ludus::graphics::rhi::DeviceDescription¶

Struct

Copied device admission requirements. Unsupported required workloads fail before startup. Preferences never cause failure or enable unimplemented operations. No pins are upgraded.

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/device.h

Fields¶

Selection¶

BackendSelection ludus::graphics::rhi::DeviceDescription::Selection = BackendSelection::Auto

Native accepts Auto; browser supports Auto or a forced browser backend.

Related types: BackendSelection

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/device.h

Limits¶

DeviceRequirements ludus::graphics::rhi::DeviceDescription::Limits

Minimum effective fullscreen limits; checked on each backend attempt.

Related types: DeviceRequirements

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/device.h

Required¶

DeviceFeatures ludus::graphics::rhi::DeviceDescription::Required { .FullscreenRaster = true }

Required workloads; unimplemented operations reject before startup, while the portable raster profile is verified on each negotiated backend before Ready.

Related types: DeviceFeatures

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/device.h

Preferred¶

DeviceFeatures ludus::graphics::rhi::DeviceDescription::Preferred

Optional workloads; inspect Enabled after Ready rather than assuming availability.

Related types: DeviceFeatures

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/device.h

Storage¶

StorageLimits ludus::graphics::rhi::DeviceDescription::Storage

R6 general resource/plan maxima and memory budgets, copied before startup. Growth is owner-thread only between frames; enabled maxima stay immutable until shutdown.

Related types: StorageLimits

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/device.h

EnableGpuTiming¶

bool ludus::graphics::rhi::DeviceDescription::EnableGpuTiming = false

Request optional GPU frame timing (R7); absent backend support never fails admission.

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/device.h

RequiredProfile¶

DeviceProfileRequirements ludus::graphics::rhi::DeviceDescription::RequiredProfile

Copied profile constraints, checked on every enabled backend attempt before Ready. Nonzero raster/compute constraints imply admission of that workload.

Related types: DeviceProfileRequirements

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/device.h

PreferredProfile¶

DeviceProfileRequirements ludus::graphics::rhi::DeviceDescription::PreferredProfile

Optional constraints; unmet values do not prevent Ready or elevate backend limits.
