ufshcd_sgl_to_prdt(9)

💖 NAME 💖

okay bestie, welcome to the ufshcd_sgl_to_prdt(9) page from the Kernel API Manual — this one is literally SG list to PRTD (Physical Region Description Table, 4DW format). no cap, that’s the whole name and it’s iconic.

✨ SYNOPSIS ✨

here’s the exact signature, do not freestyle it:

void ufshcd_sgl_to_prdt (struct ufs_hba *hba , struct ufshcd_lrb *lrbp ,
int sg_entries , struct scatterlist *sg_list );

🫶 ARGUMENTS 🫶

the cast list is giving main-character energy:

• hba — per-adapter instance. that’s the adapter context, periodt.
• lrbp — pointer to local reference block. yes, literally a pointer.
• sg_entries — The number of sg lists actually used. actually used, bestie.
• sg_list — Pointer to SG list. the SG list itself, slay.

mwah 💋 that’s the whole page, bestie. the source/version tag is ./drivers/ufs/core, it’s dated October 2026, and the manual name is still ufshcd_sgl_to_prdt(9) in case you need to cite it in the group chat. periodt.
