If the boardctrl() interface is enabled, the selecting this option will also enable the BOARDIOC_MKRD command that will support creation of RAM disks from applications. menu "Buffering" config DRVR_WRITEBUFFER bool "Enable write buffer support" default n ---help--- Enable generic write buffering support that can be used by a variety of drivers. if DRVR_WRITEBUFFER config DRVR_WRDELAY int "Write flush delay" default 350 ---help--- If there is no write activity for this configured amount of time, then the contents will be automatically flushed to the media. This reduces the likelihood that data will be stuck in the write buffer at the time of power down. endif # DRVR_WRITEBUFFER config DRVR_READAHEAD bool "Enable read-ahead buffer support" default n ---help--- Enable generic read-ahead buffering support that can be used by a variety of drivers. if DRVR_WRITEBUFFER || DRVR_READAHEAD config DRVR_READBYTES bool "Support byte read method" default y if MTD_BYTE_WRITE default n if !MTD_BYTE_WRITE config DRVR_REMOVABLE bool "Support removable media" default n config DRVR_INVALIDATE bool "Support cache invalidation" default n endif # DRVR_WRITEBUFFER || DRVR_READAHEAD endmenu # Buffering source drivers/crypto/Kconfig source drivers/loop/Kconfig source drivers/can/Kconfig source drivers/i2c/Kconfig source drivers/spi/Kconfig source drivers/i2s/Kconfig source drivers/timers/Kconfig source drivers/analog/Kconfig source drivers/audio/Kconfig source drivers/video/Kconfig source drivers/bch/Kconfig source drivers/input/Kconfig source drivers/ioexpander/Kconfig source drivers/lcd/Kconfig source drivers/leds/Kconfig source drivers/mmcsd/Kconfig source drivers/modem/Kconfig source drivers/mtd/Kconfig source drivers/eeprom/Kconfig source drivers/net/Kconfig source drivers/pipes/Kconfig source drivers/power/Kconfig source drivers/rptun/Kconfig source drivers/sensors/Kconfig source drivers/serial/Kconfig source drivers/usbdev/Kconfig source drivers/usbhost/Kconfig source drivers/usbmisc/Kconfig source drivers/usbmonitor/Kconfig source drivers/wireless/Kconfig source drivers/contactless/Kconfig source drivers/1wire/Kconfig source drivers/syslog/Kconfig source drivers/platform/Kconfig source drivers/rf/Kconfig
