src/sys/dev/isp/isp_pci.c, branch releng/12.2 FreeBSD source tree MFC r344661, r344669: Limit 24xx adapters to only MSI interrupts by default. 2019-03-08T00:56:07+00:00 Alexander Motin mav@FreeBSD.org 2019-03-08T00:56:07+00:00 4a611c712882ac9ab5d07c594aa82f2561e5bcaf This was actually the known good configuration we used before. Single MSI-X configuration doesn't even work there on my tests, just due to lack of documentation not sure whether by design or I am doing something wrong.

MFC r344660: Add to isp(4) tunables to limit MSI/MSI-X usage. 2019-03-08T00:54:34+00:00 Alexander Motin mav@FreeBSD.org 2019-03-08T00:54:34+00:00 83d9b5559bedab547d7b05cc2f194283bdb47dc7 There are some problem reports possibly related to the new driver use of multiple interrupts on older cards. Hopefully this allow to workaround them.

sys/dev: further adoption of SPDX licensing ID tags. 2017-11-27T14:52:40+00:00 Pedro F. Giffuni pfg@FreeBSD.org 2017-11-27T14:52:40+00:00 718cf2ccb9956613756ab15d7a0e28f2c8e91cab Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. 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.

Add initial support for multiple MSI-X vectors. 2017-03-19T19:11:40+00:00 Alexander Motin mav@FreeBSD.org 2017-03-19T19:11:40+00:00 08826086fe2c291dc322f6f3e50ee2826511e5b4 For 24xx and above use 2 vectors (default and response queue). For 26xx and above use 3 vectors (default, response and ATIO queues). Due to global lock interrupt hardlers never run simultaneously now, but at least this allows to save one regitster read per interrupt. MFC after: 2 weeks
