2017-12-19drm/omap: panel-dsi-cm: add external backlight supportSebastian Reichel1-31/+60
Droid 4 has a command mode DSI panel, which does not have/use DSI based backlight support. This adds proper support for this using a backlight phandle property, which follows the common panel binding. If no backlight phandle is found, it is assumed, that the native backlight should be used instead. This is used by the Nokia N950.

2017-12-19drm/omap: Filter displays mode based on bandwidth limitPeter Ujfalusi3-0/+45
If we have memory bandwidth limit configured, reject the modes which would require more bandwidth than the limit if it is used with one full resolution plane (most common use case). This filtering is not providing full protection as it is possible that application would pick smaller crtc resolution with high resolution planes and down scaling, or can enable more smaller planes where the sum of their bandwidth need would be higher than the limit. This patch only allows us to filter out modes which would need more bandwidth if they were used with one full screen plane.

2017-12-19drm/nouveau: avoid GPU page sizes > PAGE_SIZE for buffer objects in host memoryBen Skeggs1-1/+2
While the Tegra (GK20A, GM20B, GP10B) MMUs support large pages in host memory, we're currently lacking IOMMU support for merging system pages into large enough chunks to be mapped as such by the GPU. The core VMM code actually supports automatically determining the best page size to map with, which is intended for these situations, but for various complicated reasons the DRM is currently forcing the page size selection on a per-BO basis. This should fix breakage reported on Tegra GPUs in the meantime, until one or both of the above issues are resolved properly.

The call to drm_fb_helper_funcs.fb_probe is deferred until there is a display for real since 4.14, that's why fbcon->helper.fb is still not set.

2017-12-18drm/i915: Protect DDI port to DPLL map from theoretical race.Rodrigo Vivi1-0/+4
In case we have multiple modesets for different connectors happening in parallel we could have a race on the RMW on these shared registers. This possibility was initially raised by Paulo when reviewing commit '555e38d27317 ("drm/i915/cnl: DDI - PLL mapping")' but the original possibility comes from commit '5416d871136d ("drm/i915/skl: Set the eDP link rate on DPLL0")'. Or maybe later when atomic commits entered into picture. Apparently the discussion around this topic showed that the right solution would be on serializing the atomic commits in a way that we don't have the possibility of races here since if that parallel modeset happenings apparently many other things will be on fire. Code is there since SKL and there was no report of issue, but since we never looked back to that serialization possibility, and also we don't have an igt case for that it is better to at least protect this corner.

2017-12-18drm/i915/trace: add hw_id to gem requests trace pointsLionel Landwerlin1-14/+22
When monitoring the GPU with i915 perf, reports are tagged with a hw id. Gem context creation tracepoints already have a hw_id field, unfortunately you only get this correlation between a process id and a hw context id once when the context is created. It doesn't help if you started monitoring after the process was initialized or if the drm fd was transfered from one process to another. This change adds the hw_id field to gem requests, so that correlation can also be done on submission. v2: Place hw_id at the end of the tracepoint to not disrupt too much existing tools (Chris) v3: Reorder hw_id field again (Chris) v4: Add missing hw_id to i915_gem_request_wait_begin tracepoint (Chris) Signed-off-by: Lionel Landwerlin <[email protected]> Reviewed-by: Chris Wilson <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
