💖 I40E_FIND_SD_INDEX_LIMIT(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the page for I40E_FIND_SD_INDEX_LIMIT, and yeah it's a mouthful but we're gonna get through it together, i promise 🫶

✨ NAME ✨

I40E_FIND_SD_INDEX_LIMIT — finds segment descriptor index limit

like, that's literally its whole job. finding the limit. living its truth. 💅

🌸 SYNOPSIS 🌸

I40E_FIND_SD_INDEX_LIMIT (hmc_info , type , index , cnt , sd_idx ,
       sd_limit );

no cap, that's the whole call right there 👑

🎀 ARGUMENTS 🎀

six of them. six. count 'em. we're going through every single one because nobody gets left behind on my watch 😤

  • hmc_info — pointer to the HMC configuration information structure. it's giving "the big book of setup info" 📖
  • type — type of HMC resources we're searching. bestie we are looking for something and this tells us what kind of thing it is 🔍
  • index — starting index for the object. where we begin. the starting line. the origin story ✨
  • cnt — number of objects we're trying to create. how many we're making. the quantity. the amount. the count (it's in the name, i fear) 🔢
  • sd_idx — pointer to return index of the segment descriptor in question. yes it's a pointer, yes it's an out-param, yes it hands you back the index — we love a return-value moment 💫
  • sd_limit — pointer to return the maximum number of segment descriptors. a pointer that gives you back the max. the ceiling. the cap. the "that's enough bestie" number 🚫

🦋 DESCRIPTION 🦋

so what does this function actually do? it calculates the segment descriptor index and the index limit for the resource defined by i40e_hmc_rsrc_type. two things. one function. efficiency ate and left no crumbs 🔥
