Linux Support Expectations For The AMD Radeon RX 6000 Series

[mdedetrich]

Good work on AMD for releasing what seems to be like the first time in 10 years GPU's that are able to compete with NVidia across the entire consumer GPU market segment. There are some areas where the AMD GPU's seem worse (no mention of raytracing so its likely that it won't be as good as ampere, also their version of DLSS is not likely going to be as good but will be more easily applicable since it doesn't require game devs to specifically train their game on NVidia's super computer to get the neural model for upscaling).

The main thing that AMD needs to fix now is issues dealing with enterprise/scientific applications, i.e. the sorry state of OpenCL and virtualization.

I would not say virtualisation is a problem on the AMD side. There is quite a problem with how hard with commonly used virtualization software it is to perform a PCIe hot reset this does cause administrators running Nvidia solutions who don't fully know what they are doing to be rebooting servers more often than they should to fix Nvidia lock ups as well.

Baco reset different Nvidia enterprise cards have required special software run to reset them as well. This is more of a education problem. For how often quirked up cards happen with Nvidia or AMD or intel or other vendors resulting in making a reset card VM to fix makes you wounder if VM solution providers should come up standard for vendors to provide quirked hardware reset images.

The reality is AMD cards issues with virtualization is not unique to AMD cards or AMD made parts. Problem for all hardware vendors is once quirked hardware is at customer recalling it is normally not a option so has to be software patched one way or the other. Its really interesting how bad virtualisation solutions handle software patching of hardware quirks.

Virtualisation is a two party problem. 1 hardware vendor has to attempt to make the most friendly card they can. 2 the virtualisation solution need to have a decent system to deal when hardware vendor does not succeed.

I managed to play for 2 hours without crashes last week, so good job AMD.
I can actually use my RX 570 for games, wasnt true for the last 2.5 years. So I might buy a RX 6000 in ~3 years.

They completely forgot about Vulkan!

Khronos! Please make Vulkan Magma X next!

If you haven't already, check your thermals. Polaris cards tend to have a higher than necessary voltage which can make your GPU run hot and throttle, leading to lackluster performance and possible stability issues. Aside from actual bugs other people were also reporting, almost all my early RX 580 issues were high voltage and thermal related.

Before I figured my voltages out and got my thermals under control I thought the 580 was a lemon. Now it's a beast. That's half of why I'm wanting a lower-power midrange GPU from the 6000 generation that's around the same performance of a 580. The other half is I'll be at 1080p60 until I can find an affordable 49" 1080p or better FreeSync TV...just no point in having a GPU made for anything better than 1080p60 since I game on my TV at that resolution.

Anyone got Resizable BAR working?

Mine is only like this: [ 5.438633] [drm] Detected VRAM RAM=4096M, BAR=256M

Zen 1, Fiji Fury.

You need to enable a specific BIOS feature often called "I/O above 4G" or something. It works fine for me on Zen 1 with Polaris. If your BIOS setup doesn't have it, I think you are SOL.

Yeah, I can't find anything like that. In which section is it in your BIOS setup?

Yes, but there is that software thing that should steer and control the hardware... lets just call this a "driver" for no apparent reason.
The windows "driver" runs stable, while on linux I have to write some values in sysfs to limit the powerdraw to 60% of the max specifation.

For my next system I will look at a AMD APU and an external Nvidia Card for running under https://looking-glass.io/

will the shared memory business on linux work with older hardware than announced for windows (bios providing ofc)?

i.e. a ryzen 3000 and/or a rdna1 card...
