ENUM IWL_PRPH_SCRATCH_FLAGS(9)

✨ NAME ✨

okay so bestie, this is enum iwl_prph_scratch_flags(9) from the Kernel API Manual — it's literally the PRPH scratch control flags 💅 no cap, that's the whole vibe.

📜 SYNOPSIS 📜

here's the enum in all its main-character glory, fr fr:

enum iwl_prph_scratch_flags {
    IWL_PRPH_SCRATCH_IMR_DEBUG_EN ,
    IWL_PRPH_SCRATCH_EARLY_DEBUG_EN ,
    IWL_PRPH_SCRATCH_EDBG_DEST_DRAM ,
    IWL_PRPH_SCRATCH_EDBG_DEST_INTERNAL ,
    IWL_PRPH_SCRATCH_EDBG_DEST_ST_ARBITER ,
    IWL_PRPH_SCRATCH_EDBG_DEST_TB22DTF ,
    IWL_PRPH_SCRATCH_RB_SIZE_4K ,
    IWL_PRPH_SCRATCH_MTR_MODE ,
    IWL_PRPH_SCRATCH_MTR_FORMAT ,
    IWL_PRPH_SCRATCH_RB_SIZE_EXT_MASK ,
    IWL_PRPH_SCRATCH_RB_SIZE_EXT_8K ,
    IWL_PRPH_SCRATCH_RB_SIZE_EXT_12K ,
    IWL_PRPH_SCRATCH_RB_SIZE_EXT_16K ,
    IWL_PRPH_SCRATCH_SCU_FORCE_ACTIVE ,
    IWL_PRPH_SCRATCH_TOP_RESET

};

💅 Constants 💅

okay these are the constants, bestie — every single one, periodt:

• IWL_PRPH_SCRATCH_IMR_DEBUG_EN — IMR support for debug. slay.
• IWL_PRPH_SCRATCH_EARLY_DEBUG_EN — enable early debug conf, iconic.
• IWL_PRPH_SCRATCH_EDBG_DEST_DRAM — use DRAM, with size allocated in hwm config. no cap.
• IWL_PRPH_SCRATCH_EDBG_DEST_INTERNAL — use buffer on SRAM. lowkey.
• IWL_PRPH_SCRATCH_EDBG_DEST_ST_ARBITER — use st arbiter, mainly for multicomm.
• IWL_PRPH_SCRATCH_EDBG_DEST_TB22DTF — route debug data to SoC HW. it's giving routing.
• IWL_PRPH_SCRATCH_RB_SIZE_4K — Use 4K RB size (the default is 2K). not me defaulting to 2K 🙈
• IWL_PRPH_SCRATCH_MTR_MODE — format used for completion — 0: for completion descriptor, 1 for responses (legacy).
• IWL_PRPH_SCRATCH_MTR_FORMAT — a mask for the size of the tfd. There are 4 optional values: 0: 16 bit, 1: 32 bit, 2: 64 bit, 3: 256 bit. obsessed with options.
• IWL_PRPH_SCRATCH_RB_SIZE_EXT_MASK — RB size full information, ignored by older firmware versions, so set IWL_PRPH_SCRATCH_RB_SIZE_4K appropriately; use the below values for this. heads up, bestie 🫶
• IWL_PRPH_SCRATCH_RB_SIZE_EXT_8K — 8kB RB size.
• IWL_PRPH_SCRATCH_RB_SIZE_EXT_12K — 12kB RB size.
• IWL_PRPH_SCRATCH_RB_SIZE_EXT_16K — 16kB RB size.
• IWL_PRPH_SCRATCH_SCU_FORCE_ACTIVE — Indicate fw to set SCU_FORCE_ACTIVE upon reset. periodt.
• IWL_PRPH_SCRATCH_TOP_RESET — request TOP reset. main character energy.
