STRUCT DRM_VMW_MKSSTAT_ADD_ARG(9)

💖 struct drm_vmw_mksstat_add_arg(9) 💖

okay so bestie, we're in the Kernel API Manual today and the star of the show is this lil struct, struct drm_vmw_mksstat_add_arg — say that five times fast, i dare you 😭 she's a whole vibe and she's here to be understood, so let's GO ✨

---

🌸 NAME 🌸

struct drm_vmw_mksstat_add_arg — and that's literally it, the description box is empty, she said "my name is enough" and honestly? main character energy 👑 no cap, there is nothing else on this line, do not go looking for more.

---

✨ SYNOPSIS ✨

the whole squad, laid out:

struct drm_vmw_mksstat_add_arg {
    __u64 stat;
    __u64 info;
    __u64 strs;
    __u64 stat_len;
    __u64 info_len;
    __u64 strs_len;
    __u64 description;
    __u64 id;
};

eight __u64 fields, all matching, all iconic 💅

🎀 Members 🎀

let's do a vibe check on every single one, no skipping, we don't do that here 🫶

• stat — pointer to the user-space stat-counters array. bestie, it's page-aligned, don't forget, that's not optional 🌸
• info — pointer to the user-space counter-infos array. also page-aligned, the alignment agenda is real ✨
• strs — pointer to the user-space stat strings. yep, page-aligned too, consistency queen 👑
• stat_len — length in bytes of the stat-counters array. just bytes, that's the whole thing 📏
• info_len — length in bytes of the counter-infos array. same deal, byte count only 💜
• strs_len — length in bytes of the stat strings, and lowkey the important part: terminators included. like, count those too, don't ghost them 🙈
• description — pointer to the instance descriptor string. heads up, she will be truncated to MKS_GUEST_STAT_INSTANCE_DESC_LENGTH chars — so if you wrote a whole novel, only that many chars survive, it's giving "edited for the group chat" 😭
• id — output identifier of the produced record. and if something goes wrong? it's -1. error flag, noted, respect the -1 💀

🦋 Description 🦋

literally just: this is the argument to the DRM_VMW_MKSSTAT_ADD ioctl. that's the tea ☕ that's the whole description, she's concise and we love that for her 💖

ok that's the whole page bestie, you ate that 🍓 go forth and pass those __u64s with confidence, and remember: page-aligned or it didn't happen 💅
