Apparently, the RK3588 has a hard gzip/zlib/deflate/lz4 decompressor module.

😅

I have to admit, "i wish i could offload this to a hardware accelerator" has not been a thing i've thought when using gunzip (or unpacking gz tarballs in general).

(Like, give me a hard xz compressor ... but gunzip? lol)

(And yeah, as you can expect, the linux kernel has no support for this... atleast in upstream, i didnt check rockchip kernel, hm..)

@urja what does that soc not have?? xD

@urja I can also imagine it would be a pain to design a clean general purpose kernel-userspace interface for that.

@urja POWER9 has hardware gzip too

@urja I have. Try zgrep on a 25GB file. Takes forever.
