The Direct Rendering Manager (DRM) is a subsystem of the Linux kernel responsible for interfacing with GPUs of modern video cards. DRM exposes an API that user-space programs can use to send commands and data to the GPU and perform operations such as configuring the mode setting of the display. DRM was first developed as the kernel-space component of the X Server Direct Rendering Infrastructure, but since then it has been used by other graphic stack alternatives such as Wayland. User-space programs can use the DRM API to command the GPU to do hardware-accelerated 3D rendering and video decoding, as well as GPGPU computing. (en) Der Direct Rendering Manager (abgekürzt DRM) ist ein Hardware-spezifisches Kernel-Modul (Treiber), der auch ohne einen X-Server wie X.org-Server Zugriff auf den Speicher (DMA, AGP) der Grafikkarte gewährt. Außerdem stellt der DRM sicher, dass die definierten Sicherheitsregeln eingehalten und die Zugriffe auf die Hardware verwaltet werden. DRM ist ein Teil der Direct Rendering Infrastructure (DRI). (de) Direct Rendering Manager (Gestor de Renderizado Directo o DRM) es un componente de Direct Rendering Infrastructure (Infraestructura de Renderizado Directo o DRI), que provee a sistemas operativos tipo Unix, como Linux, FreeBSD, NetBSD, y OpenBSD de aceleración gráfica eficiente, especialmente para aplicaciones 3D. Consiste en dos módulos del kernel: un módulo genérico llamado drm, y otro específico para el chipgráfico de que conste el hardware. Estos dos drivers en conjunto permiten que un cliente en elespacio de usuario (userspace) pueda acceder al hardware de vídeo de manera más o menos directa,acelerando de este modo la producción de imágenes. (es) Direct Rendering Manager (gestionnaire de rendu direct en anglais), abrégé en DRM est un sous-système du noyau linux, servant à la gestion cohérente au sein du système informatique, du mode d'affichage (modesetting), des tampons mémoires utilisés par le système graphique, de la gestion de objets partagés en mémoire, de la gestion de la queue de commandes au processeur graphique, la gestion de l'intervalle de rafraîchissement vertical, ainsi que la synchronisation inter-processus de toutes ces fonctions. Il expose ainsi à l'espace utilisateur une interface unifiée pour une gestion plus cohérente et plus simple que ses prédécesseurs.

O DRM expõe uma API que os programas de espaço de usuário podem usar para enviar comandos e dados para a GPU, e para executar operações, como configurar o modo de exibição do monitor. O DRM foi desenvolvido inicialmente como o componente de espaço do kernel do Direct Rendering Infrastructure do servidor X, mas desde então tem sido usado por outras alternativas de pilha gráfica como o Wayland. Os programas de espaço do usuário podem usar a API do DRM para comandar a GPU para fazer a renderização em 3D e a decodificação de vídeo , além da computação GPGPU. (pt) |
