The virt_to_bus() and bus_to_virt() functions have been superseded by the functionality provided by the PCI DMA interface (see Documentation/DMA-API-HOWTO.txt). They continue to be documented below for historical purposes, but new code must not use them. --davidm 00/12/12 ] must not...

The room-temperature storage modulus of 3-4 years Moso bamboo and Dendrocalamus Latiflorus Munro were tested by Q800 dynamic mechanical thermal analysis (DMA). The outer faces of Moso bamboo and Dendrocalamus Latiflorus Munro board as laminated fabricated at different of ages were tested by INSTRON...
Physmeme 是一个驱动映射器,它适用于任何形式的物理内存读写。它是高度模块化的代码,允许逆向工程师轻松集成他们自己的易受攻击的驱动程序。如果您能够读取和写入物理内存,您现在只需编写四个函数即可将未签名的驱动程序映射到内核中。 怎么运行的 Physmeme 的工作方式与更高级别的kdmapper类似。内联挂钩系统调用,然后...

The artwork illustrates the basic principle of the method used to perfom the most essential measurements of this work, dynamic mechanical analysis (DMA). Superimposed on the sample polymer-nanocomposite strip is the corresponding skeletal formula. Also shown are schematics of the featured components, ...
address address to remapDESCRIPTION The returned physical address is the physical (CPU) mapping for the memory address given. It is only valid to use this function on addresses directly mapped or allocated via kmalloc. This function does not give bus mappings for DMA transfers. In almost all co...
