Linux Graphics: NVIDIA and AMD

The Open-Source NVIDIA Driver Will End Out 2019 In Poor Shape Still For Newer GPUs
For the imminent Linux 5.5 kernel cycle we have talked about exciting AMD Radeon and Intel graphics driver changes on deck from Navi OverDrive overclocking to more Intel Tiger Lake and Jasper Lake bits, AMDGPU HDCP support, and other features queued. But what about the open-source NVIDIA "Nouveau" Linux driver?
Sadly, it's been several kernel cycles since there has been anything major to report. In fact, as it stands right now, there haven't been any changes queues from Nouveau into DRM-Next. Earlier this week Red Hat's Ben Skeggs did push a few bits of new code to the skeggsb/nouveau repository but that work hasn't appeared in DRM-Next as of writing nor any indication on the mailing list.

AMDKFD/ROCm GPU Compute Can Work On POWER Systems Like Raptor's Talos II
While NVIDIA graphics in IBM POWER systems have been known to make a powerful combination for supercomputer deployments, for those wanting a libre GPU compute experience can also use POWER with AMD Radeon's open-source driver with a pending patch to the kernel driver.
With various Radeon driver bugs in the open-source stack having been worked out over time that affect the POWER architecture, it turns out the driver stack is good enough on POWER to even enable the AMDKFD (Kernel Fusion Driver) compute support -- which is the kernel component to the Radeon Open Compute (ROCm) stack that runs in user-space.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
