parport_ip32_set_mode(9)

💅 NAME 💅

okay so bestie, welcome to parport_ip32_set_mode(9) from the Kernel API Manual. The name is doing exactly what it says: parport_ip32_set_mode — change mode of ECP port. That's the whole assignment, and she's serving utility-function main character energy. 🎀

🦋 SYNOPSIS 🦋

the signature, character for character — do not freestyle it:

void parport_ip32_set_mode (struct parport *p , unsigned int mode );

🌸 ARGUMENTS 🌸

• p — pointer to struct parport. this is the port pointer being passed in, periodt.
• mode — new mode to write in ECR. literally the fresh mode value headed for ECR. ✨

🔥 DESCRIPTION 🔥

okay so the rundown is: ECR is reset in a sane state (interrupts and DMA disabled), and then it's placed in mode mode. If needed, it goes through PS2 mode. that's the whole flow, no cap. 💅
