Quoting: TuxeeJust tried the live image of Manjaro 20.0rc2 with a kernel 5.6.5 (didn't check the Mesa details, but I assume 20.0.4) - gave me unbearable screen flickering (never seen that before) and a whole bunch of powerplay errors in the syslog. I'll try a proper install once I find enough time, but the live image was a letdown.
You might want to skip Kernel 5.6.5 altogether, it was released with an AMDGPU regression that prevents reboot/shutdown. The issue has been fixed in 5.6.6.

See here: https://bugs.archlinux.org/task/66305
Well, mainline 5.6.5 has been working fine on my Ubuntu 20.04 during the limited time I spent with it. 5.6.6 has yet to arrive in the repos.

It's in the repos now, but I didn't have any trouble with 5.6.5 either. Must be specific hardware only. But 5.6.6 does include another powerplay fix, so might be worth it to you in any case.

Quoting: Avehicle7887I don't know if this might help but I just noticed the AMD firmwares have been updated in the linux-firmware git: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/
By the way, is it possible to revert changes from this git and go back to previous linux-firmware?
I installed it (sudo cp -va amdgpu/ /lib/firmware/ and sudo update-initramfs -u, according to [this article](https://www.phoronix.com/scan.php?page=news_item&px=Ubuntu-19.10-Radeon-RX-5700) ) on my Linux Mint 19.3 and now I am getting a lot of warnings "Possible missing firmware /lib/firmware/amdgpu/ ... for module amdgpu" every time something is using update-initramfs (e. g. every time I am installing new kernel).

That command seems ok, to be safe it's probably better to open up a gui as sudo and copy paste all the amdgpu firmware in /lib/firmware/amdgpu

The errors you're getting in terminal indicate that those files are not being found.

You'll get those warnings even with the default firmware package if you install a recent kernel. They're harmless as long as you're not missing firmware required by your own hardware.

I checked both linux-firmware-20200316 from git and linux-firmware_1.186 from ubuntu and I don't see arcturus and navi12 files that I miss in amdgpu folders. So, nothing to copy...

There are no major problems, so I think it's fine. And if it's about kernel, not firmware itself, I think I just leave it like this. Thanks.

In terms of stability, what's the current status of RX 5700 or Navi in general?

There are rumors of RX 5300 and I'm interested in low end GPU's.
Tuxee 29 May 2020

I would not recommend it.

My RX 5700 works fine on Ubuntu 18.04.4 with Mesa 20.0 and two displays, but pretty much all other combinations (Ubuntu 20.04 with Kernels 5.4 to 5.6, Mesa 20.0 and various firmware versions) run into hefty problems: long boot times, screen flicker, crashes, etc.
It's not an Ubuntu thing since a live Manjaro image exhibited the same symptoms.
It's not a hardware thing since my Ryzen 7/X570/RX 5700 combo shows the same problems as my Ryzen 5/B450/RX 5500XT.
This is however only valid if you use more than one screen.
I've attached my Ryzen 5 setup to a single 4k display and everything ran without any hiccups for hours. Connect a second display and everything goes south.
This has been my experience so far but they are closely matched by these bug reports (the first issue was reported nearly 8 months ago)

I'm on Manjaro Testing, with a dual screen setup (Screen, drawing tablet and Tv) all in 1080p but 1 hdmi + 1 Dp so not the same situation as Tuxee. Everything is silky smooth, no flicker, no crash or other problems so I can only recommend.

I need to buy another DP to Hdmi converter and try to reproduce this dual screen problem.
wolfyrion 9 Jun 2021
I am on Manjaro with FULL AMD Hardware and an RX 6900 XT on 4x Displays - with the latest MESA drivers and everything is running more than fine.

At the beginning I had some weird problems with my GPU but they got fixed with the newest Mesa Drivers and kernel release.

Also I remember I had a very weird problem like very slow startups and weird behavior of my pc and that was because of my USB HUB - took me some time to find the problem. Replaced it and got industrial usb hub.

In the past I had also PSU Issues so I always go with 1000 W or 1500 W and always with the top brands like be quiet! Dark Power Pro 12 1500W.

Running full AMD system here.

5800X CPU
RX 6800 (non-XT)
Mesa 21.1.2
Kernel 5.11.22

Running 2x 2560x1440 monitors both connected via DisplayPort. Never had any issues even when I was on Mesa 21.0.x

Thanks wolfyrion and Avehicle7887 for posting that! My 6900XT is currently in the mail (switching from an RTX 2080 Ti) and I was getting worried, looking through the forum for tips, that I had made an expensive mistake! I'm already on Mesa 21.1.3 and kernel 5.12.14, so hopefully everything will be fine :)

Posted some Sapphire Pulse RX 6800 XT results here and here. It runs perfectly so far.

Kernel: 5.13.
Desktop operation Mesa: 21.1.2.
Gaming Mesa: main branch.

I will mention: upgrade your BIOS before you plug in your card! I couldn't get the BIOS to boot before that and now I have to fix GRUB because the update hosed UEFI, so do remember that extra step if you're getting one of these lovely new cards.

You can also enable resizable BAR in UEFI for better performance with the new card.

lspci -vv gives me this after it's enabled:

        Capabilities: [200 v1] Physical Resizable BAR
                BAR 0: current size: 16GB, supported: 256MB 512MB 1GB 2GB 4GB 8GB 16GB

I had done that already actually, but it turns out I also needed to disable CSM support for it to take effect. So, thanks for making me double check!

Side-note, I'm really surprised at how much of a difference an AMD card makes in just standard use! The system boots faster, X starts faster, windows switch faster (on bspwm, no less) and fonts somehow look better! (there seems to be a minor difference in DPI scaling, but it really does look better).

I gotta say, I'm very impressed! Also, being able to run Resident Evil 2 HD at high settings without being able to hear the GPU is really quite something :D
I know the card I got is overkill in general (PowerColor RX 6900 XT Ultimate), but I still wasn't expecting this level of greatness and difference coming from a 2080 Ti!
Shmerl 5 Jul 2021
I had a bit of rough time with Sapphire Pulse RX 5700 XT in the past, but I'm surprised how well their Pulse RX 6800 XT runs out of the box.

In general though when I switched from Nvidia to AMD (in Polaris time still with RX 480) it felt very good indeed because of much better integrated experience.

I would like to enable the resizable BAR, but enabling it causes my PCI-E Wifi card to stop working. It is then no longer detected by the system until I disable it again.

If it's Intel (probably the only decent WiFi driver), you can open a bug in the kernel bug tracker.
Dragunov 9 Jul 2021
Well, the problem is that it happens in Windows 10 as well. Its a TP-Link Archer T5E and it is using an Intel Chip. The PC works great as it stands, so I'm not too worried about it.
