That is called "indirect" IO due to - the double handling of data. There are two methods offered to remove the - redundant copy: 1) direct IO and 2) using the mmap() system call to map - the reserve buffer (this driver has one reserve buffer per fd) into the - user space. Both have their advantages. - In terms of absolute speed mmap() is faster. If speed is not a concern, - indirect IO should be fine. Read the documentation for more information. - - ** N.B. To use direct IO 'echo 1 > /proc/scsi/sg/allow_dio' or - 'echo 1 > /sys/module/sg/parameters/allow_dio' is needed. - That attribute is 0 by default. ** - - Historical note: this SCSI pass-through driver has been known as "sg" for - a decade. In broader kernel discussions "sg" is used to refer to scatter - gather techniques. The context should clarify which "sg" is referred to. - - Documentation - ============= - A web site for the SG device driver can be found at: - http://www.torque.net/sg [alternatively check the MAINTAINERS file] - The documentation for the sg version 3 driver can be found at: - http://www.torque.net/sg/p/sg_v3_ho.html - This is a rendering from DocBook source [change the extension to "sgml" - or "xml"]. There are renderings in "ps", "pdf", "rtf" and "txt" (soon). - The SG_IO ioctl is now found in other parts kernel (e.g. the block layer). - For more information see http://www.torque.net/sg/sg_io.html - - The older, version 2 documents discuss the original sg interface in detail: - http://www.torque.net/sg/p/scsi-generic.txt - http://www.torque.net/sg/p/scsi-generic_long.txt - Also available: <kernel_source>/Documentation/scsi/scsi-generic.txt - - Utility and test programs are available at the sg web site.
