igb_cache_ring_register(9)
π igb_cache_ring_register β bestie, it's giving ring-to-register mapping β¨
So this one is from the Kernel API Manual, and it's literally about figuring out where your descriptor ring lives in register-land. No cap.
πΈ SYNOPSIS πΈ
void igb_cache_ring_register (struct igb_adapter *adapter);
Like, that's the whole signature. Short, sweet, slay.
π ARGUMENTS π
adapterβ the board private structure we're initializing. She's the main character here, okay? Everything happens through her.
π DESCRIPTION π
Okay so picture this: once we already know what feature-set is enabled for the device (iykyk, we did the vibe check earlier), we go ahead and cache the register offset that the descriptor ring is assigned to. That's it. That's the whole function. It's giving "I already know my worth and I'm just writing it down." Periodt. πββοΈ
Lowkey important: this is a caching step, bestie. We're not inventing new register offsets here β we're just remembering the one that's already been decided for this device. Don't come for me.
π¦ SEE ALSO π¦
Okay bestie, buckle up, because this list is long. Like, "how many siblings do you have" long. Every single one of these is iconic in her own right:
