2018-09-09drm: Add drm/drm_util.h header fileDaniel Vetter
We have a bunch of neat little macros all over the place which should move to kernel.h. But some of them died in bikesheds on lkml, and we need a decent home for them. Start out by moving the for_each_if macro there. v2: Rename to drm_util.h instead (Dave&Sean) Cc: Sean Paul <seanpaul@chromium.org> Acked-by: Sean Paul <seanpaul@chromium.org> Cc: Dave Airlie <airlied@gmail.com> Acked-by: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20180905135711.28370-1-daniel.vetter@ffwll.ch

2018-09-07drm/sun4i: tcon: Add dithering support for RGB565/RGB666 LCD panelsJonathan Liu
The hardware supports dithering on TCON channel 0 which is used for LCD panels. Dithering is a method of approximating a color from a mixture of other colors when the required color isn't available. It reduces color banding artifacts that can be observed when displaying gradients (e.g. grayscale gradients). This may occur when the image that needs to be displayed is 24-bit but the LCD panel is a lower bit depth and does not perform dithering on its own.

2018-09-07drm/sun4i: tcon: Pass drm_encoder * into sun4i_tcon0_mode_set_cpuChen-Yu Tsai
sun4i_tcon0_mode_set_cpu() currently accepts struct mipi_dsi_device * as its second parameter. This is derived from drm_encoder. The DSI encoder is tied to the CPU interface mode of the TCON as a special case. In theory, if hardware were available, we could also support normal CPU interface modes. It is better to pass the generic encoder instead of the specialized mipi_dsi_device, and handle the differences inside the function. Passing the encoder would also enable the function to pass it, or any other data structures related to it, to other functions expecting it. One such example would be dithering support that will be added in a later patch, which looks at properties tied to the connector to determine whether dithering should be enabled or not.

2018-09-06drm: fix drm_mode_addfb() on big endian machines.Gerd Hoffmann
Userspace on big endian machhines typically expects the ADDFB ioctl returns a big endian framebuffer. drm_mode_addfb() will call drm_mode_addfb2() unconditionally with little endian DRM_FORMAT_* values though, which is wrong. This patch fixes that. Drivers (both kernel and xorg) have quirks in place to deal with the broken drm_mode_addfb() behavior. Because of this we can't just change drm_mode_addfb() behavior for everybody without breaking things. Add the quirk_addfb_prefer_host_byte_order field to mode_config, so drivers can opt-in.

2018-09-03Add udmabuf misc deviceGerd Hoffmann
A driver to let userspace turn memfd regions into dma-bufs. Use case: Allows qemu create dmabufs for the vga framebuffer or virtio-gpu ressources. Then they can be passed around to display those guest things on the host. To spice client for classic full framebuffer display, and hopefully some day to wayland server for seamless guest window display. qemu test branch: https://git.kraxel.org/cgit/qemu/log/?h=sirius/udmabuf Cc: David Airlie <airlied@linux.ie> Cc: Tomeu Vizoso <tomeu.vizoso@collabora.com> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20180827093444.23623-1-kraxel@redhat.com
