* 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.

This patch introduces a software shadow for gpu load. The shadow is updated before starting scaling and all scaling code paths use the sw shadow.

* gpu: nvgpu: fix possible PMU isr raceDeepak Nibade2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Possible race description : - while PMU is booting, it sends messages to kernel which we process in gk20a_pmu_isr() - but when messages are processed it is possible that we are on the way to rail gate the GPU and we have already called pmu_destroy() - this could lead to hangs if while processing messages, GR is already off To fix this, introduce another mutex isr_enable_lock and a flag to turn on/off ISRs - when we enable PMU, get the lock and set the flag - in pmu_destroy(), get the lock and remove the flag - in pmu_isr(), take the lock, check if flag is set or not. If flag is not set return, otherwise proceed with the messages Bug 200014542 Bug 200014887 Change-Id: I0204d8a00e4563859eebc807d4ac7d26161316ea Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/428371 (cherry picked from commit 9a37528314f2a2504e4530719f817a93db9a5bf0) Reviewed-on: http://git-master/r/428352 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Sachin Nikam <snikam@nvidia.com>
