Provide block layer support for the kernel.
|
|
|
|
Disable this option to remove the block layer support from the
|
|
kernel. This may be useful for embedded devices.
|
|
|
|
If this option is disabled:
|
|
|
|
- block device files will become unusable
|
|
- some filesystems (such as ext3) will become unavailable.
|
|
|
|
Also, SCSI character devices and USB storage will be disabled since
|
|
they make use of various block layer definitions and facilities.
|
|
|
|
Say Y here unless you know you really don't want to mount disks and
|
|
suchlike.

Saying Y here will enable generic SG (SCSI generic) v4 support

for any block device.
|
|
|
|
Unlike SG v3 (aka block/scsi_ioctl.c drivers/scsi/sg.c), SG v4
|
|
can handle complicated SCSI commands: tagged variable length cdbs
|
|
with bidirectional data transfers and generic request/response
|
|
protocols (e.g. Task Management Functions and SMP in Serial
|
|
Attached SCSI).
|
|
|

This option is required by recent UDEV versions to properly

access device serial numbers, etc.

Some storage devices allow extra information to be

stored/retrieved to help protect the data. The block layer
|
|
data integrity option provides hooks which can be used by
|
|
filesystems to ensure better data integrity.

config BLK_DEV_THROTTLING

|
|
---help---
|
|
Block layer bio throttling support. It can be used to limit
|
|
the IO rate to a device. IO rate policies are per cgroup and
|
|
one needs to mount and use blkio cgroup controller for creating
|
|
cgroups and specifying per device IO rate policies.
|
|
|
|
See Documentation/admin-guide/cgroup-v1/blkio-controller.rst for more information.

|
bool "Block throttling .low limit interface support (EXPERIMENTAL)"
|
|
depends on BLK_DEV_THROTTLING
|
|
---help---
|
|
Add .low limit interface for block throttling. The low limit is a best
|
|
effort limit to prioritize cgroups. Depending on the setting, the limit
|
|
can be used to protect cgroups in terms of bandwidth/iops and better
|
|
utilize disk resource.
|
|
|
|
Note, this is an experimental interface and could be changed someday.
|
|
|
|
config BLK_CMDLINE_PARSER
|
|
bool "Block device command line partition parser"
|
|
---help---
|
|
Enabling this option allows you to specify the partition layout from
|
|
the kernel boot args. This is typically of use for embedded devices
|
|
which don't otherwise have any standardized method for listing the
|
|
partitions on a block device.
|
|
|
|
See Documentation/block/cmdline-partition.rst for more information.

|
|
|
config BLK_WBT
|
|
bool "Enable support for block device writeback throttling"
|
|
---help---
|
|
Enabling this option enables the block layer to throttle buffered
|
|
background writeback from the VM, making it more smooth and having
|
|
less impact on foreground operations. The throttling is done
|
|
dynamically on an algorithm loosely based on CoDel, factoring in
|
|
the realtime performance of the disk.
|
|

|
config BLK_CGROUP_IOLATENCY
|
|
bool "Enable support for latency based cgroup IO protection"
|
|
depends on BLK_CGROUP=y
|
|
---help---
|
|
Enabling this option enables the .latency interface for IO throttling.
|
|
The IO controller will attempt to maintain average IO latencies below
|
|
the configured latency target, throttling anybody with a higher latency
|
|
target than the victimized group.
|
|
|
|
Note, this is an experimental interface and could be changed someday.
|

|
|
---help---
|
|
Enabling this option enables the .weight interface for cost
|
|
model based proportional IO control. The IO controller
|
|
distributes IO capacity between different groups based on
|
|
their share of the overall weight distribution.
|

enabling this option is recommended.

|
|
---help---
|
|
Include block layer debugging information in debugfs. This information
|
|
is mostly useful for kernel developers, but it doesn't incur any cost
|
|
at runtime.
|
|
|
|
Unless you are building a kernel for a tiny system, you should

say Y here.
