* gpu: nvgpu: add g cross reference in boardobjgrpThomas Fleury2017-11-06
| | | | | | | | | | | | | | Added a pointer to GPU context in boardobjgrp, and updated constructors. It will be useful to free allocated DMA resources.

* gpu: nvgpu: support tuning per-ch deterministic optsKonsta Holtta2017-11-06
| | | | | | | | | | | | | | | | Add a new ioctl NVGPU_GPU_IOCTL_SET_DETERMINISTIC_OPTS to adjust deterministic options on a per-channel basis. Currently, the only supported option is to relax the no-railgating requirement on open deterministic channels. This also disallows submits on such channels, until the railgate option is reset.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | gr_gk20a_ctx_patch_write_begin() updates the patch buffer data_count when the associated graphics context memory buffer has been CPU-mapped; it was doing so by looking for a non-null cpu_va. However, if the graphics context has been allocated from vidmem, cpu_va is always 0, so we can't tell if nvgpu_mem_begin() was called for the context buffer or not. Instead: - add a cpu_accessible flag to the nvgpu_mem struct and set it in nvgpu_mem_begin() - return the value of that flag in nvgpu_mem_cpu_accessible() - gr_gk20a_ctx_patch_write_begin() now calls this new function instead of checking cpu_va.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the always true field 'user_mapped' from the mapped_buf struct. All mapped_bufs are mapped by a user request since they always originate from a dma_buf (for Linux, that is). As such there is a fair amount of logic that could be deleted. Linux specific: the own_mem_ref field was also be deleted. The logic of only storing a dma_buf ref when the buffer is mapped for the first time by a user is easy: when the mapped buffer is found in the map cache release the outstanding dma_buf ref taken earlier on in the map path. If the map cache does not have the buffer simply let the higher level map code keep the dma_buf ref. The dma_buf ref is released when the nvgpu_vm_unmap_system() call-back is called by the unmap path.

* gpu: nvgpu: VM unmap refactoringAlex Waterman2017-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Re-organize the unmap code to be better split between OS specific requirements and common core requirements. The new code flow works as follows: nvgpu_vm_unmap() Is the primary entrance to the unmap path. It takes a VM and a GPU virtual address to unmap. There's also an optional batch mapping struct. This function is responsible for making sure there is a real buffer and that if it's being called on a fixed mapping then the mapping will definitely be freed (since buffers are ref-counted). Then this function decrements the ref-count and returns. If the ref-count hits zero then __nvgpu_vm_unmap_ref() is called which just calls __nvgpu_vm_unmap() with the relevant batch struct if present. This is where the real work is done. __nvgpu_vm_unmap() clears the GMMU mapping, removes the mapped buffer from the various lists and trees it may be in and then calls the nvgpu_vm_unmap_system() function. This function handles any OS specific stuff and must be defined by all VM OS implementations. There's a a short cut used by some other core VM code to free mappings without going through nvgpu_vm_map(). Mostly they just directly decrement the mapping ref-count which can then call __nvgpu_vm_unmap_ref() if the ref-count hits zero.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate ctxsw_trace_gk20a.c to common/linux/ctxsw_trace.c. This has been done becasue the ctxsw tracing code is currently too tightly tied to the Linux OS due to usage of a couple system calls: - poll() - mmap() And general Linux driver framework code. As a result pulling the logic out of the FECS tracing code is simply too large a scope for time time being. Instead the code was just copied as much as possible. The HAL ops for the FECS code was hidden behind the FECS tracing config so that the vm_area_struct is not used when QNX does not define said config. All other non-HAL functions called by the FECS ctxsw tracing code ha now also been hidden by this config. This is not pretty but for the time being it seems like the way to go.
