# Overview Source: [https://docs.qualcomm.com/doc/80-70015-19/topic/graphics-overview.html](https://docs.qualcomm.com/doc/80-70015-19/topic/graphics-overview.html) The graphics subsystem is powered by the Qualcomm^®^ Adreno™ GPU. The Adreno GPU is a three-dimensional (3D) graphics accelerator with 64‑bit addressing and incorporates the graphics memory (GMEM). The GMEM serves as a dedicated memory for the graphics subsystem and facilitates Fast Z, color, and stencil rendering. Additionally, the Adreno GPU supports the Qualcomm^®^ Universal Bandwidth Compression, enhancing the overall performance. The Adreno GPU supports the following graphics and compute APIs: - **OpenGL ES**: [3.0](https://registry.khronos.org/OpenGL/specs/es/3.0/es_spec_3.0.pdf), [3.1](https://registry.khronos.org/OpenGL/specs/es/3.1/es_spec_3.1.pdf), [3.2](https://registry.khronos.org/OpenGL/specs/es/3.2/es_spec_3.2.pdf) - **OpenCL**: [1.2 FP](https://registry.khronos.org/OpenCL/specs/opencl-1.2.pdf), [2.0 FP](https://registry.khronos.org/SPIR-V/specs/1.0/OpenCL.std.20.pdf) - **EGL**: [1.5](https://registry.khronos.org/EGL/specs/eglspec.1.5.pdf) - **Vulkan**: [1.1](https://registry.khronos.org/vulkan/#vulkan1.1) Note: See [Hardware SoCs](https://docs.qualcomm.com/bundle/publicresource/topics/80-70015-115/soc.html) that are supported on Qualcomm^®^ Linux^®^. ### Architecture Figure : Graphics subsystem architecture **Adreno GPU driver** The Adreno GPU driver is a collection of user-mode precompiled libraries and firmware developed by Qualcomm. The Adreno GPU driver must be used as-is. Note: To use all the features supported by the Adreno GPU, ensure that the files listed in the [Table : GPU firmware files](https://docs.qualcomm.com/doc/80-70015-19/topic/graphics-overview.html#graphics-home__table_qkn_4bc_ybc) and [Table : GPU libraries and KGSL driver](https://docs.qualcomm.com/doc/80-70015-19/topic/graphics-overview.html#graphics-home__table_j3s_gl3_kcc) are present on the device at /lib/firmware/. **Adreno GPU firmware** The following table lists the firmware files of the Adreno GPU hardware. Table : GPU firmware files | **Description** | QCS5430/QCS6490 firmware | QCS9075 firmware | | --- | --- | --- | | Microcode for command processor | a660\_sqe.fw | a660\_sqe.fw | | Microcode for secure content support | a660\_zap | a663\_zap | | Microcode for graphics management unit (GMU) | a660\_gmu.bin | a660\_gmu.bin | **Kernel Graphics Support Layer (KGSL)** The KGSL serves as the kernel-mode driver for the Adreno GPU. The primary function of the KGSL driver is to submit commands generated by the Adreno user-mode driver to the Adreno GPU for processing. Additionally, the KGSL driver communicates with the GMU to ensure proper state management. The following table lists the supported GPU libraries and KGSL driver. | Adreno GPU libraries | KGSL driver | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | |
