https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D257273 Bug ID: 257273 Summary: PCI-e passthrough MSI-X not working for iwlwifi Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bhyve Assignee: virtualization@FreeBSD.org Reporter: bz@FreeBSD.org Hi, opening the PR to track this. When running FreeBSD inside bhyve to test/use iwlwifi wireless (https://wiki.freebsd.org/WiFi/Iwlwifi) this does not work with the default driver using MSI-X. It seems interrupts are not arriving. When disabling MSI-X (by patch for tunable) and forcing it to use MSI that does work. In addition to some tracing done as suggested by @grehan I also tried/appli= ed D20623, D24549, and D28277 locally (one which removed some noise from traci= ng) but apart from that did not make any difference. In case anyone has seen similar or has ideas what to try, please let me kno= w. --=20 You are receiving this mail because: You are the assignee for the bug.=
