C Specification
The list of Linux DRM format modifiers
compatible with a VkFormat can be obtained by adding a
VkDrmFormatModifierPropertiesList2EXT structure to the pNext
chain of VkFormatProperties2.
The VkDrmFormatModifierPropertiesList2EXT structure is defined as:
// Provided by VK_EXT_image_drm_format_modifier with VK_KHR_format_feature_flags2 or VK_VERSION_1_3
typedef struct VkDrmFormatModifierPropertiesList2EXT {
VkStructureType sType;
void* pNext;
uint32_t drmFormatModifierCount;
VkDrmFormatModifierProperties2EXT* pDrmFormatModifierProperties;
} VkDrmFormatModifierPropertiesList2EXT;
Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
drmFormatModifierCountis an inout parameter related to the number of modifiers compatible with theformat, as described below. -
pDrmFormatModifierPropertiesis eitherNULLor a pointer to an array of VkDrmFormatModifierProperties2EXT structures.
Description
If pDrmFormatModifierProperties is NULL, the number of modifiers
compatible with the queried format is returned in
drmFormatModifierCount.
Otherwise, the application must set drmFormatModifierCount to the
length of the array pDrmFormatModifierProperties; the function will
write at most drmFormatModifierCount elements to the array, and will
return in drmFormatModifierCount the number of elements written.
Among the elements in array pDrmFormatModifierProperties, each
returned drmFormatModifier must be unique.
Among the elements in array pDrmFormatModifierProperties, the bits
reported in drmFormatModifierTilingFeatures must include the bits
reported in the corresponding element of
VkDrmFormatModifierPropertiesListEXT::pDrmFormatModifierProperties.
