💅 adm_process_fc_descriptors(9) — the Kernel API Manual glow-up 🦋

okay so bestie, welcome to the adm_process_fc_descriptors(9) page from the Kernel API Manual. yes it's a mouthful, yes we're gonna get through it together, and yes it's literally about processing descriptors for flow controlled xfers. slay. 💖

✨ NAME ✨

adm_process_fc_descriptors — process descriptors for flow controlled xfers. that's the whole vibe. no cap. 🎀

🌸 SYNOPSIS 🌸

void * adm_process_fc_descriptors (struct adm_chan *achan , void *desc ,
struct scatterlist *sg , u32 crci , u32 burst , enum
dma_transfer_direction direction );

look at her. six arguments, one return type, main character energy only. 👑

🌈 ARGUMENTS 🌈

  • achan — the ADM channel, bestie. that's your whole context right there. 🫶
  • desc — descriptor memory pointer. it's giving "pointer to the memory where the descriptor lives". 💫
  • sg — scatterlist entry. yes queen, one entry. 🌸
  • crci — the CRCI value. iconic, mysterious, exactly as advertised. ⭐
  • burst — burst size of transaction. it's literally the burst size of the transaction. 🔥
  • direction — DMA transfer direction. which way are we going? that. 🧭

🦋 SEE ALSO 🦋

kernel file ./drivers/dma/qcom/qcom_adm.c, and honestly the whole friend group:

go read all of them, iykyk. 💜

ngl, the non_fc one is right there in the list and she is not the same function — don't mix them up, bestie. 🙈

okay that's the whole page and you ate it. 🍓 this lil number lives in ./drivers/dma/qcom and it's dated October 2026. mwah, bye, go write some descriptors. 💅✨
