2018-02-26drm/radeon: insist on 32-bit DMA for Cedar on PPC64/PPC64LEBen Crocker
In radeon_device_init, set the need_dma32 flag for Cedar chips (e.g. FirePro 2270). This fixes, or at least works around, a bug on PowerPC exposed by last year's commits 8e3f1b1d8255105f31556aacf8aeb6071b00d469 (Russell Currey) and 253fd51e2f533552ae35a0c661705da6c4842c1b (Alistair Popple) which enabled the 64-bit DMA iommu bypass. This caused the device to freeze, in some cases unrecoverably, and is the subject of several bug reports internal to Red Hat.

2018-02-26radeon: hide pointless #warning when compile testingArnd Bergmann
In randconfig testing, we sometimes get this warning: drivers/gpu/drm/radeon/radeon_object.c: In function 'radeon_bo_create': drivers/gpu/drm/radeon/radeon_object.c:242:2: error: #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance thanks to write-combining [-Werror=cpp] #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance \ This is rather annoying since almost all other code produces no build-time output unless we have found a real bug. We already fixed this in the amdgpu driver in commit 31bb90f1cd08 ("drm/amdgpu: shut up #warning for compile testing") by adding a CONFIG_COMPILE_TEST check last year and agreed to do the same here, but both Michel and I then forgot about it until I came across the issue again now.

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.

2018-02-22drm/i915: Only pin the fence for primary planes (and gen2/3)Ville Syrjälä
Currently we pin a fence on every plane doing tiled scanout. The number of planes we have available is fast apporaching the number of fences so we really should stop wasting them. Only FBC needs the fence on gen4+, so let's use fences only for the primary planes on those platforms. v2: drop the tiling check from plane_uses_fence() as the obj is NULL during initial_plane_config() and we don't rally need the check since i915_vma_pin_fence() does the check anyway Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180221184807.577-1-ville.syrjala@linux.intel.com Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
2018-02-22drm/i915: Fail if we can't get a fence for gen2/3 tiled scanoutVille Syrjälä
Gen2/3 display engine depends on the fence for tiled scanout. So if we fail to get a fence fail the entire operation.

2018-02-22drm/i915: Fix Limited Range Color HandlingJohnson Lin
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/sun4i: Remove the plane description structureMaxime Ripard
The plane description structure was mostly needed to differentiate the formats usable on the primary plane (because of its lowest position), and assign the pipes. Now that both are dynamically checked and assigned, we can remove the static definition.

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...
