ENUM IWL_CONTEXT_INFO_FLAGS(9)

🎀 enum iwl_context_info_flags(9) — the Kernel API Manual, bestie edition 🎀

Okay so welcome to the glow-up of enum iwl_context_info_flags(9) — literally the handbook for Context information control flags 💅 this is the little enum that tells the firmware how to behave, and we're gonna read it together like it's a group chat 🫶

✨ NAME ✨

enum iwl_context_info_flags — Context information control flags 🎀 no cap, that's the whole vibe: these are the flags that control the context info block.

};

Like, look at her. Sixteen members, all present, all accounted for, nothing skipped 👑🔥

🦋 Constants 🦋

Bestie, here's the tea on every single one of them — same facts, just with the personality they deserve 💖

• IWL_CTXT_INFO_AUTO_FUNC_INIT — when this one's set, the FW will not wait before interrupting the init done for the driver command that configures several system modes ✨ (yes, exactly that sentence's meaning, just said with feeling).
• IWL_CTXT_INFO_EARLY_DEBUG — enable early debug 🐛💜
• IWL_CTXT_INFO_ENABLE_CDMP — enable core dump 💀 (the literal core dump, not the slang one, though honestly both apply).
• IWL_CTXT_INFO_RB_CB_SIZE — this is the mask of the RBD Cyclic Buffer Size exponent. The actual size is 2**value, valid sizes are 8-2048. The value is four bits long. Maximum valid exponent is 12 ⭐ (do not come for her with exponent 13, she will simply not).
• IWL_CTXT_INFO_TFD_FORMAT_LONG — use long TFD Format. The default is short format — and heads up, short format is not supported by the driver 🙈 so this one's lowkey mandatory energy.
• IWL_CTXT_INFO_RB_SIZE — the RB size mask, and the values are IWL_CTXT_INFO_RB_SIZE_*K 🎀
• IWL_CTXT_INFO_RB_SIZE_1K — Value for 1K RB size
• IWL_CTXT_INFO_RB_SIZE_2K — Value for 2K RB size
• IWL_CTXT_INFO_RB_SIZE_4K — Value for 4K RB size
• IWL_CTXT_INFO_RB_SIZE_8K — Value for 8K RB size
• IWL_CTXT_INFO_RB_SIZE_12K — Value for 12K RB size
• IWL_CTXT_INFO_RB_SIZE_16K — Value for 16K RB size
• IWL_CTXT_INFO_RB_SIZE_20K — Value for 20K RB size
• IWL_CTXT_INFO_RB_SIZE_24K — Value for 24K RB size
• IWL_CTXT_INFO_RB_SIZE_28K — Value for 28K RB size
• IWL_CTXT_INFO_RB_SIZE_32K — Value for 32K RB size 🌈

Ngl, the whole 1K → 32K run is giving "collect them all" and honestly? We love a complete set 💅
