HWPM driver uses nested structures and arrays of structures. The IP structure setup logic allocates pointer arrays based on dynamic list of IPs and aperture addresses. This dynamic list is required to search given regops address in less amount of time. However, there is a chance that the number of pointers computed dynamically is huge. And huge amount of memory will be required for the dynamic pointers array, which is impractical. This, this patch modifies ip structure setup and address to aperture conversion logic to use static indexes if the pointer array size is huge. This patch modifies relevant functions to always use static arrays to access instance and aperture structures. If dynamic pointers array is allocated, the patch adds logic to translate dynamic index to static index using inst_index_mask for instances and new added aperture_index for element level structures. Add/update few log message to improve relayed information.
