The programming guide presents copied structure layouts, callbacks and management paths as current interfaces. API and build changes have left those copies describing fields and operations that no longer exist. Commit08e532715d("Remove procfs support") removed the documented procfs callbacks and paths. Commit2090b6811a("qla2x00t: remove detect() callback") moved QLogic setup out of the template detect hook. Make scst/include/scst.h and scst/SysfsRules authoritative, and label embedded declarations as historical outlines. Update callback names, QLogic initialization, sysfs trace commands and build modes. The supported kernels in nightly/conf/nightly.conf also span different Kconfig and logging interfaces. Refer readers to the exact target kernel instead of prescribing fixed debug symbols, buffer limits and syslog paths.
Overview
This is the source code repository of the SCST project. SCST is a collection of Linux kernel drivers that implement SCSI target functionality. The SCST project includes:
- The SCST core in the scst/ subdirectory.
- A tool for loading, saving and modifying the SCST configuration in directory scstadmin/.
- Several SCSI target drivers in the directories iscsi-scst/, qla2x00t-32gbit/, qla2x00t/, srpt/, scst_local/ and fcst/.
- User space programs in the usr/ subdirectory, e.g. fileio_tgt.
- Various documentation in the doc/ subdirectory.
Instructions for building and installing SCST are available in the INSTALL.md file.
QLogic target driver
Two QLogic target drivers are included in the SCST project.
The default driver is located in the qla2x00t-32gbit directory. It is the newer one.
May anyone wish to switch back to the older driver that only supported up to
16 Gb/s adapters, it is located in qla2x00t directory. To make use of the
older driver build scst with environment variable QLA_32GBIT=no set.
