STRUCT DRM_PVR_DEV_QUERY_RUNTIME_INFO(9)

okay so bestie, welcome to the struct drm_...runtime_info(9) page — full name struct drm_pvr_dev_query_runtime_info — from the Kernel API Manual 💖. She's a container used to fetch information about the graphics runtime, and yes she's giving main character energy, no cap.

✨ NAME ✨

struct drm_pvr_dev_query_runtime_info — container used to fetch information about the graphics runtime. That's the whole job description, periodt 🫶.

🦋 SYNOPSIS 🦋

okay here's her exact shape, bestie — do not mess with a single type, fr fr:

       struct drm_pvr_dev_query_runtime_info {
           __u64 free_list_min_pages;
           __u64 free_list_max_pages;
           __u32 common_store_alloc_region_size;
           __u32 common_store_partition_space_size;
           __u32 max_coeffs;
           __u32 cdm_max_local_mem_size_regs;
        };

🌸 Members 🌸

every field gets her moment, lowkey:

• free_list_min_pages — Minimum allowed free list size, in PM physical pages.
• free_list_max_pages — Maximum allowed free list size, in PM physical pages.
• common_store_alloc_region_size — Size of the Allocation Region within the Common Store used for coefficient and shared registers, in dwords.
• common_store_partition_space_size — Size of the Partition Space within the Common Store for output buffers, in dwords.
• max_coeffs — Maximum coefficients, in dwords.
• cdm_max_local_mem_size_regs — Maximum amount of local memory available to a compute kernel, in dwords.

💅 Description 💅

When fetching this type, struct drm_pvr_ioctl_dev_query_args.type must be set to DRM_PVR_DEV_QUERY_RUNTIME_INFO_GET. That's the vibe check you literally cannot skip, bestie ✨.
