💖 lpfc_sli_brdready_s4(9) 💖

okay bestie, welcome to the Kernel API Manual page for lpfc_sli_brdready_s4(9) — yes, the whole page is about checking whether your sli4 host is ready, and it's lowkey iconic. 🎀

✨ NAME ✨

lpfc_sli_brdready_s4 — check for sli4 host ready status. that's the whole vibe check. 💅

🛠️ SYNOPSIS 🛠️

int lpfc_sli_brdready_s4 (struct lpfc_hba *phba , uint32_t mask );

🎀 ARGUMENTS 🎀

  • phba — pointer to the HBA context object. it's the main character context, fr fr. 🫶
  • mask — the bit mask to be checked. yes, the exact bits get inspected. 👑

💅 DESCRIPTION 💅

so this function literally checks the host status register to see if the HBA is ready. it will wait in a loop for the HBA to become ready — like refreshing the page until the server stops acting shy. 😭

if the HBA is not ready, the function resets the HBA PCI function again. yep, it hits the reset button on that PCI function.

return vibe check: 1 means the HBA failed to be ready, otherwise it returns zero. periodt. ✨
