I just enabled ASTC on Tegra with, effectively, one line of code and got it right on the first try.Do you have any idea how amazing this is?You know. ASTC. The one format that has a non-power-of-two block size. The only format group NVIDIA supports where the block size isn't square.First try. Every single Vulkan CTS test for ASTC passes.On Intel, getting ASTC working was utter hell. We had so many image layout bugs. Block sizes of 4 were assumed all over everywhere. There were x/y mixups that only mattered for non-square blocks. The whole cooncept of a non-power-of-two didn't exist. Our block compressed format handling was also just plumb wrong.Then Lina and I wrote ISL and put a lot of time and thought into how we do layout calculations to avoid a lot of the anti-patterns in the old code. Everything has units. Everything is an isl_extent4d and those have helpers so you aren't banging on them manually. We carefully ensured that the calculation flow only went one direction and we never multiplied and then divided it back out later. ISL fixed so many bugs.With NVK, I wrote NIL which was based on our learnings from ISL. After Daniel helped me port NIL to Rust, I took it a step further and encoded the units in Rust types instead of just suffixes on variable names. This means you have to go out of your way to ever screw up a unit conversion.The result is ASTC in one line of code.

Another week. Another LLM MR that makes no sense and burns maintainer time. Could we all please just stop with this?

Train seat assignment is a register allocation problem. In this essay I will...

Do you have any idea how embarrassing it is when someone from a multi-billion dollar company is like, "We're being on open-source to do this."You realize it's just like this one guy, right? A guy who's not even really getting paid for it. And you have billions.Like, maybe you could fund some of that work? Just a thought...

@gfxstrand LLMs really do supercharge specific kinds of idiocy and blind faith. Before, across all my projects, I would get maybe 0.5 dudes a year who just ran a tool, applied the suggestions blindly and tried to have them merged because "${tool} suggested it".This year I've already seen "IDK why this is here, ${LLM} did it" bunch of times, and it makes me mad as hell.YOU opened the PR, YOU are responsible.
