cdns_uart_start_tx(9)

🌸 cdns_uart_start_tx(9) 🌸

okay bestie, so this page is from the Kernel API Manual — yes, the Kernel API Manual, we're in the big leagues now — and it's all about one tiny little function with main character energy: cdns_uart_start_tx. Its whole personality? Start transmitting bytes. That's it, that's the vibe. ✨

✨ NAME ✨

cdns_uart_start_tx — Start transmitting bytes 💌

---

🎀 SYNOPSIS 🎀

void cdns_uart_start_tx (struct uart_port *port );

note the void up front, bestie — this one doesn't hand anything back to you. It just does the thing and dips. 💅

---

🦋 ARGUMENTS 🦋

• port — Handle to the uart port structure 🫶 that's the one and only thing it wants from you. hand it your port handle and let it cook.

and that's the whole page!! short, sweet, and absolutely iconic 🍓 ngl a one-argument void function is such a clean little slay. anyway, this cutie lives over in ./drivers/tty/serial, and the docs say October 2026 — so yeah, future-dated manual, periodt. 💜🧚‍♀️🦋
