2017-12-16drm/i915: Restore the kernel context after a GPU reset on an idle engineChris Wilson
As part of the system requirement for powersaving is that we always have a context loaded. Upon boot and resume, we load the kernel_context to ensure that some valid state is set before powersaving kicks in, we should do so after a full GPU reset as well. We only need to do so for an idle engine, as any active engines will restart by executing the stuck request, loading its context. For the idle engine, we create a new request to load the kernel_context instead. For whatever reason, perfoming a dummy execute on the idle engine after reset papers over a subsequent GPU hang in rare circumstances, even on machines not using contexts (e.g. Pineview).

2017-12-16drm/i915: Skip an engine reset if it recovered before our preparationsChris Wilson
At the beginning of a reset, we disable the submission method and find the stuck request. We expect to find a stuck request for we have declared the engine stalled. However, if we find no active request, the engine must have recovered from its stall before we could issue a reset, so let the engine continue on without a reset. If the engine is truly stuck, we will back soon enough with the next reset attempt. v2: Remove the stale debug message.

2017-12-15drm/sun4i: validate modes for HDMIHans Verkuil
When I connected my cubieboard running 4.15-rc1 to my 4k display I got no picture. Some digging found that there is no check against the upper pixelclock limit of the HDMI output, so X selects a 4kp60 format at 594 MHz, which obviously won't work. The patch below adds a check for the upper bound of what this hardware can do, and it checks if the requested tmds clock can be obtained. It also allows for the +/- 0.5% pixel clock variation that the HDMI spec permits. That code is based on commit 22d0be2a557e ("drm: arcpgu: Allow some clock deviation in crtc->mode_valid() callback") from Jose Abreu for drm/arc.

2017-12-15drm/atomic: document how to handle driver private objectsDaniel Vetter
DK put some nice docs into the commit introducing driver private state, but in the git history alone it'll be lost. Also, since Ville remove the void* usage it's a good opportunity to give the driver private stuff some tlc on the doc front. Finally try to explain why the "let's just subclass drm_atomic_state" approach wasn't the greatest, and annotate all those functions as deprecated in favour of more standardized driver private states. Also note where we could/should extend driver private states going forward (atm neither locking nor synchronization is handled in core/helpers, which isn't really all that great). v2: Spelling and phrasing improvements (Alex, DK).
