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.

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.)

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.

The plane buffer address/stride/height was incorrectly updated in the plane_atomic_update operation instead of the vsync irq. This patch delays this operation in the vsync irq along with the other plane delayed setup. This issue was masked using legacy framebuffer and X11 modesetting, but is clearly visible using gbm rendering when buffer is submitted late after vblank, like using software decoding and OpenGL rendering in Kodi.

Bit field [2:0] of HDMI_I2S_PIN_SEL_1 corresponds to SDATA_0, not SDATA_2. This patch removes redefinition of HDMI_I2S_SEL_DATA2 constant and adds missing HDMI_I2S_SEL_DATA0.

2018-02-20drm/exynos: g2d: use monotonic timestampsArnd Bergmann1-3/+3
The exynos DRM driver uses real-time 'struct timeval' values for exporting its timestamps to user space. This has multiple problems: 1. signed seconds overflow in y2038 2. the 'struct timeval' definition is deprecated in the kernel 3. time may jump or go backwards after a 'settimeofday()' syscall 4. other DRM timestamps are in CLOCK_MONOTONIC domain, so they can't be compared 5. exporting microseconds requires a division by 1000, which may be slow on some architectures. The code existed in two places before, but the IPP portion was removed in 8ded59413ccc ("drm/exynos: ipp: Remove Exynos DRM IPP subsystem"), so we no longer need to worry about it. Ideally timestamps should just use 64-bit nanoseconds instead, but of course we can't change that now. Instead, this tries to address the first four points above by using monotonic 'timespec' values. According to Tobias Jakobi, user space doesn't care about the timestamp at the moment, so we can change the format. Even if there is something looking at them, it will work just fine with monotonic times as long as the application only looks at the relative values between two events.

2018-02-17drm: Allow determining if current task is output poll workerLukas Wunner1-0/+20
Introduce a helper to determine if the current task is an output poll worker. This allows us to fix a long-standing deadlock in several DRM drivers wherein the ->runtime_suspend callback waits for the output poll worker to finish and the worker in turn calls a ->detect callback which waits for runtime suspend to finish. The ->detect callback is invoked from multiple call sites and waiting for runtime suspend to finish is the correct thing to do except if it's executing in the context of the worker. v2: Expand kerneldoc to specifically mention deadlock between output poll worker and autosuspend worker as use case.
