2018-02-26drm/sun4i: Enable the output on the pins (tcon0)Ondrej Jirman
I noticed that with 4.16-rc1 LVDS output on A83T based TBS A711 tablet doesn't work (there's output but it's garbled). I compared some older patches for LVDS support with the mainlined ones and this change is missing from mainline Linux. I don't know what the register does exactly and the harcoded register value doesn't inspire much confidence that it will work in a general case, so I'm sending this RFC. This patch fixes the issue on A83T.

2018-02-26drm/pl111: Remove reverse dependency on DRM_DUMB_VGA_DACThierry Reding
DRM_DUMB_VGA_DAC is a user-visible symbol. Selecting it can cause unmet direct dependencies such as this (on i386, randconfig): warning: (DRM_PL111) selects DRM_DUMB_VGA_DAC which has unmet direct dependencies (HAS_IOMEM && DRM && DRM_BRIDGE && OF) This is because DRM_DUMB_VGA_DAC depends on OF while DRM_PL111 does not. It does indirectly depend on OF via the ARM and ARM64 dependencies, but since it can also be enabled under COMPILE_TEST, randconfig can find a case where DRM_PL111 is selected without pulling in OF and not meeting the dependency for DRM_DUMB_VGA_DAC. Since select is "heavy handed", DRM_DUMB_VGA_DAC is going to be enabled regardless of the above warning and causes the following build error: ../drivers/gpu/drm/bridge/dumb-vga-dac.c: In function 'dumb_vga_probe': ../drivers/gpu/drm/bridge/dumb-vga-dac.c:207:13: error: 'struct drm_bridge' has no member named 'of_node' vga->bridge.of_node = pdev->dev.of_node; See Documentation/kbuild/kconfig-language.txt, "reverse dependencies".

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. A task for later!

2018-02-23drm/nouveau: prefer XBGR2101010 for addfb ioctlIlia Mirkin
Nouveau only exposes support for XBGR2101010. Prior to the atomic conversion, drm would pass in the wrong format in the framebuffer, but it was always ignored -- both userspace (xf86-video-nouveau) and the kernel driver agreed on the layout, so the fact that the format was wrong didn't matter. With the atomic conversion, nouveau all of a sudden started caring about the exact format, and so the previously-working code in xf86-video-nouveau no longer functioned since the (internally-assigned) format from the addfb ioctl was wrong. This change adds infrastructure to allow a drm driver to specify that it prefers the XBGR format variant for the addfb ioctl, and makes nouveau's nv50 display driver set it. (Prior gens had no support for 30bpp at all.)

2018-02-22drm/sun4i: backend: Assign the pipes automaticallyMaxime Ripard
Since we now have a way to enforce the zpos, check for the number of alpha planes, the only missing part is to assign our pipe automatically instead of hardcoding it. The algorithm is quite simple, but requires two iterations over the list of planes. In the first one (which is the same one that we've had to check for alpha, the frontend usage, and so on), we order the planes by their zpos. We can then do a second iteration over that array by ascending zpos starting with the pipe 0. When and if we encounter our alpha plane, we put it and all the other subsequent planes in the second pipe.

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.
