Official Bindless Graphics feedback thread

Nope, but don't let that deter you ;-)

I've been playing around with this extension, but one thing I was somewhat curious about...

In the spec example for "GL_NV_vertex_buffer_unified_memory", it lists this function:

// get the address of this buffer and make it resident.
GetBufferParameteri64vNV(target,BUFFER_GPU_ADDRESS ,&gpuAddrs[i]);

But I cannot find any such function as having been added in any of these extensions, although there is a similar function called GetBufferParameterui64vNV from the "GL_NV_shader_buffer_load" extension.


I have been using this second one since it seems to more or less work... well for a few minutes, and then the driver randomly crashes. I'm creating lots and lots of these buffers, probably at least 20k, perhaps there is a limit or something? For some reason when I use occlusion culling I crash much faster, with OC in use the program lasts about 10 seconds, with it off, more like a minute or so.

Yes, it's supposed to be GetBufferParameterui64vNV (with a "u"), that's a typo.

Can you provide a repro app for the crash?

[Fitz]

jeffb I sure can, do you need source or just a .exe? What should I send it to? Hopefully it is just something stupid I did..

Fitz, I sent you a private message with more info

We released 185.81 beta drivers today, including for notebook. Please use those drivers if you are going to experiment with bindless graphics.

I'm probably missing something obvious, but where?

developer.nvidia.com: ver 180.51 (Apr 1) Linux
nvdeveloper.nvidia.com: ver 182.65 (Apr 29) Win

<u>EDIT</u>:
Never mind. Found it:
http://www.nvidia.com/Download/betadrivers.aspx aka
http://www.nvidia.com/Download/Find.aspx?lang=en-us

Just a heads-up: developer.nvidia.com->Drivers->Download Latest Drivers doesn't get you the latest drivers. Google NVidia beta drivers to get the above links.

Wow. I own the NVIDIA DevZone site and didn't know about this annoyance. I'm going to change the "Drivers" link on the left side to just go to http://www.nvidia.com/Download/Find.aspx from now on. Hopefully that will help!

Now we're seeing some real changes

Anyway, this extension seems really cool. Might be some time until I get the time to start working on it for the GL renderer but I almost can't wait for the moment

We now have to push ATI/AMD to implement it also. I actually have real hopes that it will, since this is a major step forward in GPU programmability.

I don't hold out much hope; they don't have as many resources when it comes to developer stuff as NV and certainly not as many much when it comes to driver dev.

The state of their dev. pages alone should be a good clue to this...
