hardware, but interacts with the native I/O memory (I/O memories, which are located in the kernel space). So-called I/O memory is a variety of excuses (PCI, USB, Bluetooth, Ethernet port, etc.) connected to the host (PC, mobile phone) hardware (network card, sound card, camera, etc.)The mappings in host memory. For example, a driver running on Ubuntu Linux only needs to access I/O memory in a host running Ubuntu Linux, and then the Linux kernel interacts with the data hardware in I/O memory.The

Sunmicrosystem company.Operating featuresRISC chips typically operate at 400MHZ orders of magnitude. The clock frequency is low, the power consumes less, the temperature rises also is few, the machine is not easy to fail and the aging, improves the system reliability. A single instruction cycle accommodates multiple parallel operations. In the development process of RISC microprocessors. Has produced the ultra-long instruction Word (VLIW) microprocessor, which uses a very long set of instructio

program. Specifically, you can use the user program to configure kernel service program parameters, extract the data provided by the kernel service program, of course, you can also enter the processing data to the kernel service program.Typical applications include: NetFilter (Kernel service Program: firewall) vs iptable (User-level program: Rule Setup program), IPSEC (kernel service Program: VPN protocol section) vs IKE (User-level program: VPN key negotiation processing) And, of course, a lar

Let's look at its definition first.Inlinebool heap_segment_in_range_p (heap_segment* inst) {//it returns a bool type, of course this bool is a custom return (!) ( Inst->flags heap_segment_flags_readonly) | | ((Inst->flags heap_segment_flags_inrange)! = 0));}Of course we have to know a basic definition, and the following variable
