There’s been a couple of mentions of Rust4Linux in the past week or two, one from Linus on the speed of engagement and one about Wedson departing the project due to non-technical concerns. This got me thinking about project phases and developer types.
“DRM” as in digital restrictions management I assume.
Nope. here it is about the good DRM: Direct Rendering Manager
DRM in this context (as mentioned by the other comment) is the interface between the userspace graphics drivers (Mesa, Nouveau, Nvidia etc.) and your graphics devices. It handles pretty much everything for rendering from displays to power management and memory synchronization, in a cooperative way that stops crashes due to race conditions, memory corruption etc.
