Hi all I notice we have hibernation.c in arm/kernel, however, I don't find it in arm64. Does it mean arm64 do not support hibernation/suspend-to-disk function? I tried some path to search the reason, but found nothing, they all say arm64 has the backward compatibility. So I send this email to the community and hope to get the reason. Thanks! I ported the arm hibernation.c to arm64/kernel(with LP64), but failed in a strange way. When I do resume, the arch_restore_image() get a page_fault when it calls the copy_page(), like: "Unable to handle kernel paging request at virtual address 0xffffffbc055c3fa8" I'm sure the copy_page()'s parameters is in the memory area, why and how I get the strange address 0xffffffbc055c3fa8? vmalloc: 0xffffff8000000000 - 0xffffffbb00000000 vmemmap: 0xffffffbc01400000 - 0xffffffbc04f88000 modules: 0xffffffbffc000000 - 0xffffffc000000000 memory: 0xffffffc000000000 - 0xffffffc0be800000 Look forward to your reply, thanks! -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
