2016-03-14drm/nouveau/clk/gk20a: only compute n_lo if neededAlexandre Courbot1-3/+5
n_lo is used if we are going to slide. Compute it only if that condition succeeds to avoid confusion about future usage of this computation. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/clk/gk20a: fix VCO bit maskAlexandre Courbot1-1/+2
Fix the mask specified to switch to VCO mode was given as an (incorrect) immediate value. Although the side-effect happens to be the same, this is clearly incorrect. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/clk/gk20a: rename enable/disable functionsAlexandre Courbot1-28/+24
gk20a_pllg_disable() is only used in the context of gk20a_clk_fini(). Move its body there and rename _gk20a_pllg_enable() and _gk20a_pllg_disable() to non-underscored versions. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/clk/gk20a: reorganize variables in gk20a_pllg_calc_mnp()Alexandre Courbot1-4/+8
Move some variables declarations to the scope where they are actually used to make the code easier to follow. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2015-08-28drm/nouveau/device: include core/device.h automatically for subdevs/enginesBen Skeggs8-9/+0
Pretty much every subdev/engine is going to need access to nvkm_device shortly to touch registers and/or output messages. The odd placement of the includes is necessary to work around some inter-dependencies that currently exist. This will be fixed later. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-08-28drm/nouveau/drm/nouveau/clk: fix tstate to pstate calculationWei Ni1-1/+1
According to the tstate calculation in nvkm_clk_tstate(), the range of tstate is from -(clk->state_nr - 1) to 0, it mean the tstate is negative value. But in nvkm_pstate_work(), it use (clk->state_nr - 1 - clk->tstate) to limit pstate, it's not correct. This patch fix it to use (clk->state_nr - 1 + clk->tstate) to limit pstate.

2015-04-14make RAM device optionalAlexandre Courbot1-1/+1
Having a RAM device does not make sense for chips like GK20A which have no dedicated video memory. The dummy RAM device that we used so far works as a temporary band-aid, but in the longer term it is desirable for the driver to be able to work without any kind of VRAM. This patch adds a few conditionals in places where a RAM device was assumed to be present and allows some more objects to be allocated from the TT domain, allowing Nouveau to handle GPUs for which pfb->ram == NULL.

2015-01-22drm/nouveau/volt: namespace + nvidia gpu names (no binary change)Ben Skeggs1-0/+1
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>

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.
