2018-11-27drm/sun4i: frontend: Add a helper and a list for supported formatsPaul Kocialkowski
In order to check whether the frontend supports a specific format, an explicit list and a related helper are introduced. Just like in the backend, the prototype of the helper is added to the frontend header so that it can be used later on. The helper is also exported because it will be used outside of the frontend module.

2018-11-27drm/sun4i: Add TODO comment about supporting scaling with the backendPaul Kocialkowski
The backend allows integer-only scaling but can handle alpha components, unlike the frontend. It could be useful to add support for this eventually, so add a short TODO comment describing the situation.

2018-11-27drm/sun4i: frontend: Replace ARGB with XRGB as supported formatPaul Kocialkowski
The frontend documentation (for the A33) mentions that ARGB is supported as output, but with the alpha component always set to 0xff. In practice, this means that the alpha component cannot be preserved when going through the frontend. Since the information is lost, ARGB is not properly supported. As a result, expose the matching format supported by the frontend (both for input and output) as XRGB instead of ARGB. Since ARGB was the selected format for connecting the frontend to the backend, change it to XRGB to reflect this as well. The A31 and A80 SoCs apparently have a bit to enable proper alpha, but this is not supported at this point (see the comment already in the code).

2018-11-27drm/sun4i: Cleanup video/YUV source before enabling a layerPaul Kocialkowski
This adds a dedicated function for cleaning the video and YUV source channel layer enable bits. This function is called first on layer atomic update to make sure that there are no leftover bits from previous plane configuration that were not cleaned until now. It fixes issues when alternating between video and YUV planes, where both bits would be set eventually, leading to broken plane display.

2018-11-23drm/atomic-helper: Complete fake_commit->flip_done potentially earlierVille Syrjälä
Consider the following scenario: 1. nonblocking enable crtc 2. wait for the event 3. nonblocking disable crtc On i915 this can lead to a spurious -EBUSY from step 3 on account of non-enabled planes getting the fake_commit in step 1 and we don't complete the fake_commit-> flip_done until drm_atomic_helper_commit_hw_done() which can happen a long time after the flip event was sent out. This will become somewhat easy to hit on SKL+ once we start to add all the planes for the crtc to every modeset commit for the purposes of forcing a watermark register programming [1]. To make the race a little less pronounced let's complete fake_commit->flip_done after drm_atomic_helper_wait_for_flip_done(). For the single crtc case this should make the race quite theoretical, assuming drm_atomic_helper_wait_for_flip_done() actually has to wait for the real commit flip_done. In case the real commit flip_done gets completed singificantly before drm_atomic_helper_wait_for_flip_done(), or we are dealing with multiple crtcs whose vblanks don't line up nicely the race still exists.

2018-11-21qxl: Make sure qxl_cursor memory is pinnedChristophe Fergeau
QEMU keeps a vram reference to the last QXLCursorCmd it received. This QXLCursorCmd command points to a QXLCursor instance (stored in vram too). However, while the QXLCursorCmd memory is pinned, the QXLCursor memory is not. When booting a recent Fedora to its login screen while monitoring the QXLCursorCmd QEMU holds, it's possible to see the QXLCursor memory becoming invalid shortly after boot. Pinning that memory ensures that that QXLCursor memory is not going to be moved by the guest kernel. Moving the pin/unpin to qxl_release_list_add()/qxl_release_free_list() would be a more generic fix. However, doing this quickly exhausts QXL video memory, so more fixing would be needed before this is workable.

2018-11-19drm/rockchip: fix for mailbox read sizeDamian Kos
Some of the functions (like cdn_dp_dpcd_read, cdn_dp_get_edid_block) allow to read 64KiB, but the cdn_dp_mailbox_read_receive, that is used by them, can read only up to 255 bytes at once. Normally, it's not a big issue as DPCD or EDID reads won't (hopefully) exceed that value. The real issue here is the revocation list read during the HDCP authentication process. (problematic use case: https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4/drivers/gpu/drm/rockchip/cdn-dp-reg.c#1152) The list can reach 127*5+4 bytes (num devs * 5 bytes per ID/Bksv + 4 bytes of an additional info). In other words - CTSes with HDCP Repeater won't pass without this fix. Oh, and the driver will most likely stop working (best case scenario).

2018-11-15drm/bridge/sii902x: Fix EDID readbackFabrizio Castro
While adding SiI9022A support to the iwg23s board, it came up that when the HDMI transmitter is in pass through mode the device is not compliant with the I2C specification anymore, as it requires a far bigger tbuf, due to a delay the HDMI transmitter is adding when relaying the STOP condition on the monitor i2c side of things. When not providing an appropriate delay after the STOP condition the i2c bus would get stuck. Also, any other traffic on the bus while talking to the monitor may cause the transaction to fail or even cause issues with the i2c bus as well. I2c-gates seemed to reach consent as a possible way to address these issues, and as such this patch is implementing a solution based on that. Since others are clearly relying on the current implementation of the driver, this patch won't require any DT changes. Since we don't want any interference during the DDC Bus Request/Grant procedure and while talking to the monitor, we have to use the adapter locking primitives rather than the i2c-mux locking primitives.

2018-11-15drm/panel: Augment the TPO TPG110 bindingsLinus Walleij
The TPO TPG110 bindings were using the DPI bindings (popular in the fbdev subsystem) but this misses the finer points learned in the DRM subsystem. We need to augment the bindings for proper DRM integration: the timings are expressed by the hardware, not put into the device tree. I.e. this hardware is self-describing and can report the resolutions and timings needed. It should not be described in the device tree. Further the device was incorrectly modeled with GPIO lines instead of an SPI child, even though the device was using SPI. No known deployments of the device using device tree exist, so it should be fine to augment the bindings.

2018-11-14drm/virtio: add in/out fence support for explicit synchronizationRobert Foss
When the execbuf call receives an in-fence it will get the dma_fence related to that fence fd and wait on it before submitting the draw call. On the out-fence side we get fence returned by the submitted draw call and attach it to a sync_file and send the sync_file fd to userspace. On error -1 is returned to userspace. VIRTGPU_EXECBUF_FENCE_FD_IN & VIRTGPU_EXECBUF_FENCE_FD_OUT are supported at the simultaneously and can be flagged for simultaneously.

2018-11-14drm/virtio: add uapi for in and out explicit fencesRobert Foss
Add a new field called fence_fd that will be used by userspace to send in-fences to the kernel and receive out-fences created by the kernel. This uapi enables virtio to take advantage of explicit synchronization of dma-bufs. There are two new flags: * VIRTGPU_EXECBUF_FENCE_FD_IN to be used when passing an in-fence fd. * VIRTGPU_EXECBUF_FENCE_FD_OUT to be used when requesting an out-fence fd The execbuffer IOCTL is now read-write to allow the userspace to read the out-fence. On error -1 should be returned in the fence_fd field.

2018-11-13drm/meson: Add primary plane scalingNeil Armstrong
This patch adds support for the Primary Plane scaling. On the Amlogic GX SoCs, the primary plane is used as On-Screen-Display layer on top of video, and it's needed to keep the OSD layer to a lower size as the physical display size to : - lower the memory bandwidth - lower the OSD rendering - lower the memory usage This use-case is used when setting the display mode to 3840x2160 and the OSD layer is rendered using the GPU. In this case, the GXBB & GXL cannot work on more than 2000x2000 buffer, thus needing the OSD layer to be kept at 1920x1080 and upscaled to 3840x2160 in hardware. The primary plane atomic check still allow 1:1 scaling, allowing native 3840x2160 if needed by user-space applications.

2018-11-13drm/meson: Support Overlay plane for video renderingNeil Armstrong
The Amlogic Meson GX SoCs support an Overlay plane behind the primary plane for video rendering. This Overlay plane support various YUV layouts : - YUYV - NV12 / NV21 - YUV444 / 422 / 420 / 411 / 410 The scaler supports a wide range of scaling ratios, but for simplicity, plane atomic check limits the scaling from x5 to /5 in vertical and horizontal scaling. The z-order is fixed and always behind the primary plane and cannot be changed. The scaling parameter algorithm was taken from the Amlogic vendor kernel code and rewritten to match the atomic universal plane requirements. The video rendering using this overlay plane support has been tested using the new Kodi DRM-KMS Prime rendering path along the in-review V4L2 Mem2Mem Hardware Video Decoder up to 3840x2160 NV12 frames on various display modes.
