SCST is a collection of Linux kernel drivers that implement SCSI target functionality. The SCST project includes: 1. The SCST core in the scst/ subdirectory. 2. A tool for loading, saving and modifying the SCST configuration in directory scstadmin/. 3. Several SCSI target drivers in the directories iscsi-scst/, qla2x00t-32gbit/, qla2x00t/, srpt/, scst_local/ and fcst/. 4. User space programs in the usr/ subdirectory, e.g. fileio_tgt. 5. Various documentation in the doc/ subdirectory. ## Documentation - [Building and installing SCST](INSTALL.md). - Build options: [Clang](README.clang), [cross-compilation](README.cross-compilation), and [kernel module signing](README.module-signing). - [Configuration and administration](scstadmin/README): targets, devices, LUNs, and `/etc/scst.conf`. - [Core and device handlers](scst/README): operating modes, module parameters, and sysfs configuration. - Target drivers: [iSCSI](iscsi-scst/README), [iSER](iscsi-scst/README.iser), [QLogic Fibre Channel](qla2x00t-32gbit/qla2x00-target/README), [SRP](srpt/README), [FCoE](fcst/README), and [local loopback](scst_local/README). - [Performance tuning](README.performance). - [Clustered persistent reservations](scst/README.dlm): synchronization through DLM. - [T10 protection information](scst/T10-PI): data integrity modes and configuration. - Developer references: [architecture](doc/scst_pg.sgml) and [userspace handler interface](doc/scst_user_spec.sgml) (SGML sources), and [sysfs interface rules](scst/SysfsRules). - [Contributing](CONTRIBUTING.md): code style, commit conventions, local checks, and guides to KUnit and component testing. ## Current master packages Prebuilt x86_64 packages from the latest successfully published `master` build are available in the rolling [`master-rpm` prerelease](https://github.com/SCST-project/scst/releases/tag/master-rpm). These are development snapshots, not SCST releases. The snapshot contains RPM bundles for selected Rocky Linux and Oracle Linux UEK kernels. It also contains Ubuntu LTS bundles with `scst-dkms`, `scstadmin` and `iscsi-scst` binary packages and their Debian source package files. Exact distribution releases and RPM kernel versions are included in the asset names. Every `.tar.gz` bundle has a matching `.sha256` file. The complete snapshot is replaced after each successful package workflow for the current `master` commit. ## 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. Vladislav Bolkhovitin , http://scst.sourceforge.net ## Sourceforge achievements
