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. Signed-off-by:

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. Signed-off-by:

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 <linux/pci.h> to kfd_crat.c to make it compile Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

Modify kfd_topology_enum_kfd_devices(..) function to support non-GPU nodes. The function returned NULL when it encountered non-GPU (say CPU) nodes. This caused kfd_ioctl_create_event and kfd_init_apertures to fail for Intel + Tonga. kfd_topology_enum_kfd_devices will now parse all the nodes and return valid kfd_dev for nodes with GPU.

Currently, CRAT parsing is intertwined with topology_device_list and hence repeated calls to kfd_parse_crat_table() will fail. Decouple kfd_parse_crat_table() and topology_device_list. kfd_parse_crat_table() will parse CRAT and add topology devices to a temporary list temp_topology_device_list and then kfd_topology_update_device_list will move contents from temporary list to master list.

Take CRAT related functions out of kfd_topology.c and place them in kfd_crat.c. This is the initial step of supporting more CRAT features, i.e. creating virtual CRAT table for KFD devices without CRAT. v2: Minor cleanup that was missed previously because code moved around Signed-off-by:

Kobject created using kobject_create_and_add() can be freed using kobject_put() when there is no referenece any more. However, kobject memory allocated with kzalloc() has to set up a release callback in order to free it when the counter decreases to 0. Otherwise it causes memory leak. Signed-off-by:

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.

This will be used to elliminate the use of the process lock for preventing concurrent process destruction. This will simplify lock dependencies between KFD and KGD. This also simplifies the process destruction in a few ways: * Don't allocate work struct dynamically * Remove unnecessary hack that increments mm reference counter * Remove unnecessary process locking during destruction Signed-off-by:

Allow HWS to to execute multiple processes on the hardware concurrently. The number of concurrent processes is limited by the number of VMIDs allocated to the HWS. A module parameter can be used for limiting this further or turn it off altogether (mainly for debugging purposes). Signed-off-by:
