buddy_system_allocator也是rCore这个社区的项目.cd ~/workspace git clone https://github.com/rcore-os/buddy_system_allocator.git 从实用的角度开始看源码为了起一个好头,还是从比较熟悉的部分看代码,思考代码是怎么组织的:buddy_system_allocator是怎么作为一个外部包被引用的? 上一部分我们调用了LockedHeap,...

HSCC is implemented with zsim-nvmain hybrid simulator, it has achieved the following functions: (1) Memory management simulations (such as MemoryNode, Zone, Buddy Allocator etc.); (2) TLB, page table and reversed page table simulations; (3) Implementation of SHMA, a hierarchical hybrid DRAM/...
Memory management simulations (such as MemoryNode, Zone, Buddy allocator etc.): As the pin-based zsim only replays virtual address in the x86 system architecture, and does not support OS simulation, HSCC has added memory management modules into zsim, including memory node, zone and buddy alloca...
