* gpu: nvgpu: Removal of regops from CUDA driversujeet baranwal2015-04-04
| | | | | | | | | | | | | | | | The current CUDA drivers have been using the regops to directly accessing the GPU registers from user space through the dbg node. This is a security hole and needs to be avoided. The patch alternatively implements the similar functionality in the kernel and provide an ioctl for it.

* 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.
