💅 struct vsp1_dl_ext_header(9) — the Kernel API Manual, but make it cute

🌸 SYNOPSIS 🌸

struct vsp1_dl_ext_header {
    u32 padding;

    u16 flags;
    u32 pre_ext_dl_plist;
    u32 post_ext_dl_num_cmd;

👑 Members 👑

• padding — padding zero bytes for alignment. yes literally just zeros hanging out so everything lines up pretty ✨ lowkey the most relatable field on the whole page.
• pre_ext_dl_num_cmd — number of pre-extended command bodies to parse 🔥 that's the count, that's the job.
• flags — enables or disables execution of the pre and post command. it's the on/off switch vibe check for both sides 🫶
• pre_ext_dl_plist — start address of pre-extended display list bodies 📍 like the "you are here" pin for the pre side.
• post_ext_dl_num_cmd — number of post-extended command bodies to parse 💀 same count energy, post flavour.
• post_ext_dl_plist — start address of post-extended display list bodies 📍 and here's the pin for the post side. main character address, fr fr.
