* Add RHI Device Caching and Test Prefix Exclusion (#8448)Gangzheng Tong2025-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | # Add RHI Device Caching and Test Prefix Exclusion ## Summary This PR introduces two key improvements to the Slang test infrastructure: 1. **RHI Device Caching**: Implements device caching to significantly speed up test execution by reusing graphics devices across tests, **RHI Device Caching reduces slang-test execution time from ~15 minutes to ~5 minutes in Windows release builds** 2. **Test Prefix Exclusion**: Adds `-exclude-prefix` option to skip tests matching specified path prefixes ## Changes ### RHI Device Caching - **New `DeviceCache` class** (`slang-test-device-cache.h/cpp`): Thread-safe device cache with LRU eviction (max 10 devices) - **Cache control option**: `-cache-rhi-device` flag in both `slang-test` and `render-test` - Default: **enabled** in slang-test, **disabled** in render-test when run standalone - Automatically skips caching for CUDA devices (due to driver issues) - **Performance benefit**: Eliminates expensive device creation/destruction cycles, especially beneficial for Vulkan on Tegra platforms ### Test Prefix Exclusion - **New `-exclude-prefix <prefix>` option** in slang-test - Allows excluding entire test directories or patterns from execution - Complements existing `-category` and individual test filtering options ### Usage Examples ```bash # Enable device caching (default) slang-test # Disable device caching slang-test -cache-rhi-device false # Exclude tests from specific directories slang-test -exclude-prefix tests/problematic/ slang-test -exclude-prefix tests/slow/ -exclude-prefix tests/experimental/ ``` This change should significantly improve test execution performance, particularly in CI environments with frequent device operations. This is needed for running the GPU test in aarch64, where repeated device creation/destroy is causing driver issues.

* render-test: Change D3D12 default to sm_6_5 (#8320)James Helferty (NVIDIA)2025-09-02
| | | | | | | | | Changes default for render-test to sm_6_5. Since sm_6_5 is the new default, remove the -use-dxil option, add -use-dxcb option Remove -use-dxil option from all test cases. Add -use-dxcb to two tests that needed it. Fixes #7611
* Handle debug-layer messages in a separate channel (#7988)Jay Kwak2025-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Handle debug-layer messages in a separate channel The Problem (Issue #7343) The issue was that Vulkan Validation Layer error messages were being mixed into regular test output, causing potential false positives or negatives. When using -enable-debug-layers true, validation messages would appear in the same output stream as test results, potentially matching //CHECK: patterns incorrectly. Example Problem: - Test expects: //CHECK: 1 - Validation layer prints: VALIDATION ERROR: 1 invalid buffer binding - Test incorrectly matches the "1" in the error message instead of the actual output Slang Test Communication Architecture Execution Modes Slang has 3 different execution modes controlled by SpawnType: enum class SpawnType { UseSharedLibrary, // In-process execution UseTestServer, // Out-of-process via persistent server UseFullyIsolatedTestServer, // Out-of-process via isolated server UseExe // Direct executable spawn } 1. In-Process Mode (UseSharedLibrary) ┌─────────────────────────────────────────┐ │ slang-test │ │ ┌─────────────┐ ┌─────────────────┐ │ │ │render-test │ │gfx-unit-test │ │ │ │unit-test │ │slangc library │ │ │ └─────────────┘ └─────────────────┘ │ │ │ │ │ │ └───► StdWriters ◄──┘ │ │ (shared) │ └─────────────────────────────────────────┘ - Communication: Direct function calls, shared memory - Debug callbacks: Single callback instance in StdWriters - Used when: Default mode for most tests 2.

Direct Executable Mode (UseExe) ┌──────────────────┐ pipes ┌──────────────────┐ │ slang-test │◄───────────────┤ slangc.exe │ │ │ │ other tools │ └──────────────────┘ └──────────────────┘ - Communication: Standard process pipes (stdout/stderr) - Debug callbacks: None (external executables) - Used when: Testing external tools Communication Mechanisms Deep Dive JSON-RPC Protocol Over Pipes The test-server.exe communicates with slang-test using JSON-RPC over stdin/stdout pipes: // Parent process (slang-test) creates child with pipes Process* testServerProcess = /* spawn test-server.exe */; // JSONRPCConnection wraps the pipe communication JSONRPCConnection connection; connection.initWithStdStreams(); // Uses stdin/stdout pipes // Send RPC call TestServerProtocol::ExecutionResult result; connection.sendCall("executeTool", &args, &result); Key Point: The pipes carry structured JSON messages, not raw stdout/stderr. This is what enables clean separation of different data channels. Protocol Structure Your changes extend the ExecutionResult protocol: struct ExecutionResult { String stdOut; // Regular program output String stdError; // Error messages String debugLayer; // NEW: Debug/validation messages int32_t result; int32_t returnCode; }; Your Debug Layer Solution The Challenge Memory pointers cannot cross process boundaries. A debugCallback pointer in the parent process is meaningless in the child process. The Solution: String-Based Serialization You solved this by using string capture and serialization: 1. Debug Callback Interface (slang-std-writers.h) class IDebugCallback { virtual void handleMessage( DebugMessageType type, DebugMessageSource source, const char* message) = 0; }; 2. String-Capturing Implementation (slang-support.h) class CoreDebugCallback : public Slang::IDebugCallback { StringBuilder m_buf; // Captures messages as strings void handleMessage(DebugMessageType type, DebugMessageSource source, const char* message) { if (type == DebugMessageType::Error) { m_buf << message << '\n'; // Serialize to string } } String getString() { return m_buf.toString(); } // Extract accumulated messages }; 3. Bridge Between RHI and Core (slang-support.h) class CoreToRHIDebugBridge : public rhi::IDebugCallback { Slang::IDebugCallback* m_coreCallback; void handleMessage(rhi::DebugMessageType type, rhi::DebugMessageSource source, const char* message) { // Convert RHI types to core types and forward m_coreCallback->handleMessage(convertType(type), convertSource(source), message); } }; Data Flow: Debug Messages End-to-End In-Process Mode Flow GPU Driver → RHI Debug Callback → Core Debug Callback → String Buffer → Test Output Out-of-Process Mode Flow Child Process: GPU Driver → RHI Debug Callback → Core Debug Callback → String Buffer ↓ Parent Process: JSON-RPC Serialization Test Output ← String Processing ← ExecutionResult.debugLayer ←┘ Step-by-Step Example 1. Test Execution Starts // In test-server process CoreDebugCallback debugCallback; CoreToRHIDebugBridge bridge; bridge.setCoreCallback(&debugCallback); // Set up graphics device with debug layers deviceDesc.debugCallback = &bridge; 2. Graphics API Call Triggers Validation Error // Inside Vulkan driver (external code) // Validation layer detects error and calls our callback bridge.handleMessage(RHI_ERROR, RHI_LAYER, "Invalid buffer binding"); 3. Message Capture // In CoreDebugCallback::handleMessage m_buf << "Invalid buffer binding\n"; // Stored in string buffer 4. Test Completion & Serialization // Back in test-server TestServerProtocol::ExecutionResult result; result.debugLayer = debugCallback.getString(); // "Invalid buffer binding\n" result.stdOut = "1"; // Regular test output // Send via JSON-RPC connection.sendResult(&result); 5. Parent Process Receives & Separates Output // In slang-test process String output = buildTestOutput(result); // Results in clean separation: // standard output = { // 1 // } // debug layer = { // Invalid buffer binding // } Why This Solution Works 1. Process Isolation: Each process has its own callback objects, no shared pointers 2. String Serialization: Debug messages converted to strings that can cross process boundaries 3. Protocol Extension: Uses existing JSON-RPC infrastructure, just adds new field 4. Clean Separation: Debug messages never mix with stdout/stderr 5. Backward Compatibility: Existing tests unaffected, debug layer field optional Key Benefits - Eliminates False Positives: Debug messages can't interfere with //CHECK: patterns - Better Debugging: Debug messages clearly separated and labeled - Robust Architecture: Works across all execution modes - Minimal Changes: Leverages existing communication infrastructure This elegant solution transforms a fundamental cross-process communication challenge into a simple string serialization problem, using the existing test server architecture to cleanly separate validation layer messages from test results. * Cover the missing slang-test execution path * format code (#82) Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> --------- Co-authored-by: slangbot <ellieh+slangbot@nvidia.com> Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

* Add a new slang-test option `-enable-debug-layers` (#7300)Jay Kwak2025-06-02
| | | | | | | | | | | | | | | | | | | | | | * Add a new slang-test option `-enable-debug-layers` A variable `disableDebugLayer` is renamed to `enableDebugLayers`, and a corresponding command-line argument is added, `-enable-debug-layers`. The previous option `-disable-debug-layer` is still available, but it prints a deprecation warning message. The reason why it is added is to make the option available to both Debug and Release. On Debug build, it will be enabled by default, and it will be disabled on Release build. We should be able to not only disable it, but also enable it on Release build. Ideally this option should be enabled all the time, but currently there are too many VUID error messages printed and we are enabling only for Debug build for now. Note that the CI/CD will run with the option disabled until we resolve all of VUID errors.

* Enable D3D12 experimental feature to use coopvec (#6290)Jay Kwak2025-02-05
| | | | | | This commit enables "D3D12-experimenta-feature" in render-test. This is required to use CoopVec feature with dxcompiler.dll. But it is enabled only when "-dx12-experimental" is used, because it appears that DX12 becomes unstable when the experimental feature is enabled, which causes bunch of tests randomly failing.
* Update Slang-RHI and enable any debug layers up-front (#6226)Anders Leino2025-01-31
| | | | | | | | | | | | | | | | | | | | * Update Slang-RHI and enable any debug layers up-front As [1] shows, creating a D3D12 device and then enabling debug layers causes future device creation to fail. That means enabling debug layers is a process-wide decision that should be done at startup, and not just before creating an individual device. Previously, Slang-RHI enabled debug layers as part of device creation. The new Slang-RHI revision doesn't do that anymore, but instead allows the user to enable debug layers earlier, with a separate API. This change calls the mentioned API before creating any device. This closes #6172. * Compile fixes needed after updating slang-rhi --------- Co-authored-by: Yong He <yonghe@outlook.com>

* Avoid using the backend validation when using test server (#6094)Jay Kwak2025-01-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | * Avoid using the backend validation when using test server Currently with a debug build, the backend validation such as Vulkan-Validation-Layer or DXC validation is enabled all the time. It means there is a higher chance that we see warning messages while running slang-test with a debug build. However, those warning messages incorrectly treated as the testing result when using test-server. This is mainly because of the fact that the Slang implemention for the RPC commucation expects only one time output result. As soon as any warning is printed, the testing process is incorrectly considered as completed even though it might be still in the middle of initializing the device. This commit disables the backend validation when using the test-server. * format code (#31) Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> --------- Co-authored-by: slangbot <ellieh+slangbot@nvidia.com> Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He <yonghe@outlook.com>

Added tests to be sure this works as intended with user API and with slangc command line * Change capability atom definitions and how Slang manages them to fix errors 1. most `glsl_spirv` version atoms have been removed from `.capdef`, instead we will translate `spirv` version atoms into `glsl_spirv` since there is no point in writing the same code twice in `.capdef` files to define `spirv` versions. 2. add spirv version, and hlsl sm version (and equivlent) capability dependencies 3. removed some stage requirments which were set on objects, keep the wrapper capabilities. I am keeping the wrapper capabilities since I am unaware on if there are stage limitations (spec says code in practice does not work). * check internal version instead of version profile (_spirv_1_5 vs. spirv_1_5) * remove unused OpCapability. adjust SPIRV version'ing again for glsl_spirv * apply workaround for glslang bug with rayquery usage * ensure capabilities targetted by a profile and added together by a user are valid * remove additions to `spirv_1_*` wrapper * spirv_* -> glsl_spirv fix * fix bug where incompatable profiles would cause invalid target caps * try to avoid joining invalid capabilities * fix the warning/error & printing * run through tests to fix capability system and test mistakes many mistakes were mesh shaders doing `-profile glsl_450+spirv_1_4`.
