where we need to bake the worst hash into the silicon

MMaxine because we live in a society

chairclr•8/7/23, 1:55 AM

that needs to calculate a crc32 hash in a single instruction

khitiara•8/7/23, 1:55 AM

thats another issue with nvorbis btw

khitiara•8/7/23, 1:56 AM

it implements crc32 and mdct itself, mediocrely, not vectorized or optimized

MaxineOP•8/7/23, 1:56 AM

oh my god there's crc32 algorithms that complete in one cycle

khitiara•8/7/23, 1:56 AM

yeah

MaxineOP•8/7/23, 1:56 AM

i'm fucking dead

khitiara•8/7/23, 1:56 AM

its a thing that gets done a LOT in low level network shit iirc

khitiara•8/7/23, 1:56 AM

or similar hashes anyway

khitiara•8/7/23, 1:57 AM

crc is easy to implement in just logic gates btw

MaxineOP•8/7/23, 1:57 AM

networks have a lot of huffman bullshit going on

MaxineOP•8/7/23, 1:57 AM

loads of layers to stop corrupted data from getting too far in

MaxineOP•8/7/23, 1:57 AM

ethernet is just weird

Hardware build: CRC calculation

CRC (cyclic redundancy check) involves some intimidating math. But it turns out that it can all be done with some fairly simple hardware. In this video, I build the hardware to compute and verify CRCs. Previous video on CRC theory is here: https://youtu.be/izG7qT0EpBw

none of this is even remotely silk related

khitiara•8/7/23, 1:57 AM

true that

khitiara•8/7/23, 1:57 AM

should move to general

oh god I'm getting into some cursed stuff rn

Trying to embed WebGPU within an Eto.Forms control

khitiara•8/7/23, 2:20 AM

idk if this applies to webgpu too but afaik the standard practice for the cases where you do that is to render to a texture and then download those pixels from the gpu and copy it over to the control

ritchie ❤•8/7/23, 2:20 AM

Sounds like it'd be slow

ritchie ❤•8/7/23, 2:21 AM

Or at least not speedy enough for a game engine editor window

khitiara•8/7/23, 2:21 AM

relatively, its less slow and more delayed if that makes any sense

ritchie ❤•8/7/23, 2:21 AM

which is what I'm trying to make

Kkhitiara relatively, its less slow and more delayed if that makes any sense

ritchie ❤•8/7/23, 2:21 AM

Delayed is still functionally slow for the user

Kkhitiara idk if this applies to webgpu too but afaik the standard practice for the cases ...

Lyris the Kitori•8/7/23, 2:21 AM

nah thats not the way to do it

ritchie ❤•8/7/23, 2:22 AM

and if the user's me, the user will not tolerate a low effective framerate when designing my game.

ritchie ❤•8/7/23, 2:22 AM

Essentially what I wanna do is take an eto control and somehow get at the native x11, wayland, and win32 window handles

Lyris the Kitori•8/7/23, 2:22 AM

https://github.com/picoe/Eto.Veldrid/tree/master/src
see how its done here

Lyris the Kitori•8/7/23, 2:22 AM

and just adapt to WebGPU

ritchie ❤•8/7/23, 2:22 AM

through this method

private NativeWindowInfo DetermineSystemWindowInfo()
    {
        var result = new NativeWindowInfo();

        IntPtr handle = control.NativeHandle;
        
        
        
        return result;
    }

private NativeWindowInfo DetermineSystemWindowInfo()
    {
        var result = new NativeWindowInfo();

        IntPtr handle = control.NativeHandle;
        
        
        
        return result;
    }

in my engine's INativeWindow interface

ritchie ❤•8/7/23, 2:23 AM

for win32 I need an HISTANCE, and an HWND, both are IntPtrs

ritchie ❤•8/7/23, 2:23 AM

for x11 I need a Display (IntPtr) and a Window (uint)

ritchie ❤•8/7/23, 2:24 AM

wayland needs a Display and Surface, both are IntPtrs

ritchie ❤•8/7/23, 2:40 AM

@baebey I'm lost lol

Lyris the Kitori•8/7/23, 2:40 AM

happens

ritchie ❤•8/7/23, 2:41 AM

I mean the above link doesn't even support wayland

ritchie ❤•8/7/23, 2:41 AM

so that's an issue

Lyris the Kitori•8/7/23, 2:41 AM

i dont think eto does anyway

Lyris the Kitori•8/7/23, 2:41 AM

isnt it gtk3

ritchie ❤•8/7/23, 2:41 AM

I have no idea

ritchie ❤•8/7/23, 2:41 AM

but even then

ritchie ❤•8/7/23, 2:41 AM

wayland aside

ritchie ❤•8/7/23, 2:42 AM

the gtk one in the link above is creating a swapchain

ritchie ❤•8/7/23, 2:42 AM

and not a surface

ritchie ❤•8/7/23, 2:43 AM

but for webgpu I need to create a surface and my only options for creating a surface are

ritchie ❤•8/7/23, 2:43 AM

create a win32 one, create an x11 one, create an xcb one, create a wayland one, create a cocoa one, create an android one, or create an HTML canvas one

ritchie ❤•8/7/23, 3:05 AM

and for x11

ritchie ❤•8/7/23, 3:06 AM

webgpu expects the display as a void* and the window as a uint @baebey

ritchie ❤•8/7/23, 3:06 AM

and the veldrid thing gets both as an IntPtr

private NativeWindowInfo DetermineSystemWindowInfo() { var result = new NativeWindowInfo(); IntPtr handle = control.NativeHandle; return result; }
