STRUCT RESOURCE_TABLE(9)

✨ struct resource_table(9) — it's giving kernel API manual, section 9 💅

okay so bestie, we're in the Kernel API Manual today and the main character is literally struct resource_table. let's get into it 🫶

---

🌸 NAME 🌸

struct resource_table — the firmware resource table header. that's it, that's the vibe ✨

---

🎀 SYNOPSIS 🎀

struct resource_table {
    u32 ver;
    u32 num;
    u32 reserved[2];
    u32 offset[];
 };

no cap, that's the whole shape of it. slay 💖

---

💫 Members 💫

• ver — the version number 👑
• num — how many resource entries there are, like the headcount at the function 🔥
• reserved — reserved, and it must be zero fr fr, don't be cute with it 🙈
• offset — an array of offsets pointing at the various resource entries, lowkey the map to everything else 🗺️

🦋 Description 🦋

so a resource table is essentially a list of system resources required by the remote processor. it may also include configuration entries. and if needed, the remote processor firmware should contain this table as a dedicated ".resource_table" ELF section. periodt 💅

some resource entries are mere announcements, where the host is informed of specific remoteproc configuration. other entries require the host to do something (e.g. allocate a system resource). sometimes a negotiation is expected, where the firmware requests a resource, and once allocated, the host should provide back its details (e.g. address of an allocated memory region). it's giving group project but make it kernel 🧚

the header of the resource table, as expressed by this structure, contains a version number (should we need to change this format in the future), the number of available resource entries, and their offsets in the table. so basically a little table of contents for your table of contents, iconic honestly ⭐

immediately following this header are the resource entries themselves, each of which begins with a resource entry header (as described below). yes bestie, the entries go right after the header, in order, no gaps in the lore 🌈
