You can then assign a different IRQ to that network card.
然后你能分配不同的IRQ到那网络备置卡片。
Each device you attach to a computer may need its own IRQ port.
你对一部计算机附加的每个装置可能需要它自己的IRQ端口。
At least one other device that USES that IRQ was already opened.
至少有一个使用该IRQ的其他设备已打开。
IRQ conflicts are common when you're connecting a lot of devices.
当你正在连接许多装置的时候，IRQ冲突是通常的。
It could be an IRQ conflict or a device driver that doesn't work.
这也可能是中断冲突或驱动这行不通。
Typically, when a device driver registers an NIC, it requests and assigns an IRQ.
代表性的，当一个设备驱动注册成一个NIC，它要请求分配一个IRQ。
The IRQ column indicates the number of interrupts that occurred while that process was running.
irq栏指明了在进程进行过程中发生的中断的数目。
This helps the kernel IRQ layer clearly identify which driver is handling that particular interrupt.
这样可以帮助内核的IRQ层清楚地识别出哪个驱动程序正在处理那个特定的中断。
For example, to bind processing of IRQ number 177 to CPUs 4 through 7 (bitmask 11110000), issue.
例如，以下命令将IR q号为177的中断的处理绑定到CPU4到CPU7(位掩码11110000)。
If possible, please change the COM3 and COM4 port IRQ Settings, so that they no longer conflict.
如果可能的话，请更改COM3和COM 4端口的IRQ设置，使它们不再冲突。
Note that to identify the handler, the kernel needs both the IRQ number and the device identifier.
注意，为了标识处理句柄，内核同时须要IR Q号和设备ID。
The IRQ signal is delivered to the local APICs listed in the corresponding Redirection Table entry.
IR Q信号发送给对应重定向表条目中所列的局部APIC。
For example, if you want to assign IRQ 10 to the second Ethernet adapter, run the following command.
举例来说，如果你想要分配IRQ10到第二个以太网络转接器，运行下列的指令。
Show all IRQ Numbers and addresses as seen by the CARDS on the PCI bus instead of as seen by the kernel.
显示所有IR q号和内存地址，就象PCI总线上的卡看到的一样，而不是内核看到的内容。
Each IRQ line is defined by an instance of this structure. Among other fields, it includes a callback function.
每一个IR Q线路都定义了一个这个数据结构的实例。和其它字段一起，还包括一个回调函数。
Registers and releases, respectively, a callback handler for an IRQ line. The registration can be exclusive or Shared.
分别用于注册和释放在IR Q线路上的回调句柄！
If your printer doesn't work after you've connected a second network card, it can help to know the standard IRQ for printers.
如果在你已经连接一个第二个网络卡之后，你的打印机不工作，它能帮助为打印机知道标准的IRQ。
Given the device identified by dev_id, this function removes the handler and disables the IRQ line if no more devices are registered for that IRQ.
id给出了设备唯一标识，如果一个IR Q上已经没有了注册的设备，这个函数就用于删除处理句柄并禁用IRQ总线。
By default, the driver IRQ routine should return IRQ_HANDLED as it is a bug to return IRQ_NONE when the driver has actually handled that interrupt.
缺省情况下，驱动程序IR Q例程应该返回IRQ_HANDLED，当驱动程序正在处理那个中断时却返回了IRQ_NONE，说明存在bug。
This change, introduced by Linus, means that the interrupt handlers tell the generic IRQ layer whether the interrupt is really meant for it or not.
这个由Linus引入的变化意味着中断处理程序告诉通用的IR q层是否真的要中断。
In other words, an FIQ is just a higher priority interrupt request, that is prioritized by disabling IRQ and other FIQ handlers during request servicing.
在换句话说，一个FIQ仅仅是一个更高优先级的中断请求时，由请求服务期间禁用IRQ和其他FIQ处理程序的优先级。
For instance, on one embedded x86 system I used, the CardBus controller was unusable because it needed to have an IRQ programmed into it; a BIOS update fixed this.
例如，在我使用的一个嵌入式的x86系统上，CardBus控制器无法使用了，这是因为它需要一个IRQ进行编程；升级BIOS可以修复这个问题。
