STRUCT PVR_FW_DEVICE_INFO_HEADER(9)

💖 struct pvr_fw_device_info_header(9) 💖

okay so this is a page from the Kernel API Manual, section 9, and it's all about struct pvr_fw_device_info_header — literally the device information header, bestie. that's it, that's the vibe. it's a little struct that tells you how big all the masks and params are. tiny, but iconic ✨

🌸 NAME 🌸

struct pvr_fw_device_info_header — the device information header, no cap 💅

---

✨ SYNOPSIS ✨

here's the whole thing, copy it exactly, don't come for me:

struct pvr_fw_device_info_header {
    u64 brn_mask_size;
    u64 ern_mask_size;
    u64 feature_mask_size;
    u64 feature_param_size;
};

four u64s and a dream 🫶

aka the group chat, member by member:

• brn_mask_size — the BRN mask size, measured in u64s. yes, in u64s, that's the unit, keep up 😌
• ern_mask_size — the ERN mask size, also in u64s. same energy, different letters 🦋
• feature_mask_size — the feature mask size. you guessed it: in u64s. consistency is slay 💖
• feature_param_size — the feature parameter size, in u64s. last one, we love a full set ⭐

ngl every single one of these is a size in u64s — so like, the number of 64-bit words, not bytes. don't mix that up or it's giving bugs 💀
