radv on Ubuntu broken in distro packages

It appears that Ubuntu mesa 17.2.2 packages that ship radv, have patches to enable MIR support. These patches actually just break radv instead. I'd seen some people complain that simple apps don't work on radv, and saying radv wasn't ready for use and how could anyone thing of using it and just wondered what they had been smoking as Fedora was working fine. Hopefully Canonical can sort that out ASAP.

    You can get working Vulkan drivers on Ubuntu with this PPA:

    Do they know? https://bugs.launchpad.net/ubuntu/+source/mesa has only one bug mentioning radv, and it's not about radv.

vulkan video decoding: radv status

I've been working the past couple of weeks with an ffmpeg developer (Lynne) doing Vulkan video decode bringup on radv. The current status of this work is in a branch[1]. This work is all against the current EXT decode beta extensions in the spec. Khronos has released the final specs for these extensions. This work is rebased onto the final KHR form and is in a merge request for radv[2]. This contains an initial implementation of H264 and H265 decoding for AMD GPUs from TONGA to NAVI2x. It passes the basic conformance tests but fails some of the more complicated ones, but it has decoded the streams we've been throwing at it using ffmpeg. Building: git clone https://gitlab.freedesktop.org/airlied/mesa git checkout radv-vulkan-video-prelim-decode mkdir build meson build -Dvulkan-beta=true -Dvulkan-drivers=amd -Dvideo-codecs=h264dec,h265dec --prefix=<prefix> cd build ninja ninja install Running: export VK_ICD_FILENAMES=<prefix>/share/vulkan/icd.d/radeon_icd.x86_64.json

LPC 2022 Accelerators BOF outcomes summary

 At Linux Plumbers Conference 2022, we held a BoF session around accelerators. This is a summary made from memory and notes taken by John Hubbard. We started with defining categories of accelerator devices. 1. single shot data processors, submit one off jobs to a device. (simpler image processors) 2. single-user, single task offload devices (ML training devices) 3. multi-app devices (GPU, ML/inference execution engines) One of the main points made is that common device frameworks are normally about targeting a common userspace (e.g. mesa for GPUs). Since a common userspace doesn't exist for accelerators, this presents a problem of what sort of common things can be targetted. Discussion about tensorflow, pytorch as being the userspace, but also camera image processing and OpenCL. OpenXLA was also named as a userspace API that might be of interest to use as a target for implementations.  There was a discussion on what to call the subsystem and where to place it in the tree. It was ag

lavapipe Vulkan 1.2 conformant

The software Vulkan renderer in Mesa, lavapipe, achieved official Vulkan 1.2 conformance. The non obvious entry in the table is  here . Thanks to all the Mesa team who helped achieve this, Shout outs to Mike of Zink fame who drove a bunch of pieces over the line, Roland who helped review some of the funkier changes.  We will be submitting 1.3 conformance soon, just a few things to iron out.
