mesa using softpipe, X using nouveau

terrenana

Hi,

I have a problem with mesa. Mesa is using softpipe software rendering instead of nouveau. VIDEO_CARDS is set to nouveau, X server is using nouveau correctly. I have frankly no clue why mesa refuses to just use the nouveau driver.

Please review and share the log file at either ~/.local/share/xorg/Xorg.0.log or /var/log/Xorg.0.log (with a recent timestamp) as that will show why.

Xorg.0.log.

Nouveau appears to be loading correctly. The only thing on my system (to my knowledge) that is using software rendering is Mesa.

dmesg: https://pastebin.com/4dQmF0Ey

Even with DRM_NOUVEAU built as a module nothing changes. dmesg and Xorg log output unchanged. Is there a way for me to see a mesa log? I think the problem is with mesa.

Ah. So the problem is nouveau is missing some component of acceleration. How would I rectify this?

Fix the 4 missing firmware files that dmesg is complaining about and it is likely that everything else will just work.

Edit: if nouveau is now a module, the loading timestamp will change to much later in the boot sequence and should not show the 4 missing firmwares.

I believe the problem is I dont have nvidia-firmware installed properly. in the kernel param CONIFG_FW_LOADER, i have /lib/firmware. Inside /lib/firmware there is a folder called nouveau, where nvidia-firmware package installed its files. When I attempt to change CONFIG_FW_LOADER, it also changes CONFIG_EXTRA_FIRMWARE. when I build the kernel, it then errors. showing this

If you wish to want to use CONFIG_EXTRA_FIRMWARE, you must list FILES not directories relative to CONFIG_EXTRA_FIRMWARE_DIR (which defaults to /lib/firmware).

For example, using what already is shown in the output, CONFIG_EXTRA_FIRMWARE="nvidia/gp106/nvdec/scrubber.bin nvidia/gp106/acr/bl.bin"

But 4 unknown files are also necessary.

This is usually not necessary if DRM_NOUVEAU is loaded as a module as it can read from the file system.

Even when built as a module it wasnt working. How do I get the module to load when needed?

Please show the dmesg output when built as a module

Even if built as module, glxinfo -B still shows mesa as not using nouveau

So how do I get dracut to load it? There aren't files to add to build into the kernel matching those names. Can I just add them all? (and how)

terrenana,

I roll my initramfs by hand. I don't know how dracut (or genkernel) work.

The kernel needs all the bits to be accessible when the code is initialised.
Everything built into the kernel binary, everything in the initrd or everything on the root filesystem work.

I think it would be easist to just build the needed firmware into the kernel. How can i specify that I want the contents of /lib/firmware built into the kernel?

I found all the directories of the missing firmware. its a bit weird though because each one exists in basically every subdir of nvidia, and in each there are 4 files, I would have to manually include hundreds of files. There is no way that is what was intended?

Right. I should have realized that. Well I guess I'll just include all 4 files each time

PROGRESS!!!!!! ok so now mesa is using nouveau, although dmesg still says that it cant load pmu firmware. But hey, mesa works, so I'm not gonna worry about it. Thank both of you SO much for your help and patience. I really appreciate it.
