STRUCT XILINX_CPM_VARIANT(9)

📦 version 7.3.1, in nixpkgs unstable

💖 struct xilinx_cpm_variant — CPM variant information 💖

okay so bestie, this is a page from the Kernel API Manual (section 9, the fun one) and it's all about struct xilinx_cpm_variant. it's giving "small struct, big responsibilities" and honestly? we stan. 🌸

✨ SYNOPSIS ✨

struct xilinx_cpm_variant {
    enum xilinx_cpm_version version;
    u32 ir_status;
    u32 ir_enable;
    u32 ir_misc_value;
 };

like, that's it. four fields. no cap. tiny little icon but she's doing the most for the Xilinx CPM PCIe controller. 🎀

🦋 Members 🦋

  • version — the CPM version, literally. it's an enum xilinx_cpm_version, so it knows what flavour of CPM it's dealing with 👑
  • ir_status — the offset for the error interrupt status register. it's a u32, it's a register offset, it's that girl. 🔥
  • ir_enable — the offset for the CPM5 local error interrupt enable register. yes specifically CPM5, yes specifically the local error interrupt enable one, don't get it twisted bestie 💅
  • ir_misc_value — a bitmask for the miscellaneous interrupt status. bitmask!! we love a bitmask 🫶

🌈 SEE ALSO 🌈

the kernel file lives at ./drivers/pci/controller/pcie-xilinx-cpm.c — that's the main character energy right there, go read it.

and the whole squad, in no particular order (okay fine, this order):

fr fr, if you're touching this struct you're gonna want all of those. it's a whole ecosystem 💜

ngl there are no options, no exit statuses, and literally zero signals on this page — it's a struct page, so the only vibe check here is "did you set your fields right". keep every offset exact or it will absolutely not slay. 😭

mwah, that's the whole page 🎀 — brought to you by ./drivers/pci/controller, dated October 2026, and signed off with a cheeky little struct xilinx_cpm_variant(9) in the corner. go be iconic with your PCIe controller, bestie 💖✨
