Dave Airlie Linux Graphics blog

After much back and forth and hoops jumping, I can finally reveal nouveau/nvk running on a NVIDIA Spark box.

Software Engineering Radio is a podcast for people in IT/development with over 700 episodes across many topics over 20 years.

I'm doing a podcast recording this week, so I wanted to run some numbers so I could have some facts rather than feels.

This topic came up at kernel maintainers summit and some other groups have been playing around with it, particularly the BPF folks, and Chris Mason's work on kernel review prompts[1] for regressions.

Just to keep up some blogging content, I'll do where did I spend/waste time last couple of weeks.

F43 picked up the two patches I created to fix a bunch of deadlocks on laptops reported in my previous blog posting.

I had a bug appear in my email recently which led me down a rabbit hole, and I'm going to share it for future people wondering why we can't have nice things.

AMD have announced the end of the AMDVLK open driver in favour of focusing on radv for Linux use cases.

One of my pet peeves around running local LLMs and inferencing is the sheer mountain of shit^W^W^W complexity of compute stacks needed to run any of this stuff in an mostly optimal way on a piece of hardware.

Blog posts are like buses sometimes...

I should have mentioned this here a week ago.

The Vulkan WG has released VK_KHR_video_decode_vp9.

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.

Vulkan Video AV1 decode has been released, and I had some partly working support on Intel ANV driver previously, but I let it lapse.

The Khronos Group announced VK_KHR_video_decode_av1 [1], this extension adds AV1 decoding to the Vulkan specification.

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.

Linus has pulled the initial GSP firmware support for nouveau.

Sriram invited me to the oneAPI meetup, and I felt I hadn't summed up the state of compute and community development in a while.

The initial NVK (nouveau vulkan) experimental driver has been merged into mesa master[1], and although there's lots of work to be done before it's application ready, the main reason it was merged was because the initial kernel work needed was merged into…

I recently came across tinygrad as a small powerful nn framework that had an OpenCL backend target and could run LLaMA model.

Thanks for all the suggestions, on here, and on twitter and on mastodon, anyway who noted I could use a single fd and avoid all the pain was correct!

Mike nerdsniped me into wondering how hard sparse memory support would be in lavapipe.

F38 just released and seeing a bunch of people complain that TF2 dies on AMD or other platforms when lavapipe is installed.

There are plans for nouveau to support using the NVIDIA supplied GSP firmware in order to support new hardware going forward The nouveau project doesn't have any input or control over the firmware.

While going over the AV1 a few people commented on the lack of VP9 and a few people said it would be an easier place to start etc.
