I'm still using the exact same kernel that I was before the upgrade (4.4.6), and I've got the firmware in /lib/firmware/vbios.rom with the following module options set in /etc/modprobe/nouveau.conf: options nouveau config=NvBios=vbios.rom,NvForcePost=1 debug=VBIOS=debug When nouveau loads in pure EFI mode, it logs the following: [ 1.948618] fb: switching to nouveaufb from EFI VGA [ 1.953188] nouveau 0000:01:00.0: enabling device (0002 -> 0003) [ 1.953230] nouveau 0000:01:00.0: NVIDIA G84 (084700a2) [ 1.953353] nouveau 0000:01:00.0: Direct firmware load for vbios.rom failed with error -2 [ 1.953362] nouveau 0000:01:00.0: Falling back to user helper [ 61.952174] nouveau 0000:01:00.0: bios: vbios.rom invalid [ 61.953062] nouveau 0000:01:00.0: Invalid ROM contents [ 61.953079] nouveau 0000:01:00.0: bios: unable to locate usable image [ 61.953087] nouveau 0000:01:00.0: bios ctor failed, -22 [ 61.953097] nouveau: probe of 0000:01:00.0 failed with error -22 When nouveau loads in BIOS emulation mode, it logs the following: [ 1.797074] nouveau 0000:01:00.0: NVIDIA G84 (084700a2) [ 1.797257] nouveau 0000:01:00.0: Direct firmware load for vbios.rom failed with error -2 [ 1.797342] nouveau 0000:01:00.0: Falling back to user helper [ 61.796123] nouveau 0000:01:00.0: bios: vbios.rom invalid [ 61.813299] nouveau 0000:01:00.0: bios: version 60.84.49.03.00 [ 61.875766] nouveau 0000:01:00.0: fb: 128 MiB GDDR3 [ 61.926834] nouveau 0000:01:00.0: DRM: VRAM: 128 MiB [ 61.926922] nouveau 0000:01:00.0: DRM: GART: 1048576 MiB [ 61.927012] nouveau 0000:01:00.0: DRM: TMDS table version 2.0 [ 61.927101] nouveau 0000:01:00.0: DRM: DCB version 4.0 [ 61.927189] nouveau 0000:01:00.0: DRM: DCB outp 00: 01000123 00010034 [ 61.927279] nouveau 0000:01:00.0: DRM: DCB outp 01: 02011210 00000028 [ 61.927369] nouveau 0000:01:00.0: DRM: DCB outp 02: 02011212 00010030 [ 61.927459] nouveau 0000:01:00.0: DRM: DCB outp 03: 01011211 0080c070 [ 61.927547] nouveau 0000:01:00.0: DRM: DCB conn 00: 0040 [ 61.927636] nouveau 0000:01:00.0: DRM: DCB conn 01: 1120 [ 61.936343] nouveau 0000:01:00.0: DRM: unknown connector type 20 [ 61.936495] nouveau 0000:01:00.0: DRM: failed to create encoder 0/1/0: -19 [ 61.953987] nouveau 0000:01:00.0: DRM: MM: using CRYPT for buffer copies [ 62.001097] nouveau 0000:01:00.0: DRM: allocated 1440x900 fb: 0x50000, bo ffff880036c5a800 [ 62.001309] fbcon: nouveaufb (fb0) is primary device [ 62.091280] nouveau 0000:01:00.0: fb0: nouveaufb frame buffer device [ 62.096133] [drm] Initialized nouveau 1.3.1 20120801 for 0000:01:00.0 on minor 0 As you can see, the loading of /lib/firmware/vbios.rom fails with ENOENT, but it's certainly there. I verified that /lib/firmware/vbios.rom is exactly the same as /sys/kernel/debug/dri/0/vbios.rom in BIOS-emulation mode. Odd... gonna have to dig into it a bit more later, but if you have any ideas, I'd appreciate them.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
