dmesg with nouveau.debug=trace + acpidump + xorg.conf

I've got a portable computer with an Intel graphic card and a nvidia discrete card (G 105M).
I've installed Fedora 26.
Everything should run fine with nouveau and Prime.

However, xrandr --listproviders only send me 1 provider, which is the Intel card.

I've seen a problem with the BIOS and the nvidia card :

[ 2.777871] nouveau 0000:01:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0x0000
[ 2.777887] nouveau 0000:01:00.0: bios: unable to locate usable image
[ 2.777895] nouveau 0000:01:00.0: bios ctor failed, -22
