Driver for Marvell 88SX50XX SATA interfaces (QNX Neutrino)
|You must be root to start this driver.|
devb-mvSata [cam option[,option]...] [mvSata option[,option]...] [blk option[,option]...] &
|Use commas (,) to separate the options. You can put the cam, mvSata, and blk groups of options in any order.|
The mvSata options control the driver's interface to the mvSata controller. If you've installed multiple controllers, you can repeat these options for each controller. Remember, however, to specify the mvSata keyword before each controller's set of options.
The blk options control io-blk.so. If specified, they must follow the blk keyword.
The devb-mvSata driver is for Marvell 88SX50XX SATA interfaces. It supports vendor ID 0x11ab with at least the following device IDs:
Due to a chipset limitation, CD-ROM and DVD-ROM drives aren't supported.
Detect all SATA controllers, and list all connected devices:
The devb-mvSata driver causes io-blk.so to adopt various block special devices under /dev. These devices are normally named hdn, where n is the physical unit number of the device.
This driver could also require the following shared objects:
|cam-disk.so||For hard-disk access.|
The devb-mvSata driver terminates only if an error occurs during startup, or if it has successfully forked itself upon startup because it hadn't been initially started in the background.
Unless overridden with the blk automount= option (see io-blk.so), devices are mounted as:
While there's no limit to the size of a disk or partition, I/O (i.e. the lseek(), read() and write() functions) is currently limited to 2 gigabytes per partition (or disk). This I/O limit has no effect on the partition size for mounted filesystems.
Known supported functions include:
chmod(), chown(), close(), closedir(), creat(), devctl(), dup(), dup2(), fcntl(), fpathconf(), fstat(), lseek(), mkdir(), mkfifo(), mknod(), open(), opendir(), pathconf(), read(), readdir(), readlink(), rewinddir(), rmdir(), stat(), symlink(), unlink() (not supported for directories), utime(), write()
Note that certain calls (such as pipe(), as well as read() and write() on FIFOs) may require the pipe manager.
