例如，如果AMD64系统有2 GiB内存，那么所有内存都属于ZONE_DMA32范围，而ZONE_NORMAL则为空。
1. node_zones:每个Node划分为不同的zone,分别为ZONE_DMA,ZONE_NORMAL,ZONE_HIGHMEM 2. node_zonelists:这个是备用节点及其内存域的列表,当当前节点的内存不够分配时,会选取访问代价最低的内存进行分配。分配内存操作时的区域顺序,当调用free_area_init_core()时,由mm/page_alloc.c文件中的build_zonelists()函数...

unload queue: |--Unload 0--|* |--Unload 1--|* |--Unload 2--|* The overlapping relies on hardware in the GPU that allows DMA transfers to be setup for host to device and device to host copies. Some GPUs have hardware to allow two copies to proceed at the same time allowing full...

SA2 has studied the UE mobility customisation per UE under the Key Issue 9 during the Rel-16 eNA study (TR23.791 v2.0.0) agreeing solutions for UE registration area customisation based on analysis on historical UE location. However, the SA2 has also studied and agreed some solutions for opt...
