pdc_pci_irt_size(9)

🎀 NAME 🎀

hey bestie, welcome to the pdc_pci_irt_size(9) page in the Kernel API Manual — this one is short, sweet, and lowkey iconic. 💅

pdc_pci_irt_size — Get the number of entries in the interrupt routing table. periodt.

---

✨ SYNOPSIS ✨

the signature is giving very C, very demure:

int pdc_pci_irt_size (unsigned long *num_entries , unsigned long hpa );

---

💅 ARGUMENTS 💅

• num_entries — The return value. that's the whole assignment, bestie 🫶
• hpa — The HPA for the device. no notes, no cap.

---

🌸 DESCRIPTION 🌸

okay so this PDC function returns the number of entries in the specified cell's interrupt table. that's it, that's the tea ☕✨

It's similar to PDC_PAT stuff — but it was added for Forte/Allegro boxes. iykyk 🧚
