nvme_init_lockdown(9)

💅 nvme_init_lockdown — NAME

ok so this is nvme_init_lockdown, straight out of the libnvme API manual bestie, and it's the one that initializes the passthru command for Lockdown ✨ like that's literally its whole job and it ate

🌸 SYNOPSIS

void nvme_init_lockdown (struct libnvme_passthru_cmd *cmd , __u8 scp ,
__u8 prhbt , __u8 ifc , __u8 ofi , __u8 uidx , __u8 csel , __u16 css );

no cap that's a whole lot of tiny little arguments but we're gonna go through every single one, don't worry 🫶

🎀 ARGUMENTS

• cmd — the passthru command you're gonna use. this is the main character, everything gets written into it 💖
• scp — the Scope of the command. like, how far does this thing reach 👀
• prhbt — Prohibit or allow the command opcode or Set Features command. yes it's literally "prohibit," the vowel situation is tragic but she's iconic 💅
• ifc — the Affected interface.
• ofi — Opcode or Feature Identifier. iykyk 🔥
• uidx — UUID Index, if the controller supports this id selection method. conditional queen ✨
• csel — Controller Select (CSEL): specifies which controller(s) are affected by this command, see enum nvme_lockdown_csel for the deets 🦋
• css — Controller Select Specific (CSS): the meaning is specific to csel (so it could be a Controller Identifier, a Primary Controller Identifier, or vendor specific, depends on the vibe). Ignored if csel is NVME_LOCKDOWN_CSEL_NVM_SUBSYSTEM — like literally it does not get read, periodt 💀

⭐ DESCRIPTION

Initializes the passthru command buffer for the Lockdown command. that's it, that's the whole thing, she's a one-liner and she's thriving 🌈👑

heads up bestie: css is the one that can silently do nothing depending on csel — not a bug, that's just how she's built, so don't come for me 😭
