* gpu: nvgpu: Reorganize ltc HAL initializationSunny He2017-06-27
| | | | | | | | | | | | | | | | | Reorganize HAL initialization to remove inheritance and construct the gpu_ops struct at compile time. This patch only covers the ltc sub-module of the gpu_ops struct. Perform HAL function assignments in hal_gxxxx.c through the population of a chip-specific copy of gpu_ops.

* gpu: nvgpu: remove ltc_common.cSunny He2017-06-27
| | | | | | | | | | | | | | | | | | | | | | | | Remove ltc_common.c and integrate the included functions into device specific ltc_gXXXX.c files. Merge non-device reg definition dependent ltc functions into ltc_gk20a.c/h. Prior to this patch, ltc_common.c was being directly included into the device specific ltc source files as a workaround to allow different devices to share the same code but still include in different hw reg definitions. Given that this approach was not adopted for other systems, this code has been separated out for readability and consistency.

* gpu: nvgpu: Begin removing variables in struct gk20aAlex Waterman2017-05-30
| | | | | | | | | | | | | | | | | | | | | | Begin removing all of the myriad flag variables in struct gk20a and replace that with one API that checks for flags being enabled or disabled. The API is as follows: bool nvgpu_is_enabled(struct gk20a *g, int flag); bool __nvgpu_set_enabled(struct gk20a *g, int flag, bool state); These APIs allow many of the gk20a flags to be replaced by defines. This makes flag usage consistent and saves a small amount of memory in struct gk20a. Also it makes struct gk20a easier to read since there's less clutter scattered through out.

* gpu: nvgpu: remove duplicate \n from log messagesStephen Warren2017-05-26
| | | | | | | | | | | | | | | nvgpu_log/info/warn/err() internally add a \n to the end of the message. Hence, callers should not include a \n at the end of the message. Doing so results in duplicate \n being printed, which ends up creating empty log messages. Remove the duplicate \n from all err/warn messages.

This commit reverts partially the combination of the above commit and also one after it, 86fc7ec9a05999bea8de320840b962db3ee11410, that fixed a bug which is not present when using a bitmap. With a bitmap allocator, pruning the extra allocation necessary for user-mapped mode is possible, so that is also restored. The original generic bitmap allocator is not restored; instead, a comptag-only allocator is introduced.

* gpu: nvgpu: New allocator for VA spaceAlex Waterman2015-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a new buddy allocation scheme for the GPU's VA space. The bitmap allocator was using too much memory and is not a scaleable solution as the GPU's address space keeps getting bigger. The buddy allocation scheme is much more memory efficient when the majority of the address space is not allocated. The buddy allocator is not constrained by the notion of a split address space. The bitmap allocator could only manage either small pages or large pages but not both at the same time. Thus the bottom of the address space was for small pages, the top for large pages. Although, that split is not removed quite yet, the new allocator enables that to happen. The buddy allocator is also very scalable. It manages the relatively small comptag space to the enormous GPU VA space and everything in between. This is important since the GPU has lots of different sized spaces that need managing. Currently there are certain limitations. For one the allocator does not handle the fixed allocations from CUDA very well. It can do so but with certain caveats. The PTE page size is always set to small. This means the BA may place other small page allocations in the buddies around the fixed allocation. It does this to avoid having large and small page allocations in the same PDE.
