# Graphics overview The Qualcomm^®^ Adreno^™^ GPU powers the graphics subsystem and offers the following capabilities: - Serves as a three-dimensional (3D) graphics accelerator with 64‑bit addressing. - Incorporates the graphics memory (GMEM) as a dedicated memory for the graphics subsystem and facilitates Fast Z, color, and stencil rendering. - Supports 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), [3.0 FP](https://registry.khronos.org/OpenCL/specs/3.0-unified/html/OpenCL_API.html) - **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/80-70018-115/soc.html) that are supported on Qualcomm^®^ Linux^®^. ## Graphics subsystem architecture The graphics architecture consists of Qualcomm and open-source components, as shown in the following figure. **Figure : Graphics subsystem architecture** **Adreno GPU driver** The Qualcomm Adreno GPU driver is a collection of user-mode precompiled libraries and firmware. The Adreno GPU driver can’t be modified and 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/80-70018-19/topic/graphics-overview.html#table-qkn-4bc-ybc) and Table: [GPU driver libraries](https://docs.qualcomm.com/doc/80-70018-19/topic/graphics-overview.html#table-j3s-gl3-kcc) are present on the device in the `/lib/firmware/` and `/usr/lib/` directories respectively. **Adreno GPU firmware** The following table lists the firmware files of the Adreno GPU hardware. > > > Table : GPU firmware files > > > | **Description** | QCS5430/QCS6490 firmware | QCS8275 firmware | QCS9075 firmware | > | --- | --- | --- | --- | > | Microcode for command processor | a660\_sqe.fw | a650\_sqe.fw | a660\_sqe.fw | > | Microcode for secure content support | a660\_zap | a623\_zap | a663\_zap | > | Microcode for graphics management unit (GMU) | a660\_gmu.bin | a663\_gmu.bin | a663\_gmu.bin | **Kernel Graphics Support Layer (KGSL)** 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. > > > **Table : GPU libraries and KGSL driver** > > > > > > | Adreno GPU libraries | KGSL driver | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | > | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | > |
