STRUCT MIPI_DSI_MULTI_CONTEXT(9)

✨ struct mipi_dsi_multi_context 💅 (Kernel API Manual)

okay so picture this: you're in the Kernel API Manual, bestie, and we're talking about struct mipi_dsi_multi_context — literally the context you use to call multiple MIPI DSI funcs in a row. no cap. 🎀

---

🌸 SYNOPSIS 🌸

struct mipi_dsi_multi_context {
    struct mipi_dsi_device *dsi;
    int accum_err;
 };

that's it, that's the whole vibe. two little fields carrying the entire group chat. 🫶

💖 Members 💖

• dsi — a pointer to the MIPI DSI device. like, the actual main character. your device bestie. 🔥
• accum_err — this is where the ✨accumulated error✨ lives after all the multiple calls. storage for the accumulated error over the multiple calls, fr fr.

🦋 the accum_err lore (this is important, don't skip) 🦋

Init to 0. 🫡 that's the starting state, the fresh-faced era, the pre-drama moment.

if a function encounters an error then the error code will be stored here. so yes — the bad news has a home. 😭

and here's the iconic part: if you call a function and this points to a non-zero value, then the function will be a noop. literally nothing. a vibe check that just says "nope." 💀

the way that this works out is: you can call a function many times in a row and just check the error at the end to see if any of them failed. one single check at the finish line instead of a hundred little panics along the way. efficiency queen. 👑✨

that's the page, bestie! this whole thing lives in ./include/drm, it's part of the Kernel API Manual, and it's dated October 2026 — so go forth, accumulate your errors, and only check them at the end like a calm and collected icon. slay. 💅✨🍓
