I'm sorry for my last email, the "line break" is lost. I use KDE, Thunderbird to send email, when I copy and paste the output from Konsole, the "line break" is normal in Thunderbird editor when I see. But after I send out email, the "line break" is lost.

Yes, 64 is a better choice on loong64 architecture. The following is run on my test loong64 machine: root@klx:~# arch loongarch64 root@klx:~# uname -a Linux klx 7.0.12+deb14-loong64 #1 SMP PREEMPT Debian 7.0.12-1 (2026-06-09) loongarch64 GNU/Linux root@klx:~# cat /sys/devices/system/cpu/cpu0/cache/index0/coherency_line_size 64 I also confirm this through the Chinese Wechat group with staff in loongson company.
