Used to query physical GPU details, like features, capabilities, memory size, etc. -- **VkDevice**: The “logical” GPU context that you actually execute things on. -- **VkBuffer**: A chunk of GPU visible memory. -- **VkImage**: A texture you can write to and read from. -- **VkPipeline**: Holds the state of the gpu needed to draw. For example: shaders, rasterization options, depth settings. -- **VkRenderPass**: Holds information about the images you are rendering into. All drawing commands have to be done inside a renderpass. Only used in legacy vkguide. -- **VkFrameBuffer**: Holds the target images for a renderpass. Only used in legacy vkguide. -- **VkCommandBuffer**: Encodes GPU commands. All execution that is performed on the GPU itself (not in the driver) has to be encoded in a VkCommandBuffer. -- **VkQueue**: Execution “port” for commands. GPUs will have a set of queues with different properties. Some allow only graphics commands, others only allow memory commands, etc. Command buffers are executed by submitting them into a queue, which will copy the rendering commands onto the GPU for execution. -- **VkDescriptorSet**: Holds the binding information that connects shader inputs to data such as VkBuffer resources and VkImage textures. Think of it as a set of gpu-side pointers that you bind once. -- **VkSwapchainKHR**: Holds the images for the screen. It allows you to render things into a visible window. The KHR suffix shows that it comes from an extension, which in this case is VK_KHR_swapchain. -- **VkSemaphore**: Synchronizes GPU to GPU execution of commands. Used for syncing multiple command buffer submissions one after another. -- **VkFence**: Synchronizes GPU to CPU execution of commands. Used to know if a command buffer has finished being executed on the GPU. diff --git a/src/renderer/backends/vulkan_helpers.h b/src/renderer/backends/vulkan_helpers.h deleted file mode 100644 index 23666c6..0000000 --- a/src/renderer/backends/vulkan_helpers.h +++ /dev/null @@ -1,199 +0,0 @@ -#pragma once - -#include <assert.h> -#include <vulkan/vulkan.h> -#include <vulkan/vulkan_core.h> - -#include "darray.h" -#include "defines.h" -#include "log.h" -#include "str.h" - -#define VULKAN_PHYS_DEVICE_MAX_EXTENSION_NAMES 36 - -DECL_TYPED_ARRAY(const char*, cstr) - -static void plat_get_required_extension_names(cstr_darray* extensions) { -#ifdef CEL_PLATFORM_LINUX - cstr_darray_push(extensions, "VK_KHR_xcb_surface"); -#endif -} - -// TODO(omni): port to using internal assert functions -#define VK_CHECK(vulkan_expr) \ - do { \ - VkResult res = vulkan_expr; \ - if (res != VK_SUCCESS) { \ - ERROR_EXIT("Vulkan error: %u (%s:%d)", res, __FILE__, __LINE__); \ - } \ - } while (0) - -// TODO: typedef struct vk_debugger {} vk_debugger; - -typedef struct vulkan_physical_device_requirements { - bool graphics; - bool present; - bool compute; - bool transfer; - str8 device_ext_names[VULKAN_PHYS_DEVICE_MAX_EXTENSION_NAMES]; - size_t device_ext_name_count; - bool sampler_anistropy; - bool discrete_gpu; -} vulkan_physical_device_requirements; - -#define VULKAN_MAX_DEFAULT 32 - -typedef struct vulkan_swapchain_support_info { - VkSurfaceCapabilitiesKHR capabilities; - VkSurfaceFormatKHR formats[VULKAN_MAX_DEFAULT]; - u32 format_count; - VkPresentModeKHR present_modes[VULKAN_MAX_DEFAULT]; - u32 mode_count; -} vulkan_swapchain_support_info; - -VKAPI_ATTR VkBool32 VKAPI_CALL vk_debug_callback( - VkDebugUtilsMessageSeverityFlagBitsEXT severity, VkDebugUtilsMessageTypeFlagsEXT flags, - const VkDebugUtilsMessengerCallbackDataEXT* callback_data, void* user_data); - -static void vulkan_device_query_swapchain_support(VkPhysicalDevice device, VkSurfaceKHR surface, - vulkan_swapchain_support_info* out_support_info) { - // TODO: add VK_CHECK to these calls! - - // Surface capabilities - vkGetPhysicalDeviceSurfaceCapabilitiesKHR(device, surface, &out_support_info->capabilities); - - // Surface formats - vkGetPhysicalDeviceSurfaceFormatsKHR(device, surface, &out_support_info->format_count, - 0); // Get number of formats - if (out_support_info->format_count > 0) { - vkGetPhysicalDeviceSurfaceFormatsKHR(device, surface, &out_support_info->format_count, - out_support_info->formats); - } - - // Present Modes - vkGetPhysicalDeviceSurfacePresentModesKHR(device, surface, &out_support_info->mode_count, - 0); // Get number of formats - if (out_support_info->mode_count > 0) { - vkGetPhysicalDeviceSurfacePresentModesKHR(device, surface, &out_support_info->mode_count, - out_support_info->present_modes); - } -} - -static VkSurfaceFormatKHR choose_swapchain_format( - vulkan_swapchain_support_info* swapchain_support) { - assert(swapchain_support->format_count > 0); - // find a format - for (u32 i = 0; i < swapchain_support->format_count; i++) { - VkSurfaceFormatKHR format = swapchain_support->formats[i]; - if (format.format == VK_FORMAT_B8G8R8A8_SRGB && - format.colorSpace == VK_COLOR_SPACE_SRGB_NONLINEAR_KHR) { - return format; - } - } - return swapchain_support->formats[0]; -} - -// static bool physical_device_meets_requirements( -// VkPhysicalDevice device, VkSurfaceKHR surface, const VkPhysicalDeviceProperties* properties, -// const VkPhysicalDeviceFeatures* features, -// const vulkan_physical_device_requirements* requirements, -// vulkan_physical_device_queue_family_info* out_queue_info, -// vulkan_swapchain_support_info* out_swapchain_support) { -// // TODO: pass in an arena - -// out_queue_info->graphics_family_index = -1; -// out_queue_info->present_family_index = -1; -// out_queue_info->compute_family_index = -1; -// out_queue_info->transfer_family_index = -1; - -// if (requirements->discrete_gpu) { -// if (properties->deviceType != VK_PHYSICAL_DEVICE_TYPE_DISCRETE_GPU) { -// TRACE("Device is not a physical GPU.
