irdma_find_sd_index_limit(9)

💖 NAME 💖

okay so bestie, this page is irdma_find_sd_index_limit(9) from the Kernel API Manual, and its whole personality is: it finds segment descriptor index limit. That’s the name, that’s the vibe, no cap. ✨

✨ SYNOPSIS ✨

void irdma_find_sd_index_limit (struct irdma_hmc_info *hmc_info , u32
       type , u32 idx , u32 cnt , u32 *sd_idx , u32 *sd_limit );

🌸 ARGUMENTS 🌸

• hmc_info — pointer to the HMC configuration information structure. it’s giving “config info main character” energy 💅
• type — type of HMC resources we’re searching. yes, we’re on the hunt 🔍
• idx — starting index for the object. the beginning of the lore 🎀
• cnt — number of objects we’re trying to create. literally the count, bestie ✨
• sd_idx — pointer to return index of the segment descriptor in question. very “which one though?” energy 🦋
• sd_limit — pointer to return the maximum number of segment descriptors. the limit, the ceiling, the final boss 👑

🦋 DESCRIPTION 🦋

This function calculates the segment descriptor index and index limit for the resource defined by irdma_hmc_rsrc_type. that’s the whole quest, and it ate. 💖
