🎀 Constants 🎀

Okay so here's the whole squad — every constant in the enum, no cap, nothing skipped 👑

💫 The shift amounts

These are the shift amounts, i.e. how far you gotta slide the bits over to actually get the thing. Iconic little offsets fr fr.

• NVME_CSTS_RDY_SHIFT — shift amount to get the ready ✨
• NVME_CSTS_CFS_SHIFT — shift amount to get the controller fatal status 😭
• NVME_CSTS_SHST_SHIFT — shift amount to get the shutdown status 🦋
• NVME_CSTS_NSSRO_SHIFT — shift amount to get the NVM subsystem reset occurred 💀
• NVME_CSTS_PP_SHIFT — shift amount to get the processing paused 🙈
• NVME_CSTS_ST_SHIFT — shift amount to get the shutdown type ⭐

🧚 The masks

And these are the masks — the ones that do the actual picking-out of the bits. Mask + shift = the moment, iykyk 💖

• NVME_CSTS_RDY_MASK — mask to get the ready ✨
• NVME_CSTS_CFS_MASK — mask to get the controller fatal status 😭
• NVME_CSTS_SHST_MASK — mask to get the shutdown status 🦋
• NVME_CSTS_NSSRO_MASK — mask to get the NVM subsystem reset occurred 💀
• NVME_CSTS_PP_MASK — mask to get the processing paused 🙈
• NVME_CSTS_ST_MASK — mask to get the shutdown type ⭐

🌈 The shutdown-status vibes

Three moods of the shutdown status field, and honestly they ate:

• NVME_CSTS_SHST_NORMAL — normal operation 👑
• NVME_CSTS_SHST_OCCUR — shutdown processing occurring 🔥
• NVME_CSTS_SHST_CMPLT — shutdown processing complete 🎀
