* 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: fix MISRA Rule 11.6 issue with _THIS_IP_Scott Long2018-07-30
| | | | | | | | | | | | | | | | | | | | | | | | | The use of the _THIS_IP_ macro in nvgpu introduces two separate MISRA Rule 11.6 violations. The first is when when the label address (which gcc generates as a void *) is cast to an unsigned long and the second is when that unsigned long is cast back to a void * in the timer and kmem code that track the value. Skipping the intermediate use of unsigned long eliminates these violations. To do this, references to _THIS_IP_ are replaced with a new (compliant) _NVGPU_GET_IP_ macro.

With fixes related to replacing tsg preempt with runlist preempt during teardown, preempt timeout set to 100 ms (earlier this was set to 1000ms for t194 and 3000ms for legacy chips) and not issuing preempt timeout recovery if preempt fails, helped resolve the issue.
