The reset line is deasserted at bind, and asserted if we ever encounter an error there. However, it's never asserted in unbind which will lead to a resource unbalance. Reviewed-by:

The other error labels in sun4i_tv_bind() are named after the task they perform (err_disable_clk to call clk_disable_unprepare for example). However, the err_cleanup_connector is named after the calling site (drm_connector_init failing) and will actually cleanup the encoder. Let's rename it to err_cleanup_encoder to be consistent.

This commit fixes vertical timings of the VEC (composite output) modes to accurately represent the 525-line ("NTSC") and 625-line ("PAL") ITU-R standards. Previous timings were actually defined as 502 and 601 lines, resulting in non-standard 62.69 Hz and 52 Hz signals being generated, respectively.

We will remove the current assumption that the primary plane has the same size and position as CRTC and that the primary plane is the bottom-most in zpos order, or is even enabled. At least as far as the blending machinery is concerned. For that we will add CRTC dimension information to `vkms_crtc_state` and add a opaque black backgound color. Because now we need to fill the background, we had a loss in performance with this change.

Currently the blend function only accepts XRGB_8888 and ARGB_8888 as a color input. This patch refactors all the functions related to the plane composition to overcome this limitation. The pixels blend is done using the new internal format. And new handlers are being added to convert a specific format to/from this internal format. So the blend operation depends on these handlers to convert to this common format. The blended result, if necessary, is converted to the writeback buffer format. This patch introduces three major differences to the blend function. 1 - All the planes are blended at once. 2 - The blend calculus is done as per line instead of per pixel. 3 - It is responsible to calculates the CRC and writing the writeback buffer(if necessary). These changes allow us to allocate way less memory in the intermediate buffer to compute these operations. Because now we don't need to have the entire intermediate image lines at once, just one line is enough. | Memory consumption (output dimensions) | |:--------------------------------------:| | Current | This patch | |:------------------:|:-----------------:| | Width * Heigth | 2 * Width | Beyond memory, we also have a minor performance benefit from all these changes.

This commit is the groundwork to introduce new formats to the planes and writeback buffer. As part of it, a new buffer metadata field is added to `vkms_writeback_job`, this metadata is represented by the `vkms_frame_info` struct. Also adds two new function pointers (`line_to_frame_func` and `frame_to_line_func`) are defined to handle format conversion from/to internal format. A new internal format(`struct pixel_argb_u16`) is introduced to deal with all possible inputs. It consists of 16 bits fields that represent each of the channels. These things will allow us, in the future, to have different compositing and wb format types. V2: Change the code to get the drm_framebuffer reference and not copy its contents (Thomas Zimmermann). V3: Drop the refcount in the wb code (Thomas Zimmermann). V5: Add {wb,plane}_format_transform_func to vkms_writeback_job and vkms_plane_state (Pekka Paalanen) V6: Improvements to some struct/struct members names (Pekka Paalanen). Splits this patch in two (Pekka Paalanen). V7: Replace line_to_frame_func and frame_to_line_func typedefs with the function signature and void* (Melissa Wen). Reviewed-by: -

Changes the name of this struct to a more meaningful name. A name that represents better what this struct is about. Composer is the code that do the compositing of the planes.

When registering a connector, the kernel sends a hotplug uevent in drm_connector_register(). When unregistering a connector, drivers are expected to send a uevent as well. However, user-space has no way to figure out that the connector isn't registered anymore: it'll still be reported in GETCONNECTOR IOCTLs. The documentation for DRM_CONNECTOR_UNREGISTERED states: > The connector […] has since been unregistered and removed from > userspace, or the connector was unregistered before it had a chance > to be exposed to userspace Signed-off-by:

From the DP spec 1.4a chapter 3.3, upstream devices should implement HPD signal de-bouncing on an external connection. A period of 100ms should be used to detect an HPD connect event. To cover these cases, HPD de-bounce should be implemented only after HPD low has been detected for at least 100ms. Therefore, 1. If HPD is low (which means plugging out) for longer than 100ms: we need to do de-bouncing (which means we need to wait for 100ms). 2. If HPD low is for less than 100ms: we don't need to care about the de-bouncing. In this patch, we start a 100ms timer and use a need_debounce boolean to implement the feature. Two cases when HPD is high: 1. If the timer is expired (>100ms): - need_debounce is true. - When HPD high (plugging event comes), need_debounce will be true and then we need to do de-bouncing (wait for 100ms). 2. If the timer is not expired (<100ms): - need_debounce is false. - When HPD high (plugging event comes), need_debounce will be false and no need to do de-bouncing. HPD_______ __________________ | |<- 100ms -> |____________| <- 100ms -> Without HPD de-bouncing, USB-C to HDMI Adapaters will not be detected. The change has been successfully tested with the following devices: - Dell Adapter - USB-C to HDMI - Acer 1in1 HDMI dongle - Ugreen 1in1 HDMI dongle - innowatt HDMI + USB3 hub - Acer 2in1 HDMI dongle - Apple 3in1 HDMI dongle (A2119) - J5Create 3in1 HDMI dongle (JAC379) Tested-by:Jitao Shi <jitao.shi@mediatek.com> Signed-off-by:

This patch adds a embedded displayport driver for the MediaTek mt8195 SoC. It supports the MT8195, the embedded DisplayPort units. It offers DisplayPort 1.4 with up to 4 lanes. The driver creates a child device for the phy. The child device will never exist without the parent being active. As they are sharing a register range, the parent passes a regmap pointer to the child so that both can work with the same register range. The phy driver sets device data that is read by the parent to get the phy device that can be used to control the phy properties. This driver is based on an initial version by Jitao shi <jitao.shi@mediatek.com> Signed-off-by:

Similar to HDMI, DP uses audio infoframes as well which are structured very similar to the HDMI ones. This patch adds a helper function to pack the HDMI audio infoframe for DP, called hdmi_audio_infoframe_pack_for_dp(). hdmi_audio_infoframe_pack_only() is split into two parts. One of them packs the payload only and can be used for HDMI and DP. Also constify the frame parameter in hdmi_audio_infoframe_check() as it is passed to hdmi_audio_infoframe_check_only() which expects a const. Signed-off-by:
