在 Vulkan 中,存在两种基本类型的内存:主机内存和设备内存。Vulkan 操作的所有资源都必须由设备内存支持,而管理这些内存是应用程序的职责。此外,内存还用于在主机上存储数据结构。Vulkan 也为应用程序提供了管理此类内存的途径。在本章中,你将学习通过哪些机制来管理 Vulkan 使用的内存。 Host Memory Management Whenever...
Sub-allocation is considered to be a first class approach when working in Vulkan. There are certainly cases where one doesn’t need to use it (e.g. very large 3D volume textures). However, the fact that Vulkan provides us with this flexible and granular approach to memory management, means...
In addition, some regions ofthe physical memory attached to each processor might be accessible to the other processor or processors in the system. 当Vulkan 设备对数据进行操作时,数据必须存储在设备内存中。这是设备可以访问的内存。在 Vulkan 系统中,存在四类内存。有些系统可能仅具备其中的一部分类型,而...
resources: Uniform Buffer,Dynamic VB CPU, GPU 都可见, 频繁write ---这种通常用nbuffe缓存(gl下 避免同步map 会卡住 避免invalidmap会复制 ghost,vulkan用coherent自动处理了) Texture, IB,VB,Const Buffer CPU只写一次 CPU GPU可见---这种资源设置成write only 就不需要cache ,cpu不要读它 Framebuffer 仅GP...

This blog post discusses recent improvements and additions to the memory management interface of our Vulkan implementation, based on collaborating with game developers porting their games to Vulkan.Host-local memory types (in “GPU accessible system memory”) to allow applications to put buffers, ...
Vulkan Memory Allocator v3.1, with many fixes and improvements, is out now! VMA V3.1 gathers fixes and improvements, mostly GitHub issues/PRs, including improved compatibility with various compilers and GPUs. Memory Management in the APEX Engine – Digital Dragons 2022 ...
This talk at Vulkanised 2023 covers how to use the Radeon Developer Tool Suite (RDTS) to optimize games using RADV and Steam Deck. Memory Management in the APEX Engine – Digital Dragons 2022 This talk is a joint-presentation with Avalanche Studios Group explaining how their in-house APEX ...
