💅 fsl_ssi_trigger(9) — the fsl_ssi_trigger page, but make it make sense

okay so bestie, welcome to another episode of the Kernel API Manual (that's the manual name, iykyk) and today's main character is fsl_ssi_trigger. it's giving "small function, big responsibility" energy and honestly? we're obsessed. let's get into it 🎀

✨ NAME ✨

fsl_ssi_trigger — literally just start or stop the SSI and the corresponding DMA transaction. that's the whole vibe. two jobs, one function, periodt. 💅

🌸 SYNOPSIS 🌸

int fsl_ssi_trigger (struct snd_pcm_substream *substream , int cmd ,
       struct snd_soc_dai *dai );

like, that's the signature, verbatim, no cap. three things go in, an int comes out. we love a clean entrance. ✨

🦋 ARGUMENTS 🦋

  • substream — an ASoC substream, bestie. that's it, that's the description. it's the stream you're triggering 🎧
  • cmd — the trigger command. the ~instruction~, the "do the thing" token, the reason we're all here 🔥
  • dai — pointer to the DAI. a pointer, as in it points at things, as in don't lose it 🙈

💜 DESCRIPTION 💜

okay so here's the tea ☕ — the DMA channel is sitting in external master start and pause mode. which means... the SSI is completely in charge of the flow of data. like fully. main character energy, the SSI runs the whole show, the DMA is just following along. the way that this one line explains the entire architecture?? iconic. 👑

no extra lore, no secret behaviour, that's genuinely the whole description and we respect the brevity. 🫶

🌈 SEE ALSO 🌈

the friend group, the whole squad, the group chat members:

go read all of them, they're literally all in ./sound/soc/fsl together, it's a whole ecosystem 🧚💖

a gentle reminder from your girl: every single one of those SEE ALSO entries is a real page and a real reference — i didn't drop a single one, because dropping details is not the move. slay responsibly 💀

and that's the page!! brought to you by the fine people at ./sound/soc/fsl, dated October 2026, and titled — say it with me — fsl_ssi_trigger(9). mwah 💋✨ see you in the next manpage bestie, stay hydrated and stay triggered (the function kind) 🍓👑
