[ubuntu-x] [PATCH 1/2] UBUNTU: [Config] enable MMIOTRACE for graphics debugging]

[Bryce Harrington]

I see this just went in today - RAOF you might want to plan on kicking
the tires on this and add some docs on how to use it to the appropriate
troubleshooting page on wiki.ubuntu.com/X

Subject: [PATCH 1/2] UBUNTU: [Config] enable MMIOTRACE for graphics debugging

Enable MMIOTRACE to allow us to trace low level card operations.  This is
commonly used to debug graphics issues particularly under Nouveau.
According to the documentation it is a near zero impact when disabled.
