* gpu: nvgpu: make .tsg_unbind_channel one layer lowerRichard Zhao2018-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | The message to tell RM server to unbind channel has to be sent after client unbinds the channel and before client calls tsg release. The channel has to belong to a tsg on RM server before client submit a runlist to remove the channel. Or there's a bare channel problem. By moving .tsg_unbind_channl one layer lower, gk20a_tsg_unbind_channel() will be common functions for all chip, and it'll call tsg release after call .tsg_unbind_channel. So vgpu won't need to worry about tsg was released before sending msg to RM server.

* 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.

This change also moves the min/max bounds checking for tsg timeslice into the native function implementation. There is no sysfs node for these parameters for vgpu, as RM server is ultimately responsible for this check.
