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.

On Rust, Linux, developers, maintainers

There's been a couple of mentions of Rust4Linux in the past week or two, one from Linus on the speed of engagement and one about Wedson departing the project due to non-technical concerns. This got me thinking about project phases and developer types. Archetypes: I will regret making an analogy, in an area I have no experience in, but let's give it a go with a road building analogy.   Let's sort developers into 3 rough categories. Let's preface by saying not all developers fit in a single category throughout their careers, and some developers can do different roles on different projects, or on the same project simultaneously. 1. Wayfinders/Mapmakers I want to go build a hotel somewhere but there exists no map or path. I need to travel through a bunch of mountains, valleys, rivers, weather, animals, friendly humans, antagonistic humans and some unknowns. I don't care deeply about them, I want to make a path to where I want to go. I hit a roadblock, I don't focus...

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 ...

vulkan video decoding: anv status

After cleaning up the radv stuff I decided to go back and dig into the anv support for H264. 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. This contains an initial implementation of H264 Intel GPUs that anv supports. I've only tested it on Kabylake equivalents so far. It decodes some of the basic streams I've thrown at it from ffmpeg. Now this isn't as far along as the AMD implementation, but I'm also not sure I'm programming the hardware correctly. The Windows DXVA API has 2 ways to decode H264, short and long. I believe but I'm not 100% sure the current Vulkan API is quite close to "short", but the only Intel implementations I've found source for are for "long". I've bridged this gap by writing a slice header parser in mesa, but I think the hw might be capable of taking over that task, and I could in theory dump a bunch of code. But the programming gu...
