ti_sci_cmd_...ap_tx_ch_cfg(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ti_sci_cmd_rm_udmap_tx_ch_cfg — bestie's guide to the Kernel API Manual 🎀

okay so this is from the Kernel API Manual, and yes the page header is like ti_sci_cmd_...ap_tx_ch_cfg(9) because apparently we're too iconic for full filenames in headers 💀. Anyway. Sit down, grab a lil snack 🍓, we're configuring a UDMAP TX channel and it's gonna be so chill.

✨ NAME ✨

ti_sci_cmd_rm_udmap_tx_ch_cfg — configure a UDMAP TX channel 🦋

Like. That's literally the whole vibe. You're setting up a transmit channel, bestie, and the kernel is gonna help you do it.

🌸 SYNOPSIS 🌸

int ti_sci_cmd_rm_udmap_tx_ch_cfg (const struct ti_sci_handle *handle ,
const struct ti_sci_msg_rm_udmap_tx_ch_cfg *params );

so it takes two pointers and hands you back an int. no cap, that's it. 🫶

🎀 ARGUMENTS 🎀

  • handle — pointer to the TI SCI handle. this is your main character pointer, the one that knows who you are and what firmware you're talking to 💫
  • params — pointer to the ti_sci_msg_rm_udmap_tx_ch_cfg TX channel config structure. this is where you actually put the TX channel settings, like the whole lil outfit for your channel 👑

⭐ RETURN ⭐

0 if all went well 💖 — else it returns the appropriate error value 😭 (so like, check it. fr fr. checking is free.)

🌈 DESCRIPTION 🌈

highkey there's not a ton of prose here, bestie — the page just says:

See ti_sci_msg_rm_udmap_tx_ch_cfg and ti_sci_msg_rm_udmap_tx_ch_cfg_req for more info.

and honestly? go read those two, they're the ones holding all the actual lore iykyk 📚✨

💜 SEE ALSO 💜

okay so this list is LONG and it ate, no notes 👑

  • Kernel file ./drivers/firmware/ti_sci.c

and then the whole friend group 💅:

like I said. the whole group chat. 🫶

💀 reminder bestie: read the ti_sci_msg_rm_udmap_tx_ch_cfg and ti_sci_msg_rm_udmap_tx_ch_cfg_req pages before you start poking at channel config, they're the ones with the actual field details and this page just points at them 🧚

okay and finally the cute sign-off 💌 this one lives in ./drivers/firmware, the manual's dated October 2026, and the page title on the way out is literally ti_sci_cmd_...ap_tx_ch_cfg(9) again — yes it's truncated, yes it's still iconic, we love a consistent queen 👑✨ bye bestie, go configure that TX channel 🌸
