KMS for VirtualBox guest additions?

[Vighy]

Would it be feasible to add Kernel mode setting to the virtualbox driver found in the guest additions (I mean the OSE, obviously )??

I thought about it just because I was thinking about nice projects like wayland that make use of it, but KMS is available just on intel HW; so none with different HW could ever contribute directly to the project, until a driver for their specific HW is done.

So someone may ask: why not directly contribute to the specific HW drivers and leave virtualbox to sun?

a) first of all because it seems to me that virtualbox video driver is smaller and less complex than all the other drivers (since it provides less functionality, but userspace mode setting is exactly the thing I would like to port to kernelspace, nothing more for now)

b) second because, doing so, even people that will not see kms in the short term (like nVidia people, since nouveau is far from getting stable), could help directly to projects like wayland, or fixing bugs related to kms, too.

Is there anyone who knows well how VB video driver works, or can point to references/documents/stuffs sufficient to understand it and how to modify it?

I think the Best place to ask about KMS is in the vb forum http://forums.virtualbox.org/

Let me alter the question slightly ...

Replace all references to 'VirtualBox' with 'VMWare'. I think there might be some lurkers who can comment on that ...

VMWare isn't open source

I will, I just wanted to have some thoughts before registering to another forum, remembering another password and so on

I would like it.... but the sources?? I use virtualbox because it is free. (and I can play with its code )

Sure. But a good number of X / mesa developers are now employed by vmware, so I would expect vmware to start supporting this quickly.

as far as I know they have only bought out tungsten graphics


mesa != tungsten and as far as that goes there are even non tungsten people working on galluim3d ie nouveau and radeon guys

mesa != tungsten

Didn't say mesa == tungsten. I'll still bet you that KMS appears in vmware before virtualbox.

This is for sure if nobody works on it for virtualbox. Since virtualbox IS opensource (well a sort of ) we can this happen before that for VMWare.

But if we do not even try.. it won't happen soon.

I'm more worried about DRI2 and Gallium3D support than KMS.
