* gpu: nvgpu: fix indexing in locate pte functionDavid Nieto2017-12-05
| | | | | | | | | | | | | | | | | | | The current code does not properly calculate the indexes within the PDE to access the proper entry, and it has a bug in assignement of the big page entries. This change fixes the issue by: (1) Passing a pointer to the level structure and dereferencing the index offset to the next level. (2) Changing the format of the address. (3) Ensuring big pages are only selected if their address is set.

* gpu: nvgpu: remove dependency on linux header for regops_gk20a*Debarshi Dutta2017-11-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the dependency on the header file "uapi/linux/nvgpu.h" for regops_gk20a.c. The original structure and definitions in the uapi/linux/nvgpu.h is maintained for userspace libnvrm_gpu.h. The following changes are made in this patch. 1) Defined common versions of the NVGPU_DBG_GPU_REG_OP* definitions inside regops_gk20a.h. 2) Defined common version of struct nvgpu_dbg_gpu_reg_op inside regops_gk20a.h naming it struct nvgpu_dbg_reg_op. 3) Constructed APIs to convert the NVGPU_DBG_GPU_REG_OP* definitions from linux versions to common and vice versa. 4) Constructed APIs to convert from struct nvgpu_dbg_gpu_reg_op to struct nvgpu_dbg_reg_op and vice versa. 5) The ioctl handler nvgpu_ioctl_channel_reg_ops first copies from userspace into a local storage based on struct nvgpu_dbg_gpu_reg_op which is copied into the struct nvgpu_dbg_reg_op using the APIs above and after executing the regops handler passes the data back into userspace by copying back data from struct nvgpu_dbg_reg_op to struct nvgpu_dbg_gpu_reg_opi.

* gpu: nvgpu: Use only contig CBCsAlex Waterman2017-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the LTC code to only use a contiguous CompBit Cache (CBC). The original code had two allocation schemes: "physical" and "virtual" - what they meant was virtually contiguous or physically contiguous. The CBC must appear contiguous to the GPU be it either from the IOMMU or from physical pages allocated contiguously. This change makes the CBC get allocated with the FORCE_CONTIGUOUS flag if the GPU is not IOMMU'able. If we can get contiguous mem with the IOMMU then no need to force the underlying pages to be contiguous. However, not all GPUs may be IOMMU'able so we do need to handle that case. Also delete the gk20a/ltc_gk20a.[ch] code. All that remained in these files was the CBC alloc functions which were completely chip agnostic. As a result these functions were consolidated and moved to common/ltc.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | Add max_css_buffer_size to gpu characteristics. In the virtual case, the size of the cycle stats snapshot buffer is constrained by the size of the mempool shared between the guest OS and the RM server, so tools need to find out what is the maximum size allowed. In the native case, we return 0xffffffff to indicate that the buffer size is unbounded (subject to memory availability), in the virtual case we return the size of the mempool. Also collapse native init_cyclestats functions to a single version, as each chip had identical versions of the code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
