pdc_pat_pd_g...dc_revisions(9)

💖 NAME 💖

okay so bestie, this is a Kernel API Manual page for pdc_pat_pd_get_pdc_revisions — and its whole thing is literally retrieve PDC interface revisions. no cap, that's the name and the mission. ✨

🌸 SYNOPSIS 🌸

here's the exact signature, bestie — do not touch the punctuation, she's sensitive:

int pdc_pat_pd_get_pdc_revisions (unsigned long *legacy_rev , unsigned
long *pat_rev , unsigned long *pdc_cap );

lowkey iconic that the wrap happens right there, but fr fr keep it exactly like that. 💅

🎀 ARGUMENTS 🎀

okay three pointer besties walk into the function: 🌈

• legacy_rev — the legacy revision. that's it, that's the vibe. ✨
• pat_rev — the PAT revision. highkey important. 💜
• pdc_cap — the PDC capabilities. 🫶

🦋 SEE ALSO 🦋

the kernel file is ./arch/parisc/kernel/firmware.c — and then there's a whole group chat of SEE ALSO besties. peek the squad, no cap:

okay that's the page, bestie — mwah 💋. this one lives under ./arch/parisc/kernel, it's dated October 2026, and the page title is pdc_pat_pd_g...dc_revisions(9). periodt. 💖
