Bug#790808: linux: Please enable CONFIG_MMIOTRACE

Source: linux
Severity: wishlist

Dear Maintainer,

Please enable CONFIG_MMIOTRACE.

mmiotrace can provide very valuable information to the nouveau developers. But to enable that, we currently need to rebuild the kernel, and rebuild the nvidia blob against it.

>From ubuntu:

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
