The driver source has been Announced a couple of times, the last version on 12/18/2018. The driver has been hosted on gitlab for review has had contributions from the community. gitlab (git@gitlab.com:jsmart/efct-Emulex_FC_Target.git) The driver integrates into the source tree at the (new) drivers/scsi/elx subdirectory. The driver consists of the following components: - A libefc_sli subdirectory: This subdirectory contains a library that encapsulates common definitions and routines for an Emulex SLI-4 adapter. - A libefc subdirectory: This subdirectory contains a library of common routines. Of major import is a number of routines that implement a FC Discovery engine for target mode. - An efct subdirectory: This subdirectory contains the efct target mode device driver. The driver utilizes the above librarys and plugs into the SCSI LIO interfaces. The driver is SCSI only at this time. The patches populate the libraries and device driver and can only be compiled as a complete set. This driver is completely independent from the lpfc device driver and there is no overlap on PCI ID's. The patches have been cut against the 5.6/scsi-queue branch. Thank you to those that have contributed to the driver in the past. Review comments welcome! -- james V2 modifications: Contains the following modifications based on prior review comments: Indentation/Alignment/Spacing changes Comments: format cleanup; removed obvious or unnecessary comments; Added comments for clarity. Headers use #ifndef comparing for prior inclusion Cleanup structure names (remove _s suffix) Encapsulate use of macro arguments Refactor to remove static function declarations for static local routines Removed unused variables Fix SLI4_INTF_VALID_MASK for 32bits Ensure no BIT() use Use __ffs() in page count macro Reorg to move field defines out of structure definition Commonize command building routines to reduce duplication LIO interface: Removed scsi initiator includes Cleaned up interface defines Removed lio WWN version attribute. Expanded macros within logging macros Cleaned up lio state setting macro Remove __force use Modularized session debugfs code so can be easily replaced. Cleaned up abort task handling. Return after initiating. Modularized where possible to reduce duplication Convert from kthread to workqueue use Remove unused macros Add missing TARGET_CORE build attribute Fix kbuild test robot warnings Comments not addressed: Use of __packed: not believed necessary Session debugfs code remains. There is not yet a common lio mechanism to replace with.
