2021-01-15	vulkan_memory_allocator: Add "download" memory usage hint	ReinUsesLisp	1	-15/+27
	Allow users of the allocator to hint memory usage for downloads. This removes the non-descriptive boolean passed for "host visible" or not host visible memory commits, and uses an enum to hint device local, upload and download usages.
2021-01-15	renderer_vulkan: Rename Vulkan memory manager to memory allocator	ReinUsesLisp	1	-4/+4
	"Memory manager" collides with the guest GPU memory manager, and a memory allocator sounds closer to what the abstraction aims to be.
2021-01-15	vk_memory_manager: Improve memory manager and its API	ReinUsesLisp	1	-48/+58
	Fix a bug where the memory allocator could leave gaps between commits. To fix this the allocation algorithm was reworked, although it's still short in number of lines of code. Rework the allocation API to self-contained movable objects instead of naively using an unique_ptr to do the job for us. Remove the VK prefix.
2021-01-04	renderer_vulkan: Move device abstraction to vulkan_common	ReinUsesLisp	1	-1/+1

2021-01-03	renderer_vulkan: Rename VKDevice to Device	ReinUsesLisp	1	-1/+1
	The "VK" prefix predates the "Vulkan" namespace. It was carried around the codebase for consistency. "VKDevice" currently is a bad alias with "VkDevice" (only an upcase character of difference) that can cause confusion. Rename all instances of it.
2020-12-31	vulkan_common: Rename renderer_vulkan/wrapper.h to vulkan_common/vulkan_wrapper.h	ReinUsesLisp	1	-1/+1
	Allows sharing Vulkan wrapper code between different rendering backends.
2020-09-19	renderer_vulkan: Make unconditional use of VK_KHR_timeline_semaphore	ReinUsesLisp	1	-33/+16
	This reworks how host<->device synchronization works on the Vulkan backend. Instead of "protecting" resources with a fence and signalling these as free when the fence is known to be signalled by the host GPU, use timeline semaphores. Vulkan timeline semaphores allow use to work on a subset of D3D12 fences. As far as we are concerned, timeline semaphores are a value set by the host or the device that can be waited by either of them. Taking advantange of this, we can have a monolithically increasing atomic value for each submission to the graphics queue. Instead of protecting resources with a fence, we simply store the current logical tick (the atomic value stored in CPU memory). When we want to know if a resource is free, it can be compared to the current GPU tick. This greatly simplifies resource management code and the free status of resources should have less false negatives. To workaround bugs in validation layers, when these are attached there's a thread waiting for timeline semaphores.
2020-07-17	vk_staging_buffer_pool: Make use of designated initializers where applicable	Lioncash	1	-13/+12

2020-04-22	vk_memory_manager: Remove unified memory model flag	ReinUsesLisp	1	-6/+3
	All drivers (even Intel) seem to have a device local memory type that is not host visible. Remove this flag so all devices follow the same path. This fixes a crash when trying to map to host device local memory on integrated devices.
2020-04-22	vk_rasterizer: Add lazy default buffer maker and use it for empty buffers	ReinUsesLisp	1	-1/+1
	Introduce a default buffer getter that lazily constructs an empty buffer. This is intended to match OpenGL's buffer 0. Use this for disabled vertex and uniform buffers. While we are at it, include vertex buffer usages for staging buffers to silence validation errors.
2020-04-11	renderer_vulkan: Drop Vulkan-Hpp	ReinUsesLisp	1	-9/+16

2020-03-19	vk_staging_buffer_pool: Silence unused constant warning	ReinUsesLisp	1	-1/+1

2020-03-06	vk_rasterizer: Support disabled uniform buffers	ReinUsesLisp	1	-1/+2

2019-12-25	vk_staging_buffer_pool: Add a staging pool for temporary operations	ReinUsesLisp	1	-0/+127
	The job of this abstraction is to provide staging buffers for temporary operations. Think of image uploads or buffer uploads to device memory. It automatically deletes unused buffers.
