lpfc_sli4_write_eq_db(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

okay bestie, welcome to lpfc_sli4_write_eq_db(9) from the Kernel API Manual β€” it's giving "tiny doorbell function, huge responsibility" energy πŸ’…βœ¨

πŸ’– NAME πŸ’–

lpfc_sli4_write_eq_db β€” write EQ DB for eqe's consumed or arm state πŸŽ€

✨ SYNOPSIS ✨

       void lpfc_sli4_write_eq_db (struct lpfc_hba *phba , struct lpfc_queue *q
       , uint32_t count , bool arm );

🌸 ARGUMENTS 🌸

bestie, here's the cast of characters, no cap:

  • phba β€” the adapter with the EQ πŸ’–
  • q β€” The Event Queue that the host has completed processing for. the host is done with it, so we're telling on ourselves 🫢
  • count β€” Number of elements that have been consumed. literally the count, iykyk πŸ”’
  • arm β€” Indicates whether the host wants to arms this CQ. yes, the page says CQ, and we are keeping the wording exactly πŸ’…

πŸ¦‹ DESCRIPTION πŸ¦‹

This routine will notify the HBA, by ringing the doorbell, that count number of EQEs have been processed. πŸ”” The arm parameter indicates whether the queue should be rearmed when ringing the doorbell. that's the whole vibe: processed stuff gets announced, and arm says whether we rearm on the way out. periodt ✨

πŸ‘‘ SEE ALSO πŸ‘‘

okay so the SEE ALSO section is a whole group chat β€” I'm putting it exactly as listed so none of the references get left on read 😭🫢
