| # Enable Metal Validation without Xcode. |
| |
| To enable validation of all Metal calls without using Xcode, add the following |
| to your rc file. |
| |
| These flags are not documented and have been reverse engineered from observing |
| what Xcode does to enable these validation layers. |
| |
| |
| ``` |
| # Metal Tracing Defaults |
| export DYLD_INSERT_LIBRARIES="/usr/lib/libMTLCapture.dylib:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/GPUToolsPlatform/libMTLToolsDiagnostics.dylib" |
| export METAL_DEBUG_ERROR_MODE=0 |
| export METAL_DEVICE_FORCE_COMMAND_BUFFER_ENHANCED_ERRORS=1 |
| export METAL_DEVICE_WRAPPER_TYPE=5 |
| export METAL_DIAGNOSTICS_ENABLED=1 |
| export METAL_LOAD_INTERPOSER=1 |
| export MTL_FORCE_COMMAND_BUFFER_ENHANCED_ERRORS=1 |
| export DYMTL_TOOLS_DYLIB_PATH="/usr/lib/libMTLCapture.dylib" |
| ``` |
| |
| |
| These flags have been validated to work on macOS Monterey (12.0.1) |
