The Halt And Catch Fire project is a collection Vulkan programs designed to crash or hang the GPU.
These programs are used to tools such as Graphics Flight Recorder to ensure they can effectively detect known classes of defects. Do to the nature of these programs their specific behaviour may differ depending on the specific GPU, driver or OS. Not all programs will crash
This is not an officially supported Google product.
Run cmake:
> cmake -Bbuild -DCMAKE_GENERATOR_PLATFORM=x64 -H.
Open the solution: build\halt_and_catch_fire.sln
Programs should be run from the build directory, as shaders (*.spv) are loaded from the workind directory.
$ cmake -Bbuild -H.
$ cd build
$ make
Attempts to crash by performing a DMA copy using unmapped memory (a use-after-free bug).
Attempts to crash by dispatching a compute shader that writes to unmapped memory (a use-after-free bug).
Hangs the GPU by running a compute shader with a long running time (a not-quite inifinite loop).
Hangs the GPU by running a compute shader with a long running time on multiple queues (a not-quite inifinite loop).
Causes a hang by submitting work that waits on an un-set event.
Causes a hang by submitting with a binary wait semaphore that's never signaled.
Causes a hang by submitting with a binary wait semaphore that's never signaled.
Copy the requires shader and execuatble to the same folder.

A few command line options are available:
Choose which queue to execute on (for samples that use a single queue):
`--queue [graphics/compute/transfer]
Not all queue types will be available on all devices.
Execute work from a secondary command buffer, if appropriate:
`--secondary
Add debug names and labels:
`--debug_utils
