STRUCT IPA_QSB_DATA(9)

🌸 NAME 🌸

okay so, bestie, welcome to the Kernel API Manual page for struct ipa_qsb_data(9) — it's literally the Qualcomm System Bus configuration data struct, and it's lowkey iconic for holding the limits on how much outstanding traffic a master can have. no cap, that's the vibe 💅

✨ SYNOPSIS ✨

here's the exact shape of it, bestie — don't touch the field names, they're doing main character work:

struct ipa_qsb_data {
    u8 max_writes;
    u8 max_reads;
    u8 max_reads_beats;
 };

💅 Members 💅

• max_writes — the maximum outstanding write requests for this master, fr fr.
• max_reads — the maximum outstanding read requests for this master, periodt.
• max_reads_beats — the max outstanding read bytes, counted in 8-byte “beats” — and this one only matters if it's non-zero 🫶

🔥 SEE ALSO 🔥
