💖 ppc440spe_desc_init_memcpy(9) 💖

okay so bestie, this page is straight out of the Kernel API Manual, and it's all about ppc440spe_desc_init_memcpy(9) — the function that initializes the descriptor for a MEMCPY operation. It's giving “small but important setup moment,” fr fr. 💅

🌸 NAME 🌸

ppc440spe_desc_init_memcpy — initialize the descriptor for MEMCPY operation ✨

✨ SYNOPSIS ✨

void ppc440spe_desc_init_memcpy (struct ppc440spe_adma_desc_slot *desc ,
unsigned long flags );

🎀 ARGUMENTS 🎀

• desc — -- undescribed --. The manpage is being mysterious, bestie 😭.
• flags — -- undescribed --. Same energy: no extra tea here 🫶.
