NAME

       PAPI_get_dev_type_attr - returns device type attributes

SYNOPSIS

Detailed Description

       Return values
           ENOSUPP invalid attribute

       Parameters
           handle opaque handle for device, obtained through PAPI_enum_dev_type
           attr device type attribute to query
           val value of the requested device type attribute

       Example:

           typedef enum {
               PAPI_DEV_TYPE_ATTR__INT_PAPI_ID,    // PAPI defined device type id
               PAPI_DEV_TYPE_ATTR__INT_VENDOR_ID,  // Vendor defined id
               PAPI_DEV_TYPE_ATTR__CHAR_NAME,      // Vendor name
               PAPI_DEV_TYPE_ATTR__INT_COUNT,      // Devices of that type and vendor
               PAPI_DEV_TYPE_ATTR__CHAR_STATUS,    // Status string for the device type
           } PAPI_dev_type_attr_e;

           typedef enum {
               PAPI_DEV_TYPE_ID__CPU,   // Device id for CPUs
               PAPI_DEV_TYPE_ID__CUDA,  // Device id for Nvidia GPUs
               PAPI_DEV_TYPE_ID__ROCM,  // Device id for AMD GPUs
           } PAPI_dev_type_id_e;

           void *handle;
           int id;
           int enum_modifier = PAPI_DEV_TYPE_ENUM__ALL;
           while (PAPI_OK == PAPI_enum_dev_type(enum_modifier, &handle)) {
               PAPI_get_dev_type_attr(handle, PAPI_DEV_TYPE_ATTR__INT_PAPI_ID, &id);
               switch (id) {
                   case PAPI_DEV_TYPE_ID__CPU:
                       // query cpu attributes
                       break;
                   case PAPI_DEV_TYPE_ID__CUDA:
                       // query nvidia gpu attributes
                       break;
                   case PAPI_DEV_TYPE_ID__ROCM:
                       // query amd gpu attributes
                       break;
                   default: ...
               }
           }

            PAPI_get_dev_type_attr() allows the user to query all device type attributes. It
           takes a device type handle, returned by PAPI_enum_dev_type, and an attribute to be
           queried for the device type and returns the attribute value.
