 Posted: Sun Jul 15, 2018 7:00 pm Post subject: Trouble enabling amdgpu on new install |
 |
|
| I recently installed Gentoo and I already downloaded the xorg amdgpu drivers and I'm having trouble enabling them. In my /etc/portage/make.conf I have VIDEO_CARDS="amdgpu radeonsi" (I have an RX 480). But when I run emerge --ask --changed-use @world then I get a message saying it couldn't find a video_cards setting so it sets it to the default. When I reboot it doesn't load the drivers. I am probably forgetting something or doing something wrong as I am new to Gentoo. Thank you |

I just got one of these working last weekend so perhaps I can offer some assistance.
First i'll start by offering this post as some reference and things to consider.
https://forums.gentoo.org/viewtopic-p-8240822.html#8240822
The important things to take note of with the post above is my gpu's would not function properly until i emerged linux-firmware, compiled amdgpu into the kernel binary and made certain to include the correct amdgpu firmware into the kernel image.
Now on to a couple questions
Which portage profile are you using? Did you switch to a "desktop" portage profile? you really should do this if your considering using a DE or WM
Did you complete a full emerge xorg-x11? If you haven't emerged the xorg-x11 meta package your install may be missing several xorg packages required for xorg to function properly.
Did you install the linux-firmware package? If linux-firmware is missing your GPU definitely will not function.
Can you paste your make.conf to https://bpaste.net and reply with the bpaste link? we can compare notes 
If you dont know how to do this you can
| Code: | | emerge wgetpaste && wgetpaste -s bpaste /etc/portage/make.conf |
My system is running systemd with kde plasma installed and it's uefi booted.
This system's sole existence is to function as a GPU crypto miner pc so the local desktop never gets used. If i ever do use kde plasma it's via x2go remote desktop.
Despite this the same setup required to make this functional should apply to your system as well. Check the below system config for reference tips.
Notes here - this system is only a hyperthreaded dual core 6th generation pentium and uses distcc against a 20 core xeon server to make life a little easier so the cflags are configured cpu specific.
Here's my kernel config from gentoo-sources 4.17

Your make.conf file is basic but there's nothing incorrect about it. the problem your experiencing must be from another contributing issue such as perhaps your kernel config. did you compile your own Linux kernel or use genkernel?
You may need to if you haven't configure and compile your own kernel config to ensure the amdgpu driver and firmware are included in the kernel image
There's little information you've provided so far to go on for reference other than guessing based on common issues many people may experience.
If you do have the video_cards configured in make.conf that config should be used by portage when building xorg relevant packages. Why it's not is curious.
The xorg drivers alone are not enough to make a graphics card function however. You must also have the correct Linux kernel configuration.
Even if the default video_cards setting in make.conf was set to defaults or undefined that would not prevent the rest of a correctly configured Gentoo system with a graphics card matching a default type setting from functioning.

I can confirm your make.conf file has no config errors.
I tested my system utilizing both setups to try and get opencl compute to work last weekend by compiling amdgpu kernel driver into the kernel image including firmware and as module then tried to load gpu firmware from userland and it did not work. loading a module and firmware from userland should have worked but it did not.
Based on many years of using Linux and Gentoo having drivers or software load on demand is ideal but it does not always work out as well as you hoped it could under some unusual circumstances. Sometimes the entire opposite is true where using a kernel module is more ideal such as configuring the linux kernel for alsa sound.
Compiling the amdgpu driver into my kernel image and including the firmware in this circumstance fixed the issues with the gpu entirely.
Try it and see if it helps. One other thing i can offer is while Genkernel is a beneficial and useful tool to aid with building a functional kernel you should never assume the default configuration genkernel offers will be correct or adequate for your specific system.
Genkernel is and always has been at best a good starting guide and additional kernel config customization is more often than not beneficial or necessary.
Learning many of these things just takes time or testing what works for your hardware or use case.

| Ok I'll give it a shot. Does this mean I have to install Gentoo again? Or I just make a new kernel config and load it? |

One of the great things with gentoo is if you already have a functional install you should never need to start from scratch unless something is very broken or you let your install go so far out of date that updating would be more difficult than reinstalling from scratch. In your situation there should be nothing seriously broken enough to need a full reinstall.
Just adjust your kernel config and recompile then test your results after a reboot. just be certain to update your bootloader config before rebooting so the new kernel is available and your functional backup if the new kernel config doesn't boot for whatever reasons that can happen.

| Ok. How do I edit the kernel configuration? Can I edit it with menuconfig? |

I've not personally used genkernel in eons but i am fairly certain there is an option flag you can use with genkernel to trigger menuconfig to load. You could as well absolutely just configure your own kernel config with gentoo sources using the "manual" native Linux kernel methods. The Linux kernel itself requires no third party tools to configure and build a kernel.
I made a youtube video some time ago that details the required steps to configure and build a Linux kernel with Gentoo that may be useful reference

owen.geer,
Pass genkernel the --menuconfig option ... it might just be one '-'
may be useful.

| So I used genkernel --menuconfig and when I try to enable the kernel settings on https://wiki.gentoo.org/wiki/AMDGPU some of them aren't there. Some are, some aren't. I looked everywhere and tried everything but some of the options aren't there. I compiled it anyway and amdgpu still doesn't work. Do I have to do a non genkernel compile for these options to show up? Thanks |

owen.geer,
What kernel are you using?
AMDGPU changed a lot at kernel 4.15.0
menuconfig hides options that have unsatisfied dependencies. It removes clutter.
In menuconfig, press 'z' to turn on the display of hidden options.
Now the search will find them and you can read the Depends On: for the hidden option you need.
The Depends on must evaluate to true before the option can be selected.

If you are experiencing challenges or difficulties you could use the kernel config from my amdgpu based system as a template. Once you know how to backup your kernel config and replace that config file in a kernel source directory anyone can use anyone else's linux kernel config as a functional example and make any desired or necessary changes.
The linux kernel config file relevant to any linux kernel source directory is always located at
| Code: | | /usr/src/linux-<version>/.config |
Backing up that file to
| Code: | | /usr/src/config-<version> |
can effectively create a config backup relevant to that kernel source version.
Here's the kernel config for gentoo-sources 4.17.x from my amdgpu based system. This pc runs an intel z270-a asus motherboard and 6th generation pentium cpu so perhaps any necessary changes may be minimal.

Try using a 4.17 version of the kernel.
In your mahe.conf file change VIDEO_CARDS="amdgpu radeonsi radeon" to VIDEO_CARDS="amdgpu radeonsi"
If xf86-video-ati is installed remove it.
You may need to add x11-libs/libdrm video_cards_radeon to package.use |

In the kernel some settings are dependent.
Searching the config with / key you can usually type in the config name.
This will usually bring up the location in the kernel menu and what triggers it to appear or hide. |

| How do I install the newer kernel? (4.17). I tried using emerge gentoo-sources but it just installs 4.14. |

owen.geer,
You keyword it to tell portage that this testing package is permitted.

owen.geer just be certain to use the package.accept_keywords method for keywording the kernel sources. You really should avoid keyword accepting every testing package in the portage tree by not using
| Code: | | ACCEPT_KEYWORDS="~amd64" |
in make.conf
If you were feeling challenged already keyword accepting every testing package surely will make thing much more challenging
Here's the contents of the package.accept_keywords file from my amdgpu miner.
| Code: | vargur ~ # cat /etc/portage/package.accept_keywords
sys-kernel/gentoo-sources
sys-kernel/linux-firmware
# opencl
dev-libs/amdgpu-pro-opencl
dev-util/clinfo
# x2go
net-misc/x2goserver
net-misc/nx |

| So do I remove ACCPET_KEYWORDS="~amd64" from my make.conf or keep it? I already installed the new kernel, but it only installed 4.17.5. Is there any way I can install 4.17.8? |

| Code: | | ACCEPT_KEYWORDS="~amd64" |
will unmask every testing package in the portage tree. This could be unwise for several reasons one of the most significant being that this could also upgrade glibc and the compiler toolchain to unstable testing versions. glibc when upgraded cannot be safely or easily downgraded without many packages breaking due to missing c library symbols that likely would not be available in an older more stable version of glibc.
Managing a fully unmasked gentoo install can be very challenging even for experienced users. Just use stable default portage keywording and unmask unstable or testing packages on a per package as needed basis.
I believe this is the default portage keywording for amd64 gentoo
| Code: | | ACCEPT_KEYWORDS="amd64" |
https://packages.gentoo.org/packages/sys-kernel/gentoo-sources
It appears that 4.17.8 is in the portage tree and the ebuild was added today. you may need to emerge --sync to make the new ebuild version available on your system.

which console text editor are you using? If your using vim i find that can overcomplicate matters when all you want to do is create or edit a simple text document with a console terminal. Nano works best for this
You also must create and edit that file as the root user

Hey, sorry for asking so many questions. I'm new to gentoo and I'm not finding very useful information for some things on the wiki and internet.
Do you know how I can use your kernel configuration, while I'm in CLI mode? I can't access the internet except using lynks, is there a way I can copy it from there? |

This should get you a local copy of the kernel config from my bpaste.
| Code: | | wget https://bpaste.net/raw/c55adcc10f15 -O config-gentoo-sources-4.17 |
