Subject: [PATCH 11/13] PCI: Make pci_host_common_probe() declare its reliance on MSI domains
Date: Thu, 25 Feb 2021 15:10:21 +0000 [thread overview]
Message-ID: <20210225151023.3642391-12-maz@kernel.org> (raw)
In-Reply-To: <20210225151023.3642391-1-maz@kernel.org>
The generic PCI host driver relies on MSI domains for MSIs to
be provided to its end-points. Make this dependency explicit.
This cures the warnings occuring on arm/arm64 VMs when booted
with PCI virtio devices and no MSI controller (no GICv3 ITS,
for example).
It is likely that other drivers will need to express the same
dependency.
