mpt_raid_phys_disk_pg0(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 NAME 🎀

okay bestie, this is the mpt_raid_phys_disk_pg0(9) page from the Kernel API Manual, and the main character is mpt_raid_phys_disk_pg0 — its whole iconic job is literally: returns phys disk page zero. no cap, that's the vibe. 💅

✨ SYNOPSIS ✨

the signature is giving “trust me, I know what I'm doing”:

int mpt_raid_phys_disk_pg0 (MPT_ADAPTER *ioc , u8 phys_disk_num ,
       RaidPhysDiskPage0_t *phys_disk );

💅 ARGUMENTS 💅

  • ioc — pointer to a Adapter Structure. lowkey the adapter context, bestie. 🫶
  • phys_disk_num — io unit unique phys disk num generated by the ioc. yes, “io unit unique” exactly — we don't make the rules. ✨
  • phys_disk — the requested payload data returned. so this is where the good stuff lands. 🎀

🌈 RETURN 🌈

  • 0 — on success. we love a clean return, periodt. 💖
  • -EFAULT — if the read of the config page header fails, or if the data pointer is not NULL. that's the exact caveat, bestie. 😭
  • -ENOMEM — if pci_alloc failed. sad, but at least the error code is honest. 💀

🦋 SEE ALSO 🦋

the kernel file is ./drivers/message/fusion/mptbase.c, and the whole friend group is:
