💅 stmmac_tso_allocator(9) 💅

okay bestie, buckle up — this one is from the Kernel API Manual, and it's lowkey the close entry point of the driver. yes, that's the whole vibe: it's the function that closes things out. periodt.

✨ SYNOPSIS ✨

void stmmac_tso_allocator (struct stmmac_priv *priv , u32 *entry ,
       dma_addr_t des , int total_len , bool last_segment , u32 queue );

no cap, that's the whole signature — a void return because it just does the thing, no receipts, no feedback. 🫶

🎀 ARGUMENTS 🎀

  • priv — the driver private structure. it's giving main character energy, everything else lives inside it.
  • entry — TX queue buffer index. your lil pointer to where in the queue we're at 💫
  • des — buffer start address. the dma_addr_t glow-up of "where does this buffer actually live".
  • total_len — total length to fill in descriptors. literally the amount of descriptor-filling we're about to do.
  • last_segment — condition for the last descriptor. a bool, so it's a yes/no vibe check on whether this is the final one 🦋
  • queue — TX queue index. which queue we're serving, because there are many and they all want attention 😭

🌸 DESCRIPTION 🌸

this function fills descriptor and requests new descriptors according to buffer length to fill. that's it, that's the whole job. it's not doing the dramatic stuff — it's just quietly making sure the descriptors are filled and the next ones are requested, in line with how much buffer length there is to fill. iconic, honestly. 👑

and now for the friend group — this function does NOT roll alone, bestie. look at this roster:

the way this list is long long — but every single one of them is a real one, iykyk 💜

ngl, there's no scary warning section here, but do keep in mind: the only file path given in this page is ./drivers/net/ethernet/stmicro/stmmac/stmmac_main.c, and that's the one to go read if you want the lore. 🔥

okay that's the whole page, bestie — tysm for reading, drink some water 💖
