C Specification

The VkPushConstantRange structure is defined as:

typedef struct VkPushConstantRange {
    VkShaderStageFlags    stageFlags;
    uint32_t              offset;
    uint32_t              size;
} VkPushConstantRange;

Members

  • stageFlags is a set of stage flags describing the shader stages that will access a range of push constants. If a particular stage is not included in the range, then accessing members of that range of push constants from the corresponding shader stage will result in undefined data being read.

  • offset and size are the start offset and size, respectively, consumed by the range. Both offset and size are in units of bytes and must be a multiple of 4. The layout of the push constant variables is specified in the shader.

Description

Valid Usage
  • offset must be less than VkPhysicalDeviceLimits::maxPushConstantsSize

  • offset must be a multiple of 4

  • size must be greater than 0

  • size must be a multiple of 4

  • size must be less than or equal to VkPhysicalDeviceLimits::maxPushConstantsSize minus offset

Valid Usage (Implicit)
