ocores_process_polling(9)

💖 NAME 💖

okay bestie, meet ocores_process_polling — it handles an IRQ-less transfer. this page is from the Kernel API Manual, and yes, the title is ocores_process_polling(9) 💅

✨ SYNOPSIS ✨

int ocores_process_polling (struct ocores_i2c *i2c );

🎀 ARGUMENTS 🎀

• i2c — your ocores I2C device instance, aka the little device baddie this call is working with 🫶

🌸 DESCRIPTION 🌸

So here's the vibe check: even if IRQ are disabled, the I2C OpenCore IP behavior is exactly the same — the only difference is that IRQ are not produced. no cap. That means we can re-use entirely ocores_isr, and we just add our polling code around it. iconic re-use moment, honestly ✨

It can run in atomic context. yes bestie, atomic context — keep that in mind 👑

⭐ RETURN ⭐

• 0 on success 🎉
• -ETIMEDOUT on timeout 😭
