### Vulkan RAII Application Example

Source: https://docs.vulkan.org/tutorial/latest/_attachments/04_logical_device.cpp

A complete C++ example demonstrating a Vulkan application using the RAII wrapper. It includes instance creation, debug callback setup, and the main application run loop. Ensure Vulkan headers and RAII wrappers are correctly included.

```cpp
#include <vulkan/vulkan_raii.hpp>

		extensions.push_back(vk::EXTDebugUtilsExtensionName);
		}

		return extensions;
	}

	static VKAPI_ATTR vk::Bool32 VKAPI_CALL debugCallback(vk::DebugUtilsMessageSeverityFlagBitsEXT severity, vk::DebugUtilsMessageTypeFlagsEXT type, const vk::DebugUtilsMessengerCallbackDataEXT *pCallbackData, void *)
	{
		if (severity == vk::DebugUtilsMessageSeverityFlagBitsEXT::eError || severity == vk::DebugUtilsMessageSeverityFlagBitsEXT::eWarning)
		{
			std::cerr << "validation layer: type " << to_string(type) << " msg: " << pCallbackData->pMessage << std::endl;
		}

		return vk::False;
	}
};

int main()
{
	try
	{
		HelloTriangleApplication app;
		app.run();
	}
	catch (const std::exception &e)
	{
		std::cerr << e.what() << std::endl;
		return EXIT_FAILURE;
	}

	return EXIT_SUCCESS;

### Initialize Performance API, Create Query Pool, Record Queries, and Get Results

Source: https://docs.vulkan.org/spec/latest/appendices/extensions.html

This comprehensive example demonstrates the workflow for using the INTEL Performance Query extension. It covers initializing the API, setting up a query pool for performance queries, recording commands to measure performance, acquiring and applying a performance configuration, and finally retrieving the query results. Ensure necessary setup like device and queue creation, and command buffer submission are handled prior to and after this snippet.

```c
// A previously created device
VkDevice device;

// A queue derived from the device
VkQueue queue;

VkInitializePerformanceApiInfoINTEL performanceApiInfoIntel = {
  VK_STRUCTURE_TYPE_INITIALIZE_PERFORMANCE_API_INFO_INTEL,
  NULL,
  NULL
};

vkInitializePerformanceApiINTEL(
  device,
  &performanceApiInfoIntel);

VkQueryPoolPerformanceQueryCreateInfoINTEL queryPoolIntel = {
  VK_STRUCTURE_TYPE_QUERY_POOL_CREATE_INFO_INTEL,
  NULL,
  VK_QUERY_POOL_SAMPLING_MODE_MANUAL_INTEL,
};

VkQueryPoolCreateInfo queryPoolCreateInfo = {
  VK_STRUCTURE_TYPE_QUERY_POOL_CREATE_INFO,
  &queryPoolIntel,
  0,
  VK_QUERY_TYPE_PERFORMANCE_QUERY_INTEL,
  1,
  0
};

VkQueryPool queryPool;

VkResult result = vkCreateQueryPool(
  device,
  &queryPoolCreateInfo,
  NULL,
  &queryPool);

assert(VK_SUCCESS == result);

// A command buffer we want to record counters on
VkCommandBuffer commandBuffer;

VkCommandBufferBeginInfo commandBufferBeginInfo = {
  VK_STRUCTURE_TYPE_COMMAND_BUFFER_BEGIN_INFO,
  NULL,
  VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT,
  NULL
};

result = vkBeginCommandBuffer(commandBuffer, &commandBufferBeginInfo);

assert(VK_SUCCESS == result);

vkCmdResetQueryPool(
  commandBuffer,
  queryPool,
  0,
  1);

vkCmdBeginQuery(
  commandBuffer,
  queryPool,
  0,
  0);

// Perform the commands you want to get performance information on
// ...

// Perform a barrier to ensure all previous commands were complete before
// ending the query
vkCmdPipelineBarrier(commandBuffer,
  VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT,
  VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT,
  0,
  0,
  NULL,
  0,
  NULL,
  0,
  NULL);

vkCmdEndQuery(
  commandBuffer,
  queryPool,
  0);

result = vkEndCommandBuffer(commandBuffer);

assert(VK_SUCCESS == result);

VkPerformanceConfigurationAcquireInfoINTEL performanceConfigurationAcquireInfo = {
  VK_STRUCTURE_TYPE_PERFORMANCE_CONFIGURATION_ACQUIRE_INFO_INTEL,
  NULL,
  VK_PERFORMANCE_CONFIGURATION_TYPE_COMMAND_QUEUE_METRICS_DISCOVERY_ACTIVATED_INTEL
};

VkPerformanceConfigurationINTEL performanceConfigurationIntel;

result = vkAcquirePerformanceConfigurationINTEL(
  device,
  &performanceConfigurationAcquireInfo,
  &performanceConfigurationIntel);

vkQueueSetPerformanceConfigurationINTEL(queue, performanceConfigurationIntel);

assert(VK_SUCCESS == result);

// Submit the command buffer and wait for its completion
// ...

result = vkReleasePerformanceConfigurationINTEL(
  device,
  performanceConfigurationIntel);

assert(VK_SUCCESS == result);

// Get the report size from metrics-discovery's QueryReportSize

result = vkGetQueryPoolResults(
  device,
  queryPool,
  0, 1, QueryReportSize,
  data, QueryReportSize, 0);

assert(VK_SUCCESS == result);

// The data can then be passed back to metrics-discovery from which
// human readable values can be queried.

```

### Vulkan Instance Creation with Exception Handling

Source: https://docs.vulkan.org/tutorial/latest/03_Drawing_a_triangle/00_Setup/01_Instance.html

Demonstrates creating a Vulkan context, instance, physical device, and device using RAII wrappers and catching potential Vulkan or standard exceptions.

```cpp
    try
    {
        vk::raii::Context context;
        vk::raii::Instance instance(context, vk::InstanceCreateInfo{});
        vk::raii::PhysicalDevice physicalDevice = instance.enumeratePhysicalDevices().front();
        vk::raii::Device device(physicalDevice, vk::DeviceCreateInfo{});

        // Use Vulkan objects
        vk::raii::Buffer buffer(device, vk::BufferCreateInfo{});
    }
    catch (const vk::SystemError& err)
    {
        std::cerr << "Vulkan error: " << err.what() << std::endl;
        return 1;
    }
    catch (const std::exception& err)
    {
        std::cerr << "Error: " << err.what() << std::endl;
        return 1;
    }
```

--------------------------------

### Example: Enumerate Available Performance Counters

Source: https://docs.vulkan.org/features/latest/features/proposals/VK_ARM_performance_counters_by_region.html

Demonstrates the two-step process for enumerating performance counters: first to get the count, then to retrieve the actual counter data.

```c
/* Retrieve the number of counters */
vkEnumeratePhysicalDeviceQueueFamilyPerformanceCountersByRegionARM(physicalDevice, queueFamilyIndex, &counterCount, NULL, NULL);

/* Allocate memory and retrieve the counter IDs and descriptions);
counters = malloc(counterCount * sizeof(VkPerformanceCounterARM));
descriptions = malloc(counterCount * sizeof(VkPerformanceCounterDescriptionARM));
vkEnumeratePhysicalDeviceQueueFamilyPerformanceCountersByRegionARM(physicalDevice, queueFamilyIndex, &counterCount, counters, descriptions);
```

--------------------------------

### Setting up and Using Dynamic Rendering

Source: https://docs.vulkan.org/features/latest/features/proposals/VK_KHR_dynamic_rendering.html

Demonstrates how to configure and use dynamic rendering by defining attachment information and issuing rendering commands. This approach bypasses the need for explicit VkRenderPass objects.

```c
VkRenderingAttachmentInfoKHR colorAttachments[2] = {
    {
        .sType = VK_STRUCTURE_TYPE_RENDERING_ATTACHMENT_INFO_KHR
        .pNext = NULL,
        .imageView = colorImageViews[0],
        .imageLayout = VK_IMAGE_LAYOUT_ATTACHMENT_OPTIMAL_KHR,
        .resolveMode = VK_RESOLVE_MODE_AVERAGE_BIT,
        .resolveImageView = resolveColorImageView,
        .resolveImageLayout = VK_IMAGE_LAYOUT_ATTACHMENT_OPTIMAL_KHR,
        .loadOp = VK_ATTACHMENT_LOAD_OP_CLEAR,
        .storeOp = VK_ATTACHMENT_STORE_OP_DONT_CARE,
        .clearValue = {.color = {.float32 = {0.0f,0.0f,0.0f,0.0f} } }
    }, {
        .sType = VK_STRUCTURE_TYPE_RENDERING_ATTACHMENT_INFO_KHR
        .pNext = NULL,
        .imageView = colorImageViews[1],
        .imageLayout = VK_IMAGE_LAYOUT_ATTACHMENT_OPTIMAL_KHR,
        .resolveMode = VK_RESOLVE_MODE_NONE,
        .loadOp = VK_ATTACHMENT_LOAD_OP_DONT_CARE,
        .storeOp = VK_ATTACHMENT_STORE_OP_STORE
    } };

// A single depth stencil attachment info can be used, but they can also be specified separately.
// When both are specified separately, the only requirement is that the image view is identical.
VkRenderingAttachmentInfoKHR depthStencilAttachment = {
    .sType = VK_STRUCTURE_TYPE_RENDERING_ATTACHMENT_INFO_KHR
    .pNext = NULL,
    .imageView = depthStencilStencilImageView,
    .imageLayout = VK_IMAGE_LAYOUT_ATTACHMENT_OPTIMAL_KHR,
    .resolveMode = VK_RESOLVE_MODE_NONE,
    .loadOp = VK_ATTACHMENT_LOAD_OP_CLEAR,
    .storeOp = VK_ATTACHMENT_STORE_OP_DONT_CARE,
    .clearValue = {.depthStencil = {.depth = 0.0f, .stencil = 0 } } };

VkRenderingInfoKHR renderingInfo = {
    .sType = VK_STRUCTURE_TYPE_RENDERING_INFO_KHR,
    .pNext = NULL,
    .flags = 0,
    .renderArea = { ... },
    .layerCount = 1,
    .colorAttachmentCount = 2,
    .pColorAttachments = colorAttachments,
    .pDepthAttachment = &depthStencilAttachment,
    .pStencilAttachment = &depthStencilAttachment };

vkCmdBeginRenderingKHR(commandBuffer, &renderingInfo);

vkCmdDraw(commandBuffer, ...);

...

vkCmdDraw(commandBuffer, ...);

vkCmdEndRenderingKHR(commandBuffer);
```

--------------------------------

### Record Command Buffer for Dynamic Rendering

Source: https://docs.vulkan.org/tutorial/latest/_attachments/38_ray_tracing.cpp

Records commands into a command buffer, including image layout transitions and setting up attachments for dynamic rendering. This example shows the setup for color and depth attachments.

```cpp
void recordCommandBuffer(uint32_t imageIndex)
{
	auto &commandBuffer = commandBuffers[frameIndex];
	commandBuffer.begin({});
	// Before starting rendering, transition the swapchain image to COLOR_ATTACHMENT_OPTIMAL
	transition_image_layout(
	    swapChainImages[imageIndex],
	    vk::ImageLayout::eUndefined,
	    vk::ImageLayout::eColorAttachmentOptimal,
	    {},                                                        // srcAccessMask (no need to wait for previous operations)
	    vk::AccessFlagBits2::eColorAttachmentWrite,                // dstAccessMask
	    vk::PipelineStageFlagBits2::eColorAttachmentOutput,        // srcStage
	    vk::PipelineStageFlagBits2::eColorAttachmentOutput,        // dstStage
	    vk::ImageAspectFlagBits::eColor);
	// Transition depth image to depth attachment optimal layout
	transition_image_layout(
	    *depthImage,
	    vk::ImageLayout::eUndefined,
	    vk::ImageLayout::eDepthAttachmentOptimal,
	    vk::AccessFlagBits2::eDepthStencilAttachmentWrite,
	    vk::AccessFlagBits2::eDepthStencilAttachmentWrite,
	    vk::PipelineStageFlagBits2::eEarlyFragmentTests | vk::PipelineStageFlagBits2::eLateFragmentTests,
	    vk::PipelineStageFlagBits2::eEarlyFragmentTests | vk::PipelineStageFlagBits2::eLateFragmentTests,
	    vk::ImageAspectFlagBits::eDepth);

vk::ClearValue clearColor = vk::ClearColorValue(0.0f, 0.0f, 0.0f, 1.0f);
vk::ClearValue clearDepth = vk::ClearDepthStencilValue(1.0f, 0);

/* TASK01: Check the setup for dynamic rendering
 * 
 * With dynamic rendering, we specify the image view and load/store operations directly
 * in the vk::RenderingAttachmentInfo structure.
 * This approach eliminates the need for explicit render pass and framebuffer objects,
 * simplifying the code and providing flexibility to change attachments at runtime.
 */

vk::RenderingAttachmentInfo colorAttachmentInfo = {
	    .imageView   = swapChainImageViews[imageIndex],
	    .imageLayout = vk::ImageLayout::eColorAttachmentOptimal,
	    .loadOp      = vk::AttachmentLoadOp::eClear,
	    .storeOp     = vk::AttachmentStoreOp::eStore,
	    .clearValue  = clearColor};

vk::RenderingAttachmentInfo depthAttachmentInfo = {
	    .imageView   = depthImageView,
	    .imageLayout = vk::ImageLayout::eDepthStencilAttachmentOptimal,
	    .loadOp      = vk::AttachmentLoadOp::eClear,
	    .storeOp     = vk::AttachmentStoreOp::eDontCare,
	    .clearValue  = clearDepth};
}
```

### Setting Up SDL2 Window with Vulkan Support

Source: https://docs.vulkan.org/guide/latest/windowing_audio_input.html

Initializes SDL, creates a window with Vulkan support, and retrieves necessary Vulkan extensions. This is the starting point for Vulkan applications using SDL2.

```cpp
#include <SDL2/SDL.h>
#include <SDL2/SDL_vulkan.h>
#include <vulkan/vulkan.h>
#include <iostream>
#include <vector>

int main() {
    // Initialize SDL
    if (SDL_Init(SDL_INIT_VIDEO | SDL_INIT_AUDIO) != 0) {
        std::cerr << "SDL_Init Error: " << SDL_GetError() << std::endl;
        return -1;
    }

    // Create window with Vulkan support
    SDL_Window* window = SDL_CreateWindow(
        "Vulkan SDL2 Window",
        SDL_WINDOWPOS_CENTERED,
        SDL_WINDOWPOS_CENTERED,
        800, 600,
        SDL_WINDOW_VULKAN | SDL_WINDOW_SHOWN
    );

    if (!window) {
        std::cerr << "SDL_CreateWindow Error: " << SDL_GetError() << std::endl;
        SDL_Quit();
        return -1;
    }

    // Get required Vulkan extensions for SDL
    unsigned int extensionCount;
    if (!SDL_Vulkan_GetInstanceExtensions(window, &extensionCount, nullptr)) {
        std::cerr << "Failed to get Vulkan extension count" << std::endl;
        return -1;
    }

    std::vector<const char*> extensions(extensionCount);
    if (!SDL_Vulkan_GetInstanceExtensions(window, &extensionCount, extensions.data())) {
        std::cerr << "Failed to get Vulkan extensions" << std::endl;
        return -1;
    }

    // Create Vulkan instance (not shown)
    VkInstance instance = VK_NULL_HANDLE;
    // ... create instance with extensions ...

    // Create Vulkan surface
    VkSurfaceKHR surface;
    if (!SDL_Vulkan_CreateSurface(window, instance, &surface)) {
        std::cerr << "Failed to create Vulkan surface" << std::endl;
        return -1;
    }

    // Main loop
    bool running = true;
    SDL_Event event;
    while (running) {
        while (SDL_PollEvent(&event)) {
            if (event.type == SDL_QUIT) {
                running = false;
            }
        }

        // Render with Vulkan (not shown)
    }

### Mipmap Generation Loop Setup

Source: https://docs.vulkan.org/tutorial/latest/09_Generating_Mipmaps.html

Initializes mipmap dimensions and sets up a loop to iterate through each mip level that needs to be generated. The loop starts from mip level 1, as level 0 is the source data.

```c++
int32_t mipWidth = texWidth;
int32_t mipHeight = texHeight;

for (uint32_t i = 1; i < mipLevels; i++) {

}

};

// Subpass attachment references
VkAttachmentReference2 colorAttachments[2] = {

        .attachment = 0,
        .layout = VK_IMAGE_LAYOUT_COLOR_ATTACHMENT_OPTIMAL,

        .layout = VK_IMAGE_LAYOUT_COLOR_ATTACHMENT_OPTIMAL,
        .aspectMask = VK_IMAGE_ASPECT_COLOR_BIT,
    },
};

VkAttachmentReference2 depthStencilAttachment = {
    .sType = VK_STRUCTURE_TYPE_ATTACHMENT_REFERENCE_2,
    .attachment = 0,
    .layout = VK_IMAGE_LAYOUT_DEPTH_STENCIL_ATTACHMENT_OPTIMAL,
    .aspectMask = VK_IMAGE_ASPECT_DEPTH_BIT | VK_IMAGE_ASPECT_STENCIL_BIT,

    .stencilResolveMode = VK_RESOLVE_MODE_NONE,
};

// The subpass description where multisampled-render-to-single-sampled rendering is enabled.
VkSubpassDescription2 subpassDescription = {
    .sType = VK_STRUCTURE_TYPE_SUBPASS_DESCRIPTION_2_KHR,
    .pNext = &depthStencilResolve,
    .pipelineBindPoint = VK_PIPELINE_BIND_POINT_GRAPHICS,

### Creating VkDevice with Queue Families

Source: https://docs.vulkan.org/guide/latest/queues.html

This example shows how to configure and create a Vulkan logical device, specifying the queue families and the number of queues to create from each. It prepares VkDeviceQueueCreateInfo structures for transfer and graphics queues.

```cpp
VkDeviceQueueCreateInfo queueCreateInfo[2];
queueCreateInfo[0].queueFamilyIndex = 0; // Transfer
queueCreateInfo[0].queueCount = 1;
queueCreateInfo[1].queueFamilyIndex = 1; // Graphics
queueCreateInfo[1].queueCount = 2;

VkDeviceCreateInfo deviceCreateInfo   = {};
deviceCreateInfo.pQueueCreateInfos    = queueCreateInfo;
deviceCreateInfo.queueCreateInfoCount = 2;

vkCreateDevice(physicalDevice, &deviceCreateInfo, nullptr, &device);
```

### Dynamic Vertex Input State Setup

Source: https://docs.vulkan.org/samples/latest/samples/extensions/vertex_dynamic_state/README.html

Demonstrates setting up a graphics pipeline with a null vertex input state and then dynamically configuring vertex input using the VK_EXT_vertex_input_dynamic_state extension.

```cpp
  VkVertexInputBindingDescription2EXT   vertex_bindings_description_ext = {
  vkb::initializers::vertex_input_binding_description2ext(
	    0,
	    sizeof(Vertex),
	    VK_VERTEX_INPUT_RATE_VERTEX,
	    1);
  }
	VkVertexInputAttributeDescription2EXT vertex_attribute_description_ext[2] = {
  vkb::initializers::vertex_input_attribute_description2ext(
	    0,
	    0,
	    VK_FORMAT_R32G32B32_SFLOAT,
	    offsetof(Vertex, pos)),
  vkb::initializers::vertex_input_attribute_description2ext(
	    0,
	    1,
	    VK_FORMAT_R32G32B32_SFLOAT,
	    offsetof(Vertex, normal);
  }

    graphics_create_info.pVertexInputState = nullptr;

    vkCreateGraphicsPipelines(get_device().get_handle(), VK_NULL_HANDLE, 1,
                              &graphics_create_info, VK_NULL_HANDLE, &pipeline);

/* First set of vertex input dynamic data (Vertex structure) */
		vertex_bindings_description_ext[0].stride  = sizeof(Vertex);
		vertex_attribute_description_ext[1].offset = offsetof(Vertex, normal);
		vkCmdSetVertexInputEXT(draw_cmd_buffer,

```

### Basic Vertex Shader Module

Source: https://docs.vulkan.org/tutorial/latest/03_Drawing_a_triangle/02_Graphics_pipeline_basics/01_Shader_modules.html

This vertex shader defines vertex positions directly within the shader code and outputs them as clip coordinates. It uses SV_VertexID to index into a hardcoded array of positions. Suitable for simple examples where vertex buffer setup is deferred.

```slang
static float2 positions[3] = float2[](
    float2(0.0, -0.5),
    float2(0.5, 0.5),
    float2(-0.5, 0.5)
);

struct VertexOutput {
    float4 sv_position : SV_Position;
};

[shader("vertex")]
VertexOutput vertMain(uint vid : SV_VertexID) {
    VertexOutput output;
    output.sv_position = float4(positions[vid], 0.0, 1.0);
    return output;
}
```

    .pNext = NULL,
    .codedOffset = ... // offset within the image subresource (typically { 0, 0 })
    .codedExtent = ... // extent of decoded picture (typically the video frame size)
    .baseArrayLayer = 0,
    .imageViewBinding = outputImageView
};

VkVideoDecodeInfoKHR decodeInfo = {
    .sType = VK_STRUCTURE_TYPE_VIDEO_DECODE_INFO_KHR,
    .pNext = ... // pointer to codec-specific picture information structure
    .flags = 0,
