* gpu: nvgpu: Move TSG IOCTL code to Linux moduleTerje Bergstrom2017-04-04
| | | | | | | | | | | | | | | | Move TSG IOCTL specific code to Linux module. This clears most Linux dependencies from tsg_gk20a.c. Move also remaining file_operations declarations from channel_gk20a.h to ioctl_channel.h.

* gpu: nvgpu: Abstraction for *sleep, *delayAlex Waterman2017-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | Add abstractions for the following: msleep() udelay() usleep_range() These functions are only a subset of the available Linux delay and sleep functions but this seems to be what we use and what is actually useful for driver development.

* gpu: nvgpu: Split as code to as IOCTL and commonTerje Bergstrom2017-04-02
| | | | | | | | | | | | | | | | | | Split as_gk20a.c into two parts: common/linux/ioctl_as.c deals with as related devnodes and ioctls. This file contains all the Linux specific parts of as_gk20a.c. common/as.c deals with general as_gk20a maintenance and is Linux independent.

* gpu: nvgpu: drop 0x in front of timed out symbolKonsta Holtta2017-03-07
| | | | | | | | | | | | | | | The Linux timer code prints an error message containing the caller when a timeout happens. The caller is formatted as a function name instead of a pointer, so don't print 0x in front of it.

* gpu: nvgpu: kmem abstraction and trackingAlex Waterman2017-03-03
| | | | | | | | | | | | | | | | Implement kmem abstraction and tracking in nvgpu. The abstraction helps move nvgpu's core code away from being Linux dependent and allows kmem allocation tracking to be done for Linux and any other OS supported by nvgpu.

* gpu: nvgpu: Move kmem_caches to allocatorAlex Waterman2017-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using a single static kmem_cache for each type of data structure the allocators may want to allocate each allocator now has its own instance of the kmem_cache. This is done so that each GPU driver instance can accurately track how much memory it is using. In order to support this on older kernels a new NVGPU API has been made, nvgpu_kmem_cache_create(struct gk20a *g, size_t size) To handle the possibility that caches cannot be created with the same name. This patch also fixes numerous places where kfree() was wrongly used to free kmem_cache allocs.

* gpu: nvgpu: Add timeout APIAlex Waterman2016-12-05
Add a timeout API to nvgpu since this is a common operation done all across the nvgpu driver. Also add two new directories for this common code: drivers/gpu/nvgpu/common drivers/gpu/nvgpu/include/nvgpu The common directory is for common C code. The include directory is for common include files.
