grub.cfg에서 격리된 코어를 설정하는 방법은 무엇입니까?

CPU2사용자 정의된 Linux 시스템에서 격리를 설정했지만 재부팅한 후에도 여전히 를 grub.cfg사용하는 사용자 공간 프로세스가 많이 있음을 발견 CPU2했습니다 sshd. top문제가 무엇입니까?

그럽.cfg:

# Begin cfg
set default=0
set timeout=3

#set root=(hd0,gpt3)

menuentry "GNU/Linux, Dobot-6.4.0-rt8" {
    linux (hd0,gpt2)/bzImage rw root=/dev/mmcblk0p3 net.ifname-policy=onboard,path,slot
    initrd (hd0,gpt2)/initrd.img-6.4.0-rt8
    GRUB_CMDLINE_LINUX_DEFAULT="isolcpus=2"
}

게다가 결과 GRUB_CMDLINE_LINUX_DEFAULT="quiet splash isolcpus=2"도 /etc/default/grub마찬가지다.

단일 결과 top:
