e1000e_set_pcie_no_snoop(9)

💅 e1000e_set_pcie_no_snoop

okay so bestie, welcome to the Kernel API Manual — yes, that's the whole manual name, and yes, you're gonna read this page and understand it. this one's a tiny little function from the e1000e driver family, and she's serving "one job, done well." no cap. 🎀

---

✨ NAME ✨

e1000e_set_pcie_no_snoop — literally just "Set PCI-express capabilities." that's it. that's the whole vibe. 💖

---

🌸 SYNOPSIS 🌸

void e1000e_set_pcie_no_snoop (struct e1000_hw *hw , u32 no_snoop );

notice how she returns void? she's not giving you a result, she's giving you ✨a side effect✨. main character energy fr fr.

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure 💅 this is the hardware-handle bestie, the thing you pass around so the driver knows which NIC we're talking about.
• no_snoop — bitmap of snoop events. yes queen, a bitmap — each bit is one of the events. stay with me. 🔥

---

👑 DESCRIPTION 👑

so here's the tea, bestie ☕: this function sets the PCI-express register to snoop for the events that are enabled in no_snoop. that's the description, verbatim-in-spirit, and honestly it's a whole sentence. the no_snoop bitmap is the guest list — whatever events you turned on in there get snooped at the PCI-express register. slay. 🫶

no error return, no exit status, no signals to catch — she's void, so you get zero receipts. it's giving "do the register write and ghost." 💀
