Context cost

Agfx Presentation And Swapchain loads about 2k tokens when it runs. Until then it costs about 189 tokens; SKILL.md has 612 words of instructions outside code blocks.

AGFX Presentation & Swap Chain

Overview

agfxSwapChain is AGFX's cross-platform presentation object: on macOS it wraps a CAMetalLayer*, on Windows an HWND, on Linux a pointer to an agfxLinuxWindowHandle (a {display, window} pair whose interpretation — Xlib, XCB, or Wayland — is fixed by the agfxDeviceCreateInfo::displayServerProtocol the device was created with). The contract is deliberately simple — acquire a back buffer texture, render into it via a render pass, barrier it back to AGFX_RESOURCE_STATE_PRESENT, submit, then present. AGFX hides the per-backend present sequences (waitForDrawable/signalDrawable on Metal 4, IDXGISwapChain::Present on D3D12, the binary acquire/present semaphore bookkeeping on Vulkan) behind agfxSwapChainAcquireNextTexture/agfxSwapChainPresent.

Anything that changes the swap chain's underlying resources — resize, or an HDR toggle — requires the GPU to be fully idle first (see agfx-synchronization for drainGPU). AGFX does not do this drain internally; the caller must drain before resizing or recreating.

Ownership

Owns:

agfxSwapChainCreateInfo / agfxSwapChainCreate / agfxSwapChainDestroy
agfxSwapChainResize
agfxSwapChainGetFormat
agfxSwapChainAcquireNextTexture / agfxSwapChainPresent
HDR (isHDR) and vsync (vsync) swap chain configuration
The native handle contract (CAMetalLayer* on macOS, HWND on Windows, agfxLinuxWindowHandle* on Linux) and the Linux-only agfxDeviceCreateInfo::displayServerProtocol field it depends on
AGFX_RESOURCE_STATE_PRESENT as the required pre/post state for the acquired texture

Doesn't own:

Building the render pass that renders into the acquired back buffer texture → agfx-render-targets-and-passes
Draining the GPU / fence semantics that must precede resize or swap chain recreation → agfx-synchronization
Window creation, SDL/AppKit event handling, mouse/keyboard input — engine-level, not part of AGFX

References

Read agfx/agfx.h's // Swap chain section for authoritative struct/enum definitions. agfx_demo/agfx_demo_main.cpp is the full reference implementation: swap chain creation from an SDL window, per-frame acquire/present, resize handling, and HDR toggle.

Design Patterns

Creating the swap chain

cpp

agfxSwapChainCreateInfo swapChainCreateInfo = {};
swapChainCreateInfo.queue = graphicsQueue;      // must be a graphics queue
swapChainCreateInfo.imageCount = 2;             // double buffering; 3 for triple buffering
swapChainCreateInfo.width = drawableWidth;
swapChainCreateInfo.height = drawableHeight;
swapChainCreateInfo.isHDR = false;
swapChainCreateInfo.vsync = true;
#if GAME_MAC
swapChainCreateInfo.handle = metalLayer;        // CAMetalLayer* from SDL_Metal_GetLayer or similar
#elif GAME_LINUX
agfxLinuxWindowHandle linuxHandle = {};         // interpreted per the device's displayServerProtocol
linuxHandle.display = x11DisplayOrWlDisplay;    // Display* / xcb_connection_t* / wl_display*
linuxHandle.window  = x11WindowOrWlSurface;     // Window / xcb_window_t / wl_surface* as uint64_t
swapChainCreateInfo.handle = &linuxHandle;      // read during the create call
#else
swapChainCreateInfo.handle = hwnd;
#endif
agfxSwapChain* swapChain = agfxSwapChainCreate(device, &swapChainCreateInfo);

On Linux the device must have been created with the matching agfxDeviceCreateInfo::displayServerProtocol (AGFX_DISPLAY_SERVER_PROTOCOL_X11/XCB/WAYLAND) — the Vulkan backend enables the corresponding surface extension at instance creation, so this is decided before the swap chain exists; a mismatch fails at agfxSwapChainCreate with a "was the device created with the right displayServerProtocol?" log. With SDL, pick it from SDL_GetCurrentVideoDriver() — see agfx_demo_main.cpp. Note agfx::ez differs here: raw agfxSwapChainCreate consumes the handle struct during the call, but agfx::ez::Context stores the pointer (to recreate the swap chain on an HDR toggle), so there it must outlive the Context.

Query the back buffer's actual pixel format with agfxSwapChainGetFormat(swapChain) rather than assuming a fixed format — it changes when isHDR changes, and any render target/pipeline built against the back buffer must use this queried format (AGFX_TEXTURE_FORMAT_UNKNOWN in the render target's format field lets it inherit automatically; see agfx-render-targets-and-passes).

Per-frame acquire → render → present

cpp

agfxTexture* backBuffer = agfxSwapChainAcquireNextTexture(swapChain);
// backBuffer starts in AGFX_RESOURCE_STATE_PRESENT
agfxCommandBufferTextureBarrier(cmd, backBuffer, AGFX_RESOURCE_STATE_PRESENT, AGFX_RESOURCE_STATE_RENDER_TARGET, 0, 0, /*agglomerate=*/false);

// ... wrap backBuffer in an agfxRenderTarget, run a render pass, draw ...

agfxCommandBufferTextureBarrier(cmd, backBuffer, AGFX_RESOURCE_STATE_RENDER_TARGET, AGFX_RESOURCE_STATE_PRESENT, 0, 0, /*agglomerate=*/false);
agfxCommandBufferEnd(cmd);
agfxCommandQueueSubmit(queue, &cmd, 1);
agfxSwapChainPresent(swapChain);

Pass agglomerate = false specifically for these PRESENT↔RENDER_TARGET transitions around acquire/present (see agfx-synchronization for why: presentable drawables need no explicit hazard tracking on Metal, but D3D12 and Vulkan still need the transition emitted unconditionally — on Vulkan it is a real image layout transition to/from PRESENT_SRC_KHR, and the backend internally treats PRESENT-as-old-state as UNDEFINED since a freshly acquired image's contents are discardable). On Vulkan, agfxSwapChainAcquireNextTexture can also return nullptr when the surface is out of date (e.g. mid-resize, logged as a warning) — skip the frame and resize rather than dereferencing the result. agfxSwapChainPresent must be called only after the command buffer that renders to and barriers the back buffer has already been submitted via agfxCommandQueueSubmit — calling it before submit is a synchronization bug.

Resize handling

Resizing is destructive to in-flight GPU work referencing swap chain resources, so always drain first:

cpp

// On a window resize event:
drainGPU(); // see agfx-synchronization — signal + wait until the frame fence catches up
agfxSwapChainResize(device, swapChain, newWidth, newHeight);
renderer.Resize(device, newWidth, newHeight); // resize any render targets sized to match the window

HDR toggle

AGFX has no in-place HDR reconfiguration API — toggling HDR means destroying and recreating the swap chain, then recreating anything downstream whose pipeline format depended on the old back buffer format:

cpp

drainGPU();
agfxSwapChainDestroy(device, swapChain);
swapChainCreateInfo.isHDR = wantHDR;
swapChain = agfxSwapChainCreate(device, &swapChainCreateInfo);
renderer.RecreateTonemapPipeline(device, agfxSwapChainGetFormat(swapChain));
imguiBackend.RecreatePipeline(device, agfxSwapChainGetFormat(swapChain));

Skipping the pipeline recreation step is the most common HDR-toggle bug: the render pass will still bind fine, but color-attachment format mismatch between the pipeline and the actual back buffer produces validation errors on D3D12 and garbage/black output on Metal.
