* gpu: nvgpu: Refactor page mapping codeTerje Bergstrom2015-04-04
| | | | | | | | | | | | | Pass always the directory structure to mm functions instead of pointers to members to it. Also split update_gmmu_ptes_locked() into smaller functions, and turn the hard coded MMU levels (PDE, PTE) into run-time parameters.

* gpu: nvgpu: Unify PDE & PTE structsTerje Bergstrom2015-04-04
| | | | | | | | | | Introduce a new struct gk20a_mm_entry. Allocate and store PDE and PTE arrays using the same structure. Always pass pointer to this struct when possible between functions in memory code.

| | | | | | | | | | | | | | | The GVA was increased to 128GB but for vgpu, the split was not updated to reflect the correct small and large page split (16GB for small pages, rest for large pages).
