PAPI_get_dev_type_attr(3)

🌸 NAME 🌸

Welcome to the PAPI manual, bestie — this is the page for PAPI_get_dev_type_attr (section 3, iykyk), and it returns device type attributes. 💖

✨ SYNOPSIS ✨

💖 Detailed Description 💖

🌈 Return values 🌈

• ENOSUPP — invalid attribute. That's the return-value tea. 🍵

🎀 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: ...
    }
}

Okay so PAPI_get_dev_type_attr() literally allows you to query all device type attributes. You pass it a device type handle (the kind returned by PAPI_enum_dev_type) and an attribute to be queried for that device type, and it returns the attribute value. That's the whole arc, no cap. 💅
