When writing device drivers, memory buffers used for DMA often need to be aligned to the cache line size. If a buffer crosses a cache line boundary and the CPU modifies adjacent memory while the device performs DMA, data corruption can occur.
The application binaries are loaded into an isolated user-space memory segment. The runtime engine intercepts the x86 instruction stream before it reaches the host CPU. 2. Dynamic Binary Translation (DBT) cls magic x86
Elias hovered his finger over the 'Y'. He wondered, if he cleared the screen of the universe, what would he find written underneath? When writing device drivers, memory buffers used for
