lavapipe reporting Vulkan 1.1 (not compliant)

The lavapipe vulkan software rasterizer in Mesa is now reporting Vulkan 1.1 support.

It passes all CTS tests for those new features in 1.1 but it stills fails all the same 1.0 tests so isn't that close to conformant. (lines/point rendering are the main areas of issue).

There are also a bunch of the 1.2 features implemented so that might not be too far away though 16-bit shader ops and depth resolve are looking a bit tricky.

If there are any specific features anyone wants to see or any crazy places/ideas for using lavapipe out there, please either file a gitlab issue or hit me up on twitter @DaveAirlie

    I was thinking that lavapipe would be a intereting tool to use for VFX companies who want to write vulkan compute shader based programs, want to run those programs on their massive CPU render farms. Right now, if companies want to invest in dev time for GPU accelerated programs, it has to be justified by having the hardware in place. But then they won't buy the hardware because its seen as a risk. Being able to write software once and have it run on both CPU/GPU is a plus (like opencl which isn't really used in vfx much).

      I was thinking exactly what Daniel was thinking. Also a big stretch, but the raytracing extensions come to mind also but probably way out of scope.

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

radv: vulkan video encode status

Vulkan 1.3.274 moves the Vulkan encode work out of BETA and moves h264 and h265 into KHR extensions. radv support for the Vulkan video encode extensions has been in progress for a while. The latest branch is at [1]. This branch has been updated for the new final headers. Updated: It passes all of h265 CTS now, but it is failing one h264 test. Initial ffmpeg support is [2].

radv: vulkan av1 video decode status

The Khronos Group announced VK_KHR_video_decode_av1 [1], this extension adds AV1 decoding to the Vulkan specification. There is a radv branch [2] and merge request [3]. I did some AV1 work on this in the past, but I need to take some time to see if it has made any progress since. I'll post an ANV update once I figure that out. This extension is one of the ones I've been wanting for a long time, since having royalty-free codec is something I can actually care about and ship, as opposed to the painful ones. I started working on a MESA extension for this a year or so ago with Lynne from the ffmpeg project and we made great progress with it. We submitted that to Khronos and it has gone through the committee process and been refined and validated amongst the hardware vendors. I'd like to say thanks to Charlie Turner and Igalia for taking over a lot of the porting to the Khronos extension and fixing up bugs that their CTS development brought up. This is a great feature of having
