**Figure : DPU hardware architecture block diagram** The following table lists the components of the display software architecture. Table : Display hardware architecture components | Component | Description | | --- | --- | | Bus interface | Fetches data from memory for processing | | Source surface processing | | | Blending | Blends and mixes source surface together | | Destination surface processing | Converts, corrects, and adjusts the data based on panel
characteristics | | Compression | Reduces bandwidth and power consumption by sending compressed
display buffers to the display | | Display interface | Generates timings for the connected display peripherals | Detailed information on the display hardware architecture is available to licensed developers with authorized access.

**Figure : Display software architecture block diagram** Note QCS6490/QCS5430 continues to support SDM backend. For more information, see [Qualcomm Linux Display Guide - Addendum](https://docs.qualcomm.com/bundle/resource/topics/80-70017-18A/architecture.html#advanced-features) The components of the display software architecture are described as follows: > > > | Component | Description | > | --- | --- | > | Wayland sink | The Wayland sink plug-in communicates with the Weston
subsystem to render the display.. | > | Wayland compositor (Weston) | A display server using the Wayland protocol is called a
Wayland compositor. The Wayland compositor is a system-level
compositor, which handles the composition and rendering
requirements and runs as a separate process in the system.
The reference implementation of a Wayland compositor is
called Weston. | > | DRM backend | The DRM backend software framework manages Qualcomm Adreno DPU hardware
resources. It selects the optimal composition strategy for
each connected display and allocates display processor
hardware resources for the layer stack received from the
client. | > | `libdrm` | The `libdrm` library provides APIs for accessing the Direct
Rendering Manager (DRM) I/O control (IOCTL). | > | DRM/KMS framework | The DRM/KMS framework offers kernel and userland level
interface, with the help of `libdrm` libraries to
access the related hardware features, configuration, and
hardware acceleration. | > | Adreno DPU driver | The Adreno DPU driver manages all the pixel data paths to
different panel interfaces. | > | Adreno DPU | The Adreno DPU is a hardware accelerated engine that performs
the image processing and interfacing with minimal power
consumption. | Detailed information on the architecture components is available to licensed developers with authorized access. For more information, see the following topics in [Qualcomm Linux Display Guide - Addendum](https://docs.qualcomm.com/bundle/resource/topics/80-70017-18A/architecture.html#display-software-architecture). > > > - **DRM/KMS Adreno DPU driver architecture**: the DRM/KMS Linux kernel framework and related drivers are used to access the display hardware block. > - **Display peripheral interfaces**: the display interface consists of the MIPI DSI controller, the DP controller, and the eDP controller. ## Software APIs The Qualcomm Linux software interface provides the following display APIs: - Weston API: facilitates interactions with the SDM compositor. For the Weston APIs, see [Wayland client APIs](https://wayland.freedesktop.org/docs/html/apb.html) and [Wayland server APIs](https://wayland.freedesktop.org/docs/html/apc.html). - `libdrm` API: facilitates interactions with the DRM/KMS framework. For the APIs, see [libdrm](https://dri.freedesktop.org/docs/drm/gpu/drm-uapi.html). Qualcomm provides you the GStreamer-based plugins. You can add the Waylandsink plugin to your media pipeline from [IM SDK plugins](https://docs.qualcomm.com/bundle/publicresource/topics/80-70017-50/qim-sdk-plugins.html). For more information, see [GStreamer application development and pipeline creation](https://gstreamer.freedesktop.org/documentation/application-development/basics/index.html). ## Display software directory and bringup instructions ### Software Explores the user space and kernel space modules, which are available in the Qualcomm Linux-enabled display software directory. The software modules are available to licensed developers with authorized access. For more information, see [Qualcomm Linux Display Guide - Addendum](https://docs.qualcomm.com/bundle/resource/topics/80-70017-18A/software.html). ### Bringup Explains the process to bring up the DSI display panel in the kernel, as well as the guidelines for panel selection and customization, and bring up eDP. The bringup information is available to licensed developers with authorized access. For more information, see [Qualcomm Linux Display Guide - Addendum](https://docs.qualcomm.com/bundle/resource/topics/80-70017-18A/bringup.html).
