The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. 2017-07-03T15:56:45Z Alexander Motin mav@FreeBSD.org 2017-07-03T15:56:45Z urn:sha1:a94fab67bb9c07d5837c9e2ad25d48b9b701643a Instead of using GID_FT SNS request to get list of registered FCP ports, use GID_PT to get list of all Nx_Ports, and then use GFF_ID and/or GFT_ID requests to find whether they are FCP and target capable. The problem with old approach is that GID_FT does not report ports without FC-4 type registered. In particular it was impossible to boot OS from FreeBSD FC target using QLogic FC BIOS, since one does not register FC-4 type even on new cards and so ignored by old code as incompatible. As a side bonus this allows initiator to skip pointless logins to other initiators by fetching that information from SNS instead. In case some switches do not implement GFF_ID/GFT_ID correctly, add sysctls to disable that functionality. I handled broken GFF_ID of my Brocade 200E, but there may be other switches with different bugs. Linux also uses GID_PT, but GFF_ID is disabled by default there, and GFT_ID is not supported.

Also it removes DMA resources allocation for hardcoded number of requests before fetching the real number from firmware. Also it prepares ground for more flexible IRQs allocation according to firmware capabilities.

It would be good to use target name from CTL here instead of hostname, but it is not passed here through CAM now.

At this point this unification just slightly reduces memory usage, but as next step I plan to reuse shared handle space for other IOCB types. 2015-12-25T03:44:29Z Alexander Motin mav@FreeBSD.org 2015-12-25T03:44:29Z urn:sha1:a4f43c01c0719339ac6b348c93a061f35d47e096 Previously it was done only on full chip reinit, that caused old ports resurrect in case of virtual port reenabling. 2015-11-23T10:06:19Z Alexander Motin mav@FreeBSD.org 2015-11-23T10:06:19Z urn:sha1:3e6deb330e6613bcd7b3ec227add1eb2a2dcaaf8 Hacks to enable target mode there complicated code, while didn't really work. And for outdated hardware fixing it is not really interesting. Initiator mode tested with Qlogic 1080 adapter is still working fine. 2015-11-19T17:43:47Z Alexander Motin mav@FreeBSD.org 2015-11-19T17:43:47Z urn:sha1:eea52482f90e7c5da565833abbbc7a544a054d07 This change simplifies and unifies port adding/updating for loop and fabric scanners. It also fixes problems with scanning restarts due to concurrent port databases changes. It also fixes many cosmetic issues.
