operator==()

bool Diligent::AdapterMemoryInfo::operator== ( const AdapterMemoryInfo & RHS ) const

inlineconstexpr

Comparison operator tests if two structures are equivalent.

Parameters

[in]

RHS

- reference to the structure to perform comparison with

Returns

• True if all members of the two structures are equal.
• False otherwise.

Member Data Documentation

HostVisibleMemory

Uint64 Diligent::AdapterMemoryInfo::HostVisibleMemory = 0

The amount of host-visible memory that can be accessed by CPU and is visible by GPU, in bytes.

Host-visible memory is where USAGE_DYNAMIC and USAGE_STAGING resources are typically allocated.

LocalMemory

Uint64 Diligent::AdapterMemoryInfo::LocalMemory = 0

The amount of local video memory that is inaccessible by CPU, in bytes.

Device-local memory is where USAGE_DEFAULT and USAGE_IMMUTABLE resources are typically allocated.

On some devices it may not be possible to query the memory size, in which case all memory sizes will be zero.

MaxMemoryAllocation

Uint64 Diligent::AdapterMemoryInfo::MaxMemoryAllocation = 0

Maximum size of a continuous memory block.

This is the maximum allowed size of non-sparse resources (IBuffer, ITexture, IDeviceMemory, IBottomLevelAS or ITopLevelAS).

MemorylessTextureBindFlags

BIND_FLAGS Diligent::AdapterMemoryInfo::MemorylessTextureBindFlags = BIND_NONE

Indicates if device supports color and depth attachments in on-chip memory.

If supported, it will be combination of the following flags: Diligent::BIND_RENDER_TARGET, Diligent::BIND_DEPTH_STENCIL, Diligent::BIND_INPUT_ATTACHMENT.

UnifiedMemory

Uint64 Diligent::AdapterMemoryInfo::UnifiedMemory = 0

The amount of unified memory that can be directly accessed by both CPU and GPU, in bytes.

Unified memory is where USAGE_UNIFIED resources are typically allocated, but resources with other usages may be allocated as well if there is no corresponding memory type.
