ENUM VSP1_DU_CRC_SOURCE(9)

💅 enum vsp1_du_crc_source(9) — the Kernel API Manual, bestie edition 🎀

okay so picture this: it's a kernel API manual page, it lives in the enum vsp1_du_crc_source(9) section, and it's literally just here to tell you where the CRC math is coming from. That's it. That's the whole gig. And honestly? iconic behaviour. ✨

🌸 NAME 🌸

enum vsp1_du_crc_source — the source used for CRC calculation 🧚

Like, the enum that answers the question "bestie, what are we checksumming?" 💖

---

✨ SYNOPSIS ✨

enum vsp1_du_crc_source {
    VSP1_DU_CRC_NONE ,
    VSP1_DU_CRC_PLANE ,
    VSP1_DU_CRC_OUTPUT

};

Three constants, that's the whole cast. Main character energy from all of them tbh 👑

🫶 Constants 🫶

(this is the subsection, no cap — the constants live here)

• VSP1_DU_CRC_NONE — CRC calculation is disabled. we're not doing math today, bestie, go home 💀
• VSP1_DU_CRC_PLANE — do the CRC calculation on an input plane. yes, the raw plane itself. slay 🦋
• VSP1_DU_CRC_OUTPUT — do the CRC calculation on the composed output. i.e. after everything's been mixed together, which is honestly the glow-up moment 🔥

---

👀 SEE ALSO 👀

the whole friend group, fr fr — first up, the kernel file ./include/media/vsp1.h, then all these structs holding hands in a little circle:

• struct vsp1_du_lif_config(9)
• struct vsp1_du_atomic_config(9)
• struct vsp1_du_crc_config(9)
• struct vsp1_du_writeback_config(9)
• struct vsp1_du_atomic_pipe_config(9)
• struct vsp1_isp_buffer_desc(9)
• struct vsp1_isp_job_desc(9)
• struct vsp1_vspx_frame_end(9)

ngl, that's a lot of structs. they ate though 💅

💡 tiny reminder: the enum itself doesn't crunch any numbers — it just says which source to use. no invented extras here, bestie, i'm just reading the page 🎀

and that's a wrap!! this page was served fresh from ./include/media back in October 2026, filed under enum vsp1_du_crc_source(9) — mwah, go forth and check your checksums 💜🌸⭐
