mpi3mr_cfg_get_sas_exp_pg0(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

Okay bestie, welcome to the Kernel API Manual entry for mpi3mr_cfg_get_sas_exp_pg0 — yes that's a mouthful, but it's literally the function that reads the current SAS Expander page 0. That's the whole vibe. 💅

🦋 SYNOPSIS 🦋

Okay so here's the signature, and yes it's a lot of arguments, but we love her:

       int mpi3mr_cfg_get_sas_exp_pg0 (struct mpi3mr_ioc *mrioc , u16
       *ioc_status , struct mpi3_sas_expander_page0 *exp_pg0 , u16 pg_sz , u32
       form , u32 form_spec );

🎀 ARGUMENTS 🎀

  • mrioc — Adapter instance reference. Like, the adapter's whole identity. 🫶
  • ioc_status — Pointer to return ioc status. It's where the status comes back to, no cap. ☕
  • exp_pg0 — Pointer to return SAS Expander page 0. The page herself. 🌸
  • pg_sz — Size of the memory allocated to the page pointer. Important! It's the size check for the memory you allocated to the page pointer. 💀
  • form — The form to be used for addressing the page. Address it, bestie! 🎀
  • form_spec — Form specific information like device handle. The little details that slay. ✨

💅 DESCRIPTION 💅

Okay so listen up: this function is the handler for config page read for a specific SAS Expander page0. That's its whole job. Periodt. 💅

The ioc_status has the controller returned ioc_status. That means the controller's status comes back through that pointer, and you're gonna want to look at it. But here's the tea, and I need you to sip it slowly: this routine doesn't check ioc_status to decide whether the page read is a success or not — and it is the caller's responsibility. That's right, bestie, it's not gonna hold your hand. You have to check it yourself. No cap. 🙈

⚠️ Warning: mpi3mr_cfg_get_sas_exp_pg0 literally does not check ioc_status to decide success. If you don't check it, that's on you. The caller is responsible. Periodt. 💀

🌈 RETURN 🌈

Returns 0 on success, non-zero on failure. So if you see 0, slay. If not, something's up. 😭
