Detailed Description

class KDGpu::Adapter;

Adapter is a representation of a physical hardware device.

See:

• KDGpu::Instance::createDefaultDevice
• KDGpu::Instance::adapters
• KDGpu::Instance::selectAdapter
• KDGpu::Device

Adapter instances are provided by the Instance. The Adapter is used to query what the underlying physical hardware supports. In turn, a logical Device can be created from the Adapter.

using namespace KDGpu;

Adapter *selectedAdapter = instance.selectAdapter(AdapterDeviceType::Default);
if (!selectedAdapter)
    return;

auto queueTypes = selectedAdapter->queueTypes();
const bool hasGraphicsAndCompute = queueTypes[0].supportsFeature(QueueFlags(QueueFlagBits::GraphicsBit) | QueueFlags(QueueFlagBits::ComputeBit));
const bool supportsPresentation = selectedAdapter->supportsPresentation(surface, 0);

if (!supportsPresentation || !hasGraphicsAndCompute)
    return;
