The module will be called ufshcd. To compile this driver as a module, choose M here and read . However, do not compile this as a module if your root file system (the one containing the directory /) is located on a UFS device. config SCSI_UFSHCD_PCI tristate "PCI bus based UFS Controller support" depends on SCSI_UFSHCD && PCI ---help--- This selects the PCI UFS Host Controller Interface. Select this if you have UFS Host Controller with PCI Interface. If you have a controller with this interface, say Y or M here. If unsure, say N. config SCSI_UFS_DWC_TC_PCI tristate "DesignWare pci support using a G210 Test Chip" depends on SCSI_UFSHCD_PCI ---help--- Synopsys Test Chip is a PHY for prototyping purposes. If unsure, say N. config SCSI_UFSHCD_PLATFORM tristate "Platform bus based UFS Controller support" depends on SCSI_UFSHCD ---help--- This selects the UFS host controller support. Select this if you have an UFS controller on Platform bus. If you have a controller with this interface, say Y or M here. If unsure, say N. config SCSI_UFS_DWC_TC_PLATFORM tristate "DesignWare platform support using a G210 Test Chip" depends on SCSI_UFSHCD_PLATFORM ---help--- Synopsys Test Chip is a PHY for prototyping purposes. If unsure, say N. config SCSI_UFS_QCOM tristate "QCOM specific hooks to UFS controller platform driver" depends on SCSI_UFSHCD_PLATFORM && ARCH_QCOM select PHY_QCOM_UFS help This selects the QCOM specific additions to UFSHCD platform driver. UFS host on QCOM needs some vendor specific configuration before accessing the hardware which includes PHY configuration and vendor specific registers. Select this if you have UFS controller on QCOM chipset. If unsure, say N. config SCSI_UFS_MEDIATEK tristate "Mediatek specific hooks to UFS controller platform driver" depends on SCSI_UFSHCD_PLATFORM && ARCH_MEDIATEK select PHY_MTK_UFS select RESET_TI_SYSCON help This selects the Mediatek specific additions to UFSHCD platform driver. UFS host on Mediatek needs some vendor specific configuration before accessing the hardware which includes PHY configuration and vendor specific registers. Select this if you have UFS controller on Mediatek chipset. If unsure, say N. config SCSI_UFS_HISI tristate "Hisilicon specific hooks to UFS controller platform driver" depends on (ARCH_HISI || COMPILE_TEST) && SCSI_UFSHCD_PLATFORM ---help--- This selects the Hisilicon specific additions to UFSHCD platform driver. Select this if you have UFS controller on Hisilicon chipset. If unsure, say N. config SCSI_UFS_BSG bool "Universal Flash Storage BSG device node" depends on SCSI_UFSHCD select BLK_DEV_BSGLIB help Universal Flash Storage (UFS) is SCSI transport specification for accessing flash storage on digital cameras, mobile phones and consumer electronic devices. A UFS controller communicates with a UFS device by exchanging UFS Protocol Information Units (UPIUs). UPIUs can not only be used as a transport layer for the SCSI protocol but are also used by the UFS native command set. This transport driver supports exchanging UFS protocol information units with a UFS device. See also the ufshcd driver, which is a SCSI driver that supports UFS devices. Select this if you need a bsg device node for your UFS controller. If unsure, say N. config SCSI_UFS_FEATURE bool "UFS feature activate" depends on SCSI_UFSHCD ---help--- UFS feature activate such as hpb, tw and etc. config SCSI_UFS_HPB bool "UFSHPB" depends on SCSI_UFSHCD && SCSI_UFS_FEATURE ---help--- UFS HPB Feature Enable config SCSI_UFS_TW bool "UFSTW" depends on SCSI_UFSHCD && SCSI_UFS_FEATURE ---help--- UFS TW Feature Enable config SCSI_UFS_TW_IGNORE_GUARANTEE_BIT bool "UFSTW_IGNORE_GUARANTEE_BIT" default n depends on SCSI_UFSHCD && SCSI_UFS_FEATURE && SCSI_UFS_TW help If device not guarantee the lifetime of Turbo Write Buffer we will Ignore the guarantee bit[31] of dTurboWriteBufferLifeTimeEst for PoC. If device not guarantee the lifetime of Turbo Write Buffer and not ignore the bit So tw_mode change to disable_mode. config SCSI_SKHPB bool "Activate HPB Host-aware Performance Booster" depends on SCSI_UFSHCD help Activate or deactive SKHPB driver config SCSI_UFS_TEST_MODE bool "Samsung UFS TEST feature" depends on SCSI_UFSHCD && SCSI_UFSHCD_PLATFORM ---help--- This selects support for test mode for debugging. Select this option if this feature is needed on working. config SCSI_UFS_CRYPTO bool "UFS Crypto Engine Support" depends on SCSI_UFSHCD && BLK_INLINE_ENCRYPTION help Enable Crypto Engine Support in UFS. Enabling this makes it possible for the kernel to use the crypto capabilities of the UFS device (if present) to perform crypto operations on data being transferred to/from the device. config MTK_UFS_BLOCK_IO_LOG bool "UFS Block IO log" depends on MTK_BLOCK_TAG && SCSI_UFS_MEDIATEK default y help Enable IO trace for performance analysis and application access pattern study. Say Y if you want to have IO trace. If unsure, say N
