AMD Sends In Initial Batch Of Fixes To Linux 5.4 - Includes Dali Support
While just yesterday the big DRM feature pull was sent in for Linux 5.4, AMD has also volleyed out their initial batch of fixes for this next version of the kernel.
This new AMDGPU pull isn't strictly fixes but as anticipated does include the recently reported Dali APU support. Dali along with Renoir -- also newly-supported in Linux 5.4 -- are some of AMD's 2020 APUs. Dali will be targeting the lower-end of the spectrum it's expected for value mobile/embedded. From the driver code, Dali looks like a newer revved version of the current-gen Picasso APUs. Both Dali and Renoir are based on the Vega architecture.

Linux Plumbers Conference 2019, part 2
Pain points and missing pieces with Wayland, or specifically GNOME Shell:
GNOME Shell is slower
Synergy doesn't work(?) - needs to be in the compositor
With Nvidia proprietary driver, mutter and native Wayland clients get GPU acceleration but X clients don't
No equivalent to ssh -X. Pipewire goes some way to the solution. The whole desktop can be remoted over RDP which can be tunnelled over SSH.
No remote login protocol like XDMCP
No Xvfb equivalent
Various X utilities that grab hot-keys don't have equivalents for Wayland
Not sure if all X's video acceleration features are implemented. Colour format conversion and hardware scaling are implemented.
Pointer movement becomes sluggish after a while (maybe related to GC in GNOME Shell?)
Performance, in general. GNOME Shell currently has to work as both a Wayland server and an X compositor, which limits the ability to optimise for Wayland. -

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. |
