernel memory layout dump. As MODULES is only defined for CONFIG_64BIT, so we dump it when CONFIG_64BIT=y. eg, MODULES_VADDR - MODULES_END 0xffffffff01133000 - 0xffffffff80000000 Reviewed-by: Guo Ren Reviewed-by: Heiko Stuebner Signed-off-by: Xianting Tian --- arch/riscv/mm/init.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/arch/riscv/mm/init.c b/arch/riscv/mm/init.c index d466ec670e1f..2c4a64e97aec 100644 --- a/arch/riscv/mm/init.c +++ b/arch/riscv/mm/init.c @@ -135,6 +135,10 @@ static void __init print_vm_layout(void) (unsigned long)VMEMMAP_END); print_ml("vmalloc", (unsigned long)VMALLOC_START, (unsigned long)VMALLOC_END); +#ifdef CONFIG_64BIT + print_ml("modules", (unsigned long)MODULES_VADDR, + (unsigned long)MODULES_END); +#endif print_ml("lowmem", (unsigned long)PAGE_OFFSET, (unsigned long)high_memory); if (IS_ENABLED(CONFIG_64BIT)) {
