via_cable_detect(9)

okay so welcome to the Kernel API Manual; today's main character is via_cable_detect(9) and she is lowkey iconic. Let's go. 💅

🌸 NAME

via_cable_detect — cable detection, but make it kernel.

✨ SYNOPSIS

int via_cable_detect (struct ata_port *ap );

🎀 ARGUMENTS

• ap — an ATA port. That's the whole vibe, bestie.

💖 DESCRIPTION

So this function performs cable detection. And actually? For the VIA case, the BIOS already did this for us — no cap. We just read the values provided by the BIOS. If you're using an 8235 in a non-PC configuration, you may need to update this code, fr fr. That's not a drill; it's an actual "go look at the code" moment.

Hotplug also impacts on this. Keep that in mind, okay? It's part of the lore, not just background noise.
