2017-09-26drm/amdgpu: Track pending retry faults in IH and VM (v2)Felix Kuehling5-1/+179
IH tracks pending retry faults in a hash table for fast lookup in interrupt context. Each VM has a short FIFO of pending VM faults for processing in a bottom half. The IH prescreening stage adds retry faults and filters out repeated retry interrupts to minimize the impact of interrupt storms. It's the VM's responsibility remove pending faults once they are handled. For now this is only done when the VM is destroyed. v2: - Made the hash table smaller and the FIFO longer. I never want the FIFO to fill up, because that would make prescreen take longer. 128 pending page faults should be enough to keep migrations busy.

2017-09-26drm/amdgpu: Add PASID managementFelix Kuehling5-4/+91
Allows assigning a PASID to a VM for identifying VMs involved in page faults. The global PASID manager is also exported in the KFD interface so that AMDGPU and KFD can share the PASID space. PASIDs of different sizes can be requested. On APUs, the PASID size is deterined by the capabilities of the IOMMU. So KFD must be able to allocate PASIDs in a smaller range.

2017-09-14drm/amdgpu: revert tile table update for olandJean Delvare1-1/+188
Several users have complained that the tile table update broke Oland support. Despite several attempts to fix it, the root cause is still unknown at this point and no solution is available. As it is not acceptable to leave a known regression breaking a major functionality in the kernel for several releases, let's just reverse this optimization for now. It can be implemented again later if and only if the breakage is understood and fixed. As there were no complaints for Hainan so far, only the Oland part of the offending commit is reverted. Optimization is preserved on Hainan, so this commit isn't an actual revert of the original.

Allow interval trees to quickly check for overlaps to avoid unnecesary tree lookups in interval_tree_iter_first(). As of this patch, all interval tree flavors will require using a 'rb_root_cached' such that we can have the leftmost node easily available. While most users will make use of this feature, those with special functions (in addition to the generic insert, delete, search calls) will avoid using the cached option as they can do funky things with insertions -- for example, vma_interval_tree_insert_after().

The header comment in include/trace/define_trace.h specifies that the TRACE_INCLUDE_PATH needs to be relative to the define_trace.h header rather than the trace file including it. Most instances get that wrong and work around it by adding the $(src) directory to the include path.
