enterprises, IT loses 5 hours of productivity. In the data center and telecom fields, technical staff will also create additional risks when they accidentally unplug some plug that should not be pulled. Assume that a VoIP switch or a key server is accidentally disconnected. As I have reported many times in recent news, what if a device with critical information gets disconnected? How does the network administrator know who is on the network? How are these operations recorded? The biggest benefi

file store. Because the resilient hashing algorithm is used, Glusterfs does not require a dedicated Meta-data server to hold the metadata, thus avoiding the entire cluster being unavailable due to a meta-data server outage. It is precisely because the metadata server does not need, so glusterfs in multiple mount points at the same time to read and write data, its overall performance is very prominent.

For example, the PC's BIOS Providesan ISR for the timer interrupt that maintains the time of the. If you are patchinto the timer interrupt, you'll need to call the PC BIOS ' timer ISR sot

of the CPU. However, the CPU may be executing a command, so the CPU does not respond immediately. When the CPU is busy executing a certain command, there may be other IRQ lines sending interruptions. Please, these requests will accept the selection of IMR. If the request is not blocked, these requests will also be put in IRR, that is, the corresponding bit representing their IRQ in IRR will be set to 1. The figure consists of two 8259a cascade units, which can respond to 15 interrupt sources.

interrupt function is also a function, as long as the system is necessary, you can do something seemingly unreasonable, the shot will be shot, like Goto statement.

Previously we mentioned that the IRQL concept exists in the NT kernel. The level thread scheduling at APC and above is stopped, and only one thread may be running on each CPU. Based on this principle, we can easily see that the spin lock in a single-core system does not need to actually spin. It only needs to increase IRQL to a level without thread switching, this is what the NT kernel does. Each time the spin lock is obtained, the kernel will increase the current IRQL to dispatch_level (or ab

http://blog.csdn.net/chychc/article/details/8313458Ecos Interrupt Model (1) ISR and DSREnglish full name Interrupt Service RoutineInterrupt handling is an important part of the real-time operating system. It is important to deal with interrupt sources in a timely manner, but some actions that must be considered atomic operations (which cannot be interrupted) have a very serious effect on timeliness. Because these actions are performed, disable interru

object already contains these functions. 3. In SWI and tsk, you can disable and enable/hwi_restore of interrupt functions by calling hwi_disable () and Hwi_enable () Hwi (). These functions control global interrupts by manipulating the INTM bit. The hwi_enable () function is to enable global interrupts, and the Hwi_restore () function loads the value before the call to Hwi_disable (). 4. When the HWI is produced, it needs to be protected from the possible changes that it uses before executing i
