Phoronix: AMDGPU Driver Sees More Fixes For Linux 5.7 Development

Feature work of Direct Rendering Manager (DRM) graphics driver work for Linux 5.7 is winding down now that Linux 5.6 is almost to its sixth release candidate this weekend, but sent in this week by AMD were a few more AMDGPU items though mostly amounting to fixes for their graphics driver...

Are there currently any AMD GPUs with USB Type-C? Or is this for future GPUs?

I really hope this fixes the Navi hard lockup bug. Doubtful though

These sort of issues don't appear all that uncommon with AMD GPUs, always makes me a bit hesitant when someone chimes in that using nvidia proprietary drivers are bad(not that they don't have their own issues) and using AMD avoids those problems.

How long does it usually take for the newer generation AMD hardware to be hassle-free on Linux?

Crashes are normal to some extent. If not doing something very specific (e.g. ffmpeg VAAPI HEVC encoding etc.), the Linux Polaris drivers where extremely stable in my experience. I'd suppose that Navi is not so much different anymore, but I'm open to change my opinion if their are corresponding reports. Of course also specific issues can be unbearable if unlucky.
I don't know why anyone would use Linux with Nvidia if it's not about some specific CUDA working environment etc. Their Windows driver works much better, I'm actually really content with it again.

This isn't normal crashing. It's every day, or multiple times a day, for anyone who experiences it, and it's the same bug. There were also a ton of reports at the original page too, but it got migrated to the link I posted above.

Polaris was extremely stable, I never had any GPU crashes with my RX 580 except when trying to set up an overclock when that's to be expected.

I think amdgpu is generally quite stable, I don't have any navi hardware, which might be different up to now, but a lot of other hardware and no real worrysome problems.

Polaris and Vega are both incredibly stable. Before my 2600X I had a 3200G with Vega 8 integrated graphics, and then I had an RX 580 which is of course Polaris, and it was amazingly stable. I've heard that it took some time to get there though. I'm really hoping the new hire AMD is going to make for a lead kernel developer for amdgpu will spur some action on Navi's stability.

I got my RX5700 back in October and it took my quite some time to get it "somehow" running on an Ubuntu 18.04.x.

I've summed up my frustration over here:

Kernel 5.3 still works quite well with the GPU, but Kernel 5.4 on my 20.04 test setup is a complete dog. It doesn't crash, but gives me 30fps in Shadow of the Tomb Raider. Using the 5.5 mainline Kernel I'm back to the expected 130fps. And don't expected "hassle-free" OpenCL on Navi. Might never happen.
The Ryzen 3700X and the X570 chipset OTOH didn't give me any headaches and worked "as expected" OOTB.
