Canonical's Mir Patches Are Breaking RADV With Stock Mesa On Ubuntu
If you have been trying to use the RADV Radeon Vulkan driver that's packaged for Ubuntu but find it not working, chances are it's caused by Canonical's patches for Mir support.
RADV developer David Airlie of Red Hat today sent out a notice that Canonical's Mir patches in their Mesa packages are breaking the RADV driver. Ubuntu isn't shipping Vulkan drivers by default yet but ANV and RADV can be easily obtained on Ubuntu Linux systems via sudo apt install mesa-vulkan-drivers for the RADV/ANV drivers built against their stock version of Mesa.

VC5 Gallium3D OpenGL Driver Is Starting To Get Fit
Broadcom's Eric Anholt has remained busy in bringing up the VC5 Gallium3D driver.
Anholt has added occlusion query support to this driver for next-gen Broadcom graphics hardware as well as improving the debugging output, fixing some crashes, and fixing other OpenGL functionality with this driver. It's been a busy time for him in bringing up this new driver stack as well as continuing to maintain the VC4 driver that continues to be most notably used by the current range of Raspberry Pi ARM boards.

Radeon VCN Encode Support For RadeonSI Gallium3D
Earlier this year patches were posted and merged for VCN video decode support with RadeonSI/Gallium3D while now patches are coming from AMD for wiring up VCN video encoding support.
VCN is a new media block with the upcoming Raven Ridge (Zen+Vega) APUs for both video encode and decode. In the past there was UVD for video decoding and VCE for video encoding while now VCN offers both multimedia encode/decode unified functionality via this new implementation. As mentioned, the VCN video decode bits are already in Mesa while the video encode pieces are now under review.
