1. 这里面的宏都和线性地址的最后1GB有关,其中__VANALLOC_RESERVE为128M,下图说明了第4GB的内存划分 结合这个图我们可以得出MAXMEM为一个略小于896M的值(896M-8K-4M-4M),即略小于低端内存的上限,高端内存的起始地址,这样是为了避免某些情况下产生的OOPS。 走得貌似有点远了,再回到e820_end_of_ram_pfn(),...

VTune probably does counter freezing on the initial overflow, but that has known bugs in several processor families, and it is not always easy to be sure that all the transactions initiated in the runtime library have completed their cache transactions before the counters are unfrozen... ...
