irdma_invalidate_pf_hmc_pd(9)

💅 irdma_invalidate_pf_hmc_pd(9) — from the Kernel API Manual, bestie

okay so picture this: it's a Kernel API Manual page, the star of the show is irdma_invalidate_pf_hmc_pd(9), and she is here to do exactly one thing. no cap. 🎀

---

✨ NAME ✨

irdma_invalidate_pf_hmc_pd — invalidates the pd cache in the hardware for PF. that's it, that's the whole vibe. she invalidates, she leaves, she doesn't text back. 💅

---

🌸 SYNOPSIS 🌸

void irdma_invalidate_pf_hmc_pd (struct irdma_sc_dev *dev , u32 sd_idx ,
       u32 pd_idx );

literally the entire signature, character for character, no crumbs left behind 🫶. returns void — she gives nothing back and honestly? iconic.

---

🦋 ARGUMENTS 🦋

bestie, there are exactly three (3) things she needs from you, and she needs all of them:

• dev — pointer to our device struct. yes our device struct. it's giving main character energy, it's the whole device, hand her the pointer 🔥
• sd_idx — segment descriptor index. the SD one. don't mix it up with the pd one, i'm begging 🙈
• pd_idx — page descriptor index. the PD one. a different number. a different vibe. keep them straight 😭
