Sounds interesting.

@satmandu no reason, other than the experiments haven't been done for ZSTD, but have for XZ. I'll look into it when I get time, although if you, or others can...

Yes, but the question is whether `CONFIG_MODULE_COMPRESS_ZSTD` has better boot times.

XZ. Pi4. force_turbo=0 ``` Startup finished in 8.047s (kernel) + 11.963s (userspace) = 20.010s graphical.target reached after 11.899s in userspace ``` ``` $ find /usr/lib/modules/5.15.34-v7l+/kernel/ -name "*.xz" | xargs du...

XZ. Pi4. force_turbo=0. arm_64bit=1 ``` Startup finished in 6.836s (kernel) + 10.423s (userspace) = 17.260s multi-user.target reached after 10.381s in userspace ``` ``` $ find /lib/modules/5.15.34-v8+/kernel/ -name "*.xz" | xargs...

Yes, that's my opinion. I don't think the 10% (1.6s) speed boost compensates for the 30% size increase. If a user really cared then a self-compiled kernel could be used...

As I don't use meta-raspberrypi, can you explain if that is using RpiOS as the distribution? Is it using our pre-built kernel and modules from raspberrypi/firmware or raspberrypi/rpi-firmware? Is it...

I don't seem to be seeing this on my kernel builds. modules.dep is 200K. ``` dom@buildbot:~/projects/linux$ ls -l ../modules/lib/modules/5.15.35-v7l+/ total 2508 lrwxrwxrwx 1 dom dom 24 Apr 26 15:41 build...
