drm/amdgpu: Don't default to DC support for Kaveri and older

2018-07-08T13:32:19Z

commit d9fda248046ac035f18a6e663f2f9245b4bf9470 upstream. We've had a number of users report failures to detect and light up display with DC with LVDS and VGA. These connector types are not currently supported with DC. I'd like to add support but unfortunately don't have a system with LVDS or VGA available. In order not to cause regressions we should probably fallback to the non-DC driver for ASICs that support VGA and LVDS. These ASICs are: * Bonaire * Kabini * Kaveri * Mullins ASIC support can always be force enabled with amdgpu.dc=1 v2: Keep Hawaii on DC v3: Added Mullins to the list Cc: stable@vger.kernel.org Signed-off-by: Harry Wentland Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: Fix NULL ptr on driver unload due to init failure.

2018-03-21T20:04:42Z

Problem: When unloading due to failure amdgpu_device_fini was called twice which was leading to NULL ptr in amdgpu_irq_disable_all. Fix: Call amdgpu_device_fini only once from amdgpu_driver_unload_kms. Reviewed-by: Alex Deucher Signed-off-by: Andrey Grodzovsky Signed-off-by: Alex Deucher

drm/amdgpu - Disable all irqs before disabling all CRTCs

2018-03-21T04:44:12Z

By moving amdgpu_irq_disable_all earlier in the sequence fixes an issue with disabling pflip interrupts: *ERROR* dal_irq_service_dummy_ack: called for non-implemented irq source Earlier patch fixed a memory corruption and revealed irq warnings.This way it seems to be there no obvious issues with unloading the module.
