Description Aapo Tahkola 2005-12-09 09:16:15 UTC 
Is suspect this is the cause because everything beyond 64 MB is flashing garbage.
Further the corrupted texture patterns respond to things like window movement.

And yes, this causes severe instability issues.

Hardware: Connect3d Radeon X850 pro

[drm:radeon_cp_dispatch_texture] *ERROR* Invalid destination offset

Starting to make sense...

Couple values off drm:
fb_location c0000000
gart_vm_start c4000000
gart_size 01000000

Hence, gart is not being allocated after textures but on top of them.

Changes gart_vm_start to start at 128 MB.
Comment 8 Michel Dänzer 2005-12-16 01:08:29 UTC 
Why not just add RADEON_CONFIG_MEMSIZE?
Comment 9 Aapo Tahkola 2005-12-17 03:06:07 UTC 
Fixed in drm cvs.
