STRUCT IPA_DATA(9)

✨ struct ipa_data(9) ✨

okay bestie, welcome to the Kernel API Manual 🎀 this one's a struct, and it's literally the combined IPA/GSI configuration data — think of it as the one big carry-all tote bag 👜 that holds all the config vibes for IPA and GSI together. no cap.

🌈 SYNOPSIS 🌈

here's the whole struct, exactly as it lives, no edits, i promise 🫶

struct ipa_data {
    enum ipa_version version;
    u32 backward_compat;
    u32 qsb_count;
    const struct ipa_qsb_data *qsb_data;
    u32 modem_route_count;
    u32 endpoint_count;
    const struct ipa_gsi_endpoint_data *endpoint_data;
    const struct ipa_resource_data *resource_data;
    const struct ipa_mem_data *mem_data;
    const struct ipa_power_data *power_data;
 };

🦋 Members 🦋

okay so each field is a whole little main character, let's meet them 💅

• version — the IPA hardware version. which generation of the hardware we're dealing with, iykyk ✨
• backward_compat — the BCR register value, and important caveat bestie: this is prior to IPA v4.5 only ⚠️ so don't come for it on newer versions.
• qsb_count — the number of entries in the qsb_data array. literally just the count, keeping tally 🔥
• qsb_data — Qualcomm System Bus configuration data. the QSB config lives here 💜
• modem_route_count — the number of modem entries in a routing table. countin' those modem routes 📋
• endpoint_count — the number of entries in the endpoint_data array. yes, another count, we stay counting 💀
• endpoint_data — IPA endpoint/GSI channel data. the endpoint + GSI channel tea ☕
• resource_data — IPA resource configuration data. all the resource config 🎀
• mem_data — IPA memory region data. memory region info, slay 🌸
• power_data — IPA power data. the power deets, iconic 👑
