2018-10-03drm/amdgpu: Update power state at the end of smu hw_init.Rex Zhu
[ Upstream commit 2ab4d0e74256fc49b7b270f63c1d1e47c2455abc ] 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.

2018-04-24drm/amdgpu: Fix PCIe lane width calculationAlex Deucher
commit 41212e2fe72b26ded7ed78224d9eab720c2891e2 upstream. 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.
