The patch applies to Level Zero. Only allocations < 2MB will be fetched from the pool. Allocations are shared and reused within a given device. Additionally, I added a new debug flag to control the allocator: EnableTimestampPoolAllocator Related-To: NEO-12287 Signed-off-by: Fabian Zwoliński <fabian.zwolinski@intel.com>
