* gpu: nvgpu: Move Linux files away from commonTerje Bergstrom2018-06-15
| | | | | | | | | | | | | | | Move all Linux source code files to drivers/gpu/nvgpu/os/linux from drivers/gpu/nvgpu/common/linux. This changes the meaning of common to be OS independent.

* gpu: nvgpu: update ecc sysfs node handlingNitin Kumbhar2018-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | Make ecc sysfs hash table per GPU by adding it as part of nvgpu_os_linux. Using a single hash table might give incorrect results as GPUs have same filenames and a filename is used as a key for a lookup. Add device_attribute as part of struct gk20a_ecc_stat. Using a single array of pointers of device attribute for an ecc_stat results in memory leak and incorrect stats if multiple GPUs are present on the system. This array of pointers will always hold info for GPU which created sysfs nodes last. Fix this by making device attribute array per ecc stat per GPU. Fix ecc stat removal to consider zero sub-units for a given number of hwunits. The multiplication with zero results in not removing any sysfs node at all.

* gpu: nvgpu: Cleanup usage of bypass_smmuAlex Waterman2018-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GPU has multiple different operating modes in respect to IOMMU'ability. As such there needs to be a clean way to tell the driver whether it is IOMMU'able or not. This state also does not always reflect what is possible: all becasue the GPU can generate IOMMU'ed memory requests doesn't mean it wants to. The nvgpu_iommuable() API has now existed for a little while which is a useful way to convey whether nvgpu should consider the GPU as IOMMU'able. However, there is also the g->mm.bypass_smmu flag which used to be able to override what the GPU decided it should do. Typically it was assigned the same value as nvgpu_iommuable() but that was not necessarily a requirment. This patch removes all the usages of g->mm.bypass_smmu and instead uses the nvgpu_iommuable() function. All places where the check against g->mm.bypass_smmu have been replaced with nvgpu_iommuable(). The code should now be much cleaner. Subsequently other checks can also be placed in the nvgpu_iommuable() function. For example, when NVLINK comes online and the GPU should no longer consider DMA addresses and instead use scatter-gather lists directly the ngpu_iommuable() function will be able to check the state of NVLINK and then act accordingly.

* gpu: nvgpu: use submit callback only in linux codeKonsta Holtta2017-11-22
| | | | | | | | | | | | | | | | | Move the implementation for channel job update callbacks that is based on Linux specific work_struct usage to Linux-specific code. This requires a bit of extra work for allocating OS-specific priv data for channels which is also done in this patch. The priv data will be used more when more OS-specific features are moved.

* gpu: nvgpu: Remove Linux headers from mm_gk20a.hAlex Waterman2017-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | Delte the Linux headers and make some modifications to get rid of the minor compilation issues that resulted. - Add <linux/iommu.h> to os_linux.h - Delete #if 0 code that "flushed" a buffer in gr_gk20a.c - Delete FLUSH_CPU_DCACHE() macro - Move the cache flush definitions to <nvgpu/linux/vm.h> and include this header in sim_gk20a.c. This file will not be used by QNX so this should be fine. - Add <linux/pci_ids.h> to gp106/bios_gp106.c and gp106/mclk_gp106.c. - Move function to common/linux/dmabuf.h since it is a dmabuf related function and uses a struct device pointer as an argument.
