snd_pdacf_assign_resources(9)

💖 NAME 💖

snd_pdacf_assign_resources — bestie, this is the one that boots the card up and sets the whole instance into motion. It initializes the hardware and the card instance, like, both of them, at once, iconic behaviour honestly.

(it lives in section 9 of the Kernel API Manual, in case u were wondering where to find it 💅)

✨ SYNOPSIS ✨

int snd_pdacf_assign_resources (struct snd_pdacf *pdacf , int port , int
irq );

🎀 ARGUMENTS 🎀

• pdacf — the context, aka the whole vibe of the thing, it's the struct snd_pdacf * u pass in 🫶
• port — the i/o port for the card, like the literal address bestie
• irq — the irq number for the card, the interrupt line it gets to call home 🌸

🦋 DESCRIPTION 🦋

okay so real talk, here's what this function does, no cap:

• it assigns the port and irq u specified ✨
• it boots the card 🔥
• it creates the pcm and control instances 🎀
• and it initializes the rest of the hardware 💜

it returns 0 if everything slayed, or a negative error code if it did not. so like, check that return value, i'm begging 😭

heads up: a return of 0 means success. anything negative is a no. don't be out here treating a negative value as a win, that's not the vibe check passing 💀
