drm/amdgpu: Fix PCIe lane width calculation

2018-04-03T18:08:46Z

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. Acked-by: Christian König Acked-by: Chunming Zhou Bug: https://bugs.freedesktop.org/show_bug.cgi?id=102553 Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/amd/powerplay: Followup fixes to mc_reg_address

2017-12-06T17:48:00Z

This is a followup to: drm/amd/powerplay: Fix buffer overflows with mc_reg_address Rework *_set_mc_special_registers for the other architectures to use the same logic as the first patch. This allows the last entry of the array to be filled without an error message for example. This doesn't fix any known problems, perhaps avoided by luck.
