What is a "prime system"? I'm a little surprised that users would really care about the message. But I do see comments like these:

This reverts commit b516ea586d717472178e6ef1c152e85608b0ce32. While this fixes audio for a number of users, this commit has the sideaffect of breaking the BIOS workaround that's required to make the GPU on the nvidia P50 work, by causing the GPU's PCI device function to stop working after it's been set to multifunction mode. Signed-off-by: Lyude Paul <lyude at redhat.com>

Since quirk_nvidia_hda() was added there's now two nvidia device functions on any laptops with nvidia GPUs: the HDA controller, and the GPU itself. Unfortunately this has the sideaffect of breaking quirk_reset_lenovo_thinkpad_50_nvgpu() since pci_reset_function() was using pci_parent_bus_reset() to reset the GPU's respective PCI bus, and pci_parent_bus_reset() does not work on busses which

From: Lukas Wunner <lukas at wunner.de> The integrated HDA controller on Nvidia GPUs can be hidden with a bit in the GPU's config space. Information about this scheme was provided by NVIDIA on their forums. Many laptops now ship with this device hidden, meaning that Linux users of affected platforms (where the HDMI connector comes off the NVIDIA GPU) cannot use HDMI audio

This is missing a reference to the commit

Przemysław Kopa reports that since commit b516ea586d71 ("PCI: Enable NVIDIA HDA controllers"), the discrete GPU Nvidia GeForce GT 540M on his 2011 Samsung laptop refuses to runtime suspend, resulting in a power regression and excessive heat. Rivera Valdez witnesses the same issue with a GeForce GT 525M (GF108M) of the same era, as does another Arch Linux user named "R0AR" with

Add a topology description to the virtio-iommu driver and enable x86 platforms. Since [v2] we have made some progress on adding ACPI support for virtio-iommu, which is the preferred boot method on x86. It will be a new vendor-agnostic table describing para-virtual topologies in a minimal format. However some platforms don't use either ACPI or DT for booting (for example microvm), and will

On over 40 Intel-based Asus products, the nvidia GPU becomes unusable after S3 suspend/resume. The affected products include multiple generations of nvidia GPUs and Intel SoCs. After resume, nouveau logs many errors such as: fifo: fault 00 [READ] at 0000005555555000 engine 00 [GR] client 04 [HUB/FE] reason 4a [] on channel -1 [007fa91000 unknown] DRM: failed to idle channel 0 [DRM]
