« Last post by pocock on March 20, 2025, 12:38:07 pm »I'm using Fedora right now and my impression is they just don't do testing in general,
Fedora users and even the Fedora Developers are the testers. Unpaid testers for Red Hat.

GPU Compute / Accelerators / Re: Intel Arc A770 - failed experiment
« Last post by Hasturtium on March 20, 2025, 10:48:25 am »It's been 2 years and ... unfortunately the driver still does not support non-x86.
i915's never getting rearchitected for non-x86, but aarch64 reportedly runs Arc with a few caveats using Intel's xe driver. There's nothing it offers that my W6600 doesn't do well enough for my needs at this point, but I'd like to think it'll work since Power9/Raptor's PCIe implementation's apparently less warty.

« Last post by lepidotos on March 20, 2025, 08:20:23 am »Looking at the history of kernel performance changes in Fedora 37, I get the impression that no one does performance testing before releasing a kernel. The variability is high. It's a shame that Fedora developers don't see this.
I'm using Fedora right now and my impression is they just don't do testing in general, like for example shipping GIMP 3 with no way to go back without shipping one of its dependecies (babl 0.1.112, which looking at the tracker page still isn't released for Fedora).

Operating Systems and Porting / Re: [NEWS] Fedora 42 Beta
« Last post by lepidotos on March 20, 2025, 08:15:23 am »Honestly, for daily use, I don't really have a problem with Wayland. I used to have a lot more of them but it seems like there's been a lot of work done to make it a lot more seamless, but I'm also just a desktop user and any server stuff I do probably won't have a GUI running. I just wish there was something as good as TDE for it, Plasma is fine, just not as full featured and robust ime.

It's the BMC chip that needs to be flashed prior if it's blank/corrupted.

GPU Compute / Accelerators / Re: AMD OpenCL / ROCm
« Last post by lepidotos on March 19, 2025, 11:36:29 am »My takeaway is that if you want to do reasonably portable GPGPU stuff learn WebGPU/Vulkan compute shaders. You can do also GPGPU stuff with opengles/webgl with "transform feedbacks" but its extremely limited and a total nightmare, speaking from experience.
Now if only the Blender team would do that. I do hear they are for viewport and Eevee, but Cycles depends on HIP if you're not using CUDA or CPU. Though I suppose render times shouldn't be too bad on the CPU in this case...
