ENUM IWL_FW_INI_REGION_TYPE(9)

📦 version 7.3.1, in nixpkgs unstable

🦋 enum iwl_fw_ini_region_type(9) — the Kernel API Manual glow-up 🦋

okay bestie sit down because we're looking at enum iwl_fw_ini_region_type(9) from the Kernel API Manual, and honestly? it's giving "backstage pass to the wifi firmware." this is the enum that labels what kind of region each debug region actually is. every region gets a type tag, and you're about to know all of them by heart. no cap. 💅

✨ NAME ✨

enum iwl_fw_ini_region_type — region type 🎀

like, the type of a region. that's the whole vibe. short, sweet, iconic.

};

twenty-three constants. yes we're doing all of them. grab a snack 🍓

👑 CONSTANTS 👑

okay so here's the cast of characters, member by member, and yes every single one is here because we do NOT skip anyone in this group chat:

  • IWL_FW_INI_REGION_INVALID — invalid. the "this seat is taken but also nobody's in it" of region types 🙈
  • IWL_FW_INI_REGION_TLV — uCode and debug TLVs. the ✨main character✨ TLVs.
  • IWL_FW_INI_REGION_INTERNAL_BUFFER — monitor SMEM buffer. smol but mighty.
  • IWL_FW_INI_REGION_DRAM_BUFFER — monitor DRAM buffer. the bigger sibling.
  • IWL_FW_INI_REGION_TXF — TX fifos. plural, because we contain multitudes 💅
  • IWL_FW_INI_REGION_RXF — RX fifo. singular. she's lowkey humble about it.
  • IWL_FW_INI_REGION_LMAC_ERROR_TABLE — lmac error table. when things go wrong, she's got receipts.
  • IWL_FW_INI_REGION_UMAC_ERROR_TABLE — umac error table. same energy, different co-processor 💀
  • IWL_FW_INI_REGION_RSP_OR_NOTIF — FW response or notification data. it's giving "read or unread, you decide."
  • IWL_FW_INI_REGION_DEVICE_MEMORY — device internal memory. inside thoughts, but for the device.
  • IWL_FW_INI_REGION_PERIPHERY_MAC — periphery registers of MAC. MAC said "these are my registers."
  • IWL_FW_INI_REGION_PERIPHERY_PHY — periphery registers of PHY. PHY said "same, but mine."
  • IWL_FW_INI_REGION_PERIPHERY_AUX — periphery registers of AUX. AUX is here too, don't forget AUX 🫶
  • IWL_FW_INI_REGION_PAGING — paging memory. she's doing the paging so you don't have to.
  • IWL_FW_INI_REGION_CSR — CSR registers. absolute classic. ate.
  • IWL_FW_INI_REGION_DRAM_IMR — IMR memory. not to be confused with the other DRAM one up there, iykyk.
  • IWL_FW_INI_REGION_PCI_IOSF_CONFIG — PCI/IOSF config. config queen 🔥
  • IWL_FW_INI_REGION_SPECIAL_DEVICE_MEMORY — special device memory. she has "special" in her name and honestly she earned it ⭐
  • IWL_FW_INI_REGION_DBGI_SRAM — periphery registers of DBGI SRAM. specific and unbothered.
  • IWL_FW_INI_REGION_PERIPHERY_MAC_RANGE — a range of periphery registers of MAC. more MAC registers, but as a range. multitasking icon.
  • IWL_FW_INI_REGION_PERIPHERY_PHY_RANGE — a range of periphery registers of PHY. matches the MAC range one, obviously 🌈
  • IWL_FW_INI_REGION_PERIPHERY_SNPS_DPHYIP — periphery registers of SNPS DPHYIP. yes that's really the name, yes you have to type it all out, no there's no shortcut 💜
  • IWL_FW_INI_REGION_NUM — number of region types. the responsible one who counts everybody at the end of the field trip 🧚

real talk though 🫶 — this page is literally just a type label enum, so there's nothing dangerous lurking in here. the only trap is forgetting one of the 23 constants in your own code, and that's on you, bestie.

and that's the whole page, diva. it came from ./drivers/net/wireless/intel/i..., it's dated October 2026, and it's filed under enum iwl_fw_ini_region_type(9). go forth and name your regions correctly 👑✨💖
