drm/amdkfd: Centralize IOMMUv2 code and make it conditional

2017-12-09T00:22:12Z

dGPUs work without IOMMUv2. Make IOMMUv2 initialization dependent on ASIC information. Also allow building KFD without IOMMUv2 support. This is still useful for dGPUs and prepares for enabling KFD on architectures that don't support AMD IOMMUv2. v2: * Centralize IOMMUv2 code to avoid #ifdefs in too many places v3: * Imply AMD_IOMMU_V2 in Kconfig Signed-off-by: Felix Kuehling Acked-by: Christian Konig Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Use ARRAY_SIZE macro in kfd_build_sysfs_node_entry

2018-01-19T00:39:55Z

Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element. This issue was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R. Silva Reviewed-by: Felix Kuehling Signed-off-by: Oded Gabbay

drm/amdkfd: Ignore ACPI CRAT for non-APU systems

2017-12-09T04:09:04Z

Some AMD motherboards without an APU have a broken CRAT table which causes KFD initialization failures or incorrect information about NUMA nodes, CPU cores or system memory. Ignore CRAT tables without GPUs and rely on KFD's code to create a CRAT table for the CPU.

drm/amdkfd: Add AQL Queue Memory flag on topology

drm/amdkfd: Add perf counters to topology

2017-12-09T04:09:00Z

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//, 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.

drm/amdkfd: Add topology support for dGPUs

2017-12-09T04:08:59Z

Generate and parse VCRAT tables for dGPUs in kfd_topology_add_device. Some information that isn't available in the CRAT table is patched into the topology after parsing. HSA_CAP_DOORBELL_TYPE_1_0 is dependent on the ASIC feature CP_HQD_PQ_CONTROL.SLOT_BASED_WPTR, which was not introduced in VI until Carrizo. Report HSA_CAP_DOORBELL_TYPE_PRE_1_0 on Tonga ASICs. v2: Added #include to kfd_crat.c to make it compile Signed-off-by: Harish Kasiviswanathan Signed-off-by: Ben Goz Signed-off-by: Amber Lin Signed-off-by: Jay Cornwall Signed-off-by: Kent Russell Signed-off-by: Felix Kuehling Acked-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Add topology support for CPUs

2017-12-09T04:08:58Z

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.

drm/amdkfd: Fix sibling_map[] size

2017-12-09T04:08:57Z

Change kfd_cache_properties.sibling_map[256] to kfd_cache_properties.sibling_map[32]. Since, CRAT uses bitmap for sibling_map, it is more efficient to use bitmap in the kfd structure also.
