STRUCT MXC_JPEG_SOS(9)

💅 NAME 💅

okay so bestie, gather round, because this is struct mxc_jpeg_sos — the struct that holds all the JPEG Start Of Scan marker fields. no cap, that's literally its whole job. it's giving "small but essential" energy and we respect it. ✨

(this whole thing lives in the Kernel API Manual, section 9, and yes we're getting into kernel struct lore today 🎀)

---

🌸 SYNOPSIS 🌸

here's the glow-up itself, and you're gonna copy it exactly, ok? character for character, no freestyling:

struct mxc_jpeg_sos {
    u16 length;
    u8 components_no;
    struct mxc_jpeg_sos_comp comp[MXC_JPEG_MAX_COMPONENTS];
    u8 ignorable_bytes[3];
 };

look at that little guy. four fields. immaculate vibes. 💖

okay let's meet the cast, one by one, main character energy for all of them:

• length — the Start of Frame length. yes fr, that's what the docs say, and we're reporting it faithfully, bestie. it's a u16, it's here, it's doing its thing. 🙈
• components_no — the number of color components. a u8. it literally tells you how many color components we're dealing with. lowkey important. 🔥
• comp — the SOS component fields for each color component! it's an array of struct mxc_jpeg_sos_comp, sized MXC_JPEG_MAX_COMPONENTS, so every color component gets its own little slot. obsessed. 🦋
• ignorable_bytes — ignorable bytes. that's it, that's the description, they're bytes and you can ignore them 💀 it's a u8 array of [3], and honestly? iconic for being that upfront about it. 🫶

👑 SEE ALSO 👑

go read these next, i'm literally begging you, the lore is deep:

• Kernel file ./drivers/media/platform/nxp/imx-jpeg/mxc-jpeg.h
• struct mxc_jpeg_fmt(9)
• struct mxc_jpeg_sof_comp(9)
• struct mxc_jpeg_sof(9)
• struct mxc_jpeg_sos_comp(9)

like, read the whole friend group, not just one of them. iykyk. 🌈

ngl the synopsis is the part people actually copy, so keep those field names and types exactly as written — u16 length, u8 components_no, struct mxc_jpeg_sos_comp comp[MXC_JPEG_MAX_COMPONENTS], u8 ignorable_bytes[3]. no renaming, no merging, no "improving". periodt. 💅

and that's the page!! 🎀 it comes to you from source ./drivers/media/platform/nxp/i... (yes it's truncated in the footer, that's just how it is, don't come for me 😭) and it's dated October 2026 — so go forth, cite struct mxc_jpeg_sos(9) correctly, and slay your kernel reading era. bye bestie, drink water, read your headers 🍓⭐💜
