Subject: [PATCH 5.15 17/20] PCI: Add MSI masking quirk for Nvidia ION AHCI
Date: Fri, 19 Nov 2021 18:39:35 +0100 [thread overview]
Message-ID: <20211119171445.211976547@linuxfoundation.org> (raw)
In-Reply-To: <20211119171444.640508836@linuxfoundation.org>
From: Marc Zyngier <maz@kernel.org>
commit f21082fb20dbfb3e42b769b59ef21c2a7f2c7c1f upstream.
The ION AHCI device pretends that MSI masking isn't a thing, while it
actually implements it and needs MSIs to be unmasked to work. Add a quirk
to that effect.
