Hello Lianbo, 2025년 10월 30일 (목) 오전 11:58, lijiang <lijiang(a)redhat.xn--com&gt;-4f21ay07k 작성: Thank you for the positive feedback. I agreed - The '4level_4k' and 5level_4k' need to be updated to print the correct base address for PMD and PTE. I will send additional patches for '4level_4k' and '5level_4k' soon after this patch is merged. Thank you again.
