[PATCH] pci/g92: Fix rearm
704a6c008b7942bb7f30bb43d2a6bcad7f543662 broke pci msi rearm for g92 GPUs.
g92 needs the nv46_pci_msi_rearm, where g94+ gpus used nv40_pci_msi_rearm.

[PATCH v4 0/9] PCIe speed changes
overall it is for the most part the same as my older version.
I cleaned up some copyright things, so that it is more like the others.
Also I moved the print about the max speed supported into preinit and did
some other minor cleanups in the 3rd commit.
Happy testing (and performance for prime offloading setups)

[PATCH] drm/nouveau: Add support for clockgating on Fermi+
This adds support for enabling automatic clockgating on nvidia GPUs for
Fermi and later generations. This saves a little bit of power, bringing
my fermi GPU's power consumption from ~28.3W on idle to ~27W, and my
kepler's idle power consumption from ~23.6W to ~21.65W.
Similar to how the nvidia driver seems to handle this, we enable
clockgating for each engine that supports it after

[RFC v2 0/4] Implement full clockgating for Kepler1 and 2
Next version of my patchseries for adding clockgating support for
kepler1 and 2 on nouveau. The first version of this series can be found
here:
https://patchwork.freedesktop.org/series/36504/
Some minor changes:
- Clarified that SLCG stands for 'secondary level clockgating', thanks
for the small tip nvidia!
- Removed the concept of levels, this was more useful for debugging

[RFC 0/4] Implement full clockgating for Kepler1 and 2
It's here! After a lot of investigation, rewrites, and traces, I present
the patch series to implement all known levels of clockgating for
Kepler1 and Kepler2 GPUs.
Starting with Fermi GPUs (this is probably present on earlier GPUs as
well, but with a far less easy to manage interface), nvidia added two
clockgating levels that are handled mostly in firmware (with the
exception of course, of

[PATCH] therm: debug print the FSRM config on [nvc0, nvf0) cards
before we can let nouveau fully reclock the gpu automatically, we should have
a fail safe mechanism to prevent the card from overheating.
Starting with G84 GPUs the so called FSRM does the job and automatically
downclocks the GPU when specific temperatures thresholds are hit. Lucky for us
the needed bits are already configured through a script inside the vbios at
POST time and we only need to

[PATCH v5 00/20] Engine Reclocking Fixes for Fermi-Maxwell2
I've splitted my big series between the part which actually fixes the
engine reclocking bits and the part handling voltage/clock updates on
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

[PATCH v4 00/37] Volting/Clocking improvements for Fermi and newer
We are slowly getting there!
v4 of the series with some realy good improvements, so I am sure this is like
95% done and only needs some proper polishing and proper Reviews!
I also added the NvVoltOffsetmV module parameter, so that a user is able to
over and !under!-volt the GPU. Overvolting makes sense, when there are still
some reclocking issues left, which might be solved by a higher voltage.

[RFC v2 1/4] drm/nouveau: Add support for basic clockgating on Kepler1
This adds support for enabling automatic clockgating on nvidia GPUs for
Kepler1. While this is not technically a clockgating level, it does
enable clockgating using the clockgating values initially set by the
vbios (which should be safe to use).
This introduces two therm helpers for controlling basic clockgating:
nvkm_therm_clkgate_enable() - enables clockgating through
CG_CTRL, done after
