* gpu: nvgpu: move clk_arb to linux specificMahantesh Kumbar2017-10-25
| | | | | | | | | | | | | | | | | - Clock arbiter has lot of linux dependent code so moved clk_arb.c to common/linux folder & clk_arb.h to include/nvgpu/clk_arb.h, this move helps to unblock QNX. - QNX must implement functions present under clk_arb.h as needed.

* gpu: nvgpu: Fix race in PMU state transitions.Deepak Goyal2017-10-25
| | | | | | | | | | | | | | | | | | | | | PMU response(intr callback for messages) can run faster than the kthread posting commands to PMU. This causes the PMU message callback to skip important pmu state change(which happens just after the PMU command is posted). Solution: State change should be triggered from only inside the intr callback. Other places can only update the pmu_state variable. This change also adds error check to print in case command post fails.

* gpu: nvgpu: Begin reorganizing VM mapping/unmappingAlex Waterman2017-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move vm_priv.h to <nvgpu/linux/vm.h> and rename nvgpu_vm_map() to nvgpu_vm_map_linux(). Also remove a redundant unmap function from the unmap path. These changes are the beginning of reworking the nvgpu Linux mapping and unmapping code. The rest of this patch is just the necessary changes to use the new map function naming and the new path to the Linux vm header. Patch Series Goal ----------------- There's two major goals for this patch series. Note that these goals are not achieved in this patch. There will be subsequent patches. 1. Remove all last vestiges of Linux code from common/mm/vm.c 2. Implement map caching in the common/mm/vm.c code To accomplish this firstly the VM mapping code needs to have the struct nvgpu_mapped_buf data struct be completely Linux free. That means implementing an abstraction for this to hold the Linux stuff that mapped buffers carry about (SGT, dma_buf). This is why the vm_priv.h code has been moved: it will need to be included by the <nvgpu/vm.h> header so that the OS specific struct can be pulled into struct nvgpu_mapped_buf. Next renaming the nvgpu_vm_map() to nvgpu_vm_map_linux() is in preparation for adding a new nvgpu_vm_map() that handles the map caching with nvgpu_mapped_buf. The mapping code is fairly straight forward: nvgpu_vm_map does OS generic stuff; each OS then calls this function from an nvgpu_vm_map_<OS>() or the like that does any OS specific adjustments/management. Freeing buffers is much more tricky however. The maps are all reference counted since userspace does not track buffers and expects us to handle this instead. Ugh! Since there's ref-counts the free code will require a callback into the OS specific code since the OS specific code cannot free a buffer directly. THis make's the path for freeing a buffer quite convoluted.

* gpu: nvgpu: Cleanup generic MM code in gk20a/mm_gk20a.cAlex Waterman2017-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move much of the remaining generic MM code to a new common location: common/mm/mm.c. Also add a corresponding <nvgpu/mm.h> header. This mostly consists of init and cleanup code to handle the common MM data structures like the VIDMEM code, address spaces for various engines, etc. A few more indepth changes were made as well. 1. alloc_inst_block() has been added to the MM HAL. This used to be defined directly in the gk20a code but it used a register. As a result, if this register hypothetically changes in the future, it would need to become a HAL anyway. This path preempts that and for now just defines all HALs to use the gk20a version. 2. Rename as much as possible: global functions are, for the most part, prepended with nvgpu (there are a few exceptions which I have yet to decide what to do with). Functions that are static are renamed to be as consistent with their functionality as possible since in some cases function effect and function name have diverged.

* gpu: nvgpu: Convert VIDMEM work_struct to threadAlex Waterman2017-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert the work_struct used by the vidmem background clearing to a thread to make it more cross platform. The thread waits on a condition variable to determine when work needs to be done. The signal comes from the DMA API when it enqueues a new nvgpu_mem that needs clearing. Add logic for handling suspend: the CE cannot be accessed while the GPU is suspended. As such the background thread must be paused while the GPU is suspended and the CE is not available. Several other changes were also made: o Move the code that enqueues a nvgpu_mem from the DMA API code to a function in the VIDMEM code. o Move nvgpu_vidmem_get_pending_alloc() to the Linux specific code as this function is only used there. It's a trivial function that QNX can easily implement as well. o Remove the was_empty logic from the enqueue. Now just always signal the condition variable when anew nvgpu_mem comes in. o Move CE suspend to after MM suspend.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move most of the dma_buf usage present in the mm_gk20a.c code out to Linux specific code and some commom/mm code. There's two primary groups of code: 1. dma_buf priv field code (for holding comptag data) 2. Comptag usage that relies on dma_buf pointers For (1) the dma_buf code was simply moved to common/linux/dmabuf.c since most of this code is clearly Linux specific. The comptag code was a bit more complicated since there is two parts to the comptag code. Firstly there's the code that manages the comptag memory. This is essentially a simple allocator. This was moved to common/mm/comptags.c since it can be shared across all chips. The second set of code is moved to common/linux/comptags.c since it is the interface between dma_bufs and the comptag memory. Two other fixes were done as well: - Add struct gk20a to the comptag allocator init so that the proper nvgpu_vzalloc() function could be used. - Add necessary includes to common/linux/vm_priv.h.

* gpu: nvgpu: add API to create nvgpu_mem from physseshendra Gadagottu2017-10-13
| | | | | | | | | | | | | | | | | | | | Added new memory API _nvgpu_mem_create_from_phys for creating nvgpu_mem from physical memory aperture. With this new API, avoided usage of linux specific "struct page" in general code and moved this code to common linux code. This API internally uses __nvgpu_mem_create_from_pages for creating nvgpu_mem from physical pages.

| | | | | | | | | | | | | | | | | | | | | Some GPUs require all channels to be on TSG and also have larger than 4GB vidmem sizes which were not supported on the previous CE2 code. This change creates a new property to track if the copy engine needs to encapsulate its kernel context on tsg and also modifies the copy engine code to support much larger copies without dramatically increasing the PB size.

| | | | | | | | | | | | | | | | | | | | | | When freeing kmalloc and vmalloc buffers memset them to zero before freeing them with the kernel APIs. This is only done if CONFIG_NVGPU_TRACK_MEM_USAGE is set since this adds obvious overhead to the driver. However, it is an incredibly useful debug tool, so it's nice to have. This could be done by enabling Linux kernel configs as well, but not all OSes may have such a feature so building it into nvgpu may prove quite useful.

With the proper nvgpu_sgt abstraction in place the high level mapping code can treat these two types of maps identically. The benefits of this are immediate: a change to the mapping code will have much more testing coverage - the same code runs on both vidmem and sysmem. This also makes it easier to make changes to mapping code since the changes will be testable no matter what type of mem is being mapped.
