Vega-Based Renoir APU Has The Same VCN Video Encode/Decode Block As Navi

The next-generation AMD "Renoir" APU is turning into being an interesting successor over the existing Picasso APUs. While at first it was a letdown finding out that the APU is based on Vega and not their newer Navi architecture, follow-on open-source Linux patches have continued to show that it's more than a facsimile and in some areas like display and multimedia has blocks in common with Navi.

AMD Renoir APUs Bringing "DCN 2.1" Display Engine

Raven Ridge APUs brought the DCN 1.0 "Display Core Next" engine, Navi GPUs upped that to a DCN 2.0 implementation for the display engine, and now the Renoir APUs are ushering in DCN 2.1. This is a bit interesting particularly with Renoir being a Vega-based GPU and not Navi as one would have hoped prior to the Vega confirmation in the earlier patches.

AMDGPU To Allow Memory Re-Clocking Soon For Multi-Monitor Setups

Currently the AMDGPU Linux kernel driver doesn't automatically adjust the video memory clock speeds when running a multi-monitor setup since it's more complicated to gracefully handle when scanning out to two or more displays. But a set of currently experimental patches will allow memory clock switching support on multi-monitor setups with the AMDGPU DC code.

AMD Posts A New Slide Deck Outlining The RDNA Architecture

Last week AMD published their RDNA instruction set architecture documentation. That's a bit heavy reading unless you are a driver developer or low-level engine developer, but for those wanting a bit of a higher-level look at AMD's new RDNA graphics architecture, today they uploaded a new slide deck.

AMD Sends Out Linux Kernel Driver Support For Navi 12 GPUs

While we've already seen the RADV Vulkan driver land their slated support for Navi 12 GPUs on top of the recently launched Radeon RX 5700 "Navi 10" graphics cards, today is the first time we're seeing patches from AMD to wire in the support to the AMDGPU DRM Linux kernel driver for this next iteration of Navi.

AMDGPU/AMDKFD Queue Up Early Linux 5.3 Fixes For Navi & More

While the Linux 5.3 kernel merge window isn't even over until this weekend when it will kick off with 5.3-rc1 and headlining new features like Radeon RX 5700 series support, AMD has already sent in a batch of AMDGPU/AMDKFD fixes. Making these fixes notable are some early fixes around the new open-source Radeon RX "Navi" support.
