From 35ee0dc20abac1f6f4050bebf66979f24e1ce316 Mon Sep 17 00:00:00 2001 From: patrick Date: Fri, 5 Jul 2024 22:53:57 +0000 Subject: [PATCH] When trying to enable multiple MSI vectors, check the flag first whether or not it's supported. This allows qwx(4) to properly handle missing support for that and switch back to a single MSI vector. ok kettenis@ --- sys/arch/arm64/dev/pci_machdep.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/sys/arch/arm64/dev/pci_machdep.c b/sys/arch/arm64/dev/pci_machdep.c index 86b8edd679f..fbfb07e56d4 100644 --- a/sys/arch/arm64/dev/pci_machdep.c +++ b/sys/arch/arm64/dev/pci_machdep.c @@ -1,4 +1,4 @@ -/* $OpenBSD: pci_machdep.c,v 1.6 2024/02/03 10:37:25 kettenis Exp $ */ +/* $OpenBSD: pci_machdep.c,v 1.7 2024/07/05 22:53:57 patrick Exp $ */ /* * Copyright (c) 2019 Mark Kettenis @@ -32,7 +32,7 @@ pci_intr_enable_msivec(struct pci_attach_args *pa, int num_vec) pcireg_t reg; int mmc, mme, off; - if ((pa->pa_flags & PCI_FLAGS_MSI_ENABLED) == 0 || + if ((pa->pa_flags & PCI_FLAGS_MSIVEC_ENABLED) == 0 || pci_get_capability(pc, tag, PCI_CAP_MSI, &off, ®) == 0) return 1; -- 2.20.1
