drm/amdkfd: Add spatial partitioning support in KFD
This patch introduces multi-partition support in KFD.
This patch includes:
- Support for maximum 8 spatial partitions in KFD.
- Initialize one HIQ per partition.
- Management of VMID range depending on partition mode.
- Management of doorbell aperture space between all
partitions.
- Each partition does its own queue management, interrupt
handling, SMI event reporting.
- IOMMU, if enabled with multiple partitions, will only work
on first partition.
- SPM is only supported on the first partition.
- Currently, there is no support for resetting individual
partitions. All partitions will reset together.
