POWERVR VIRTUAL MEMORY HANDLING (CONSTANTS)(9)

💖 PowerVR Virtual Memory Handling (constants) 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — this is the PowerVR Virtual Memory Handling (constants) page, and it’s short but iconic ✨. like, one constant, but she’s booked and busy 💅.

🎀 PVR_IDX_INVALID 🎀

.. c:macro:: PVR_IDX_INVALID

PVR_IDX_INVALID is the default value for a u16-based index. 💖

🚨 okay, important vibe check: this value cannot be zero, because zero is a valid index value. so 0 is literally a valid index — no cap. 😭
