STRUCT DRM_PVR_CREATE_HWRT_GEOM_DATA_ARGS(9)

✨ struct drm_pvr_create_hwrt_geom_data_args(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a struct page, and honestly? it's giving "small but mighty." it's struct drm_pvr_create_hwrt_geom_data_args — the geometry data arguments used for &struct drm_pvr_ioctl_create_hwrt_dataset_args.geom_data_args. that's it, that's the whole vibe. let's get into it 🫶

🌸 SYNOPSIS 🌸

here's the shape of the thing, literally, don't touch the punctuation:

struct drm_pvr_create_hwrt_geom_data_args {
    __u64 tpc_dev_addr;
    __u32 tpc_size;
    __u32 tpc_stride;
    __u64 vheap_table_dev_addr;
    __u64 rtc_dev_addr;
 };

🎀 Members 🎀

• tpc_dev_addr — [IN] the Tail pointer cache GPU virtual address. yes, that's TPC, and yes it's a __u64. slay 💖
• tpc_size — [IN] size of TPC, in bytes. (__u32, keep up bestie 🦋)
• tpc_stride — [IN] stride between layers in TPC, in pages. pages, not bytes, don't come for me, that's what it says 💀
• vheap_table_dev_addr — [IN] VHEAP table GPU virtual address. another __u64, we love consistency ✨
• rtc_dev_addr — [IN] Render Target Cache virtual address. __u64, iconic, no notes 👑

🦋 SEE ALSO 🦋

okay this is the long part and i'm not skipping a single one, because every link here is part of the family. periodt.
