唔知點解 linux-4.1.2-gentoo 冇咗 bfq

唔知點解 linux-4.1.2-gentoo 冇咗 bfq
USE flage 己經用咗 experimental 好耐,
pf-sources 又 hang 機, 咁唯有自己 patch

用 gentoo comp kernel 係入門功課, 豉蛋吹吓 patch
dl patch sources for kernel 4.1.2
http://algo.ing.unimo.it/people/ ... patches/4.1.0-v7r8/
有 3 個 files 0001... 0002... 0003... , say,
store under dir /usr/src/bfq-4.1.0-v7r8--patch
  1. # cd /usr/src/linux
  2. # patch    --dry-run    -p1 <   ../bfq-4.1.0-v7r8--patch/0001...    <== test
  3. # patch  -p1 <   ../bfq-4.1.0-v7r8--patch/0001...    <== patch sources
  4. apply all 3 patches ...
  5. make oldconfig
  6. set bfq as default io scheduler
複製代碼
genkernel or make, 我鍾意用 genkernel, 唔洗搞一大倫出 initramfs
mod menu.lst 仲係用緊 sys-boot/grub-0.97-r12, reboot
  1. 19:17:22 ~ #   cat  /sys/block/sd[abcde]/queue/scheduler
  2. noop deadline cfq [bfq]
複製代碼
bfq 好舊嘅 demo in youtube

不過好似冇初初咁 responsive

注意:- 唔知我發乜噏瘋嘅, 千祈唔好試
