<title>drm/amdgpu: Update power state at the end of smu hw_init.</title>

<id>urn:sha1:2ab4d0e74256fc49b7b270f63c1d1e47c2455abc</id>
<content type='text'>
For SI/Kv, the power state is managed by function
amdgpu_pm_compute_clocks.

when dpm enabled, we should call amdgpu_pm_compute_clocks
to update current power state instand of set boot state.

this change can fix the oops when kfd driver was enabled on Kv.

<content type='text'>
Use the newly exported pci functions to get the link width
and speed rather than using the drm duplicated versions.

Also query the GPU link caps directly rather than hardcoding
them.

1. move ac_power to struct pm from dpm, so can be shared with powerplay
2. remove power_source in powerplay, use adev-&gt;pm.ac_power instand.
3. update ac_power before dispatch power task.

<id>urn:sha1:6396bb221514d2876fd6dc0aa2a1f240d99b37bb</id>
<content type='text'>
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:

        kzalloc(a * b, gfp)

with:
        kcalloc(a * b, gfp)

as well as handling cases of:

        kzalloc(a * b * c, gfp)

with:

        kzalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kzalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kzalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

// Fix redundant parens around sizeof().

expression THING, E;

<content type='text'>
The calculation of the lane widths via ATOM_PPLIB_PCIE_LINK_WIDTH_MASK and
ATOM_PPLIB_PCIE_LINK_WIDTH_SHIFT macros did not increment the resulting
value, per the comment in pptable.h ("lanes - 1"), and per usage elsewhere.
Port of the radeon fix to amdgpu.
