| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have below race condition during __gk20a_do_idle() and force_reset case : - before execution of __gk20a_do_idle(), a process drops the last usage count of GPU, which triggers GPU railgate process - but before GPU is really railgated (there is 500 mS delay), some process calls __gk20a_do_idle() - in __gk20a_do_idle(), we first take railgate_lock - then we check if GPU is already railgated or not - since it is not railgated yet (due to 500 mS delay), this returns false - then we call pm_runtime_get_noresume() which just increases the usage counter - in this particular case, this call just increases usage count to 1 from 0, but whereas GPU is already on its way to railgate - while we check if GPU usage count drops to one, GPU gets railgated - now if we have force_reset=true case, we will end up calling pm_runtime_get_sync() which will take railgate_lock lock _again_ and try to unrailgate GPU - this causes a deadlock on railgate_lock To fix this, use below sequence : - take railgate_lock - check if GPU is already railgated - release railgate_lock - call pm_runtime_get_sync() which will keep GPU active even if railgating is already triggered - take railgate_lock again to prevent unrailgate in futher process Also, add more descriptive comments to explain the flow Bug 1624537 Change-Id: I0febc65d7bfac03ee738be200cf321322ffbe5a6 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/719625 (cherry picked from commit 480284eda16e2b50ee6368bad3d15574e098b231) Reviewed-on: http://git-master/r/719620 Reviewed-by: Sachin Nikam <snikam@nvidia.com>

* 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.

* gpu: nvgpu: WAR for simulator bugAlex Waterman2015-05-11
| | | | | | | | | | | | | | | | | | | On linsim, when the push buffers are allowed to be allocated with small pages above 4GB the simulator crashes. This patch ensures that for linsim all small page allocations are forced to be below 4GB in the GPU VA space. By doing so the simulator no longer crashes. This bug has come up because the GPU buddy allocator work generates allocations at the top of the address space first. Thus push buffers were located at between 12GB and 16GB in the GPU VA space.
