VirGL Now Capable Of OpenGL 4.1 With Latest Mesa

[dragon321]

I was thinking about Gallium9 for D3D at least, but I suppose that even wine doesn't want to pull in support for it in mainline means there's no chance of VirGL pulling in support for that either. :/

Probably because it's limited for Gallium drivers. On desktop only AMD and Nouveau are using Gallium. Nvidia or Intel don't.

My only point is (from what I can tell) there's not that much work to do to make VirGL caught up with Mesa, compared to other drivers.

your point is wishful thinking

Probably not because Windows uses DirectX for acceleration.

If you want DX acceleration on VirGL then you need to bring some translation from DX to OpenGL/Vulkan (when this driver will get Vulkan support). As I know VirtualBox works the same way - implements DX on OGL thats why you can use DX acceleration on Linux host.

Is that enough for an accelerated desktop / MS office? I'm not talking games...

no hardware driver does any of the rendering. they command hardware to do rendering.

*sigh* You really need to stop taking things so literally, especially where the specifics/accuracy doesn't invalidate the point. Yes, obviously the driver itself doesn't handle the rendering. I'm making a tremendously generalized summary with intentionally vague terminology, to make a quick point. What you said here...

virgl is gallium driver. it does not talk to gallium hardware driver at the host because host does not have to have gallium hardware driver. virgl talks to opengl host driver, i.e. it has to convert gallium back to opengl

...is pretty much just a more accurate way of saying what I meant to say, with more specifics pertaining to Gallium. At least 1 other person seemed to understand the gist of what I meant.

It was implied I meant this summer (specifically, for the northern hemisphere), which I think is a reasonable estimate. Progress for VirGL is very fast, because (I assume) it doesn't actually do any of the rendering.

no hardware driver does any of the rendering. they command hardware to do rendering.

I'm guessing the extensions are just simply redirected (maybe over a virtual network?) to the actual hardware drivers, so it really just comes down to testing if these redirections actually work.

virgl is gallium driver. it does not talk to gallium hardware driver at the host because host does not have to have gallium hardware driver. virgl talks to opengl host driver, i.e. it has to convert gallium back to opengl

I'm guessing there's some behind-the-scenes work done, or else I think this would already have complete feature parity with current Mesa.

your guess would be better with s/some/a lot of/
virgl gallium driver is 3 times smaller than softpipe. but this is only one side of driver

I wonder if you could run Wine's Direct3D over OpenGL on virtualized Windows to get some level of Direct3D support with VirGL.

It makes no sense because we can use DX over Vulkan instead.

This is exactly what VirtualBox does.

It is indeed possible; just replacing the native direct3d dlls with a native build of wine's wined3d.
It's the same as using DXVK on Windows.

the level of abstraction is hurting me, please stop.

Haha.
