The following reply was made to PR kern/163812; it has been noted by GNATS. From: dfilter@FreeBSD.ORG (dfilter service) To: bug-followup@FreeBSD.org Cc: Subject: Re: kern/163812: commit references a PR Date: Tue, 14 Feb 2012 00:18:50 +0000 (UTC) Author: marius Date: Tue Feb 14 00:18:35 2012 New Revision: 231621 URL: http://svn.freebsd.org/changeset/base/231621 Log: - As it turns out, MSI-X is broken for at least LSI SAS1068E when passed through by VMware so blacklist their PCI-PCI bridge for MSI/MSI-X here. Note that besides currently there not being a quirk type that disables MSI-X only and there's no evidence that MSI doesn't work with the VMware pass-through, it's really questionable whether MSI generally works in that setup as VMware only mention three know working devices [1, p. 4]. Also not that this quirk entry currently doesn't affect the devices emulated by VMware in any way as these don't claim support MSI/MSI-X to begin with. [2] While at it, make the PCI quirk table const and static. - Remove some duplicated empty lines. - Use DEVMETHOD_END.
