Yes, however the entire d3d12_desc structure is memset away, including the lock. Another solution to this problem would involve using "descriptor headers" that go in between the _desc structures in heap->descriptors.On Thu, Sep 12, 2019 at 5:18 AM Derek Lesho <dlesho@codeweavers.com> wrote:

On Linux, pthread_spinlock_t is just a single int (not sure about the Mac equivalent but probably similar). It's more efficient to declare cur_desc->lock as a pthread_spinlock_t rather than a pointer to one in allocated memory.
