Hi,
I'm a game developer using Unreal Engine 4 everyday and make my own game engine.
I always used fglrx and it worked pretty well but a few month ago "x11-drivers/ati-drivers" gets deleted from portage. Not just frozen or anything just simply deleted.

My problem is: I have a GCN 1.0 (AMD R9M370X - Southern Islands - Cape Verde) which doesn't work with amdgpu (yet?) and according to benchmarks fglrx is still faster than radeonsi.
I also need opengl 4.5 (which include important features like bindless textures) to work but the stable mesa can't give me more than 4.4 at best.

In addition if I follow the official documentation:
wiki.gentoo.org/wiki/Fglrx
It says that I should use AMDGPU-PRO but it's a userland driver based on amdgpu for the kernel land and like I said amdgpu doesn't work with my GPU...


On the amdgpu page is says that my GPU is supported but I tried with linux 4.9, 4.10 and 4.11 I always get a black screen immediately after the driver gets mounted (yes I did enable SI support in the kernel).
My situation is kind of annoying I have to use a mesa, a Xorg-server and a ati-driver that doesn't exist anymore on portage.


I want to stick to "official" drivers so what do I should do ? Download fglrx Xorg and mesa from official website and work without portage ? freeze my portage ? Move to amdgpu with an "unstable" mesa ? If I should move to amdgpu and my GPU should be supported by it what did I missed ?


PS: It looks weird to see no one on internet complaining about that so I'm very sorry if that deletion was my fault...
PPS: I hesitate to post in "Kernel & Hardware" but there is a lot of userland stuff and from where I stand my GPU isn't supported.

You can use a overlay for have ati-drivers (see here), but I think you can have version problem with xorg

Well, using layman didn't crossed my mind... That's good work around.

Would be great if someone can give some advice if I want to go the "official way" and/or about what is happening with amdgpu and GCN1.0 cards (in the case some GCN 1.0 guys like me read this).

fglrx is dead for a long time, older cards are supposed to use the much better radeon opensource driver.

newin,

Until recently I was using amdgpu with a GCN 1.0 card (Oland). I reverted to radeonsi due to loss of audio_over_hdmi with 4.9 kernel.

Concerning black screen issue pls ensure CONFIG_FB is builtin.

Regards.

Which kernel do you have ?

I don't know what you call "much better" but from my experience radeon was always the slowest and was at very least 5 years late. Yes fglrx was unstable sometimes but it was so rare...
But yeah I think I will switch to amdgpu someday to get at least vulkan through RADV and OpenGL 4.6 in the future.

I upgraded 4.4 to 4.9.

Current kernel:

Well, I just tried 4.11 and 4.12 under different configuration and it still doesn't work.
If I put amdgpu in buildin it freese before openRC.
If I put amdgpu in module it blackscreen after openRC.

here is a `cat /usr/src/linux-4.11.2-gentoo-r1/.config | grep AMD`

Code:
# CONFIG_X86_AMD_PLATFORM_DEVICE is not set
CONFIG_CPU_SUP_AMD=y
CONFIG_X86_MCE_AMD=y
# CONFIG_PERF_EVENTS_AMD_POWER is not set
CONFIG_MICROCODE_AMD=y

`cat /usr/src/linux-4.11.2-gentoo-r1/.config | grep CONFIG_FB | head -n 1`
Code:
CONFIG_FB=y


That wasn't the problem.

The above kconfig and dmesg are leftovers from earlier troubleshooting efforts.. (black screen at openrc start but I could login blind, startx brought up desktop.)

btw, are you running on a intel or amd cpu? Your sig says intel, 'CONFIG_MICROCODE_AMD=y' says amd.. just to be clear.
