VK_FORMAT_FEATURE_TRANSFER_[SRC|DST]_BIT_KHR is a flag value of the
VkFormatFeatureFlagBits enum that can only be hold and checked against
the linearTilingFeatures or optimalTilingFeatures members of the
VkFormatProperties struct but not the bufferFeatures member.
>From the Vulkan® 1.0.51, with the VK_KHR_maintenance1 extension,
section 32.3.2 docs for VkFormatProperties:
"* linearTilingFeatures is a bitmask of VkFormatFeatureFlagBits
specifying features supported by images created with a tiling
parameter of VK_IMAGE_TILING_LINEAR.
* optimalTilingFeatures is a bitmask of VkFormatFeatureFlagBits
specifying features supported by images created with a tiling
parameter of VK_IMAGE_TILING_OPTIMAL.
* bufferFeatures is a bitmask of VkFormatFeatureFlagBits
specifying features supported by buffers."
...
Bits which can be set in the VkFormatProperties features
linearTilingFeatures, optimalTilingFeatures, and bufferFeatures
are:
typedef enum VkFormatFeatureFlagBits {
...
VK_FORMAT_FEATURE_TRANSFER_SRC_BIT_KHR = 0x00004000,
VK_FORMAT_FEATURE_TRANSFER_DST_BIT_KHR = 0x00008000,
...
} VkFormatFeatureFlagBits;
...
The following bits may be set in linearTilingFeatures and
optimalTilingFeatures, specifying that the features are supported
by images or image views created with the queried
vkGetPhysicalDeviceFormatProperties::format:
...
* VK_FORMAT_FEATURE_TRANSFER_SRC_BIT_KHR specifies that an image
can be used as a source image for copy commands.
* VK_FORMAT_FEATURE_TRANSFER_DST_BIT_KHR specifies that an image
can be used as a destination image for copy commands and clear
commands."
