STRUCT DC_VALIDATION_SET(9)

🎀 struct dc_validation_set(9) — Kernel API Manual 🎀

okay so bestie, meet struct dc_validation_set: the root validation input that groups all streams for a commit into one struct. no cap, it's basically the group chat for a commit's validation streams — everything shows up in one place. 💅✨

💖 NAME 💖

struct dc_validation_set — root validation input grouping all streams for a commit 🫶

🌈 SYNOPSIS 🌈

       struct dc_validation_set {
           struct dc_validation_stream streams[MAX_STREAMS];
           uint8_t stream_count;
           struct dc_probe_state probes[MAX_PROBES];
           uint8_t probe_count;
        };

🧚 Members 🧚

bestie, this struct carries four members, and yes, we're covering every single one:

• streams — per-stream entries (stream + its planes) 💫
• stream_count — number of active entries in streams 🔢
• probes — global probe descriptors to validate alongside the streams 🫶
• probe_count — number of active entries in probes 🔢
