💖 mpi3mr_map_eedp_error — Map EEDP errors from IOC status ✨

okay so this is a page from the Kernel API Manual, section 9, and it is so specific and I love that for us. it's about one tiny little function in the mpi3mr driver that does one tiny little job, and honestly? iconic. let's get into it 🫶

🌸 NAME 🌸

mpi3mr_map_eedp_error — Map EEDP errors from IOC status. that's the whole vibe. it maps, it's EEDP, it's an error thing. periodt.

✨ SYNOPSIS ✨

void mpi3mr_map_eedp_error (struct scsi_cmnd *scmd , u16 ioc_status );

look at that signature bestie, it returns void so don't go expecting a little return value treat, there isn't one 🎀

🦋 ARGUMENTS 🦋

  • scmd — a SCSI command reference. yes, that SCSI command. the one you're dealing with. 💅
  • ioc_status — the status of the MPI3 request. it's a u16, it's the status, it's giving "here's what the IOC thinks happened". 🔥

🧚 DESCRIPTION 🧚

so what does this little function actually do? it maps the EEDP error status of the SCSI IO request to sense data. that's it. that's the whole job. no cap, it takes the EEDP error situation and turns it into sense data so the rest of the stack can understand what went down. lowkey important, highkey underrated. ⭐

EEDP = the error-detection/protection stuff. the function's entire personality is "translate this for me please" and honestly same 💀

🌈 RETURN 🌈

Nothing. literally nothing. it returns void, so like… don't wait up for a value, babe. 😭 it did the mapping and it left. main character energy, zero follow-up. 👑

🍓 SEE ALSO 🍓

the kernel file lives right here — go peek at it if you're nosy (affectionate):

  • ./drivers/scsi/mpi3mr/mpi3mr_os.c

and here's the whole extended friend group, in the order the manual lists them 💜:

like, that's a lot of friends. ninety-something of them. they all showed up to the group chat. iykyk 💅

and that's the whole page bestie 🎀 this cutie dropped from ./drivers/scsi/mpi3mr back in October 2026 — go read the whole mpi3mr family, they ate. mwah 💋 ✨
