cdns_uart_handle_tx(9)

💅 cdns_uart_handle_tx(9) — like, the Kernel API Manual, bestie ✨

okay so welcome to the group chat, the manual name is literally cdns_uart_handle_tx(9) and it lives in the Kernel API Manual, and today we're talking about one (1) function that handles the bytes to be transmitted. that's it. that's the vibe. 🎀

🌸 NAME 🌸

cdns_uart_handle_tx — Handle the bytes to be transmitted.

like… it handles the bytes. the ones going out. the transmit girlies. periodt. 💅

---

✨ SYNOPSIS ✨

void cdns_uart_handle_tx (void *dev_id );

no cap, that's the whole signature. she takes one pointer and returns nothing. lowkey iconic of her. 🦋

---

🫶 ARGUMENTS 🫶

• dev_id — Id of the UART port. that's the one thing you pass in, bestie, and it tells the function which UART port we're talking about. don't overthink it. 💖

---

🔥 RETURN 🔥

None.

not zero, not a status code, not a little treat — None. she does the thing and leaves. main character energy fr fr. 💀

✨ bye bestie ✨ this page came from ./drivers/tty/serial, dated October 2026, and it's filed under cdns_uart_handle_tx(9) — so that's the source, the date, and the name all accounted for, slay. 🧚⭐
