Is there any reason that you couldn't implement this on Xorg?

Please read up some more about Java and GCs. Memory allocation and GC are heavily intertwined.

See https://fgiesen.wordpress.com/2012/07/21/the-magic-ring-buff... which takes it even further :)

Indeed I misread. I figured the NMI must have been nested or otherwise they wouldn't have gone through all this trouble just to drop samples :)

Not OP: how would you handle the second interrupt during the interrupt handler here then? I can see how you could use two separate ring buffers for different contexts, but I don't …

One thing wasn't clear for me in the article: is there only one such ringbuffer defined by the kernel or can the eBPF program specify as many ringbuffers as it wants?

I give up, tell me the AABB trick please

The entire point of the article is that you cannot throw from a destructor. Now how do you signal that closing/writing the file in the destructor failed?

Maybe we can even find some correlation in the bit pattern of the input and the Boolean table!

The pixel position has to be known, how else are you rasterizing something?

Their current OpenGL 4.1 actually does run on top of metal making it even more blatantly obvious that they just don't want to.

I'm not sure exactly what you mean, but you can both output line primitives directly from the mesh shader or output mitered/capped extruded lines via triangles. As far as other pla…

That said MSVC,GCC and clang all implement it to allocate an exact value.

Can you point me to some good middleware then? I haven't been able to find any.

Any kind of relative/offset pointers require negative pointer arithmetic. https://www.gingerbill.org/article/2020/05/17/relative-point...

You can still statically link all your own code but dynamically link libc/other system dependencies.

Yeah it's a shame that to go from your idea to something that's 'general' (ie just some arbitrary arguments) you need to write this arcane garbage.

std::bind is bad for him for the same reasons std::function is bad though

What he shows here is 75% of c++26's std::function_ref. It's mainly missing variadic arguments and doesn't support all types of function objects. https://github.com/TartanLlama/fun…

But you can embed this 1 byte lock into other bigger objects (eg. high bytes of a pointer). With 4 byte locks your run into the exact same false sharing issues.

Because the only way to do metaprogramming in C++ is via the type system. Thismakes it so you need to implement 'functions' as types.

Guess: it's too much water to cool down in a small local reservoir.

I would allow it, given they physically write down all N square root on a piece of paper.
