💅 ks_pcie_clear_dbi_mode(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: it's giving kernel-internals era, and we're in the NAME era of this page, which is literally just —

ks_pcie_clear_dbi_mode — Disable DBI mode ✨

That's it, that's the whole vibe. Short. Iconic. Main character energy.

🌸 SYNOPSIS 🌸

void ks_pcie_clear_dbi_mode (struct keystone_pcie *ks_pcie );

no return value, no drama, just vibes and a single pointer 🫶

🦋 ARGUMENTS 🦋

  • ks_pcie — a pointer to the keystone_pcie structure, which is the thing holding all the KeyStone PCIe host controller driver information. she's the keeper of the lore, fr fr 💖

✨ DESCRIPTION ✨

okay so here's the tea ☕ — modification of dbi_cs2 involves a different clock domain, which lowkey means you can't just assume the transition happened. so this function reads the status back to make sure the transition is actually complete 👑

like, no cap, it's a vibe check on your own hardware. you don't just hope it worked, you go look. periodt 💅

🧚 SEE ALSO 🧚

bestie if you're poking at DBI mode and you skip the status read-back, that's on you and the different clock domain, not on me 🙈

and that's a wrap, diva 💜 — this little number came out of ./drivers/pci/controller/dwc, October 2026, and honestly? she ate. 🌈👑
