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. Signed-off-by:

Dithering is only supported for TCON channel 0. Throughout the datasheet all the names associated with these register are prefixed "TCON0", instead of "TCON". The only exception is the control register "TCON_FRM_CTL_REG". Rename the macros to reflect this. Signed-off-by:

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.

Since this is handling user provided bpp and depth, we need to sanity check and propagate the EINVAL back rather than assume what the insane client intended and fill the logs with DRM_ERROR. v2: Check both bpp and depth match the builtin pixel format, and introduce a canonical DRM_FORMAT_INVALID to reserve 0 against any future fourcc. v3: Mark up DRM_FORMAT_C8 as being {bpp:8, depth:8} Testcase: igt/kms_addfb_basic/legacy-format Signed-off-by:Chris Wilson <chris@chris-wilson.co.uk> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Michel Dänzer <michel.daenzer@amd.com> Reviewed-by:

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.

framebuffer_check() expects that drm_get_format_info() will not fail if the __drm_format_info() call was successful. That'll work only in case both are called with the same pixel_format value, so masking out the DRM_FORMAT_BIG_ENDIAN flag isn't a good idea. Signed-off-by:

crtc_state is accessed by both vblank_handle() and the ordered work_struct handle vkms_crc_work_handle() to retrieve and or update the frame number for computed CRC. Since work_struct can fail, add frame_end to account for missing frame numbers. Use (frame_[start/end]) for synchronization between hrtimer callback and ordered work_struct handle. This patch passes the following subtests from igt kms_pipe_crc_basic test: bad-source, read-crc-pipe-A, read-crc-pipe-A-frame-sequence, nonblocking-crc-pipe-A, nonblocking-crc-pipe-A-frame-sequence Signed-off-by:

Sandy Huang authored
Some Rockchip CRTCs, like rv1108 and px30, can directly output parallel and serial RGB data to panel or conversion chip. So add a feature-bit for vops to mark the ability for these direct outputs and add an internal encoder in that case, that can attach to bridge chipsor panels. Changes in v7: 1. forget to delete rockchip_rgb_driver and delete it. Changes in v6: 1. Update according to Heiko Stuebner' implemention, rgb output is part of vop's feature, should not register as a independent driver. Changes in v5: 1. add SPDX-License-Identifier tag Changes in v4: 1. add support px30; Changes in v3: 1. update for rgb-mode move to panel node. Changes in v2: 1. add error log when probe failed; 2. update name_to_output_mode() according to sean's suggest; 3. Fix uninitialized use of ret. Signed-off-by: -

"crtc->helper_private" is not initialized by the QXL driver and thus the "crtc_funcs->disable" call would crash (resulting in suspend failure). Fix this by converting the suspend/resume functions to use the drm_mode_config_helper_* helpers. Tested system sleep with QEMU 3.0 using "echo mem > /sys/power/state". During suspend the following message is visible from QEMU: spice/server/display-channel.c:2425:display_channel_validate_surface: canvas address is 0x7fd05da68308 for 0 (and is NULL) spice/server/display-channel.c:2426:display_channel_validate_surface: failed on 0 This seems to be triggered by QXL_IO_NOTIFY_CMD after QXL_IO_DESTROY_PRIMARY_ASYNC, but aside from the warning things still seem to work (tested with both the GTK and -spice options).

The ioctl arguments are under control of the user and as such we should resist any temptation to flood the kernel logs with their errors. Relegate the DRM_ERROR to a DRM_DEBUG so the user has to opt into hearing of their own mistakes. (One day we will have a small ringbuffer attached to the task, so that the concerned process can inspect its own debug info for EINVAL without them being hitting syslog at all.) Signed-off-by:
