DCONS_CROM(4)

💖 DCONS_CROM 💖 — the kernel interfaces manual, but make it cute

okay so bestie, we're talking about the dcons_crom page from the Kernel Interfaces Manual. yeah it's a section 4 situation. it's giving very niche, very firewire, very much for the girlies who debug kernels at 3am. let's get into it 🎀

✨ NAME ✨

dcons_crom — the Configuration ROM stub for dcons(4) 💅

like, it's literally a little stub. a tiny guy. but he's doing important work, okay?? 🫶

🌸 SYNOPSIS 🌸

here's the vibe, you gotta put these in your kernel config:

device dcons_crom
device dcons
device firewire

all three. yes, all three. don't skip one and then text me asking why it doesn't work 😭

🦋 DESCRIPTION 🦋

okay so here's the tea 🍓 — dcons_crom takes the buffer address of dcons(4) and exposes it through the Configuration ROM of firewire(4). like it's putting your address on the group chat so the right people can find you 💌

and who's the right people?? that address is supposed to be used by dconschat(8). that's the whole point. that's the assignment. she ate 💅✨

🌈 SEE ALSO 🌈

go read these too, i'm literally obsessed with all of them:

• dcons(4)
• firewire(4)
• fwohci(4)
• dconschat(8)
• fwcontrol(8)

shoutout to Hidetoshi Shimokawa <simokawa@FreeBSD.org> for making this whole thing happen. king behavior, no cap 👑💜

💀 BUGS 💀

okay listen. here's the one that'll get you:

if you load dcons_crom.ko manually after the system is already booted, you may have to initiate a bus reset using fwcontrol -r to update the Configuration ROM.

so basically the ROM is stuck in its old era and needs a little shake to catch up 🙈 not me forgetting the -r and then staring at the screen like 👁️👄👁️ do it manually, do it on purpose, initiate that reset, and you're golden 🧚

and that's the whole page!! this lil kernel interfaces manual entry came out of Debian on June 16, 2003 — yeah she's an elder but she still slays 💖 stay configured, stay reset, mwah 🎀✨
