		enum xrt_swapchain_usage_bits	bits
	)

Returns the usage bits for a given selected format and usage.

For color formats always adds:

VK_IMAGE_USAGE_SAMPLED_BIT for compositor reading in shaders.

For depth & stencil formats always adds:

VK_IMAGE_USAGE_SAMPLED_BIT for compositor reading in shaders.

For depth formats always adds:

VK_IMAGE_USAGE_SAMPLED_BIT for compositor reading in shaders.

For stencil formats always adds:

VK_IMAGE_USAGE_SAMPLED_BIT for compositor reading in shaders.

◆ vk_csci_get_image_view_aspect()

VkImageAspectFlags vk_csci_get_image_view_aspect	(	VkFormat	format,
		enum xrt_swapchain_usage_bits	bits
	)

For images views created by the compositor to sample the images, what aspect should be set.

For color it's the color, for depth and stencil it's only depth as both are disallowed by the Vulkan spec, for depth only depth, and for stencil only it's stencil.

◆ vk_fill_in_has_instance_extensions()

void vk_fill_in_has_instance_extensions	(	struct vk_bundle *	vk,
		struct u_string_list *	ext_list
	)

Fills in has_* in vk_bundle given a string of prefiltered instance extensions.

◆ vk_format_feature_flag_string()

XRT_CHECK_RESULT const char * vk_format_feature_flag_string	(	VkFormatFeatureFlagBits	bits,
		bool	null_on_unknown
	)

Returns the format feature flag if one valid bit is set, if multiple bits are set, will return 'MULTIPLE BIT SET'.

◆ vk_image_usage_flag_string()

XRT_CHECK_RESULT const char * vk_image_usage_flag_string	(	VkImageUsageFlagBits	bits,
		bool	null_on_unknown
	)

Returns the image usage flag if one valid bit is set, if multiple bits are set, will return 'MULTIPLE BIT SET'.

◆ vk_print_external_handles_info()

void vk_print_external_handles_info	(	struct vk_bundle *	vk,
		enum u_logging_level	log_level
	)

Print external handle features to the logger at the given logging level, if the vk_bundle has that level enabled.

◆ vk_print_features_info()

void vk_print_features_info	(	struct vk_bundle *	vk,
		enum u_logging_level	log_level
	)

Print device features to the logger at the given logging level, if the vk_bundle has that level enabled.

◆ vk_print_swapchain_create_info()

void vk_print_swapchain_create_info	(	struct vk_bundle *	vk,
		VkSwapchainCreateInfoKHR *	i,
		enum u_logging_level	log_level
	)

Print a VkSwapchainCreateInfoKHR, used to log during creation.

◆ vk_surface_transform_flag_string()

XRT_CHECK_RESULT const char * vk_surface_transform_flag_string	(	VkSurfaceTransformFlagBitsKHR	bits,
		bool	null_on_unknown
	)

Returns the surface transform flag if one valid bit is set, if multiple bits are set, will return 'MULTIPLE BIT SET'.

◆ xrt_swapchain_usage_flag_string()

XRT_CHECK_RESULT const char * xrt_swapchain_usage_flag_string	(	enum xrt_swapchain_usage_bits	bits,
		bool	null_on_unknown
	)

Returns xrt swapchain_usage flag if one valid bit is set, if multiple bits are set, will return 'MULTIPLE BIT SET'.
