STRUCT DRM_GPUSVM_RANGE(9)

💅 struct drm_gpusvm_range(9) 💅

okay so bestie, we're in the Kernel API Manual and the main character of this page is struct drm_gpusvm_range(9). It's one struct, it's giving range-tracking realness, and we are gonna read every single member together. No skimming, no cap. ✨

🌸 NAME 🌸

struct drm_gpusvm_range — Structure representing a GPU SVM range. periodt. 💖

🦋 SYNOPSIS 🦋

struct drm_gpusvm_range {
    struct drm_gpusvm *gpusvm;
    struct drm_gpusvm_notifier *notifier;
    struct kref refcount;
    struct interval_tree_node itree;
    struct list_head entry;
    struct drm_gpusvm_range_flags flags;
 };

🎀 Members 🎀

okay, member-by-member vibe check:

• gpusvm — Pointer to the GPU SVM structure. iconic pointer behavior.
• notifier — Pointer to the GPU SVM notifier.
• refcount — Reference count for the range.
• itree — Interval tree node for the range (inserted in GPU SVM notifier).
• entry — List entry to fast interval tree traversal.
• flags — Flags for range, see struct drm_gpusvm_range_flags.

💜 Description 💜

This structure represents a GPU SVM range used for tracking memory ranges mapped in a DRM device. That's the whole assignment: it's the struct holding down the range-tracking situation for DRM device memory mappings. 🫶
