* gpu: nvgpu: Make context mapping non-cacheablePeter Boonstoppel2017-02-06
| | | | | | | | | | | | | | | | | | Changes to the context header after the context has been loaded may not be visible to the GPU when mapped as cacheable memory. Examples include updating the preemption modes or boosted_ctx bits at runtime. This patch changes the mapping to non-cacheable.

* gpu: nvgpu: Unify the small and large page address spacesAlex Waterman2017-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The basic structure of this patch is to make the small page allocator and the large page allocator into pointers (where they used to be just structs). Then assign each of those pointers to the same actual allocator since the buddy allocator has supported mixed page sizes since its inception. For the rest of the driver some changes had to be made in order to actually support mixed pages in a single address space. 1. Unifying the allocation page size determination Since the allocation and map operations happen at distinct times both mapping and allocation of GVA space must agree on page size. This is because the allocation has to separate allocations into separate PDEs to avoid the necessity of supporting mixed PDEs. To this end a function __get_pte_size() was introduced which is used both by the balloc code and the core GPU MM code. It determines page size based only on the length of the mapping/ allocation. 2. Fixed address allocation + page size Similar to regular mappings/GVA allocations fixed address mapping page size determination had to be modified. In the past the address of the mapping determined page size since the address space split was by address (low addresses were small pages, high addresses large pages). Since that is no longer the case the page size field in the reserve memory ioctl is now honored by the mapping code. When, for instance, CUDA makes a memory reservation it specifies small or large pages. When CUDA requests mappings to be made within that address range the page size is then looked up in the reserved memory struct. Fixed address reservations were also modified to now always allocate at a PDE granularity (64M or 128M depending on large page size. This prevents non-fixed allocations from ending up in the same PDE and causing kernel panics or GMMU faults. 3. The rest... The rest of the changes are just by products of the above. Lots of places required minor updates to use a pointer to the GVA allocator struct instead of the struct itself. Lastly, this change is not truly complete. More work remains to be done in order to fully remove the notion that there was such a thing as separate address spaces for different page sizes. Basically after this patch what remains is cleanup and proper documentation.

* gpu: nvgpu: use map_offset for PTE size computationAlex Waterman2017-01-31
| | | | | | | | | | | | | | | | | | | | | | Make sure that map_offset is set to the fixed map address or 0) before determining PTE size. Then use map_offset instead of offset_align for computing the PTE size since offset_align could be either an alignment ora fixed mapping offset. Also is the minimum of the buffer size and the buffer alignment for computing page size. This is necessary is the GMMU is doing page gathering (i.e the buffer does not appear as a continguous IOMMU range to the GPU). Is such cases a large page sized buffer may be made up of a bunch of discontiguous 4k pages.

The exit label checks if boardobj is NULL and calls destructor if it is. As there is no path to get to exit label with boardobj NULL, skip the check.

* gpu: nvgpu: Make driver rebind workAlex Waterman2017-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the GPU bind and rebind operations work when the driver is idle. This required two changes. 1. Reset the GPU before doing SW init for PCI GPUs. This clears the SW state which may be stale in the case of a rebind attempt. 2. Cleanup the interrupt enable/disables. Firstly there was one place where nvgpu would accidentally disable the stalling interrupt twice when the stalling interrupt and non-stalling interrupt are the same. Secondly make sure when exiting nvgpu that the interrupt enable/disables are balanced. Leaving the interrupt in the -1 disable state means that next time the driver runs interrupts never quite get enabled.
