Memeriksa dukungan sumber daya Koordinator Aktivitas

Contoh ini menunjukkan bagaimana aplikasi dapat menggunakan IsActivityCoordinatorResourceSupported untuk mendeteksi dukungan sumber daya sebelum membuat kebijakan. Anda dapat menggunakan IsActivityCoordinatorResourceSupported untuk memeriksa ACTIVITY_COORDINATOR_RESOURCE yang didukung saat runtime.

Periksa contoh dukungan NPU

Contoh berikut menunjukkan cara memeriksa dukungan NPU menggunakan API pemeriksaan kemampuan baru untuk sumber daya. API ini memungkinkan aplikasi untuk memeriksa jenis sumber daya yang didukung pada runtime dan akan kembali true jika sumber daya NPU didukung pada sistem saat ini. Contoh ini membuat kebijakan Koordinator Aktivitas dan menetapkan kondisi sumber daya NPU ke ACTIVITY_COORDINATOR_CONDITION_GOOD jika didukung.

#include <Windows.h>
#include <ActivityCoordinator.h>
#include <wil/resource.h>
#include <apiquery2.h>

// Declare RAII wrappers for the Activity Coordinator policy and subscription.
// These behave like traditional smart pointers and will call their associated
// API cleanup functions when they go out of scope.
using unique_policy = wil::unique_any<
          ACTIVITY_COORDINATOR_POLICY,
          decltype(&DestroyActivityCoordinatorPolicy),
          DestroyActivityCoordinatorPolicy>;

bool
CanUseNpuPolicy()
{
    // Check that the Activity Coordinator feature check API is implemented
    // before calling.
    if (IsApiSetImplemented("ext-ms-win-resourcemanager-activitycoordinator-l1-1-1")) {
        if (IsActivityCoordinatorResourceSupported(ACTIVITY_COORDINATOR_RESOURCE_NPU)) {
            return true;
        }
    }

    return false;
}

int
__cdecl
wmain()
{
    unique_policy policy;

    // Activity Coordinator support for NPUs does not indicate their actual
    // presence on the system. Applications must still detect and target desired
    // hardware using their API or framework of choice.
    //
    // When using system resources not supported by Activity Coordinator, it is
    // recommended that policies always include USER_IDLE in the GOOD condition.
    // This will help minimize the potential for interference with a user's
    // foreground applications utilizing the same resource.
    //
    // The GOOD policy template covers this scenario in addition to other
    // resources that most applications are likely to affect even when targeting
    // dedicated hardware.
    RETURN_IF_FAILED(CreateActivityCoordinatorPolicy(
        ACTIVITY_COORDINATOR_POLICY_TEMPLATE_GOOD,
        &policy));

    if (CanUseNpuPolicy()) {
        RETURN_IF_FAILED(SetActivityCoordinatorPolicyResourceCondition(
            policy.get(),
            ACTIVITY_COORDINATOR_RESOURCE_NPU,
            ACTIVITY_COORDINATOR_CONDITION_GOOD));
    }

    // Proceed to use Activity Coordinator to run opportunistic work. See the
    // example project in the documentation for further details.

    return S_OK;
