💅 idpf_mmio_region_non_static — a kernel API manual moment

okay so bestie, we're in the Kernel API Manual today and the star of the show is idpf_mmio_region_non_static(9). It's a tiny little bool-returning bestie whose whole personality is "is this region not static? 👀" Let's get into it 💖

✨ NAME ✨

idpf_mmio_region_non_static — check if region is not static ✨

That's it. That's the whole job. She checks, she returns a bool, she leaves. Iconic behavior ngl 🎀

🌸 SYNOPSIS 🌸

bool idpf_mmio_region_non_static (struct libie_mmio_info *mmio_info ,
       struct libie_pci_mmio_region *reg );

Look at her, two whole args, returning bool. lowkey a legend 🌈

🎀 ARGUMENTS 🎀

  • mmio_info — PCI resources info 🫶 this is the one carrying all the resource deets
  • reg — the region to check 💅 this is the actual region we're vibe checking

Two args, no notes. Slay.

🦋 RETURN 🦋

  • true — if the region can be received though the virtchnl command 🔥 (yes bestie, the region is reachable that way)
  • false — if the region is related to mailbox or resetting 😭 those ones do NOT go through the virtchnl path

So like, the whole function is basically a little bouncer at the club door: true means "you're on the virtchnl list, come on in 🪩", false means "bestie you're with the mailbox/reset crowd, wrong door." No cap. 💀

🔥 SEE ALSO 🔥

okay so this section is HUGE — the whole idpf virtchnl friend group came to the party. Every single one of them, in order 🫶:

And the source file where the magic lives 🧚:

./drivers/net/ethernet/intel/idpf/idpf_virtchnl.c

(yes, the same directory also shows up as ./drivers/net/ethernet/intel/idpf down at the bottom — that's the whole squad's home base 🏠)

bestie reminder: every one of those refs is (9), so they're all kernel API pages. Go read them if you're nosy. iykyk 💜
