cxgb4_sched_class_alloc(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… cxgb4_sched_class_alloc(9) β€” okay bestie, let's talk scheduling classes

So this one lives in the Kernel API Manual, which is giving very "backstage pass to the kernel" energy, and honestly? Iconic. It's a kernel API page about grabbing yourself a scheduling class in the cxgb4 driver. Let's get into it πŸŽ€


✨ NAME ✨

cxgb4_sched_class_alloc β€” allocate a scheduling class, fr fr 🌸


πŸ¦‹ SYNOPSIS πŸ¦‹

struct ch_sched_class * cxgb4_sched_class_alloc (struct net_device *dev
, struct ch_sched_params *p );

Like, it takes two things and hands you back a struct ch_sched_class *. Periodt. πŸ’…


πŸ“ ARGUMENTS πŸ“

  • dev β€” a net_device pointer. Just your net device, bestie, nothing chaotic 🌈
  • p β€” the new scheduling class you wanna create ✨

πŸ‘‘ DESCRIPTION πŸ‘‘

Okay so the way this works: it returns a pointer to the scheduling class that got created πŸ”₯

And there's two lil scenarios, iykyk:

  • If p is NULL, then it allocates and returns any available unused scheduling class. Like, "surprise me, give me whatever's free" energy πŸ™ˆ
  • If a scheduling class with a p that matches is found, then that matching class is the one that gets returned 🫢

Either way you walk away with a class. Slay πŸ’–

Heads up bestie β€” keep those two behaviours straight, because they're lowkey different paths to your answer, and the manpage is very clear that a NULL p means "any unused one" while a matching p means "that specific match." No cap 🧚

Okay that's the whole page, mwah πŸ’‹ β€” this one came from ./drivers/net/ethernet/chelsio... and it's dated October 2026, and the page itself is cxgb4_sched_class_alloc(9). Go forth and allocate responsibly, main character πŸ¦‹πŸ’œ
