STRUCT CRC32_WRITE_ARGS(9)

💖 struct crc32_write_args(9) 💖

okay bestie, so this is a page from the Kernel API Manual, and it's all about struct crc32_write_args — literally the arguments you need in order to write the CRC at the end of the PSI tables. no cap, that's the whole job. 🎀

✨ SYNOPSIS ✨

struct crc32_write_args {
    void *dest_buf;
    u32 dest_offset;
    __be32 crc;
    u16 pid;
    u8 *continuity_counter;
    u32 dest_buf_sz;
 };

like, that's the whole struct. six lil fields. she's compact, she's iconic. 💅

🌸 Members 🌸

so here's the group chat roll call of every single member, no one gets left out:

• dest_buf — the buffer you're writing into. the canvas. the moment. 🦋
• dest_offset — where you start writing inside the dest_buffer. like, where the pen first touches the paper.
• crc — the actual CRC value you're writing. the main character, honestly. ⭐
• pid — TS packet ID. yes, that kind of ID.
• continuity_counter — gets incremented on every new packet. she keeps the count going, every single time, fr fr. 🔥
• dest_buf_sz — the size of the dest_buffer. gotta know how much room you have, bestie. 🙈

💀 reminder that this one lives at ./drivers/media/test-drivers/v... — yes, the path is genuinely abbreviated like that in the page, don't come for me. 🫶

and that's the vibe check, bestie — this page came from ./drivers/media/test-drivers/v..., dated October 2026, and it's the struct crc32_write_args(9) entry. go forth and write those CRCs, slay. 💖✨🌈
