Heck the algo was originally designed based on another compression algorithm, but for a 6502 packer. I aimed at speed, simplicity, and minimal RAM usage (hint: it used 4k for the code AND the compressed data on a 6502, 336 bytes for code, and if I turn it into just a straight packer I can go under 200 bytes on the 6502). Honestly, I just never looked. I look in my kernel. But still, the stuff I defined about swapon options, swap-on-ram, and how the compression works (yes, compressed without headers) is all the detail you need about it to go do it AFAIK. Preplanning should be done there--done meaning workable, not "the absolute best." --Bluefox Icy ---- ORIGINAL MESSAGE ---- List: linux-kernel Subject: Re: Swap Compression From: John Bradford Date: 2003-04-25 21:17:11 [Download message RAW] > Sorry if this is HTML mailed.
