SceSdif is a kernel module that is primary responsible for communicating with SD devices. This includes onboard eMMC, game card MMC, wi-fi/bluetooth SDIO devices. To communicate with particular device SceSdif module uses device index (sd_ctx_index)

Device Index Type Description
0 MMC onboard eMMC
1 MMC game card
2 SDIO wi-fi/bluetooth
