Set the VM size based on system memory size between the ASIC-specific limits given by min_vm_size and max_bits. GFXv9 GPUs will keep their default VM size of 256TB (48 bit). Only older GPUs will adjust VM size depending on system memory size. This makes more VM space available for ROCm applications on GFXv8 GPUs that want to map all available VRAM and system memory in their SVM address space. v2: * Clarify comment * Round up memory size before >> 30 * Round up automatic vm_size to power of two Signed-off-by: NFelix Kuehling <Felix.Kuehling@amd.com> Acked-by: NJunwei Zhang <Jerry.Zhang@amd.com> Reviewed-by: NHuang Rui <ray.huang@amd.com> Reviewed-by: NChristian König <christian.koenig@amd.com> Signed-off-by: NAlex Deucher <alexander.deucher@amd.com>

This moves and renames the AMDGPU scheduler to a common location in DRM in order to facilitate re-use by other drivers. This is mostly a straight forward rename with no code changes. One notable exception is the function to_drm_sched_fence(), which is no longer a inline header function to avoid the need to export the drm_sched_fence_ops_scheduled and drm_sched_fence_ops_finished structures.

When many wavefronts cause VM faults at the same time, it can overwhelm the interrupt handler and cause IH ring overflows before the driver can notify or kill the faulting application. As a workaround I'm introducing limited per-VM fault credit. After that number of VM faults have occurred, further VM faults are filtered out at the prescreen stage of processing. This depends on the PASID in the interrupt packet, so it currently only works for KFD contexts.

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.

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.

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().
