✨ qbman_swp_CDAN_set_context_enable(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's all about qbman_swp_CDAN_set_context_enable — yes the name is a whole mouthful, yes it's iconic, no we're not changing it. lowercase and underscored, exactly as the kernel intended 👑

🌸 NAME 🌸

qbman_swp_CDAN_set_context_enable — literally just sets the CDAN contest and enables CDAN. two jobs, one function, main character energy fr fr 💅

🎀 SYNOPSIS 🎀

int qbman_swp_CDAN_set_context_enable (struct qbman_swp *s , u16
channelid , u64 ctx );

copy it exactly like that, line break and all — do not be out here "fixing" the spacing, i'm begging 😭

🦋 ARGUMENTS 🦋

  • s — the software portal object. your swp. your little guy. 🫶
  • channelid — the index of the channel to generate CDAN. it's a u16, keep that in mind bestie.
  • ctx — i the context set in CDAN. yes that i is right there in the original and i'm not touching it, iykyk 🙈

🌈 DESCRIPTION 🌈

okay so here's the whole vibe check: this bad boy returns 0 for success, or a negative error code for failure. that's it. that's the description. short, sweet, ate and left no crumbs 🔥

so like — check the return value, bestie. 0 means slay, negative means something went sideways and you should probably go look at it 👀

⭐ SEE ALSO ⭐

the kernel file lives at ./drivers/soc/fsl/dpio/qbman-portal.h — that's the source of truth, go say hi 🌸

and here's the whole friend group, no one left behind 💜

lowkey a reminder: read the docs before you call this, bestie. the return value is not decorative 💀

okay that's the whole page, mwah 💋 this little love letter came to you from ./drivers/soc/fsl/dpio, dated October 2026 — go be iconic with your CDAN context, periodt 🧚‍♀️✨
