Pointer dev_priv->mmio, which was checked for NULL at via_do_init_map(), is passed to via_do_cleanup_map() and is dereferenced there without check. The patch adds the condition in via_dma_cleanup() which prevents potential NULL pointer dereference. Found by Linux Verification Center (linuxtesting.org) with SVACE.

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).

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.

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.

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.

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.

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:

Like commit c4f135d6 ("workqueue: Wrap flush_workqueue() using a macro") says, flush_scheduled_work() is dangerous and will be forbidden. We are on the way for removing all flush_scheduled_work() callers from the kernel, and this patch is for removing flush_scheduled_work() call from cadence driver. Since cdns-mhdp8546 driver uses 4 works mhdp->modeset_retry_work mhdp->hpd_work mhdp->hdcp.check_work mhdp->hdcp.prop_work I assume that flush_scheduled_work() in cdns_mhdp_remove() needs to wait for only these 4 works. Since mhdp->modeset_retry_work already uses cancel_work_sync(), I assume that flush_scheduled_work() needs to wait for only 3 works. But I came to wonder whether mhdp->hdcp.check_work should be flushed or cancelled. While flush_scheduled_work() waits for completion of works which were already queued to system_wq, mhdp->hdcp.check_work is a delayed work. That is, this work won't be queued to system_wq unless timeout expires. Current code will wait for mhdp->hdcp.check_work only if timeout already expired. If timeout is not expired yet, flush_scheduled_work() will fail to cancel mhdp->hdcp.check_work, and cdns_mhdp_hdcp_check_work() which is triggered by mhdp->hdcp.check_work will schedule hdcp->check_work, which is too late for flush_scheduled_work() to wait for completion of cdns_mhdp_hdcp_prop_work(). But since I couldn't get comments on how do we want to handle this race window [1], this patch chose "do nothing" for mhdp->hdcp.check_work and mhdp->hdcp.prop_work. That is, I assume that flush_scheduled_work() in cdns_mhdp_remove() needs to wait for only mhdp->hpd_work work.

Convert to io-pgtable's bulk {map,unmap}_pages() APIs, to help the old single-page interfaces eventually go away. Unmapping heap BOs still wants to be done a page at a time, but everything else can get the full benefit of the more efficient interface. Signed-off-by:Robin Murphy <robin.murphy@arm.com> Acked-by:
