25 * # CategoryGPU
26 *
27 * The GPU API offers a cross-platform way for apps to talk to modern graphics
28 * hardware. It offers both 3D graphics and compute support, in the style of
29 * Metal, Vulkan, and Direct3D 12.
30 *
31 * A basic workflow might be something like this:
32 *
33 * The app creates a GPU device with SDL_CreateGPUDevice(), and assigns it to
34 * a window with SDL_ClaimWindowForGPUDevice()--although strictly speaking you
35 * can render offscreen entirely, perhaps for image processing, and not use a
36 * window at all.
37 *
38 * Next the app prepares static data (things that are created once and used
39 * over and over). For example:
40 *
41 * - Shaders (programs that run on the GPU): use SDL_CreateGPUShader().
42 * - Vertex buffers (arrays of geometry data) and other data rendering will
43 * need: use SDL_UploadToGPUBuffer().
44 * - Textures (images): use SDL_UploadToGPUTexture().
45 * - Samplers (how textures should be read from): use SDL_CreateGPUSampler().
46 * - Render pipelines (precalculated rendering state): use
47 * SDL_CreateGPUGraphicsPipeline()
48 *
49 * To render, the app creates one or more command buffers, with
50 * SDL_AcquireGPUCommandBuffer(). Command buffers collect rendering
51 * instructions that will be submitted to the GPU in batch. Complex scenes can
52 * use multiple command buffers, maybe configured across multiple threads in
53 * parallel, as long as they are submitted in the correct order, but many apps
54 * will just need one command buffer per frame.
55 *
56 * Rendering can happen to a texture (what other APIs call a "render target")
57 * or it can happen to the swapchain texture (which is just a special texture
58 * that represents a window's contents). The app can use
59 * SDL_WaitAndAcquireGPUSwapchainTexture() to render to the window.
60 *
61 * Rendering actually happens in a Render Pass, which is encoded into a
62 * command buffer. One can encode multiple render passes (or alternate between
63 * render and compute passes) in a single command buffer, but many apps might
64 * simply need a single render pass in a single command buffer. Render Passes
65 * can render to up to four color textures and one depth texture
66 * simultaneously. If the set of textures being rendered to needs to change,
67 * the Render Pass must be ended and a new one must be begun.
68 *
69 * The app calls SDL_BeginGPURenderPass(). Then it sets states it needs for
70 * each draw:
71 *
72 * - SDL_BindGPUGraphicsPipeline()
73 * - SDL_SetGPUViewport()
74 * - SDL_BindGPUVertexBuffers()
75 * - SDL_BindGPUVertexSamplers()
76 * - etc
77 *
78 * Then, make the actual draw commands with these states:
79 *
80 * - SDL_DrawGPUPrimitives()
81 * - SDL_DrawGPUPrimitivesIndirect()
82 * - SDL_DrawGPUIndexedPrimitivesIndirect()
83 * - etc
84 *
85 * After all the drawing commands for a pass are complete, the app should call
86 * SDL_EndGPURenderPass(). Once a render pass ends all render-related state is
87 * reset.
88 *
89 * The app can begin new Render Passes and make new draws in the same command
90 * buffer until the entire scene is rendered.
91 *
92 * Once all of the render commands for the scene are complete, the app calls
93 * SDL_SubmitGPUCommandBuffer() to send it to the GPU for processing.
94 *
95 * If the app needs to read back data from texture or buffers, the API has an
96 * efficient way of doing this, provided that the app is willing to tolerate
97 * some latency. When the app uses SDL_DownloadFromGPUTexture() or
98 * SDL_DownloadFromGPUBuffer(), submitting the command buffer with
99 * SDL_SubmitGPUCommandBufferAndAcquireFence() will return a fence handle that
100 * the app can poll or wait on in a thread. Once the fence indicates that the
101 * command buffer is done processing, it is safe to read the downloaded data.
102 * Make sure to call SDL_ReleaseGPUFence() when done with the fence.
103 *
104 * The API also has "compute" support. The app calls SDL_BeginGPUComputePass()
105 * with compute-writeable textures and/or buffers, which can be written to in
106 * a compute shader. Then it sets states it needs for the compute dispatches:
107 *
108 * - SDL_BindGPUComputePipeline()
109 * - SDL_BindGPUComputeStorageBuffers()
110 * - SDL_BindGPUComputeStorageTextures()
111 *
112 * Then, dispatch compute work:
113 *
114 * - SDL_DispatchGPUCompute()
115 *
116 * For advanced users, this opens up powerful GPU-driven workflows.
117 *
118 * Graphics and compute pipelines require the use of shaders, which as
119 * mentioned above are small programs executed on the GPU. Each backend
120 * (Vulkan, Metal, D3D12) requires a different shader format. When the app
121 * creates the GPU device, the app lets the device know which shader formats
122 * the app can provide. It will then select the appropriate backend depending
123 * on the available shader formats and the backends available on the platform.
124 * When creating shaders, the app must provide the correct shader format for
125 * the selected backend. If you would like to learn more about why the API
126 * works this way, there is a detailed
127 * [blog post](https://moonside.games/posts/layers-all-the-way-down/)
128 * explaining this situation.
129 *
130 * It is optimal for apps to pre-compile the shader formats they might use,
131 * but for ease of use SDL provides a separate project,
132 * [SDL_shadercross](https://github.com/libsdl-org/SDL_shadercross)
133 * , for performing runtime shader cross-compilation. It also has a CLI
134 * interface for offline precompilation as well.
135 *
136 * This is an extremely quick overview that leaves out several important
137 * details. Already, though, one can see that GPU programming can be quite
138 * complex! If you just need simple 2D graphics, the
139 * [Render API](https://wiki.libsdl.org/SDL3/CategoryRender)
140 * is much easier to use but still hardware-accelerated. That said, even for
141 * 2D applications the performance benefits and expressiveness of the GPU API
142 * are significant.
143 *
144 * The GPU API targets a feature set with a wide range of hardware support and
145 * ease of portability. It is designed so that the app won't have to branch
146 * itself by querying feature support. If you need cutting-edge features with
147 * limited hardware support, this API is probably not for you.
148 *
149 * Examples demonstrating proper usage of this API can be found
150 * [here](https://github.com/TheSpydog/SDL_gpu_examples)
151 * .
152 *
153 * ## Performance considerations
154 *
155 * Here are some basic tips for maximizing your rendering performance.
156 *
157 * - Beginning a new render pass is relatively expensive. Use as few render
158 * passes as you can.
159 * - Minimize the amount of state changes. For example, binding a pipeline is
160 * relatively cheap, but doing it hundreds of times when you don't need to
161 * will slow the performance significantly.
162 * - Perform your data uploads as early as possible in the frame.
163 * - Don't churn resources. Creating and releasing resources is expensive.
164 * It's better to create what you need up front and cache it.
165 * - Don't use uniform buffers for large amounts of data (more than a matrix
166 * or so). Use a storage buffer instead.
167 * - Use cycling correctly. There is a detailed explanation of cycling further
168 * below.
169 * - Use culling techniques to minimize pixel writes. The less writing the GPU
170 * has to do the better. Culling can be a very advanced topic but even
171 * simple culling techniques can boost performance significantly.
172 *
173 * In general try to remember the golden rule of performance: doing things is
174 * more expensive than not doing things. Don't Touch The Driver!
175 *
176 * ## FAQ
177 *
178 * **Question: When are you adding more advanced features, like ray tracing or
179 * mesh shaders?**
180 *
181 * Answer: We don't have immediate plans to add more bleeding-edge features,
182 * but we certainly might in the future, when these features prove worthwhile,
183 * and reasonable to implement across several platforms and underlying APIs.
184 * So while these things are not in the "never" category, they are definitely
185 * not "near future" items either.
186 *
187 * **Question: Why is my shader not working?**
188 *
189 * Answer: A common oversight when using shaders is not properly laying out
190 * the shader resources/registers correctly. The GPU API is very strict with
191 * how it wants resources to be laid out and it's difficult for the API to
192 * automatically validate shaders to see if they have a compatible layout. See
193 * the documentation for SDL_CreateGPUShader() and
194 * SDL_CreateGPUComputePipeline() for information on the expected layout.
195 *
196 * Another common issue is not setting the correct number of samplers,
197 * textures, and buffers in SDL_GPUShaderCreateInfo. If possible use shader
198 * reflection to extract the required information from the shader
199 * automatically instead of manually filling in the struct's values.
200 *
201 * **Question: My application isn't performing very well. Is this the GPU
202 * API's fault?**
203 *
204 * Answer: No. Long answer: The GPU API is a relatively thin layer over the
205 * underlying graphics API. While it's possible that we have done something
206 * inefficiently, it's very unlikely especially if you are relatively
207 * inexperienced with GPU rendering. Please see the performance tips above and
208 * make sure you are following them. Additionally, tools like RenderDoc can be
209 * very helpful for diagnosing incorrect behavior and performance issues.
210 *
211 * ## System Requirements
212 *
213 * **Vulkan:** Supported on Windows, Linux, Nintendo Switch, and certain
214 * Android devices. Requires Vulkan 1.0 with the following extensions and
215 * device features:
216 *
217 * - `VK_KHR_swapchain`
218 * - `VK_KHR_maintenance1`
219 * - `independentBlend`
220 * - `imageCubeArray`
221 * - `depthClamp`
222 * - `shaderClipDistance`
223 * - `drawIndirectFirstInstance`
224 *
225 * **D3D12:** Supported on Windows 10 or newer, Xbox One (GDK), and Xbox
226 * Series X|S (GDK). Requires a GPU that supports DirectX 12 Feature Level
227 * 11_1.
228 *
229 * **Metal:** Supported on macOS 10.14+ and iOS/tvOS 13.0+. Hardware
230 * requirements vary by operating system:
231 *
232 * - macOS requires an Apple Silicon or
233 * [Intel Mac2 family](https://developer.apple.com/documentation/metal/mtlfeatureset/mtlfeatureset_macos_gpufamily2_v1?language=objc)
234 * GPU
235 * - iOS/tvOS requires an A9 GPU or newer
236 * - iOS Simulator and tvOS Simulator are unsupported
237 *
238 * ## Uniform Data
239 *
240 * Uniforms are for passing data to shaders. The uniform data will be constant
241 * across all executions of the shader.
242 *
243 * There are 4 available uniform slots per shader stage (where the stages are
244 * vertex, fragment, and compute). Uniform data pushed to a slot on a stage
245 * keeps its value throughout the command buffer until you call the relevant
246 * Push function on that slot again.
247 *
248 * For example, you could write your vertex shaders to read a camera matrix
249 * from uniform binding slot 0, push the camera matrix at the start of the
250 * command buffer, and that data will be used for every subsequent draw call.
251 *
252 * It is valid to push uniform data during a render or compute pass.
253 *
254 * Uniforms are best for pushing small amounts of data. If you are pushing
255 * more than a matrix or two per call you should consider using a storage
256 * buffer instead.
257 *
258 * ## A Note On Cycling
259 *
260 * When using a command buffer, operations do not occur immediately - they
261 * occur some time after the command buffer is submitted.
262 *
263 * When a resource is used in a pending or active command buffer, it is
264 * considered to be "bound". When a resource is no longer used in any pending
265 * or active command buffers, it is considered to be "unbound".
266 *
267 * If data resources are bound, it is unspecified when that data will be
268 * unbound unless you acquire a fence when submitting the command buffer and
269 * wait on it. However, this doesn't mean you need to track resource usage
270 * manually.
271 *
272 * All of the functions and structs that involve writing to a resource have a
273 * "cycle" bool. SDL_GPUTransferBuffer, SDL_GPUBuffer, and SDL_GPUTexture all
274 * effectively function as ring buffers on internal resources. When cycle is
275 * true, if the resource is bound, the cycle rotates to the next unbound
276 * internal resource, or if none are available, a new one is created. This
277 * means you don't have to worry about complex state tracking and
278 * synchronization as long as cycling is correctly employed.
279 *
280 * For example: you can call SDL_MapGPUTransferBuffer(), write texture data,
281 * SDL_UnmapGPUTransferBuffer(), and then SDL_UploadToGPUTexture(). The next
282 * time you write texture data to the transfer buffer, if you set the cycle
283 * param to true, you don't have to worry about overwriting any data that is
284 * not yet uploaded.
285 *
286 * Another example: If you are using a texture in a render pass every frame,
287 * this can cause a data dependency between frames. If you set cycle to true
288 * in the SDL_GPUColorTargetInfo struct, you can prevent this data dependency.
289 *
290 * Cycling will never undefine already bound data. When cycling, all data in
291 * the resource is considered to be undefined for subsequent commands until
292 * that data is written again. You must take care not to read undefined data.
293 *
294 * Note that when cycling a texture, the entire texture will be cycled, even
295 * if only part of the texture is used in the call, so you must consider the
296 * entire texture to contain undefined data after cycling.
297 *
298 * You must also take care not to overwrite a section of data that has been
299 * referenced in a command without cycling first. It is OK to overwrite
300 * unreferenced data in a bound resource without cycling, but overwriting a
301 * section of data that has already been referenced will produce unexpected
302 * results.

2354 * Creates a shader to be used when creating a graphics pipeline.
2355 *
2356 * Shader resource bindings must be authored to follow a particular order
2357 * depending on the shader format.
2358 *
2359 * For SPIR-V shaders, use the following resource sets:
2360 *
2361 * For vertex shaders:
2362 *
2363 * - 0: Sampled textures, followed by storage textures, followed by storage
2364 * buffers
2365 * - 1: Uniform buffers
2366 *
2367 * For fragment shaders:
2368 *
2369 * - 2: Sampled textures, followed by storage textures, followed by storage
2370 * buffers
2371 * - 3: Uniform buffers
2372 *
2373 * For DXBC and DXIL shaders, use the following register order:
2374 *
2375 * For vertex shaders:
2376 *
2377 * - (t[n], space0): Sampled textures, followed by storage textures, followed
2378 * by storage buffers
2379 * - (s[n], space0): Samplers with indices corresponding to the sampled
2380 * textures
2381 * - (b[n], space1): Uniform buffers
2382 *
2383 * For pixel shaders:
2384 *
2385 * - (t[n], space2): Sampled textures, followed by storage textures, followed
2386 * by storage buffers
2387 * - (s[n], space2): Samplers with indices corresponding to the sampled
2388 * textures
2389 * - (b[n], space3): Uniform buffers
2390 *
2391 * For MSL/metallib, use the following order:
2392 *
2393 * - [[texture]]: Sampled textures, followed by storage textures
2394 * - [[sampler]]: Samplers with indices corresponding to the sampled textures
2395 * - [[buffer]]: Uniform buffers, followed by storage buffers. Vertex buffer 0
2396 * is bound at [[buffer(14)]], vertex buffer 1 at [[buffer(15)]], and so on.
2397 * Rather than manually authoring vertex buffer indices, use the
2398 * [[stage_in]] attribute which will automatically use the vertex input
2399 * information from the SDL_GPUGraphicsPipeline.
2400 *
2401 * Shader semantics other than system-value semantics do not matter in D3D12
2402 * and for ease of use the SDL implementation assumes that non system-value
2403 * semantics will all be TEXCOORD. If you are using HLSL as the shader source
2404 * language, your vertex semantics should start at TEXCOORD0 and increment
2405 * like so: TEXCOORD1, TEXCOORD2, etc. If you wish to change the semantic
2406 * prefix to something other than TEXCOORD you can use
