🎀 ctucan_chip_start(9) — Kernel API Manual energy 🎀

okay so bestie, we're in the Kernel API Manual and this page is literally about ctucan_chip_start(9). It's giving "kernel routine that starts the driver" and I'm obsessed. 💅

🌸 NAME 🌸

ctucan_chip_start — this routine starts the driver. periodt. 💖

✨ SYNOPSIS ✨

int ctucan_chip_start (struct net_device *ndev );

🦋 ARGUMENTS 🦋

• ndev — pointer to the net_device structure. That's the whole argument list, bestie. 🫶

💜 DESCRIPTION 💜

Okay so this routine expects that the chip is in reset state. Heads up, that part matters. ⚠️

Then it does its little main-character sequence: it sets up initial Tx buffers for FIFO priorities, sets bittiming, enables interrupts, switches the core to operational mode, and changes the controller state to CAN_STATE_STOPPED. Slay. ✨

🔥 RETURN 🔥

0 on success, and a failure value on error. no cap. 💀
