13 1165 MHzSUNW,UltraSPARC-T2+ no-intr no-intr = no interruptible.
在linux里 process常见的状态 :
running
interruptible
non-interruptible
...
可以看下面这个,需要对linux内核有适当的了解
这个状态下的进程 不能被普通干预,除非主动地放弃资源。。

An on-line processor processes LWPs (lightweight processes) and can be interrupted by I/O devices in the system.
An off-line processor does not process any LWPs. Usually, an off-line processor is not interruptible by I/O devices in the system.
A no-intr processor processes LWPs but is not interruptible by I/O devices.
A spare processor does not process any LWPs.
A faulted processor is identified by the kernel, which monitors the behavior of processors over time.
The psradm utility changes the operational status of processors. The legal states for the processor are on-line, off-line, spare, faulted, and no-intr.

A no-intr processor processes LWPs but is not interruptible by I/O devices. 能解释下吗,不是很理解。
