💅 caam_drv_ctx_update(9)

✨ NAME ✨

caam_drv_ctx_update — Update QI driver context 🔥

---

🌸 SYNOPSIS 🌸

int caam_drv_ctx_update (struct caam_drv_ctx *drv_ctx , u32 *sh_desc );

not me copying this exactly, but like… character for character, no cap 💀

---

🦋 ARGUMENTS 🦋

• drv_ctx — the driver context that's getting updated, bestie. this is the thing you're swapping stuff into 👑
• sh_desc — the new shared descriptor pointer, the one that gets updated in the QI driver context. fresh pointer, who dis 💅

---

💖 DESCRIPTION 💖

So here's the vibe: you call this when the shared descriptor needs to be changed in the driver context. That's it. That's the whole plot 🧚

And the return situation? It returns 0 on success, or a negative error code on failure. So like — zero is good, negative is giving bad news 😭

fr fr, check that return value. negative error code = something did NOT go how you wanted 🙈
