Linux Graphics 101
summary
Overview of the Linux graphics stack that names actual components and workflows: kernel handles memory via GEM vs TTM, exposes IOCTLs for buffer objects and command stream submission, and schedules with DRM sched; user space (Mesa) performs shader compilation GLSL → SPIR‑V → NIR → GPU ISA, uses Gallium state tracker with drivers like Panfrost, Etnaviv, Freedreno and Intel Iris, and syncs with fences; testing relies on Piglit and dEQP; talk runs ~30 minutes.
