<pre>So there is a vulkan wrapper called vulkano (written in rust), and one test
case in particular fails on anv.
The code snippet allocates more memory than reported by vkMemoryHeap.size, but
in multiple allocations. I would expect this to fail with
VK_ERROR_OUT_OF_DEVICE_MEMORY, but it doesn't.
I currently only have a rust code snippet, but from the code it should be
obvious what's happening under the hood:
#[test]
#[ignore] // TODO: test fails for now on Mesa+Intel
fn oom_multi() {
let (device, _) = gfx_dev_and_queue!();
let mem_ty = device
.physical_device()
.memory_types()
.filter(|m| !m.is_lazily_allocated())
.next()
.unwrap();
let heap_size = mem_ty.heap().size();
let mut allocs = Vec::new();
for _ in 0 .. 4 {
match DeviceMemory::alloc(device.clone(), mem_ty, heap_size / 3) {
Err(DeviceMemoryAllocError::OomError(OomError::OutOfDeviceMemory)) => return,
// test succeeded
Ok(a) => allocs.push(a),
_ => (),
}
}
panic!()
}</pre>
