## Name

VkPhysicalDevicePushConstantBankPropertiesNV - Structure describing push constant bank properties

Loading… please wait.

## C Specification

The `VkPhysicalDevicePushConstantBankPropertiesNV` structure is defined as:

    // Provided by VK_NV_push_constant_bank
    typedef struct VkPhysicalDevicePushConstantBankPropertiesNV {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           maxGraphicsPushConstantBanks;
        uint32_t           maxComputePushConstantBanks;
        uint32_t           maxGraphicsPushDataBanks;
        uint32_t           maxComputePushDataBanks;
    } VkPhysicalDevicePushConstantBankPropertiesNV;

## Members

This structure describes the following implementation-dependent limits:

## Description

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `maxGraphicsPushConstantBanks` indicates the maximum number of push constant banks supported for graphics pipelines when used with non-descriptor heap scenarios.

- `maxComputePushConstantBanks` indicates the maximum number of push constant banks supported for compute pipelines when used with non-descriptor heap scenarios.

- `maxGraphicsPushDataBanks` indicates the maximum number of push data banks supported for graphics pipelines when using descriptor heaps.

- `maxComputePushDataBanks` indicates the maximum number of push data banks supported for compute pipelines when using descriptor heaps.

If the `VkPhysicalDevicePushConstantBankPropertiesNV` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Note | The number of banks available for descriptor heap usage (`maxGraphicsPushDataBanks` and `maxComputePushDataBanks`) is equal or greater than the number of banks available for non-descriptor heap usage (`maxGraphicsPushConstantBanks` and `maxComputePushConstantBanks`). For graphics shaders, both descriptor heap and non-descriptor heap limits are greater than 1. For compute shaders, the number of banks is equal to or greater than 1.

Valid Usage (Implicit)

- VUID-VkPhysicalDevicePushConstantBankPropertiesNV-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PUSH_CONSTANT_BANK_PROPERTIES_NV
