* gpu: nvgpu: Fixups for tmake buildAlex Waterman2018-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Mostly just including necessary includes to make sure that global function declarations actually match their implementations. Also work around pointer munging warning: /build/ddpx/linux/kernel/nvgpu/drivers/gpu/nvgpu/common/pmu/pmu.c: In function 'nvgpu_pmu_process_init_msg': /build/ddpx/linux/kernel/nvgpu/drivers/gpu/nvgpu/common/pmu/pmu.c:348:4: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing] (*(u32 *)gid_data.signature == PMU_SHA1_GID_SIGNATURE); Work around this warning by simply moving the type punning. This code is certainly dangerous - it assumes the endianness of the header data is the same as the machine this code is running on. Apparently it works, though, so this ignores the warning.

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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch buffer can hold 128 u32 entries. Each patch write takes total of 2 u32 entries, 1 u32 for addr and 1 u32 for data. Ideally 64 entries could be written before buffer overflows. Driver patch some things when creating the channel, and later when context switch type is changed after channel is loaded. Reset patch_ctx.data_count before beginning patch write otherwise system might not be in a state to accept all patch writes even if patch buffer has valid entries. If the patch buffer has non-zero entries, then the patch buffer would be read and all pri writes would be sent out. Once done, ucode updates the main header patch buffer count to 0.

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