2018-02-28drm/i915: Enable VBT based BL control for DPMustamin B Mustaffa
Currently, BXT_PP is hardcoded with value '0'. It practically disabled eDP backlight on MRB (BXT) platform. This patch will tell which BXT_PP registers (there are two set of PP_CONTROL in the spec) to be used as defined in VBT (Video Bios Timing table) and this will enabled eDP backlight controller on MRB (BXT) platform. v2: - Remove unnecessary information in commit message. - Assign vbt.backlight.controller to a backlight_controller variable and return the variable value. v3: - Rebased to latest code base. - updated commit title.

2018-02-27drm/i915/guc: Fill preempt context once at init timeMichał Winiarski
Since we're inhibiting context save of preempt context, we're no longer tracking the position of HEAD/TAIL. With GuC, we're adding a new breadcrumb for each preemption, which means that the HW will do more and more breadcrumb writes. Eventually the ring is filled, and we're submitting the preemption context with HEAD==TAIL==0, which won't result in breadcrumb write, but will trigger hangcheck instead. Instead of writing a new preempt breadcrumb for each preemption, let's just fill the ring once at init time (which also saves a couple of instructions in the tasklet). v2: Assert that context save restore is inhibited, don't assert on ring alignment.

2018-02-23drm/i915/preemption: Allow preemption between submission portsChris Wilson
Sometimes we need to boost the priority of an in-flight request, which may lead to the situation where the second submission port then contains a higher priority context than the first and so we need to inject a preemption event. To do so we must always check inside execlists_dequeue() whether there is a priority inversion between the ports themselves as well as the head of the priority sorted queue, and we cannot just skip dequeuing if the queue is empty. As Michał noted, this doesn't simply extend to handling more than 2-port submission, as we may need to reorder within the array of executing requests which themselves are lower priority than the first.

Some panels support limited range output (16-235) compared to full range RGB values (0-255). Also userspace can control the RGB range using "Broadcast RGB" property. Currently the code to handle full range to limited range is broken. This patch fixes the same by properly scaling down all the full range co-efficients with limited range scaling factor. v2: Fixed Ville's review comments. v3: Changed input to const and used correct data types as suggested by Ville v4: Fixed some missing data type corrections.

2018-02-22drm/i915/hsw: add missing disabled EUs registers readsLionel Landwerlin
It turns out that HSW has a register that tells us how many EUs are disabled per half-slice (roughly a similar notion to subslice). We didn't read those registers so far as most userspace drivers didn't need those values prior to Gen8, but an internal library would like to have access to this. Since we already have the getparam interface, there is no harm in exposing this. v2: Rename bits value (Joonas) v3: s/GEM_BUG_ON/MISSING_CASE/ (Joonas) v4: s/GEM_BUG_ON/MISSING_CASE/ again...

2018-02-21drm/i915: Rename drm_i915_gem_request to i915_requestChris Wilson
We want to de-emphasize the link between the request (dependency, execution and fence tracking) from GEM and so rename the struct from drm_i915_gem_request to i915_request. That is we may implement the GEM user interface on top of requests, but they are an abstraction for tracking execution rather than an implementation detail of GEM. (Since they are not tied to HW, we keep the i915 prefix as opposed to intel.) In short, the spatch: @@ @@ - struct drm_i915_gem_request + struct i915_request A corollary to contracting the type name, we also harmonise on using 'rq' shorthand for local variables where space if of the essence and repetition makes 'request' unwieldy. For globals and struct members, 'request' is still much preferred for its clarity.
