gurchetansingh 2d60c08c10 Initial YUV and external memory support (#1467) ... * vulkano: image: improve formatting Ran cargo fmt --all. Should we use clippy too ? * vk_sys: add additional formats This updates the vk formats enum to the header that's on my system (vk 1.2-ish). * vulkano: image: Add NV12 and YV12 support These formats are commonly used as targets for hardware and software video decode. The common case is the swapchain allocator (gralloc in the Android use case) allocates some memory, the video stack decodes to it, and then memory can be composited by Vulkan or sent directly to the display. * vk_sys: update structure types This updates the structure types to a VK 1.2-ish state. Long term, it makes a ton of sense to autogenerate vk-sys to make adding additional features and enumerations easier [1]. For now, we can hand edit. [1] (https://github.com/vulkano-rs/vulkano/issues/89) * vk_sys: add VK_KHR_external_memory_fd bindings This adds some basic external memory features. Most of these features are core in VK1.1. * vulkano: memory: add and use DeviceMemoryBuilder We'll need to: (a) Create exportable memory (b) import from a OS descriptor to create DeviceMemory (c) Also support dedicated allocations The device memory API is becoming rather complicated. Let's use the common builder pattern to simplify this. * vulkano: memory: implement some external features This change is sufficient to create exportable memory and export it. It's only been tested on Linux platforms and depends on Unix file descriptors, so enable it only there for now. Import support will be added later. Support for external buffers and images can also be added later if someone needs it.		2021-01-09 19:02:08 +07:00
