DRI init changed memory map

[forum1793]

I noticed for some time that xorg.0.log gives warnings about changed memory map for dri under exa section. Considering earlier mention of memory bug for 3d, are these warnings related?

Hardware: hd3200 (780g) integrated.
drm is agd5f's 3D branch
mesa is r6xx-rewrite branch
edit: Using xf86-video-ati

Relevant Warnings.

This has nothing to due with EXA, and can be safely ignored. Both the ddx and the drm have to have a consistent view of the memory controller setup. So after the drm init has run the ddx updates its view.

What "memory bug for 3d" are you referring to?

What "memory bug for 3d" are you referring to?

That comment stemmed from brdgman posts. Two might have been:

1 (http://phoronix.com/forums/showpost.php?p=80526&postcount=20) and 2 (http://phoronix.com/forums/showpost.php?p=81085&postcount=75)

There may have been others.

I used the 3D reference with those related to glxinfo lockups.

Edit: I meant glxgears lockups. glxinfo works ok.

Thank you for response.

That's an issue in the work-in-process 3d driver as far as we know.
