💅 velocity_free_dma_rings(9) 💅

ok so this is a page from the Kernel API Manual, and honestly? she's a short one. a little cleanup queen. lowkey the kind of function that shows up at the end of the movie to put the chairs back. we stan a tidy icon 🎀

✨ NAME ✨

velocity_free_dma_rings — frees the PCI ring pointers, periodt 💫

✨ SYNOPSIS ✨

void velocity_free_dma_rings (struct velocity_info *vptr );

like, that's it. that's the whole signature. no cap, she takes one argument and returns void (nothing, nada, she's not giving you a return value bestie 💀).

✨ ARGUMENTS ✨

  • vptr — the Velocity you're freeing from 🦋 this is your struct velocity_info *, the main character of the whole operation. it's the thing whose rings are about to be yeeted.

✨ DESCRIPTION ✨

okay so the whole vibe here: this function cleans up the PCI ring buffers that were allocated to this velocity. 🧹✨

that's the entire job. it tidies up the ring buffers so they're not just... hanging around. the way that a good cleanup function just handles it is so iconic honestly. give her a little round of applause 👑

ngl this one's a cleanup/teardown function, so she pairs with the init side of things — you're not out here creating rings, you're releasing the ones you already made. no leaks, no drama, no cap 🙈

✨ SEE ALSO ✨

first up, the actual kernel file where all this lives:

  • ./drivers/net/ethernet/via/via-velocity.c

and now the full friend group 😭 — every single one of these is a (9) page and yes i'm listing all of them because we don't do half-finished over here:

okay that's the whole page bestie, you ate that 💅✨

cute little sign-off before you go: this lil beauty comes from the source path ./drivers/net/ethernet/via and is dated October 2026 🎀🫶 go free those rings fr fr 🌈💜
