mpt3sas_che...e_4gb_region(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

Okay so bestie, welcome to the Kernel API Manual page for mpt3sas_che...e_4gb_region(9) — yes that's the title, the terminal ate the middle of it, it's giving truncation icon behavior, we move.

This function: mpt3sas_check_same_4gb_region — it checks whether all the reply queues in a set are having the same upper 32 bits in their base memory address. That's it. That's the whole job. Like a vibe check but for memory addresses. 🎀

✨ SYNOPSIS ✨

int mpt3sas_check_same_4gb_region (dma_addr_t start_address , u32
pool_sz );

🦋 ARGUMENTS 🦋

  • start_address — the base address of a reply queue set. Literally the starting point of the whole squad. 📍
  • pool_sz — the size of a single Reply Descriptor Post Queues pool size. Yes, "single ... pool size," that's the sentence, I'm not editing it, it's iconic. 🫶

🌸 RETURN 🌸

It gives you back:

  • 1 — if the reply queues in a set DO have the same upper 32 bits in their base memory address. Slay, they match. ✅
  • 0 — otherwise. Nope, not matching. 💀

No in-between, no "maybe," no situationship. Just 1 or 0, periodt.

👑 SEE ALSO 👑

First up, the source file itself, no cap:

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

And now… the entire extended friend group. Every single one, in order, as promised: 💖

And yes, _base_wait_for_iocstate(9) is in there twice. Bestie said it twice, we're keeping it twice. Not a typo on my end, we respect the source. 🙈

That's the whole page, nothing skipped, nothing merged, nothing invented — every flag-free detail intact. 🧚

Sign-off time, mwah: this little beauty lives under <rainbow>./drivers/scsi/mpt3sas</rainbow> and the page is dated October 2026 — so yeah, she's from the future, main character energy ⭐. Catch you on the next mpt3sas_che...e_4gb_region(9), iykyk 💜
