STRUCT DRM_PVR_IOCTL_CREATE_BO_ARGS(9)

💅 struct drm_pvr_ioctl_create_bo_args(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this one's all about struct drm_pvr_ioctl_create_bo_args, and honestly? it's giving "tiny struct, big responsibilities" energy. it's the arguments bundle you hand over to %DRM_IOCTL_PVR_CREATE_BO, and we're gonna go through every field like it's a group project and you actually have to know your part 🫶

✨ SYNOPSIS ✨

like, here's the whole vibe, literally character for character:

struct drm_pvr_ioctl_create_bo_args {
    __u64 size;
    __u32 handle;
    __u32 _padding_c;
    __u64 flags;
 };

no cap, that's the entire struct. four fields. she's compact and she knows it 💅

🎀 Members 🎀

• size — [IN] the size of the buffer object you're creating. and listen: this must be page size aligned. not "roughly", not "close enough" — aligned, fr fr 🧚
• handle — [OUT] the GEM handle of the shiny new buffer object, the one you'll actually use in userspace. it's an output, so don't go stuffing your own value in there, bestie 😭
• _padding_c — reserved. this field must be zeroed. that's it. that's the whole job. zero it and move on 💀
• flags — [IN] options that affect how this creation operation behaves and future mapping operations on the object you just made (yes, it's a long-term commitment, iconic 👑). this field must be a valid combination of DRM_PVR_BO_* values, with all bits marked as reserved set to zero. so: valid combo + reserved bits zeroed. do not freestyle 🌸

⚠️ quick vibe check: _padding_c zeroed, reserved bits zeroed. the kernel is not playing about this and neither should you 💀
