config MQ_IOSCHED_KYBER
tristate "Kyber I/O scheduler"
default y
---help---
The Kyber I/O scheduler is a low-overhead scheduler suitable for
multiqueue and other fast devices. Given target latencies for reads and
synchronous writes, it will self-tune queue depths to achieve that
goal.
config IOSCHED_BFQ
tristate "BFQ I/O scheduler"
---help---
BFQ I/O scheduler for BLK-MQ. BFQ distributes the bandwidth of
of the device among all processes according to their weights,
regardless of the device parameters and with any workload. It
also guarantees a low latency to interactive and soft
real-time applications. Details in
Documentation/block/bfq-iosched.txt
config BFQ_GROUP_IOSCHED
bool "BFQ hierarchical scheduling support"
depends on IOSCHED_BFQ && BLK_CGROUP
---help---
Enable hierarchical scheduling in BFQ, using the blkio
(cgroups-v1) or io (cgroups-v2) controller.
