it is the responsibility of the operating system to map the virtual address provided by the process to the physical address where that memory is stored. The page table is where the operating system stores its mappings of virtual addresses to physical addresses. 这么说,是操作系统负责把虚拟内存...

VSM的PhysicalShadowMap也会被切割成多个Page,这里Page就是Physical Page,大小和VirtualPage一样。之后virtual address到physical address的映射就是以Page为单位。 VSM的整体绘制流程 在场景渲染刚开始,收集所有运动过的物体,将他们所覆盖的Physical Page标记为失效。(Pass:VirtualSmInvalidateInstancePages) 在BasePass绘制...

逻辑地址(Logical Address):程序中指令所用地址(进程所在地址空间),也称为虚拟地址(Virtual Address,简称VA) 物理地址(Physical Address,简称PA):存放指令或数据的实际内存地址,也称为实地址、主存地址。物理地址(Physical Address,PA):计算机系统的主存被组织为M个连续的字节大小的单元组成的数组。每个字节的地址叫物...
map (id, block, page_number, permission): put a block into id's address space. map maps the physical address block to virtual page page_number with permissions permission. The memory manager allocates an entry in the page map for address space id, mapping the virtual page page_number to...
A method and apparatus for translating a virtual address to a physical address. A virtual address to be translated has a virtual page offset and a virtual page number. The virtual address to be translated addresses a page of memory. The size of this page is unknown. There are L different ...
When you know a valid virtual address, you can pass it to our tool to get actual value from pagemap, including physical frame number. Here is an example: $ #let's find get virtual address of a page$ cat /proc/self/maps00400000-0040b000 r-xp0000000008:021177367/bin/cat ...
