sca3000_hw_ring_preenable(9)

okay bestie, welcome to the sca3000_hw_ring_preenable(9) page from the Kernel API Manual — buckle up 🫶💖

✨ NAME ✨

sca3000_hw_ring_preenable(9) is the hw ring buffer preenable function — that's the whole name, and yes, it's giving very specific kernel business 💅

🌸 SYNOPSIS 🌸

the signature is literally this, no cap:

int sca3000_hw_ring_preenable (struct iio_dev *indio_dev );

🎀 ARGUMENTS 🎀

• indio_dev — structure representing the IIO device. Device instance specific state can be accessed via iio_priv(indio_dev).

🦋 DESCRIPTION 🦋

okay so this is a very simple enable function ✨ the chip allows normal reads during ring buffer operation, so as long as it is indeed running before we notify the core, the precise ordering does not matter. lowkey that's the whole vibe: no extra sequencing drama, just make sure it's running and let the core know 🫶
