* clk: Allow boosting only when NvBoost is setKarol Herbst2016-11-041-1/+8
| | | | | | | | | | | | | | 0: base clock from the vbios is max clock (default) 1: boost only to boost clock from the vbios 2: boost to max clock available v2: Moved into nvkm_cstate_valid. v4: Check the existence of the clocks before limiting. v5: Default to boost level 0.

* clk: Fixup cstate selectionKarol Herbst2016-11-041-0/+4
| | | | | | | | | | | | Now the cstatei parameter can be used of the nvkm_cstate_prog function to select a specific cstate. v5: Make a constant for the magic value. Use list_last_entry. Add nvkm_cstate_get here instead of in the next commit. Signed-off-by: Karol Herbst <karolherbst@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* clk: Let nvkm_clk_tstate take a temperature valueKarol Herbst2016-11-041-2/+2
| | | | | | | | | | This way other subdevs can notify the clk subdev about temperature changes without the need of clk to poll that value. Also make this function safe to be called from an interrupt handler. Signed-off-by: Karol Herbst <karolherbst@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* clk: Add index field to nvkm_cstateKarol Herbst2016-11-041-0/+1
| | | | | | | | | | | It is better to read out the id out of the cstate struct directly instead of iterating over the list of cstates over and over again. Especially when we start saving pointers to a nvkm_cstate struct, it makes things easier. v5: Rename field to id.

* clk: namespace + nvidia gpu names (no binary change)Ben Skeggs2015-01-191-76/+70
| | | | | | | | | | | | | | | | 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. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* clk: rename from clock (no binary change)Ben Skeggs2015-01-191-0/+166
Rename to match the Linux subsystem responsible for the same kind of things. Will be investigating how feasible it will be to expose the GPU clock trees with it at some point.
