pvr_gem_object_vunmap(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

Okay bestie, this is the Kernel API Manual page for pvr_gem_object_vunmap(9), and it's literally about unmapping a PowerVR memory object from CPU virtual address space. Group-chat summary: short function, one argument, one CPU-cache plot twist. πŸ’…

πŸŽ€ NAME πŸŽ€

pvr_gem_object_vunmap β€” unmap a PowerVR memory object from CPU virtual address space. Slay. ✨

✨ SYNOPSIS ✨

void pvr_gem_object_vunmap (struct pvr_gem_object *pvr_obj );

Return type is void, so there's no return value to obsess over β€” it just does the unmap. πŸ’…

πŸ¦‹ ARGUMENTS πŸ¦‹

  • pvr_obj β€” target PowerVR GEM object. The main character of this call, no cap. πŸ’–

🌸 DESCRIPTION 🌸

If pvr_obj is CPU-cached, dma_sync_sgtable_for_device is called to make sure the GPU mapping is consistent.

That's the whole plot: CPU-cached object in, sync call happens, GPU mapping stays consistent. Periodt. ✨
