STRUCT DRM_PVR_DEV_QUERY_QUIRKS(9)

🌸 NAME 🌸

Hiii bestie 💖 welcome to the Kernel API Manual — this page is all about struct drm_...query_quirks(9), and the actual struct name is struct drm_pvr_dev_query_quirks. It’s the container used to fetch information about hardware fixes for which the device may require support in the user mode driver. Slay. ✨

---

🦋 SYNOPSIS 🦋

struct drm_pvr_dev_query_quirks {
    __u64 quirks;
    __u16 count;
    __u16 musthave_count;
    __u32 _padding_c;
};

---

🎀 Members 🎀

• quirks — a userspace address for the hardware quirks __u32 array.

The first musthave_count items in the list are quirks that the client must support for this device. If userspace does not support all these quirks then functionality is not guaranteed and client initialisation must fail. 🫠 This one is serious, bestie — not a vibe, an actual requirement.

The remaining quirks in the list affect userspace and the kernel or firmware. They are disabled by default and require userspace to opt-in. The opt-in mechanism depends on the quirk. 💅

• count — length of quirks (number of __u32).
• musthave_count — the number of entries in quirks that are mandatory, starting at index 0. 👑
• _padding_c — reserved. This field must be zeroed. 🚨

---

✨ Description ✨

When fetching this type, struct drm_pvr_ioctl_dev_query_args.type must be set to DRM_PVR_DEV_QUERY_QUIRKS_GET. Periodt. 💖
