[Nouveau] [PATCH v5 00/20] Engine Reclocking Fixes for Fermi-Maxwell2

[karol herbst]

patches are on my reclocking_part_1 branch and I already fixed the
commit message of patch 3 there.

> temperature change, so that the more reviewed parts can be merged in
> faster.
>
> This series fixes a lot of Engine reclocking issues found on Fermi, Kepler
> and all Maxwell generation GPUs. It does _not_ fix memory reclocking on
> Fermi.
>
> It mostly contains of simple fixes or simple patches without affecting
> current code.
>
> As a bonus point, it indeed enables memory and engine reclocking on maxwell1
> GPUs (maxwell2 works, too, but it is currently a bit too messy to actually
> do it, but it works).

> Have fun.

> Karol Herbst (20):
>   clk: Fix potential NULL pointer access when there is no fb subdev
>   fb/ramgk104: Touch 0x62c000 only when there is a display engine
>   bios/volt: Handle voltage table version 0x50 with 0ed header
>   volt: Properly detect entry based voltage tables
>   clk: Don't create cstates with voltages higher than what the gpu can
>     do
>   volt: Parse the max voltage map entries
>   volt: Add min_id parameter to nvkm_volt_set_id
>   clk: Add index field to nvkm_cstate
>   clk: Let nvkm_clk_tstate take a temperature value
>   volt: Add temperature parameter to nvkm_volt_map
>   clk: Fixup cstate selection
>   clk: Respect voltage limits in nvkm_cstate_prog
>   bios: Add parsing of VPSTATE table
>   clk: Allow boosting only when NvBoost is set
>   volt: Don't require perfect fit
>   bios/vmap: unk0 field is the mode
>   volt: Add implementation for gf100
>   volt/gf100-: Add speedo
>   volt: Make use of cvb coefficients
>   fb/ram: Use Kepler implementation on Maxwell
