Unsafe version of: GetDynamicRenderingTilePropertiesQCOM

Unsafe version of: GetFramebufferTilePropertiesQCOM

Parameters

pPropertiesCount:long

a pointer to an integer related to the number of tile properties available or queried, as described below.

Get the properties when using dynamic rendering.

C Specification

To query the tile properties when using dynamic rendering, call:

VkResult vkGetDynamicRenderingTilePropertiesQCOM(
    VkDevice                                    device,
    const VkRenderingInfo*                      pRenderingInfo,
    VkTilePropertiesQCOM*                       pProperties);

Valid Usage (Implicit)

• device must be a valid VkDevice handle
• pRenderingInfo must be a valid pointer to a valid VkRenderingInfo structure
• pProperties must be a valid pointer to a VkTilePropertiesQCOM structure

Return Codes

On success, this command returns

• SUCCESS

VkRenderingInfo, VkTilePropertiesQCOM

Parameters

device:VkDevice

a logical device associated with the render pass.

pRenderingInfo:VkRenderingInfo

a pointer to the VkRenderingInfo structure specifying details of the render pass instance in dynamic rendering.

pProperties:VkTilePropertiesQCOM

a pointer to a VkTilePropertiesQCOM structure in which the properties are returned.

Annotations

@NativeType:VkResult

Get tile properties from the attachments in framebuffer.

C Specification

To query the tile properties from the attachments in framebuffer, call:

VkResult vkGetFramebufferTilePropertiesQCOM(
    VkDevice                                    device,
    VkFramebuffer                               framebuffer,
    uint32_t*                                   pPropertiesCount,
    VkTilePropertiesQCOM*                       pProperties);

Description

If pProperties is NULL, then the number of tile properties available is returned in pPropertiesCount. Otherwise, pPropertiesCount must point to a variable set by the user to the number of elements in the pProperties array, and on return the variable is overwritten with the number of properties actually written to pProperties. If pPropertiesCount is less than the number of tile properties available, at most pPropertiesCount structures will be written, and INCOMPLETE will be returned instead of SUCCESS, to indicate that not all the available properties were returned.

The number of tile properties available is determined by the number of merged subpasses, and each tile property is associated with a merged subpass. There will be at most as many properties as there are subpasses within the render pass. To obtain the tile properties for a given merged subpass, the pProperties array can be indexed using the postMergeIndex value provided in VkRenderPassSubpassFeedbackInfoEXT.

Valid Usage (Implicit)

• device must be a valid VkDevice handle
• framebuffer must be a valid VkFramebuffer handle
• pPropertiesCount must be a valid pointer to a uint32_t value
• If the value referenced by pPropertiesCount is not 0, and pProperties is not NULL, pProperties must be a valid pointer to an array of pPropertiesCount VkTilePropertiesQCOM structures
• framebuffer must have been created, allocated, or retrieved from device

Return Codes

On success, this command returns

• SUCCESS
• INCOMPLETE

Parameters

device:VkDevice

a logical device associated with the framebuffer.

framebuffer:long

a handle of the framebuffer to query.

pPropertiesCount:IntBuffer

a pointer to an integer related to the number of tile properties available or queried, as described below.

pProperties:VkTilePropertiesQCOM.Buffer

either NULL or a pointer to an array of VkTilePropertiesQCOM structures.
