✨ exynos_drm_ipp_register(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for exynos_drm_ipp_register — yes that's a mouthful, yes we're gonna get through it together 🫶

---

🌸 NAME 🌸

exynos_drm_ipp_register — registers a brand new picture processor hardware module, no cap 💅

---

🦋 SYNOPSIS 🦋

int exynos_drm_ipp_register (struct device *dev , struct exynos_drm_ipp
*ipp , const struct exynos_drm_ipp_funcs *funcs , unsigned int caps ,
const struct exynos_drm_ipp_formats *formats , unsigned int num_formats
, const char *name );

like… that's the whole signature, and it's a lot, so let's break it down one by one 🔥

---

🎀 ARGUMENTS 🎀

• dev — the DRM device, the main character in this whole situation 👑
• ipp — the ipp module you're about to init, so basically the thing getting its glow-up ✨
• funcs — the callbacks for your new ipp object, iykyk 🧚
• caps — a bitmask of ipp capabilities, and the flags all live under DRM_EXYNOS_IPP_CAP_* 💖
• formats — an array of all the formats this thing supports, iconic 🎀
• num_formats — the size of that supported formats array, so it knows how many to look at 🙈
• name — a name, and lowkey it's just for debugging purposes, but give it a cute one anyway 🍓

---

💜 DESCRIPTION 💜

so what does it actually do? it initializes an ipp module. that's it, that's the vibe — short and sweet, periodt 🌈

---

⭐ RETURN ⭐

• 0 (zero) on success — slay 💅
• an error code on failure — not slay, but we move 😭

🔮 SEE ALSO 🔮

the kernel file lives right here, go look:

./drivers/gpu/drm/exynos/exynos_drm_ipp.c

and the whole friend group of related calls: exynos_drm_ipp_unregister(9), exynos_drm_ipp_get_res_ioctl(9), exynos_drm_ipp_get_caps_ioctl(9), exynos_drm_ipp_get_limits_ioctl(9), exynos_drm_ipp_task_done(9), exynos_drm_ipp_commit_ioctl(9) — go follow them, they're all in the same era 💜

ngl if your registration fails, read the return value before you start crying. the error code is literally telling you what went wrong. use the information, bestie 🫶

and that's the whole page!! source/version situation: it lives under ./drivers/gpu/drm/exynos, dated October 2026, and it's literally titled exynos_drm_ipp_register(9) in the Kernel API Manual. mwah, bookmark it, annotate it, put it on your fridge 💖✨🎀
