idpf_tx_splitq_build_ctb(9)
π idpf_tx_splitq_build_ctb β like, the Kernel API Manual page, bestie β¨
Okay so picture this: it's the Kernel API Manual, section 9, and today's main character is idpf_tx_splitq_build_ctb(9). Her whole personality? She populates the command tag and the size for queue based scheduling descriptors. That's it. That's the gig. And she does it flawlessly, ngl. π
β¨ NAME β¨
idpf_tx_splitq_build_ctb β populate command tag and size for queue based scheduling descriptors π¦
Like literally, she fills in the tag and the size. Iconic behavior, no notes.
πΈ SYNOPSIS πΈ
void idpf_tx_splitq_build_ctb (union idpf_tx_flex_desc *desc , struct
idpf_tx_splitq_params *params , u16 td_cmd , u16 size );
She returns void btw β no little gift back, she just does the work and leaves. Respect. π
π ARGUMENTS π
descβ the descriptor to populate, bestie. She's the canvas. The empty plate. The blank Notes app. β¨paramsβ a pointer to the tx params struct, aka the vibe source π«Άtd_cmdβ the command to be filled indesc, so like, the actual instructions going in there πsizeβ size of buffer. Yes, size matters, and yes I said it. π
π SEE ALSO π
So here's the group chat β the entire friend circle, fr fr. Actually going to list every single one because we do not leave anyone on read in this house π. And also, the kernel file herself lives at:

That's the whole contact list babe, we did not skip a single one ππ«Ά
And that's the page!! Source drop is ./drivers/net/ethernet/intel/idpf, dated October 2026 β so like, mark your calendar bestie, and remember: the girl just populates the command tag and the size. Periodt. πβ¨π
