🦋 SYNOPSIS 🦋

enum nvme_id_ctrl_sanicap {
    NVME_CTRL_SANICAP_CES ,
    NVME_CTRL_SANICAP_BES ,
    NVME_CTRL_SANICAP_OWS ,

    NVME_CTRL_SANICAP_NODMMAS

};

look at her. five constants. no notes. 🎀

💖 Constants 💖

okay this is the part where we go one by one, no skipping, because every single one of these matters, fr fr.

• NVME_CTRL_SANICAP_CES — Crypto Erase Support. if this is set, then the controller supports the Crypto Erase sanitize operation. slay 💅
• NVME_CTRL_SANICAP_BES — Block Erase Support. if this is set, then the controller supports the Block Erase sanitize operation. block by block, she's thorough 🧱
• NVME_CTRL_SANICAP_OWS — Overwrite Support. if this is set, then the controller supports the Overwrite sanitize operation. just write right over it, no cap 🔥
• NVME_CTRL_SANICAP_NDI — No-Deallocate Inhibited. okay listen closely because this one's got layers: if it's set and the No-Deallocate Response Mode bit is set, then the controller deallocates after the sanitize operation even if the No-Deallocate After Sanitize bit is set in a Sanitize command. yes, that's a lot of conditions. yes, all of them count. she said "read me twice" 😭
• NVME_CTRL_SANICAP_NODMMAS — No-Deallocate Modifies Media After Sanitize, mask to extract value. it's a mask, bestie. you mask it, you extract the value. that's the whole gig 🙈

lowkey reminder: these are enum constants, so you don't call them, you check them. no arguments, no return values, no exit statuses, nothing spicy. just bits doing bit things 🫶
