@manawyrm cool stuff! Have you tried with kernel compression through lz4, I.e., CONFIG_KERNEL_LZ4 ? Iirc, that beat the default gzip decompression very solidly in speed. You might also want to try _ZSTD, as I suspect the lower decompression speed of that might balance with the potentially higher compression ratio.

@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
