* gpu: nvgpu: Remove falcon header usage in nvlinkTejal Kudav2018-08-22

* gpu: nvgpu: Force the PMU VM to use 128K large pages (gm20b)Alex Waterman2018-08-21
| | | | | | | | | | | | | | | Add a WAR for gm20b that allows us to force the PMU VM to use 128K large pages. For some reason setting the small page size to 64K breaks the PMU boot. Unclear why. Bug needs to be filed and fixed. Once fixed this patch can and should be reverted.

* gpu: nvgpu: Set default large page size to 64K for gm20bAlex Waterman2018-08-21
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* gpu: nvgpu: Add U64() and U32() macrosAlex Waterman2018-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These macros exist to make integer literals used in certain arithmetic operations explicitly large enough to hold the results of that operation. The following is an example of this. In MISRA the destination for a bitwise shift must be able to hold the number of bits shifted. Otherwise the results are undefined. For example: 256U << 20U This is valid C code but the results of this _may_ be undefined if the size of an unsigned by default is less than 24 bits (i.e 16 bits). The MISRA misra checker sees the 256U and determines that the 256U fits in a 16 bit data type (i.e a u16). Since a u16 has 16 bits, which is less than 20, this is an issue. Of course most compilers these days use 32 bits for the default unsigned type this is not a requirement. Moreover this name problem could exist like so: 0xfffffU << 40U The 0xfffffU is a 32 bit unsigned type; but we are shifting 40 bits which overflows the 32 bit data type. So in this case we need an explicit cast to 64 bits in order to prevent undefined behavior.
