NAME
sdcard - SD/MMC memory card driver
DESCRIPTION
The sdcard memory card driver supports MultiMediaCard (MMC),
Secure Digital (SD), and Secure Digital High Capacity (SDHC) memory cards. It uses the blkdev(7D) service to present these cards to the system as SCSI disks on a virtual SCSI bus, creating a child device to be serviced with sd(7D).Each card appears as its own SCSI LUN. Cards are hot-
pluggable and removable. DEVICE SPECIAL FILES Disk block special file names are located in /dev/dsk. Raw file names are located in /dev/rdsk. See sd(7D). IOCTLS See dkio(7I)ERRORS
See sd(7D) and blkdev(7D). Additionally, sdcard may issue
the following warnings, which indicate a failure to identify the card as a supported type:"Unknown SD CSD version (%d)"
"Unknown MMC CSD version (%d)"
"Unknown MMCA version (%d)"
"Card type unknown" FILES Device special files for the storage device are created in the same way as those for a SCSI disk. See sd(7D) for more information. /dev/dsk/cntndnsn Block files for disks /dev/rdsk/cntndnsn Raw files for disks/kernel/drv/sdcard 32-bit ELF kernel module (x86)
/kernel/misc/amd64/sdcard 64-bit ELF kernel module (x86)
