linear address space

基本解釋

A 64-bit application can directly access 4 exabytes of virtual memory, and the Intel Itanium processor provides a contiguous linear address space.
位的應(yīng)用程序可以直接訪問 4EB 的虛擬內(nèi)存，Intel Itanium 處理器提供了連續(xù)的線性地址空間。
Within a driver, the mmap function is implemented through the remap_pfn_range kernel function, which provides a linear mapping of device memory into a user's address space.
在一個驅(qū)動程序中，mmap 函數(shù)通過 remap_pfn_range 內(nèi)核函數(shù)實現(xiàn)，它提供設(shè)備內(nèi)存到用戶地址空間的線性映射。
