✨ octeon_setup_droq ✨

okay so literally welcome to the octeon_setup_droq page, bestie 💅 this is a Kernel API Manual moment and we're talking about setting up an output queue. yes. that's the whole vibe. it's giving driver-internals main character energy 🎀

🌸 NAME 🌸

octeon_setup_droq — Setup output queue 🦋

like, that's it. that's the function. it sets up the output queue. iconic of it honestly ✨

💜 SYNOPSIS 💜

int octeon_setup_droq (struct octeon_device *oct , int q_no , int
       num_descs , int desc_size , void *app_ctx );

so it returns an int (iykyk 👀), and it takes five whole arguments. five! she's thorough 💅

🫶 ARGUMENTS 🫶

okay bestie let's go through them one by one, no skipping, we don't do that here 🍓

  • oct — the octeon device. like, the actual device we're doing this to. the main character of the struct world 👑
  • q_no — which queue. gotta know which one!! pick a queue, any queue 🎀
  • num_descs — how many descriptors. the count. the amount. the number of them 💫
  • desc_size — size of each descriptor</se>... wait, size of each descriptor 📏 like how big each one is
  • app_ctx — application context. a void *, so it could be literally anything, and that's her business 🙈
ngl these descriptions are short but we are NOT dropping a single one of them. all five. every time. periodt 💀

🔥 SEE ALSO 🔥

okay so if you liked this function (and who wouldn't), here's the whole friend group 💖 first up, the kernel file where all this lives:

Kernel file ./drivers/net/ethernet/cavium/liquidio/lio_core.c

and then the squad, in order, exactly as listed, because we are not about to leave anyone out of the group chat:

eleven references. eleven. we ate and left no crumbs 🌈

💀 reminder bestie: oct is a struct octeon_device *, app_ctx is a void *, and the rest are plain old ints. keep the types exact, that's the whole point 🧚

and that's the page!! 🎀 this little drop came straight out of ./drivers/net/ethernet/cavium/... (yes it gets cut off like that, that's just how the footer does it 💅) and it's dated October 2026, so mark your calendars bestie. mwah. bye 🫶✨
