This chip has no 3D engine, what would mesa be supporting in it?

Comment 2 antonella 2012-01-20 09:10:28 UTC

Could we have a /dev/dri/card0 entry for this card?
I tried to run an EGL app under xorg on this card and work fine.
But when i tried to run without X with EGL_PLATFORM=drm or fbdev doesn't work because i think it cannot open /dev/dri/card0. The same code works fine on intel/radeon/nouveau on console without X.

Is there any solution or workaround? The kernel seems that doesn't load the mga module because doesn't recognize this pci id.

Comment 3 Alex Deucher 2012-01-20 09:13:31 UTC

There is no KMS driver for mga cards.

Comment 4 Dave Airlie 2012-01-20 09:28:19 UTC

This card has no EGL capabilties to expose.

Unless the application is going to run on top of a sw rendering EGL stack.

But there is no KMS driver for this card at the moment to even do that on top off.

Comment 5 antonella 2012-01-20 10:12:56 UTC

Thank you David. 
As i understand if there is no kms driver for this card i think that there is no way to run this application out of an xserver session (i.e. in a gnome terminal) also if i want to go on software rendering?

Comment 6 Alex Waite 2013-09-18 11:41:34 UTC

So, it seems that there is a KMS driver now for the MGA200eW card (thanks to you Dave :-). Any way this can be supported, even if it's just for software rendering?

This card is "video memory" = 0，framebuffer can't used! Why!
