wx_set_interrupt_capability(9)

💅 wx_set_interrupt_capability(9) 💅

okay so this is a page from the Kernel API Manual (section 9, the kernel-API girlies) and honestly? she's a little baddie. let's get into it 🎀

---

✨ NAME ✨

wx_set_interrupt_capability — set MSI-X or MSI if supported 🦋

like, if your hardware's got the goods, she's gonna use 'em. no cap.

---

🌸 SYNOPSIS 🌸

int wx_set_interrupt_capability (struct wx *wx );

that's it. that's the whole call. one argument, returns an int. iconic minimalism 💅

---

🫶 ARGUMENTS 🫶

• wx — board private structure to initialize. this is the board's lil private struct and she's here to get it set up, bestie. the main character of the whole operation 👑

---

🌈 DESCRIPTION 🌈

so what does she actually do? she attempts — attempts, mind you — to configure the interrupts using the best available capabilities of the hardware and the kernel. 🔥

like, she's doing a vibe check on what the hardware can do and what the kernel can do, and then she's matching them up so interrupts get set up the fancy way. MSI-X, MSI… whichever one is supported. slay. ✨

that's literally the entire description. short queen energy. she doesn't over-explain. 💖

ngl bestie this one's a shorter page than the rest of the squad, but she still ate. read the whole wx_* family if you wanna actually understand the interrupt scheme, iykyk 🧚

and that's the tea 💅 this page came from ./drivers/net/ethernet/wangxun... and is dated October 2026, which — iconic queen, dropping in from the future for the wx_set_interrupt_capability(9) era. mwah 🍓💖
