if BLOCK 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" endchoice config DEFAULT_IOSCHED string default "deadline" if DEFAULT_DEADLINE default "cfq" if DEFAULT_CFQ default "noop" if DEFAULT_NOOP endmenu endif
