2017-12-09drm/amdkfd: Add perf counters to topologyAmber Lin2-2/+127
For hardware blocks whose performance counters are accessed via MMIO registers, KFD provides the support for those privileged blocks. IOMMU is one of those privileged blocks. Most performance counter properties required by Thunk are available at /sys/bus/event_source/devices/amd_iommu. This patch adds properties to topology in KFD sysfs for information not available in /sys/bus/event_source/devices/amd_iommu. They are shown at /sys/devices/virtual/kfd/kfd/topology/nodes/0/perf/iommu/ formatted as /sys/devices/virtual/kfd/kfd/topology/nodes/0/perf/<block>/<property>, i.e. /sys/devices/virtual/kfd/kfd/topology/nodes/0/perf/iommu/max_concurrent. For dGPUs, who don't have IOMMU, nothing appears under /sys/devices/virtual/kfd/kfd/topology/nodes/0/perf.

2017-12-09drm/amdkfd: Add topology support for CPUsFelix Kuehling5-35/+489
Currently, the KFD topology information is generated by parsing the CRAT (ACPI) table. However, at present CRAT table is available only for AMD APUs. To support CPUs on systems without a CRAT table, the KFD driver will create a Virtual CRAT (VCRAT) table and then the existing code will parse that table to generate topology.

Use a reference counter instead of a lock to prevent process destruction while functions running out of process context are using the kfd_process structure. In many cases these functions don't need the structure to be locked. In the few cases that really do need the process lock, take it explicitly. This helps simplify lock dependencies between the process lock and other locks, particularly amdgpu and mm_struct locks. This will be important when amdgpu calls back to amdkfd for memory evictions.
