@funkylab I‘ve played around with kernel compression, but the extra energy required to decompress the kernel is harmful in my application.
In a less power constrained application, there might be some benefit, yeah!
A hardcore solution would be to write a custom minimal bootloader to move the kernel load away from the GPU and onto the CPU.
I‘m not _that_ desperate yet, but it might help :)

@manawyrm that's why I ask: lz4 decompression is (at least on x86) *so* much faster that it's hard for me to imagine it using the same energy as gzip decompression! But if your tests show that's not the case, then my takeaway is that more hardware-compatible unpackers really are faster by giving the CPU fewer opportunities to do nothing and hence run with less power. Nice lesson!

@manawyrm @funkylab I'm guessing you tried U-Boot and it didn't help?
