ENUM IRIS_BUFFER_TYPE(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 enum iris_buffer_type(9) 🌸

okay bestie, so this is a page from the Kernel API Manual (yes, that Kernel API Manual 💅) and it's all about enum iris_buffer_type — one enum, fourteen constants, zero chill. Let's get into it ✨

NAME

enum iris_buffer_type — and honestly? that's it. The description is blank. She said "my name is enough" and left. main character energy fr fr 👑

SYNOPSIS

enum iris_buffer_type {
    BUF_INPUT ,
    BUF_OUTPUT ,
    BUF_BIN ,
    BUF_ARP ,
    BUF_COMV ,
    BUF_NON_COMV ,
    BUF_LINE ,
    BUF_DPB ,
    BUF_PERSIST ,
    BUF_SCRATCH_1 ,
    BUF_SCRATCH_2 ,
    BUF_VPSS ,
    BUF_PARTIAL ,
    BUF_TYPE_MAX

};

look at her. fourteen entries. not one of them skipped. we love a complete list 🫶

Constants 🎀

every single one, in order, no cap:

  • BUF_INPUT — input buffer to the iris hardware 🌈
  • BUF_OUTPUT — output buffer from the iris hardware 🦋
  • BUF_BIN — buffer to store intermediate bin data 💫
  • BUF_ARP — buffer for auto register programming ⭐
  • BUF_COMV — buffer to store colocated motion vectors 🔥
  • BUF_NON_COMV — buffer to hold config data for HW 👑
  • BUF_LINE — buffer to store decoding/encoding context data for HW 🎀
  • BUF_DPB — buffer to store display picture buffers for reference 💜
  • BUF_PERSIST — buffer to store session context data 🌸
  • BUF_SCRATCH_1 — buffer to store decoding/encoding context data for HW 🧚
  • BUF_SCRATCH_2 — buffer to store encoding context data for HW ✨
  • BUF_VPSS — buffer to store VPSS context data for HW 💖
  • BUF_PARTIAL — buffer for AV1 IBC data 💅
  • BUF_TYPE_MAX — max buffer types 💀
ngl bestie, BUF_LINE and BUF_SCRATCH_1 literally have the exact same description — "buffer to store decoding/encoding context data for HW". That's not a typo on my end, that's just how the page says it. iykyk 🙈

SEE ALSO 👀

  • Kernel file ./drivers/media/platform/qcom/iris/iris_buffer.h struct iris_buffer(9)

like, go read the actual header and the struct if you want the full lore. the enum is giving "table of contents" energy.

and that's the whole page, bestie — every constant, every description, nothing dropped 🍓

mwah 💋 — this gem came from ./drivers/media/platform/qcom/... and it's dated October 2026, so mark your calendar, she's freshly stamped and ready. periodt.
