STRUCT MCHP_IPC_STATUS(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– struct mchp_ipc_status(9) πŸ’–

okay bestie, so this is a page from the Kernel API Manual and it's literally all about the IPC status message format. it's giving "small struct, big responsibilities" and honestly? we're obsessed. let's get into it 🫢


✨ NAME ✨

struct mchp_ipc_status β€” the IPC status message format, no cap. that's it, that's the vibe 🌸


✨ SYNOPSIS ✨

okay so here's the actual shape of it, copy it exactly bestie, don't be weird about it:

struct mchp_ipc_status {
    u32 status;
    u8 cluster;
 };

look at her. two members. main character energy only πŸ’…


✨ Members ✨

  • status β€” the interrupt status for all the channels associated to a cluster. every single one of them, periodt πŸ”₯
  • cluster β€” specifies the cluster instance that originated an irq. like, which cluster is this even coming from?? now u know πŸ‘‘

✨ Description ✨

so this struct is literally the one used by the SBI_EXT_IPC_STATUS SBI function id to get the message present and message clear interrupt status for all the channels associated to a cluster. that's the whole gig. she's a messenger and she slays at it πŸ’–

ngl if u were wondering "why does this exist" β€” that's why. getting that interrupt status, for every channel tied to a cluster, via that function id. iconic behavior fr fr 🌟
