drm/radeon: Fix eDP for single-display iMac10,1 (v2)

2017-10-12T14:28:03+00:00

commit 564d8a2cf3abf16575af48bdc3e86e92ee8a617d upstream. The late 2009, 27 inch Apple iMac10,1 has an internal eDP display and an external Mini- Displayport output, driven by a DCE-3.2, RV730 Radeon Mobility HD-4670. The machine worked fine in a dual-display setup with eDP panel + externally connected HDMI or DVI-D digital display sink, connected via MiniDP to DVI or HDMI adapter. However, booting the machine single-display with only eDP panel results in a completely black display - even backlight powering off, as soon as the radeon modesetting driver loads. This patch fixes the single dispay eDP case by assigning encoders based on dig->linkb, similar to DCE-4+. While this should not be generally necessary (Alex: "...atom on normal boards should be able to handle any mapping."), Apple seems to use some special routing here. One remaining problem not solved by this patch is that an external Minidisplayport->DP sink does still not work on iMac10,1, whereas external DVI and HDMI sinks continue to work. The problem affects at least all tested kernels since Linux 3.13 - didn't test earlier kernels, so backporting to stable probably makes sense. v2: With the original patch from 2016, Alex was worried it will break other DCE3.2 systems. Use dmi_match() to apply this special encoder assignment only for the Apple iMac 10,1 from late 2009.

drm/radeon: Unbreak HPD handling for r600+

2017-09-15T17:29:51+00:00

commit 3d18e33735a02b1a90aecf14410bf3edbfd4d3dc upstream. We end up reading the interrupt register for HPD5, and then writing it to HPD6 which on systems without anything using HPD5 results in permanently disabling hotplug on one of the display outputs after the first time we acknowledge a hotplug interrupt from the GPU. This code is really bad. But for now, let's just fix this. I will hopefully have a large patch series to refactor all of this soon.

drm/radeon: Use mode h/vdisplay fields to hide out of bounds HW cursor

commit d74c67dd7800fc7aae381f272875c337f268806c upstream. The crtc_h/vdisplay fields may not match the CRTC viewport dimensions with special modes such as interlaced ones. Fixes the HW cursor disappearing in the bottom half of the screen with interlaced modes.
