for use:
https://www.phoronix.com/scan.php?page=news_item&px=BFQ-Queued-Linux-4.12 Additional info: * Not enabled as of 4.12.4-1 Steps to reproduce: [mitchr@mitchr-e7450 ~]$ cat /sys/block/sda/queue/scheduler noop [deadline] cfq |
This task depends upon
4.12.4-1-ARCH
% zgrep -i bfq /proc/config.gz
CONFIG_IOSCHED_BFQ=y
CONFIG_BFQ_GROUP_IOSCHED=y
It requires you to run scsi blk_mq, which is off by default in Arch because of stability problems.
