2016-12-07drm/amd/amdgpu: enable GUI idle INT after enabling CGCGArindam Nath1-9/+9
GUI idle interrupts should be enabled only after we have enabled coarse grain clock gating (CGCG). This prevents GFX engine generating idle interrupt even though CGCG is not completely enabled. Most of the time this goes un-noticed, but on some Stoney ASICs this results in GFX engine hang after system resumes from suspend. The issue is not particular to Stoney though and could have occured on any ASIC. The patch fixes this issue.

Since commit 8a357d10043c ("drm: Nerf DRM_CONTROL nodes"), a struct drm_device's ->control member is always NULL. In the case of CONFIG_DEBUG_FS=y, amdgpu_debugfs_add_files() accesses ->control->debugfs_root though. This results in a NULL pointer dereference.

2016-11-23drm/amdgpu: fix power state when port pm is unavailablePeter Wu1-1/+8
When PCIe port PM is not enabled (system BIOS is pre-2015 or the pcie_port_pm=off parameter is set), legacy ATPX PM should still be marked as supported. Otherwise the GPU can fail to power on after runtime suspend. This affected a Dell Inspiron 5548. Ideally the BIOS date in the PCI core is lowered to 2013 (the first year where hybrid graphics platforms using power resources was introduced), but that seems more risky at this point and would not solve the pcie_port_pm=off issue.
