* gpu: nvgpu: Split vm_area management into vm codeAlex Waterman2017-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | The vm_reserve_va_node struct is essentially a special VM area that can be used for sparse mappings and fixed mappings. The name of this struct is somewhat confusing (as node is typically used for list items). Though this struct is a part of a list it doesn't really make sense to call this a list item since it's much more. Based on that the struct has been renamed to nvgpu_vm_area to capture the actual use of the struct more accurately. This also moves all of the management code of vm areas to a new file devoted solely to vm_area management. Also add a brief overview of the VM architecture. This should help other people follow along the hierachy of ownership and lifetimes in the rather complex MM code.

* gpu: nvgpu: Split VM implementation outAlex Waterman2017-05-19
| | | | | | | | | | | | | | | | | | | | This patch begins splitting out the VM implementation from mm_gk20a.c and moves it to common/linux/vm.c and common/mm/vm.c. This split is necessary because the VM code has two portions: first, an interface for the OS specific code to use (i.e userspace mappings), and second, a set of APIs for the driver to use (init, cleanup, etc) which are not OS specific. This is only the beginning of the split - there's still a lot of things that need to be carefully moved around.

* gpu: nvgpu: Split VM interface outAlex Waterman2017-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch begins the major rework of the GPU's virtual memory manager (VMM). The VMM is the piece of code that handles the userspace interface to buffers and their mappings into the GMMU. The core data structure is the VM - for now still known as 'struct vm_gk20a'. Each one of these structs represents one addres space to which channels or TSGs may bind themselves to. The VMM splits the interface up into two broad categories. First there's the common, OS independent interfaces; and second there's the OS specific interfaces. OS independent -------------- This is the code that manages the lifetime of VMs, the buffers inside VMs (search, batch mapping) creation, destruction, etc. OS Specific ----------- This handles mapping of buffers represented as they are represented by the OS (dma_buf's for example on Linux). This patch is by no means complete. There's still Linux specific functions scattered in ostensibly OS independent code. This is the first step. A patch that rewrites everything in one go would simply be too big to effectively review. Instead the goal of this change is to simply separate out the basic OS specific and OS agnostic interfaces into their own header files. The next series of patches will start to pull the relevant implementations into OS specific C files and common C files.

* gpu: nvgpu: Remove <linux/mm.h> from the page allocatorAlex Waterman2017-05-14
| | | | | | | | | | | | | | | | | Remove the <linux/mm.h> include from the VIDMEM page allocator. To do this PAGE_SIZE needed to be defined for VIDMEM. Technically using the Linux PAGE_SIZE macro for VIDMEM was a bug since PAGE_SIZE need not be 4K on Linux so this patch also fixes a theoretical bug. Also usage of ERR_PTR(), PTR_ERR() and IS_ERR() was removed. These are Linux specific error handling macros.
