* 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.

| | | | | | | | | | | | | | | | | | Decrement the ref count on all mapped_buffers belonging to a va_node when a va_node is freed. This prevents userspace from leaking some mapped_buffers in some cases.

* gpu: nvgpu: make larger address space workAlex Waterman2015-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement several fixes for allowing the GVA address space to grow to larger than 32GB and increase the address space to 128GB. o Implement dynamic allocation of PDE backing pages. The memory to store the PDE entries was hard coded to 1 page. Now the number of pages necessary is computed dynamically based on the size of the address space and the size of large pages. o Fix an arithmetic problem in the gm20b sparse texture code that caused large address spaces to be truncated when sparse PDEs/PTEs were being filled in. This caused a kernel panic when freeing the address space since a lot of the backing PTE memory was not allocated. o Change the address space split for large and small pages. Small pages now occupy the bottom 16GB of the address space. Large pages are used for the rest of the address space. Now, with a 128GB address space, there are 112GB of large page GVA available. This patch exists to allow large (16GB) sparse textures to be allocated without running into lack of memory issues and kernel panics.

* gpu: nvgpu: Use pgsz_idx instead of page_sizeTerje Bergstrom2015-03-18
| | | | | | | | | | | | | Alloc space writes the page size to a field that requires pgsz_idx. That can cause corruption in internal kernel structures. Clear_sparse treated a parameter as page size instead of index.
