Having been reading through Understanding the Linu开发者_如何学Gox kernel (Bovet & Cesati), the chapter on Kernel Synchronisation states that the spin lock acquisition code boils down to:
I\'m reading about different approaches for scaling request handling capabilities on a single machine being taken by node.js, ruby, jetty and company.
Interrupt handlers occur asynchronously and hence cannot be called by other functions. Then, why do interrupt handle开发者_开发百科rs in the linux kernel return a value ? How are the input arguments p
Why can\'t a context switch happen when an interrupt handler is executing ? More specifically, in the linux kernel, interrupt handlers run in the context of the process that was interrupted. Why is it

I\'d like to get the amount of \"free memory\" per NUMA node. When dealing with a whole machine, one usually parses /proc/meminfo like free does (the number wanted is MemFree + Buffers + Cached).
I know user-mode ss/esp should be saved into the kernel-mode stack for later restore. The question is that to locate kernel-mode stack, ss/esp have to be loaded with the corresponding kernel-mode val
