BINFMT_MISC内核模块未使用
我正在评估基于NXP IMX.8（即ARM64V8）板。评估套件带有5.10.72 Linux内核，但没有binfmt_misc内核模块。与供应商联系后，他们提供了与内核版本相匹配的所需模块。我将其放入/LIB/模块/$（UNAME -R）/KERNEL/drivers/FS/BINFMT_MISC.KO然后echo binfmt_misc＆gt;＆gt;＆gt; /etc/模块＆amp;＆amp; /sbin/depmod＆amp;＆amp; SystemCtl重新启动。
重新启动后，lsmod | GREP BINFMT显示该模块现在已加载，但“使用0”。此外，Journal ctl -u proc-sys-fs-binfmt_misc.mount带有mount的错误：/proc/proc/sys/fs/fs/binfmt_misc：Mount Point不存在。 我是我确认不存在ls -al/proc/sys/fs/binfmt_misc。
由于我无法在/proc中创建任何Dirs，因此缺少魔术可以使它起作用的是什么？
I am evaluating an NXP iMX.8 based (which is arm64v8) board. The eval kit came with a 5.10.72 Linux kernel but did not have binfmt_misc kernel module. After contacting the vendor, they provided the needed module which matches the kernel version. I placed it into /lib/modules/$(uname -r)/kernel/drivers/fs/binfmt_misc.ko then echo binfmt_misc >> /etc/modules && /sbin/depmod && systemctl reboot.
After reboot, lsmod | grep binfmt shows that the module is now loaded, but "Use By 0". Furthermore, journalctl -u proc-sys-fs-binfmt_misc.mount errors out with mount: /proc/sys/fs/binfmt_misc: mount point does not exist. which I confirm doesn't exist via ls -al /proc/sys/fs/binfmt_misc.
Since I cannot create any dirs in /proc, what is the missing magic to get this to work?

看来该模块是单独编译的，并且内核本身不是使用
config_binfmt_misc启用的，因此应创建此安装点的代码仍然被排除： https://elixir.bootlin.com/linux/linux/linux/v5.10.72/source/source/kernel/kernel/kernel/sysctl.c#l3304将BINFMT_MISC安装到其他位置并从那里使用它是可行的吗？还是向Teh供应商询问更新的内核图像？
It seems that the module was compiled separately and kernel itself was not built with
CONFIG_BINFMT_MISCenabled, therefore the code that should create this mountpoint is still excluded: https://elixir.bootlin.com/linux/v5.10.72/source/kernel/sysctl.c#L3304Maybe it is feasible to mount binfmt_misc to some other location and use it from there? Or ask Teh Vendor for updated kernel image?
如果未定义
config_binfmt_misc，则kernel/sysctl.c不会在procf中创建坐骑。拥有模块无济于事，因为它不会创建安装点。您将需要使用config_binfmt_misc = m（或y）重建内核。请参阅： https://elixir.bootlin.com/ linux/v5.16.18/source/kernel/sysctl.c＃l3367
If
CONFIG_BINFMT_MISCis not defined, kernel/sysctl.c will not create a mountpoint in procfs. Having the module does not help, since it doesn't create the mount point. You will need to rebuild the kernel withCONFIG_BINFMT_MISC=m(or Y).See: https://elixir.bootlin.com/linux/v5.16.18/source/kernel/sysctl.c#L3367
