STRUCT VP9_REF_CNT_BUF(9)

hii bestie 💖 you're reading the Kernel API Manual page for struct vp9_ref_cnt_buf(9), and it's a short one but it's lowkey iconic for reference buffer info. let's get into it 🎀

✨ NAME ✨

struct vp9_ref_cnt_buf — contains reference buffer information. that's the whole name, and honestly it's giving “I hold the reference-buffer receipts” 🌸

🦋 SYNOPSIS 🦋

ok so the struct is literally this, no cap:

struct vp9_ref_cnt_buf {
    struct vp9_fb_info buf;
    unsigned int ref_cnt;
 };

🫶 Members 🫶

two members, both main characters 💅

• buf — referenced frame buffer. it's the referenced frame buffer, periodt 🫶
• ref_cnt — referenced frame buffer's reference count. When reference count=0, remove it from reference list. so yeah, when reference count=0, remove it from reference list — that's the rule for the reference list 💀✨
