mpt3sas_port_enable_done(9)

📦 version 7.3.1, in nixpkgs unstable

💫 mpt3sas_port_enable_done — like, the port-enable completion routine, bestie 💫

okay so this is a page from the Kernel API Manual (yes, the kernel has lore too, and it's long), and today's main character is mpt3sas_port_enable_done — the command completion routine for port enable. tiny function, huge "i'm the one who finishes what _base_send_port_enable started" energy. periodt. 👑

🌸 NAME 🌸

mpt3sas_port_enable_done — the command completion routine for port enable. that's it, that's the vibe. she handles the "done!" moment. 💅

✨ SYNOPSIS ✨

u8 mpt3sas_port_enable_done (struct MPT3SAS_ADAPTER *ioc , u16 smid , u8
msix_index , u32 reply );

like, four arguments, one u8 coming back at you. no cap, she's compact. 🎀

🦋 ARGUMENTS 🦋

  • ioc — the per adapter object. yes bestie, the whole adapter, her whole world. 💖
  • smid — the system request message index. that's the little ID card your request carries around. 🪪
  • msix_index — the MSIX table index supplied by the OS. the OS literally hands you this one. 🫶
  • reply — the reply message frame (lower 32bit addr). note the exact wording: lower 32bit addr, okay, that's the address bit that matters here. 📬

⭐ RETURN ⭐

  • 1 — meaning the mf should be freed from _base_interrupt.
  • 0 — meaning the mf is freed from this function.

so basically she's like "bestie, do you want me to free it, or are you gonna handle it?" and the return value is her answer. iconic delegation honestly. 🧚

🌈 SEE ALSO 🌈

she does not travel alone, and the guest list is honestly giving family reunion. the kernel file first:

  • Kernel file ./drivers/scsi/mpt3sas/mpt3sas_base.c

and then, deep breath, everybody else:

ik that list is a lot but every single one of those little (9) icons deserves her moment, so. slay. 🔥

ngl the return-value contract is the whole point of this function. 1 means hand it off to _base_interrupt to free the mf; 0 means this function already freed it. don't mix those up, bestie, that's the kind of thing that ruins a whole afternoon. 💀

okay and for the cute sign-off 🎀 — this one lives under ./drivers/scsi/mpt3sas and the date on it is October 2026. written down in the Kernel API Manual (the mpt3sas_port_enable_done(9) page, obviously, she's the header and the footer both). bye bestie, go free that mf responsibly 💖🦋✨
