STRUCT STRATIX10_SVC_CB_DATA(9)

🎀 NAME 🎀

struct stratix10_svc_cb_data — the callback data struct that comes flying back at you from the service layer ✨ (yes this is a (9) Kernel API Manual page, we're doing kernel internals today bestie, buckle up 🦋)

💖 SYNOPSIS 💖

okay so here's the whole vibe of the struct, literally exactly as it's written:

struct stratix10_svc_cb_data {
    u32 status;
    void *kaddr1;
    void *kaddr2;
    void *kaddr3;
 };

four little members, all main character energy, no cap 💅

🌸 Members 🌸

• status — the status of the command you sent out. like, did it slay or did it flop, this field is the vibe check 🫶
• kaddr1 — the address of the 1st completed data block, or a command-specific payload, whichever fits the moment. for COMMAND_RSU_GET_DEVICE_INFO on SVC_STATUS_OK or SVC_STATUS_ERROR, this baby points to a struct arm_smccc_1_2_regs that got filled by the SMC/HVC return registers — so a0 is status, and a1–a4 are the packed device words per INTEL_SIP_SMC_RSU_GET_DEVICE_INFO 👑 and on SVC_STATUS_NO_SUPPORT (that's the older firmware that does not handle this command, sad), kaddr1 is NULL. periodt.
• kaddr2 — the address of the 2nd completed data block 😌
• kaddr3 — the address of the 3rd completed data block ⭐

💀 reminder bestie: this page lives at ./include/linux/firmware/intel, dated October 2026, and yes the man page title got truncated to struct strat..._svc_cb_data(9) which is honestly iconic of it 🙈💖

later bestie, go read your callbacks 💜🧚✨
