💅 omap44xx_prm_was_any_context_lost_old — the Kernel API Manual era 🎀

okay so bestie, this is a page from the Kernel API Manual, and honestly? it's giving detective energy. we're checking if a module lost its little hardware memories. let's get into it ✨

🦋 NAME 🦋

omap44xx_prm_was_any_context_lost_old — lowkey asking: did this module lose its hardware context? 😭

---

🌸 SYNOPSIS 🌸

bool omap44xx_prm_was_any_context_lost_old(u8 part, s16 inst, u16 idx);

that's it. three args, one bool. cute, clean, iconic. 💖

---

✨ ARGUMENTS ✨

• part — the PRM partition ID, like OMAP4430_PRM_PARTITION. think of it as the neighborhood bestie 🏘️
• inst — the PRM instance offset, like OMAP4430_PRM_MPU_INST. the specific house on that block 🏡
• idx — the CONTEXT register offset. the exact drawer we're opening to check for clues 🔍

---

🔥 DESCRIPTION 🔥

so here's the tea: this function returns 1 if any bits were set in the *_CONTEXT_* register identified by (part, inst, idx) — which means some context was lost for that module. gone. vanished. not me checking the group chat and seeing zero messages 💀

otherwise (no bits set, everything chill), it returns 0. slay, context intact, main character module energy 👑

🫶 quick vibe check: this whole page lives at ./arch/arm/mach-omap2, dropped October 2026, and it's part of the Kernel API Manual. so if you ever forget where you found it — that's the receipt bestie 🧾

okay bye, go check those context registers, and remember: no bits set = no drama 💜🌟
