Since only 29 bits are available for mapping physical memory, only 512 MB of physical memory space can be accessed through this segment in 32-bit mode. Some of this space must be reserved for device addressing. It is possible to gain cached access to wider physical addresses by mapping throu...

Disclosed are various examples of providing efficient bit compression for direct mapping of physical memory addresses. In some examples, a hypervisor operating system component generates a mask of used address space bits indicated by memory map entries for a computing device. A longest range of ...
A Physical address is a 48-bit flat address burned into the ROM of the NIC card which is a Layer1 device of the OSI model. This iis divided into 24-bit vendor code and 24-bit serial address. This is unique for each system and cannot be changed. A Logical address is a 32- bit ad...
address physical memory by-passing the operating system's normal memory management. As of Windows 8 and Windows Server 2012 and later, AWE memory is included in the process private bytes(\Process(*)\Private Bytes). Otherwise, tools like Sysinternals RAMMap can be used to identify AWE memory ...
ZONE_HIGHMEM is the part of the physical memory that is not covered by a permanent mapping in the kernel page tables. The memory in this zone is only accessible to the kernel using temporary mappings. This zone is available only on some 32-bit architectures and is enabled with CONFIG_HIGHME...
The parameter has a slightly different meaning for x86 systems (both 32 and 64 bit): "mem=nn[KMG] […] [X86] Work as limiting max address" (source). Due to reserved memory sections, its value on x86 will be higher than the amount of memory to make available to the OS. Example: ...
1. A computer adapted for low rank addressing of main memory, comprising: a memory system comprising memory modules arranged in ranks, where the ranks have a number equal to a non-power-of-two; a processor receiving memory access requests each including a physical address (PA) to the memory...
