STRUCT HEVC_FB(9)

🌸 NAME — struct hevc_fb(9) 🌸

okay so bestie, welcome to the Kernel API Manual page for struct hevc_fb(9) — the manual name is literally folded in right here like a lil ribbon 🎀. This page is all about struct hevc_fb, which is hevc decode frame buffer information. That's the whole vibe: HEVC decode frame-buffer info, no cap ✨.

💅 SYNOPSIS 💅

the struct itself is giving exactly this, and yes bestie, copy it character for character:

       struct hevc_fb {
           u64 vdec_fb_va;
           u64 y_fb_dma;
           u64 c_fb_dma;
           s32 poc;
           u32 reserved;
        };

🎀 Members 🎀

• vdec_fb_va — virtual address of struct vdec_fb. virtual address bestie, that's where the struct lives in memory-vibe land 💖
• y_fb_dma — dma address of the Y frame buffer (luma). the luma buffer is main character energy, fr ✨
• c_fb_dma — dma address of the C frame buffer (chroma). chroma sidekick, slay 🦋
• poc — picture order count of the frame buffer. it's giving picture order count, not a snack, periodt 👑
• reserved — for 8 bytes alignment. 8 bytes alignment queen — keeping the struct cute and aligned 🎀
