πŸ’… irdma_uk_rdma_read β€” bestie's guide to the RDMA read command πŸŽ€

okay so this page is irdma_uk_rdma_read(9) from the Kernel API Manual, and it's literally a whole vibe β€” it's the rdma read command. that's it, that's the function. short, iconic, does exactly what it says on the tin ✨ ngl it's giving "small but mighty" and i'm obsessed.


✨ SYNOPSIS ✨

here's the signature, copy it exactly bestie, no typos, we don't do that here:

int irdma_uk_rdma_read (struct irdma_qp_uk *qp , struct
       irdma_post_sq_info *info , bool inv_stag , bool post_sq );

four things go in, an int comes out. that's the whole trade, periodt πŸ’…


🫢 ARGUMENTS 🫢

gather round, let's meet the cast πŸ‘‘

  • qp β€” hw qp ptr. yeah, that's the hardware queue-pair pointer, your main character of the day. πŸ¦‹
  • info β€” post sq information. it's the post-send-queue info bundle, the little care package that tells the function what it's actually doing. πŸŽ€
  • inv_stag β€” flag for inv_stag. that's the invalidation-stag flag, it's a bool, so it's a yes-or-no vibe check. βœ…
  • post_sq β€” flag to post sq. another bool β€” do we post to the sq or not? lowkey the most important toggle in the room. πŸ”₯
no cap, both of those last two are bools, so keep them to true/false energy β€” no inventing extra values, bestie, that's not the move πŸ’€

forty entries, zero skips β€” we do not leave a single bestie out of the group chat 🫢🌸
