* gpu: nvgpu: gv11b: add scg support info in gpu characteristicsseshendra Gadagottu2018-02-02

Bug 2053932 Change-Id: I788e22242083dff775dd4cc5b9aa73c938028536 Signed-off-by: seshendra Gadagottu <sgadagottu@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1649805 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* 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: Remove init_state initialization codeTejal Kudav2018-02-02
| | | | | | | | | | | | | | | | | | nvlink core library no longer exposes the set_init_state() interface as it wishes to block init_state changes from endpoint drivers. Now, the core driver is responsible for initializing init_state variables using set_init_state() interface. Hence, we remove this redundant code.

* gpu: nvgpu: Set DMA mask to 34 bitsAlex Waterman2018-02-01
| | | | | | | | | | | | | | | | | | Set the DMA mask to 34 bits so that large DMA allocs can be done. Currently the DMA mask is left unset which limits the size of the maximum DMA allocation to 32 bits. The 34 bit mask was chosen because it works for all chips (even gm20b supports 34 bit physical addresses). However, newer chips could use larger masks in the future if they desire.

By moving .tsg_unbind_channl one layer lower, gk20a_tsg_unbind_channel() will be common functions for all chip, and it'll call tsg release after call .tsg_unbind_channel.

* gpu: nvgpu: Cleanup '\n' usage in allocator debuggingAlex Waterman2018-01-25
| | | | | | | | | | | | | | | | | | These '\n' were leftover from the previous debugging macro usage which did no add the '\n' automagically. However, once swapped over to the nvgpu logging system the '\n' is added and no longer needs to be present in the code. This did require one extra modification though to keep things consistent. The __alloc_pstat() macro, used for sending output either to a seq_file or the terminal, needed to add the '\n' for seq_printf() calls and the '\n' had to be deleted in the C files.

Anything not a vmalloc address is then assumed to be a kmalloc() address.
