* 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: add g->sw_ready flagKonsta Holtta2018-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | Fix a race condition where we'd still be booting up the gpu and/or initializing the driver but elsewhere assume that all is done already. Some userspace APIs to make sure that we're ready by testing g->gr.sw_ready, but this flag is set in the middle of bootup; there are other things after gr initialization. Add a new flag that is enabled after bootup is fully complete at the end of finalize_poweron, and change the checks in user API paths to test the new flag only. These checks are only in the ioctl paths for ctrl, dbg and tsg, and in the ctrl device's opening path. The gr.sw_ready flag is still left there to signify whether just gr has had its bookkeeping initialized.
