Description Dave Airlie 2010-01-07 15:43:38 UTC

currently plymouth just uses card0 or fb0 as the primary display device,
however in a multi-card system, the boot vga device may not be the first VGA device enumerated on the bus.

there is a sysfs attribute to denote which PCI device is the boot VGA device,
/sys/class/graphics/fb0/device/boot_vga

/sys/class/drm/card0/device/boot_vga

reading that file with a 1 should give you the device that is the console.

There is a bug on 64-bit x86 where fbcon would pick the a different answer to 32-bit this has been sent as patch to lkml and I'll put it into Fedora.

In my use case, I have a problematic BIOS/kernel module that needs to be initialized in a certain order which reverses the relationship so I'd still like to have the option to choose where I throw up the splash screen.  I'm doing an embedded kiosk setup, so I'll probably just recompile with my settings hard-coded; but having config knobs to turn would be really nice :)

I pushed some fixes for this here:

Now we draw the splash on all drm devices.
