* drm/radeon: Fix PCIe lane width calculationPaul Parsons2018-04-03
| | | | | | | | | | | | | | | | | | Two years ago I tried an AMD Radeon E8860 embedded GPU with the drm driver. The dmesg output included driver warnings about an invalid PCIe lane width. Tracking the problem back led to si_set_pcie_lane_width_in_smc(). 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. Applying the increment silenced the warnings. The code has not changed since, so either my analysis was incorrect or the bug has gone unnoticed. Hence submitting this as an RFC.

| | | | | | | | | | | | | | We need more control over the ordering of dpm init with respect to the rest of the asic. Specifically, the SMC has to be initialized before the rlc and cg/pg. The pm code currently initializes late in the driver, but we need it to happen much earlier so move pm handling into the asic specific callbacks.
