 Posted: Mon Nov 28, 2022 12:11 pm Post subject: Radeon 7950x - firmware |
 |
|
Hello,
I can't start the graphical environment. I suspect the problem is with the driver.
The graphics card is integrated in the Ryzen 7950x processor.
| Code: | 0f:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Raphael (rev c1)
Subsystem: Gigabyte Technology Co., Ltd Device d000 |
I have not found what chip the graphics card has in this radeon. What firmware should I load?
| Code: |
*- Firmware loading facility
() Build named firmware blobs into the kernel binary
|
What driver and firmware should i use for the integrated card in the cpu? (radeon, amdgpu?)[/code] |

Try
| Code: |
VIDEO_CARDS="amdgpu radeonsi"
|
then
| Code: |
emerge -uDUav @world
|
Plz follow
https://wiki.gentoo.org/wiki/AMDGPU#Kernel
Firmware probably you can find by rebooting and checking
| Code: |
dmesg -t | grep amdgpu | grep firmware
|
Although it will be infinitely simpler to build the drivers as modules (M)
Plz use latest kernel and linux-firmware.

bdronka,
If you use you will get some hex numbers at the end of the first line.
| Code: | | 0f:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Raphael (rev c1) <--- here |
Those numbers are the vendor and device IDs for your GPU, like [1002:73df].
1002 means AMD. Given those numbers, we can discover the rest.
"Raphael" suggests a Zen APU.

Having no where can you discover what chip it is? |

bdronka,
What's supposed to happen is that you drop | Code: | | PCI 1002:164e site:cateee.net |
into your favourite search engine and it tell the kernel symbol you need.
Only it doesn't work.
Nor does seaching cateee.net for Raphael help.
I suspect you need the amdgpu kernel module but it looks like it won't bind to your GPU as it does not 'know' the PCI ID.
I can't find the firmware either.
If you EFI boot, build EFI_Framebuffer into the kernel.
If you BIOS/Legacy boot, choose VESA_Framebuther.
Its harmless to choose both.
Make the amdgpu module as <M> and install linux-firmware.
If the driver loads and finds its firmware, it will tell you in dmesg.
If the driver fails to load, it will be using one of the framebuffers on the console.
If the driver loads but can't find its firmware, the console will freeze at the point the kernel switches to the (broken) amdgpu driver.
It will tell you all about it in dmesg too but you need lo log in via ssh to read it.
The boot will proceed normally but the console will not work.
-- edit --
phoronix suggests that support for your GPU was added mid September 2022 but you need at least a 5.18 kernel.
That means the Gentoo testing kernel an stable, at 5.15.x is too old. New features are not back parted.

Thanks for the comprehensive information.
So I'm going to add an nvidia card for a while |

If the only reason is you want stay on a stable kernel version, then you should know next stable kernel will be 6.1 soon. So, if you change today to an (Gentoo-)unstable kernel 6.0.x and then to 6.1 you will have an unstable kernel only a short time. |

bdronka,
Stable and testing in kernels means two different things to kernel.org and Gentoo.
Gentoo only stables LTS kernels. With a new stable kernel on kernel.org every 10 weeks or so, its too much effort to stable every kernel.org kernel on Gentoo.
If you have an nvidia card in your parts bin by all means use it.
Its more fun and lower cost to try the testing kernel.

| Non-rc kernels are generally quite safe, so the likely worst case of trying a 6.0.x kernel is that it works neither better nor worse than the 5.15.x you are using now. Trying a 6.0.x kernel will almost certainly be faster than installing an alternate video card. |

| VIDEO_CARDS="amdgpu radeonsi" is a correct value for AMD 7950x? |

vitaly-zdanevich,
Yes.
amdgpu gets the correct Xorg driver
radeonsi builds mesa with the 3D support you need.

If you've not already looked, read, learn and inwardly digest the wiki entry for AMDGPU graphics.
