Subject: Re: [PATCH 1/3] x86/quirks: Scan all busses for early PCI quirks
Date: Mon, 14 Dec 2020 15:32:35 -0300 [thread overview]
Message-ID: <CAHD1Q_zKmQawrOQrR3DM0nnBF06nO=L_PcMEQMBvZA6xKMxtWw@mail.gmail.com> (raw)
In-Reply-To: <20201130202021.GA1106292@bjorn-Precision-5520>
Thank you for the clarification Bjorn! I was on vacation..sorry for my delay.
Closing the loop here, I understand we're not getting this patch
merged (due to its restriction to domain 0) and there was a suggestion
in the thread of trying to block MSIs from the IOMMU init code (which
also have the restriction of only working in iommu-enabled systems).
Hope the thread is helpful and if somebody faces this issue, can
comment here and at least find this approach, maybe test the patch.
Thanks to all involved!
