STRUCT STRATIX10_SVC_CHAN(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… struct stratix10_svc_chan(9) β€” like, the service communication channel bestie πŸ’…

okay so this is a page straight out of the Kernel API Manual, and it's all about struct stratix10_svc_chan β€” the literal group chat between a service client and the service layer. pull up a chair, we're gonna read it together 🫢


✨ NAME ✨

struct stratix10_svc_chan β€” the service communication channel, no cap πŸ’–


✨ SYNOPSIS ✨

here's the whole glow-up, character for character, don't touch:

struct stratix10_svc_chan {
    struct stratix10_svc_controller *ctrl;
    struct stratix10_svc_client *scl;
    char *name;
    struct task_struct *task;
    struct kfifo svc_fifo;
    spinlock_t svc_fifo_lock;
    spinlock_t lock;
    struct stratix10_async_chan *async_chan;
 };

πŸŽ€ Members πŸŽ€

every field is a main character, let's meet them πŸ’…

  • ctrl β€” pointer to the service controller, aka the provider of this channel. she's the one paying for the venue bestie 🌸
  • scl β€” pointer to the service client that owns the channel. it's giving proprietor energy πŸ‘‘
  • name β€” the service client name tied to the channel. nameplate on the door, iconic ✨
  • task β€” pointer to the thread task that handles the SMC or HVC call πŸ”₯
  • svc_fifo β€” a queue for storing service message data, and yes it's a separate fifo for every single channel. no sharing, we don't do that here πŸ’€
  • svc_fifo_lock β€” protects access to the service message data queue (locking pending fifo). bodyguard for the fifo, obsessed πŸ¦‹
  • lock β€” protects access to the channel. the channel's very own bouncer πŸŽ€
  • async_chan β€” reference to the asynchronous channel object for this channel. the async sibling, iykyk 😭

πŸ’œ Description πŸ’œ

so this struct is what a service client uses to communicate with the service layer. literally its whole job. and here's the cute part: every service client gets its own channel, created by the service controller β€” bespoke, made-to-order, one per client 🧚 no hand-me-downs, periodt ✨


🌈 SEE ALSO 🌈

say hi to the whole extended friend group, they all live in the kernel file ./drivers/firmware/stratix10-svc.c πŸ“


ngl bestie, if you ever need the channel lifecycle functions, they're all up there in SEE ALSO. go read them, i believe in you 🫢

mwah πŸ’‹ that's the whole page, and it lives under ./drivers/firmware, dated October 2026, still serving struct stratix10_svc_chan(9) realness. slay, bye πŸŽ€βœ¨
