* gpu: nvgpu: Read sm error ioctl support for tsgVinod G2018-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | Add READ_SM_ERROR IOCTL support to TSG level. Moved the struct to save the sm_error details from gr to tsg as the sm_error support is context based, not global. Also corrected MISRA 21.1 error in header file. nvgpu_dbg_gpu_ioctl_write_single_sm_error_state and nvgpu_dbg_gpu_ioctl_read_single_sm_error_state functions are modified to use the tsg struct nvgpu_tsg_sm_error_state.

| | | | | | | | | | | | | | | | | | | | | | | | Since all userspace apps are using 64K pages these days it makes sense to set the default large page size to 64K. This in turn causes the PDE coverage field to be set to 64M in the GPU characteristics field. While it would therefor be possible to create a VM with a PDE coverage that's larger than 64M (128M if you set the large page size to 128K) this will make the defaults work properly. This in turn fixes a CUDA issue where CUDA tries to determine the PDE coverage (and correspondingly a minimum alignemnt) from the characteristics IOCTL.

* gpu: nvgpu: Use correct aperture for perf inst_blockAlex Waterman2018-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | The perf inst block was being treated as vidmem (LFB - local framebuffer) always, regardless of the type of nvgpu_mem used for the instance block. On dGPUs this was fine becasue we always allocate instance blocks from vidmem. Inst blocks are allocated with nvgpu_dma_alloc() which chooses vidmem if vidmem is present, otherwise falls back to sysmem. When the above fall back logic was deleted this caused inst blocks to always be allocated in sysmem, even for dGPUs. This isn't a problem in an of itself but the logic for the perf instance block bind operation assumed a VIDMEM inst_block. Thus this patch uses the nvgpu_aperture_mask() function to correctly program the required aperture target for the perf's inst block bind operation.

* gpu: nvgpu: Use NVLINK config instead of has_physical_modeAlex Waterman2018-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This flag - has_physical_mode - doesn't seem to do much other than force the PTE/PDE and inst block addresses to be physical instead of potentially IOMMUed. There is a reason to do this on volta (nvlink not being IOMMU'able being the primary reason) but this flag is too general it seems. The flag was being enabled on all native platforms. The problem is that some page tables (the maxwell small page directories) could be larger than 4KB which meant that the allocation used for them could be potentially discontiguous. Discontiguous page directories obviously is incorrect. This patch deletes the has_physical_mode flag and instead replaces the places where it's checked with a check for nvlink being enabled. Since we _do_ want to program phyiscal PDEs and PTEs for NVLINK devices (regardless of IOMMU status they always access memory by physical address) we need a check for NVLINK state.
