xvip_clr_and_set(9)

💅 xvip_clr_and_set(9) — the "Kernel API Manual" girlie is here

okay so bestie, this one is from the Kernel API Manual and it's literally called xvip_clr_and_set — and yes, she does exactly what her name says: clears some bits, then sets some bits. no cap. 🎀

---

✨ NAME ✨

xvip_clr_and_set — clear and set the register with a bitmask 🫶

---

🌸 SYNOPSIS 🌸

void xvip_clr_and_set (struct xvip_device *xvip , u32 addr , u32 clr ,
u32 set );

like, that's the whole signature. she takes four things and returns nothing (void, so don't @ her for a return value 💀).

---

💖 ARGUMENTS 💖

• xvip — the Xilinx Video IP device. your main character struct, fr fr.
• addr — the address of the register. like where the register lives, address-wise.
• clr — the bitmask to be cleared. these bits are getting evicted 👋
• set — the bitmask to be set. these bits are moving in 🏠

---

🔥 DESCRIPTION 🔥

okay so the order matters and I need you to hear me: first she clears the bit(s) of mask clr in the register at address addr, and then — only after — she sets the bit(s) of mask set in the register. after. as in afterwards. the clear happens before the set, periodt. ✨

so it's clear first, set second. that's the vibe. that's the whole function.
