As reported in #8079 ...
Vulkan's API permits any arbitrary alignment and padding on every Buffer allocation, which means that the memory requirements have to be queried for every block and region prior to binding device memory.
Previously, we were only querying the requirements on the creation of the block, and assuming that all regions (which used the same device memory pool, and physical allocation) would match. This was an invalid assumption, and was only partially fixed in #8087.
This PR introduces a new
conformcallback API which allows block and region allocations to query the memory requirements before the block allocator actually binds memory and creates/splits regions.I also added more test cases in
/test/runtime/runtime_internal_block_allocatorto verify the size, alignment and offsets are constrained as expected.Fixes #8079
