libnvme(9)

Okay so bestie, welcome to the libnvme(9) API Manual page for struct nvme_rate_limiting_data — the Rate Limiting Feature - Data Buffer (RLDB) struct. It's giving low-level main character energy, and we're gonna go through every single field, no skips. 💖

✨ NAME ✨

struct nvme_rate_limiting_data — Rate Limiting Feature - Data Buffer (RLDB)

🦋 SYNOPSIS 🦋

Here's the struct in all its glory, copied exactly so you can trust it fr fr:

       struct nvme_rate_limiting_data {
           __le16 rlc;
           __u8 rsvd2[5];
           __u8 bwsf;
           __le64 tbwv;
           __le64 wbwv;
           __le32 tiops;
           __le32 wiops;
           __u8 riopsr;
           __u8 wiopsr;
           __u8 rbwr;
           __u8 wbwr;
           __u8 rsvd36[476];
           __u8 vs[512];
        };
