2018-02-26radeon: hide pointless #warning when compile testingArnd Bergmann1-1/+2
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.

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.

2018-02-26drm/pl111: Remove reverse dependency on DRM_DUMB_VGA_DACThierry Reding1-1/+0
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 Wilson4-78/+112
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.

2018-02-23drm/nouveau: prefer XBGR2101010 for addfb ioctlIlia Mirkin2-0/+5
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.)
