Found a bug in loading dep file which line contains whitespace character, e. g. vim-locale.tcz.dep.
Fixed and suggest several improvements.
Perhaps it isn't necessary to umount a empty extension? It spends more than one second checking in coreplus.

Thanks, the spaces parts and the echo/printf change applied.

Unmounting an empty extension saves a loop and the accompanied RAM, ~64kb from memory. Also the changed modules check is wrong, the majority of module extensions contain the modules in a different dir than /lib/modules.

Is there an advantage to the getbasefile change? It is called quite rarely.

Empty extension is not common, so I think it is not much significance to check, but increase boot time. But even so, the line using ls should be redundant.
In tce-setup line 182: depmod checks only /lib/modules by default? I'm not sure.
Current getbasefile is too slow, spends about 1.2s at boot time of coreplus. It only appears in tce-load and tce-update,  tce-load calls it  frequency.
In tce-load, line 249,273, F="${F##*/}" have removed the path string, so can only use %.*.

Yes, depmod also handles /usr/local/lib/modules. It's also possible the extension has modules elsewhere and copies them to either dir.

What is your test hw?

Use virtualbox. Add date "+%s.%N" to function process_CD in tce-setup.

Using find modules spends 0.5s.

Is that with virt extensions (hw accel) or sw mode?

I benched getbasefile vs the one in the patch in Qemu sw mode, it was 1.85 times faster. I'll apply that part. I agree the ls seems extra, will remove.

The modules must always be found, so the check cannot be removed.

with virt extensions.
Using find for checking is slow too :)

Yes, but is there a better option when it can be anywhere?
