Subject: Re: [PATCH v4] pci: prevent putting nvidia GPUs into lower device states on certain intel bridges
Date: Mon, 9 Dec 2019 12:17:10 +0100 [thread overview]
Message-ID: <CACO55tu+hT1WGbBn_nxLR=A-X6YWmeuz-UztJKw0QAFQDDV_xg@mail.gmail.com> (raw)
In-Reply-To: <e7aec10d789b322ca98f4b250923b0f14f2b8226.camel@redhat.com>
anybody any other ideas? It seems that both patches don't really fix
the issue and I have no idea left on my side to try out. The only
thing left I could do to further investigate would be to reverse
engineer the Nvidia driver as they support runpm on Turing+ GPUs now,
but I've heard users having similar issues to the one Lyude told us
about... and I couldn't verify that the patches help there either in a
reliable way.
