SRM

 

Simple Rendering Manager

SRM is released under the GPL v3.0 license. Current SRM version.

SRM is a C library that simplifies the development of Linux DRM/KMS applications.

With SRM, you can focus on the OpenGL ES 2.0 logic of your application. For each available display, you can start a rendering thread that triggers common events like initializeGL(), paintGL(), resizeGL(), pageFlipped() and uninitializeGL().

SRM allows you to use multiple GPUs simultaneously and automatically finds the most efficient configuration. It also offers functions for creating OpenGL textures, which are automatically shared among GPUs.

Features

  • Multiple GPUs support
  • Automatic optimal GPUs/connectors configuration
  • Automatic texture sharing between GPUs
  • Texture allocation from CPU buffers, DMA buffers, GBM BOs, Flink Handles, Wayland DRM buffers.
  • Multi seat support (libseat can be used to open DRM devices for example)
  • GPU hot-plugging event listener
  • Connectors hot-plugging event listener
  • Hardware cursor compositing
  • V-Sync
  • Frame buffer damage (improves performance when DMA is not supported)
  • Access to renderbuffers as textures.

Tested on

  • Intel GPUs (i915 driver)
  • NVIDIA GPUs (Nouveau and propietary drivers)
  • Mali GPUs (Lima driver)

Creating an OpenGL app without display server on Linux (tutorial)

Imagen
Are you in the process of crafting an OpenGL application but wish to remain independent of display servers like Wayland or X11? Perhaps you're developing a graphical application for a resource-constrained embedded device, or you've ventured into the creation of your own display server, only to encounter challenges when using the low-level DRM/KMS API. If any of these scenarios resonate with you, you've come to the right place. In this tutorial, we will guide you through the process of creating an OpenGL application using the SRM library, which stands for Simple Rendering Manager. This library streamlines the configuration of all available GPUs and displays, allowing you to concentrate on developing your OpenGL ES 2.0 application. Moreover, it offers valuable features such as listeners for display hotplugging events, such as HDMI display connections and disconnections. Additionally, it facilitates rendering with multiple GPUs and enables texture sharing between them, all thr

SRM v0.2.0-1 Release

Imagen
SRM (0.2.0-1) Release Notes Additions: Introducing  srmCoreSuspend()  and  srmCoreResume()  functions for seamless libseat session switching. New  srmConnectorGetRendererDevice()  function simplifies OpenGL texture ID retrieval, reducing repetitive calls. Internal Changes: Transitioned from using poll to epoll for more efficient udev monitor event handling. Bug Fixes: Udev hotplugging events are now queued during SRM suspension and emitted upon restoration, resolving connector initialization issues. Fixed the bug where connector rendering threads did not block when suspended. Learn more and download on  GitHub . Cuarzo Software
