STRUCT STRATIX10_SVC_SH_MEMORY(9)

💅 struct stratix10_svc_sh_memory 💅

okay bestie, welcome to the Kernel API Manual ✨ this page is all about struct stratix10_svc_sh_memory — the service shared memory structure. it’s giving very specific kernel lore, and we’re gonna get into it. 🫶

🌸 NAME 🌸

struct stratix10_svc_sh_memory — service shared memory structure. periodt. 💖

✨ SYNOPSIS ✨

       struct stratix10_svc_sh_memory {
           struct completion sync_complete;
           unsigned long addr;
           unsigned long size;
           svc_invoke_fn *invoke_fn;
        };

• sync_complete — state for a completion. literally that’s the whole vibe. ✅
• addr — physical address of shared memory block. the actual location, no cap. 📍
• size — size of shared memory block. how much room we’re working with, bestie. 📏
• invoke_fn — service clients to handle secure monitor or hypervisor calls. this is the hookup for those calls. 🔌

🎀 Description 🎀

This struct is used to save the physical address and size of a shared memory block. The shared memory block (yes, the manpage says “blocked” — we move 💀) is allocated by secure monitor software at secure world.

The service layer driver uses that physical address and size to create a memory pool, then allocates a data buffer from that memory pool for the service client. it’s giving infrastructure realness. 🔥
