I'm trying to understand what the difference is between DRM (Direct Rendering Manager) and a graphics driver, such as AMD or Nvidia GPU drivers.
Reading the DRM wiki[1], it seems to me like DRM is basically a graphics hardware driver, however this doesn't explain the existence of proprietary or FOSS graphics drivers for discrete GPUs.
What then, is the difference, or use case, for DRM over mesa or Nvidia drivers? What happens with DRM when AMD drivers are installed? Are they used for different tasks? Are proprietary drivers built around DRM?

DRM is a functionality ( a bunch of standardized API, also allows drivers to implement more) provided by GPU driver. Mesa is different, it's a userland software.
