[Openchrome-devel] K8M800 artifacts, trac #145, trac #164
Sun Mar 16 04:28:15 PDT 2008
In trac tickets #145 and #164 two people seemingly independently
found kernel commit a0a6dd0b221260be1e3da725e6b49797e5fa7429
(DRM commit 6c04185857694b2293046b7ea1d4515404a740c3) to be the
cause for screen corruptions they see on K8M800 and VN800 chips.

a kernel change that causes this. :)
Is there anything in the diff that leaps at you, Thomas? Or should
the reporters file a bug against DRM so you can look at it later?
The following two statements seem strange to me:
ptr = ((volatile char *)paused_at - dev_priv->dma_ptr) + ...
What are they supposed to do?
