Linux Driver for Emulex LightPulse Fibre Channel HBAs

Summary

This device driver provides the sources for Emulex's LPFC (LightPulse Fibre Channel) family of HBAs. The source base is developed and tested specifically for the 2.6 Linux kernel. This driver is derived from Emulex's currently shipping driver which supports several application and storage providers.

Intentions

Emulex will be working with the open source community with the intention of achieving acceptance of this source into the upstream kernel.

Emulex will also continue to work with application and storage provider partners, many of whom are active members of the open source community, to evolve the code base to meet both upstream kernel and continuing business needs.

Planned Modifications

Common Unix OS abstractions will be removed. Replace the current abstractions that support multiple UNIX Operating systems with a Linux-specific implementation.
All 2.4 Kernel-specific functionality will be removed.
Emulex is working on a compatibility file to account for various kernel support requirements and to minimize ifdefs.
Investigate migrating the internal driver queuing to the Linux SCSI stack design for command queuing.
Rework the driver's data structure typing to eliminate typecasting as much as possible in the source.
Support other 2.6 Kernel features going forward such as:
- Enable target probing from the driver
- PCI probing changes/hotplug
- Use mempool API
- wait_queue changes
- Investigate use of completion events
- Investigate use of tasklets or work queues for slow path (e.g. discovery)
