1856951 - Wayland Firefox - fixing 'More than 1 GPU from same vendor, cannot deduce device'

Status: UNCONFIRMED

(Core :: Widget: Gtk, defect)

Description

[willrabbermann]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/115.0

Steps to reproduce:

Start firefox in a wayland compositor (KDE Plasma, kwin_wayland)

Actual results:

"
will@gentoo ~ λ firefox
will@gentoo ~ λ Crash Annotation GraphicsCriticalError: |[0][GFX1-]: More than 1 GPU from same vendor detected via PCI, cannot deduce device
(t=0.263901) [GFX1-]: More than 1 GPU from same vendor detected via PCI, cannot deduce device

"

Expected results:

Instead of this behavior, firefox should first find each VGA sys bus device ID, (in my case 0000:08:00.0 (nvidia 1660 ti) and 0000:01:00.0 (nvidia 3060 xc) and check in /sys/bus/pci/devices/0000:$ID/ for a file called boot_vga. If boot_vga exists and contains '1', that VGA ID target can be considered the primary display output device. I am using two GPU's in this case for a virtual machine and host display. the 3060 xc has a vfio_pci driver manually overriden during the initramfs setup so I can pass it in to a VM and isn't initialized by the nvidia drivers. The 1660 ti has the nvidia driver initialized as it is my host display device.

Here is some additional system info using a motd utility I wrote that queries some /sys/bus/pci/devices/$ID/ info automatically.

As far as I can tell this problem only occurs in Wayland firefox. Xorg firefox allows me to use two GPU's no problem.

Can you run Firefox with MOZ_GFX_DEBUG=1 env variable and attach the log here?
Thanks.

Comment 2

[Martin Stránský [:stransky] (ni? me)]

Also do I understand correctly that Firefox crashes and doesn't start in Wayland mode?

Yes.

Can you get firefox backtrace? From coredumpctl for instance?

Thanks.

Attachment: Firefox crash strace

I ran strace firefox &> firefox_strace
If this isn't ok, let me know ill give you a different trace.

Comment 6

[Martin Stránský [:stransky] (ni? me)]

Thanks but I'd need stack trace from crash. strace prints kernel calls but doen't provide info about crash. See

Thanks.
