STRUCT IPA_RESOURCE_DATA(9)

✨ NAME ✨

struct ipa_resource_data — the IPA resource configuration data 💖 like it's literally the master list of who gets what, bestie

🎀 SYNOPSIS 🎀

struct ipa_resource_data {
    u32 rsrc_group_src_count;
    u32 rsrc_group_dst_count;
    u32 resource_src_count;
    const struct ipa_resource *resource_src;
    u32 resource_dst_count;
    const struct ipa_resource *resource_dst;
 };

okay so that trailing }; with the extra space? yeah that's exactly how it shows up, we keep it, no cap 🫶

🌸 Members 🌸

• rsrc_group_src_count — how many source resource groups are supported, i.e. the source-side group headcount 📋
• rsrc_group_dst_count — same energy but for destination resource groups, this is the dst-side headcount ✨
• resource_src_count — how many entries live in the resource_src array, literally just the array length 🧮
• resource_src — the actual source endpoint group resources 🔥
• resource_dst_count — how many entries live in the resource_dst array, again just the length 💅
• resource_dst — the actual destination endpoint group resources 🌈

💜 Description 💜

So here's the tea ☕ — to manage quality of service between endpoints, certain resources that are required for operation get allocated to groups of endpoints. It's giving resource bouncer energy, honestly.

Generally this info is invisible to the AP 🙈 — like the AP doesn't even get to peek at it normally. BUT the AP is responsible for programming it at initialization time, so we specify it right here. Main character responsibility, honestly 👑.
