alt Hacker NewsI see this as an expression of the same underlying complaint as Casey Muratori's 30 Million Line Problem: https://caseymuratori.com/blog_0031
Casey argues for ISAs for hardware, including GPUs, instead of heavy drivers. TFA argues for a graphics API surface that is so lean precisely because it fundamentally boils down to a simple and small set of primitives (mapping memory, simple barriers, etc.) that are basically equivalent to a simple ISA.
If a stable ISA was a requirement, I believe we would have converged on these simpler capabilities ahead of time, as a matter of necessity. However, I am not a graphics programmer, so I just offer this as an intellectual provocation to drive conversation.
I generally agree with this opinion and would love to see a proper well documented low-level API for working with GPU. But it would probably result in different "GPU ISAs" for different vendors and maybe even for different GPU generations from one vendor. The bloated firmwares and drivers operating on a higher abstraction level allow to hide a lot of internal implementation details from end users.
In such world most of software would still probably use something like Vulkan/DX/WebGPU to abstract over such ISAs, like we use today Java/JavaScript/Python to "abstract" over CPU ISA. And we also likely to have an NVIDIA monopoly similar to x86.
