Revision 043d1e729b0fbaf2b69386fe45290b8a9a18a6a9 authored by Eugeniy Paltsev on 06 September 2017, 18:21:08 UTC, committed by Vineet Gupta on 04 October 2017, 03:36:49 UTC
DW ethernet controller on AXS10x hangs sometimes after SW reset, so add temporary quirk to reset DW ethernet controller IP core. This quirk can be removed after axs10x reset driver (see http://patchwork.ozlabs.org/patch/800273/) or simple reset driver (see https://patchwork.kernel.org/patch/9903375/) will be available in upstream.

menu "IO Schedulers"
config IOSCHED_NOOP
bool
default y
---help---
The no-op I/O scheduler is a minimal scheduler that does basic merging
and sorting. Its main uses include non-disk based block devices like
memory devices, and specialised software or hardware environments
that do their own scheduling and require only minimal assistance from
the kernel.
config IOSCHED_DEADLINE
tristate "Deadline I/O scheduler"
default y
---help---
The deadline I/O scheduler is simple and compact. It will provide
CSCAN service with FIFO expiration of requests, switching to
a new point in the service tree and doing a batch of IO from there
in case of expiry.
config IOSCHED_CFQ
tristate "CFQ I/O scheduler"
default y
---help---
The CFQ I/O scheduler tries to distribute bandwidth equally
among all processes in the system. It should provide a fair
and low latency working environment, suitable for both desktop
and server systems.
This is the default I/O scheduler.
config CFQ_GROUP_IOSCHED
bool "CFQ Group Scheduling support"
depends on IOSCHED_CFQ && BLK_CGROUP
default n
---help---
Enable group IO scheduling in CFQ.
choice
prompt "Default I/O scheduler"
default DEFAULT_CFQ
help
Select the I/O scheduler which will be used by default for all
block devices.
config DEFAULT_DEADLINE
bool "Deadline" if IOSCHED_DEADLINE=y
config DEFAULT_CFQ
bool "CFQ" if IOSCHED_CFQ=y
config DEFAULT_NOOP
bool "No-op"

default "deadline" if DEFAULT_DEADLINE
default "cfq" if DEFAULT_CFQ
default "noop" if DEFAULT_NOOP
config MQ_IOSCHED_DEADLINE
tristate "MQ deadline I/O scheduler"
default y
---help---
MQ version of the deadline IO scheduler.
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"
default n
---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
default n
---help---
Enable hierarchical scheduling in BFQ, using the blkio
(cgroups-v1) or io (cgroups-v2) controller.
