2017-12-08drm/amdkfd: Fix sibling_map[] sizeHarish Kasiviswanathan2-10/+14
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.

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.

2017-12-08drm/amdkfd: Decouple CRAT parsing from device list updateHarish Kasiviswanathan4-79/+132
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.

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.
