      drm/nouveau: Add support for basic clockgating on Kepler1 · b138eca6
      由 Lyude Paul 提交于 
      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 initializing the GPU fully
	nvkm_therm_clkgate_fini() - prepares clockgating for suspend or
	driver unload

A lot of this code was originally going to be based off of fermi;
however it turns out that while Fermi's the first line of GPUs that
introduced this kind of power saving, Fermi requires more fine tuned
control of the CG_CTRL registers from the driver while reclocking that
we don't entirely understand yet.

For the simple parts we will be sharing with Fermi for certain however,
we at least add those into a new subdev/therm/gf100.h header.

      drm/nouveau/therm: namespace + nvidia gpu names (no binary change) · e1404611
      由 Ben Skeggs 提交于 
      The namespace of NVKM is being changed to nvkm_ instead of nouveau_,
which will be used for the DRM part of the driver.  This is being
done in order to make it very clear as to what part of the driver a
given symbol belongs to, and as a minor step towards splitting the
DRM driver out to be able to stand on its own (for virt).

Because there's already a large amount of churn here anyway, this is
as good a time as any to also switch to NVIDIA's device and chipset
naming to ease collaboration with them.

A comparison of objdump disassemblies proves no code changes.

      drm/nouveau: remove symlinks, move core/ to nvkm/ (no code changes) · c39f472e
      由 Ben Skeggs 提交于 
      The symlinks were annoying some people, and they're not used anywhere
else in the kernel tree.  The include directory structure has been
changed so that symlinks aren't needed anymore.

NVKM has been moved from core/ to nvkm/ to make it more obvious as to
what the directory is for, and as some minor prep for when NVKM gets
split out into its own module (virt) at a later date.
