irdma_add_sd_table_entry(9)

💖 irdma_add_sd_table_entry(9) 💖

okay bestie, welcome to the Kernel API Manual for irdma_add_sd_table_entry(9) — yes that's the whole title, and yes it's a mouthful, but we're gonna slay this together 🫶

---

✨ NAME ✨

irdma_add_sd_table_entry — adds a segment descriptor to the table. that's it, that's the vibe 💅

---

🌸 SYNOPSIS 🌸

int irdma_add_sd_table_entry (struct irdma_hw *hw , struct
irdma_hmc_info *hmc_info , u32 sd_index , enum irdma_sd_entry_type type
, u64 direct_mode_sz );

lowkey a whole signature, but we move 💀

---

🦋 ARGUMENTS 🦋

• hw — pointer to our hw struct. it's giving "the main character of the whole driver" energy, no cap 👑
• hmc_info — pointer to the HMC configuration information struct. all the config tea lives in here 🎀
• sd_index — segment descriptor index to manipulate. which one are we touching bestie, choose wisely 🙈
• type — what type of segment descriptor we're manipulating. literally the what-kind question 🌈
• direct_mode_sz — size to alloc in direct mode. like, how much room are we giving it in direct mode, that's the whole thing ⭐

ngl these are all siblings of the same irdma family and they all live in ./drivers/infiniband/hw/irdma — periodt 💀

okay that's the whole page, you ate that 🍓 and just so you have the receipts: this lil number comes from the source/version path ./drivers/infiniband/hw/irdma, dated October 2026, and it goes by irdma_add_sd_table_entry(9) — iconic, no notes 💖✨
