I have MSI bravo 15 with both integrated and discrete gpu. (I use amdgpu)
Without any xorg configuration I get error Cannot run in framebuffer mode. Please specify busIDs for all framebuffer devices

Astolfo,

Welcome to Gentoo.

Your problem is
Code:
[   101.607] (II) AMDGPU(0): [KMS] drm report modesetting isn't supported.

That means that DRM is (Direct Render Manager) is missing from your kernel.

All the drivers in your list of possible drivers
Code:
[   101.602] (==) Matched amdgpu as autoconfigured driver 0
[   101.602] (==) Matched ati as autoconfigured driver 1
[   101.602] (==) Matched modesetting as autoconfigured driver 2
[   101.602] (==) Matched fbdev as autoconfigured driver 3
[   101.602] (==) Matched vesa as autoconfigured driver 4
except vesa need it.

Thank you NeddySeagoon.

I have sys-kernel/linux-firmware installed and I use binary kernel gentoo-kernel-bin.

Should I compile my kernel (to enable drm)?

Astolfo,

What does
Quote:
zgrep DRM /proc/config.gz
tell?

You need at least
Code:
CONFIG_DRM=y
# CONFIG_DRM_DP_AUX_CHARDEV is not set
# CONFIG_DRM_DEBUG_MM is not set
# CONFIG_DRM_DEBUG_SELFTEST is not set
CONFIG_DRM_KMS_HELPER=y
CONFIG_DRM_KMS_FB_HELPER=y
...
some of those are set by others, so they are not all kernel configuration options.
That's the bits that provide DRM.

You also need CONFIG_DRM_AMDGPU=y or CONFIG_DRM_AMDGPU=m
Code:
# CONFIG_DRM_AMDGPU_SI is not set
# CONFIG_DRM_AMDGPU_CIK is not set
if you have one of those GPUs

Code:
[   101.593] (--) PCI: (3@0:0:0) 1002:7340

You have a Navi 14 [Radeon RX 5500 / 5500M] GPU, so
Code:
# CONFIG_DRM_AMDGPU_SI is not set
# CONFIG_DRM_AMDGPU_CIK is not set
(set off) is a good idea but not required.

Check your kernel and rebuild it if required. xorg cannot work with the amdgpu driver without DRM.

NeddySeagoon,

https://pastebin.com/M1f87BBb - my config

I have:
Code:
CONFIG_DRM=m
CONFIG_DRM_KMS_HELPER=m
CONFIG_DRM_KMS_FB_HELPER=y
CONFIG_DRM_AMDGPU=m
CONFIG_DRM_AMDGPU_SI=y
CONFIG_DRM_AMDGPU_CIK=y


So I guess my kernel is fine?

Astolfo,

That tells me that you are not running the kernel that belongs to that configuration.
That config fragment contradicts missing the missing DRM support supported by xorg.

What does
Code:
uname -a
tell?
The date/time is the build date and time of the running kernel. DOes that look right to you or did you make a newer one?

Is you normal user in the video group?
The groups command will show that. DRM requires direct access to the hardware, and being a member of the video group provides that.

What do you have in /dev/dri/ ?
I get
Code:
$ ls /dev/dri/ -l
total 0
crw-rw---- 1 root video 226,  0 Feb 16  2014 card0
crw-rw---- 1 root video 226, 64 Feb 16  2014 controlD64

Empty is the wrong answer, That would be a kernel problem.
Notice that access to the /dev entries are restricted to root and video group members.

Astolfo,

Code:
[    12.002] (II) xfree86: Adding drm device (/dev/dri/card0)

That's new and was missing before.

xorg should start on its own with no xorg.config
You will get a USA keymap and a right handed mouse but the defaults work.

Please test with no xorg.config file.

Ah ... You have two AMD graphics cards, a Navi 14 [Radeon Pro 5500M] a Renoir.
Both need the amdgpu driver.
You should have both cards in /dev/dri but there is only one.

Remove one card until Xorg works.
You will need an xorg.conf to make a two card setup work and the Device sections (there will be two) will need PCI bus entries so that Xorg can tell which is which.

Gentoo works best when you add to what already works. That keeps the problem space small.

But I cant figure out how to attach amdgpu to this card (which is UNCLAIMED)... I believe it will solve the problem!

Astolfo,

You are going to need to write an xorg.conf file.
Code:
man xorg.conf
will make your eyes glaze over but its all there.

You will need a
Code:
Section "ServerLayout"
to put it all together.
Multiple
Code:
Section "Screen"
are required, one for each physical screen.
Two
Code:
Section "Device"
will be required.

xorgs automatics work for one screen and and one graphics card.
That's why I wanted to know that that worked before we added an xorg.conf to add the rest in.

Be sure your Identifiers in your xorg.conf sections are all unique. That's how xorg puts all the pieces together.

Code:
Section "Device"
    Identifier "navi"
    Driver     "amdgpu"
    BusID     "pci:0@03:00:0"
EndSection
is the bare minimum for the Navi GPU

The Renoir GPU will be similar
Code:
Section "Device"
    Identifier "renoir"
    Driver     "amdgpu"
    BusID     "pci:0@07:00:0"
EndSection


You need the other sections I listed too. The Gentoo Wik covers multiple monitors an one GPU.

Start with one GPU, and make it work multi monitor. Then do the same with the other GPU.
At the end, put the working pieces together.

I have only one monitor, so I used this link https://wiki.gentoo.org/wiki/Xorg/Guide and tried:
Code:
Section "Device"
    Identifier "renoir"
    Driver     "amdgpu"
    BusID      "pci:0@07:00:0"

    Option "Monitor-VGA-0" "main_monitor"
EndSection

Section "Monitor"
    Identifier "main_monitor"
EndSection

Astolfo,

Code:
[   164.485] (II) AMDGPU: Driver for AMD Radeon:
   All GPUs supported by the amdgpu kernel driver
[   164.486] (EE) No devices detected.
[   164.486] (EE)


That says that the amdgpu kernel driver could not detect a GPU at BusID "pci:0@07:00:0"
Either the driver is the wrong one or the BusID is incorrect.

As you are telling Xorg what to do, it won't try auto detection for the bits you have in your xorg.conf

Specifying discrete gpu as a device in xorg.conf I was able to start x however only with hdmi external monitor, so I do believe that the problem is with integrated graphics and with:

Code:
  *-display
       description: Display controller
       product: Navi 14 [Radeon RX 5500/5500M / Pro 5500M]

       bus info: pci@0000:03:00.0
       version: c1

       clock: 33MHz
       capabilities: pm pciexpress msi bus_master cap_list rom

Astolfo,

You are using the stable kernel
Code:
[    0.000000] Linux version 5.4.66-gentoo-x86_64


Try the testing kernel, which is 5.8.x or even the almost ready 5.9.0-rc7

NeddySeagoon,

Thank you very much, it worked!

I really appreciate your help. I installed 5.7.19 (I don't want to go too far from "stable") and it worked!

Thank you very much!
(I should test it for a couple of days, if everything is fine I will add [SOLVED])

Astolfo,

With very new hardware, there may be kernel regressions that stop it working sometime.
Now you have a kernel that works, don't lose it.
By all means try newer kernels but keep 5.7.19 on your boot menu just in case the update breaks something.

A word of warning. The 5.7 kernel has gone from gentoo, so that kernel series is no longer maintained.

What I had in mind was keywording sys-kernel/gentoo-sources to permit portage to install the testing sys-kernel/gentoo-sources.
That's 5.8.12, as I write.
