This value interacts with some registers we don't currently know how to program properly ourselves. The default of 5 that we were using matches what the VBIOS on early DP cards do, but later ones use 6, which would cause nouveau to program an incorrect mode on these chips.

TUNABLE
The following parameters should be tunable at compile time. Some of them
exist as sysctls too.
This is far from complete
Item Description
