STRUCT DRM_PVR_DEV_QUERY_GPU_INFO(9)

okay bestie, welcome to the Kernel API Manual 💖 this page is all about struct drm_pvr_dev_query_gpu_info(9) — the container used to fetch information about the graphics processor. iconic little info-holder, honestly.

🎀 NAME 🎀

struct drm_pvr_dev_query_gpu_info — the container used to fetch information about the graphics processor. that’s literally its whole job ✨

✨ SYNOPSIS ✨

struct drm_pvr_dev_query_gpu_info {
    __u64 gpu_id;
    __u32 num_phantoms;
    __u32 _padding_c;
 };

🍓 Members 🍓

• gpu_id — GPU identifier. 💅

For all currently supported GPUs this is the BVNC encoded as a 64-bit value as follows:

┌──────────────────────────────────────┐
│     63..48   47..32   31..16   15..0 │
└──────────────────────────────────────┘
+========+========+========+=======+
|   B    |   V    |   N    |   C   |

• num_phantoms — Number of Phantoms present. 👻 (yes, capital-P Phantoms, we respect the lore)
• _padding_c — Reserved. This field must be zeroed.

🚨 reserved-field check: _padding_c must be zeroed. not a vibe, not a suggestion, just zero it, bestie.

💜 Description 💜

When fetching this type, struct drm_pvr_ioctl_dev_query_args.type must be set to DRM_PVR_DEV_QUERY_GPU_INFO_GET. that’s the assignment, no cap ✨
