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:

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:

The CVB calculation and voltage setting functions can be reused for the future chips. So move the declaration to gk20a.h. Signed-off-by:

This class supports a WFI method (0x0078) that's not present on the KeplerChannelGpfifoA class. The binary driver exposes both classes on these GPUs for some reason, though there doesn't appear to be any difference in the setup that's done for each (ie. even if you allocate GpfifoA, the WFI method will still work). We shall just expose GpfifoB, as I don't see a good reason to report the presence of both. Signed-off-by: -

It's supposed to always be 0, but at least nv_iowr() temporarily violates this. Since the ih touches $r0, it should be stored. Signed-off-by:

Most calls to nvkm_ramht_new use 0x8000 as the size. This results in a fairly sizeable chunk of memory to be allocated, which may not be available with kzalloc. Since this is done fairly rarely (once per channel), use vzalloc instead. Signed-off-by:

A channel may still be processed by the PBDMA even after removal, unless it is properly kicked. Some chips are more sensible to this than others, with GM20B triggering the issue very easily (the PBDMA will try to fetch methods from the previously-removed channel after a new one is added). Make sure this cannot happen by kicking the channel right after it is disabled, and before the new runlist is submitted. Signed-off-by:
