sdw_compute_port_params(9)

💖 sdw_compute_port_params(9) — like, the Kernel API Manual page, bestie 💖

okay so picture this: you're deep in the Kernel API Manual (yes that's the manual name, we're being official today 💅) and you've stumbled onto sdw_compute_port_params(9). It's the one that computes transport and port parameters. That's it, that's the whole vibe — it does the math so the ports and the transport know what's up. ✨

🌸 SYNOPSIS 🌸

int sdw_compute_port_params (struct sdw_bus *bus , struct
       sdw_stream_runtime *stream );

she takes two things and returns an int, no cap 🫶

🎀 ARGUMENTS 🎀

• bus — an SDW Bus instance. the bus. the whole ride. 🚌✨
• stream — the Soundwire stream. the actual audio-ish flow of data you're trying to get sorted. 🌊

not me pointing out that both of these are required — you literally cannot call this without them, so like, bring both. periodt. 💀

🦋 SEE ALSO 🦋

• the kernel file ./drivers/soundwire/generic_bandwidth_allocation.c — yes, that's the literal path, go look at the source, it's giving main character energy 👑
• is_lane_connected_to_all_peripherals(9) — the one that checks the lane situation 🌈
• sdw_compute_bus_params(9) — bus-side computing bestie 🎀
• sdw_compute_params(9) — the broader params one, the parent friend of the group chat 💜

fr fr go read the siblings above if you want the full picture, this page is a tiny slice of the lore 🧚

and that's the whole page, bestie — no bugs noted, no warnings, just a clean little helper function doing its thing. iykyk 🌸
