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
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
drmFormatModifierCount
is an inout parameter related to the number of modifiers compatible with theformat
, as described below. -
pDrmFormatModifierProperties
is eitherNULL
or 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
.
