I am trying to get a better understanding of the definition preemptive and cooperative in the context of Go. Wiki states for preemptive multitasking In computing, preemption is the act of temporar...

I am new to Linux and am reading Linux device drivers book by Rubini & Corbet. I am confused at one statement related to spinlocks; the book states If a nonpreemptive uniprocessor system ev...

I am reading Linux Kernel Development recently, and I have a few questions related to disabling preemption. In the "Interrupt Control" section of chapter 7, it says: Moreover, disabling interr...

In Kubernetes we can set the priority of a pod to Guaranteed, Burstable or Best-Effort base on requests and limits. Another method to assign priorities in Kubernetes is to define a priorityClass ob...

I try to understand why the user has to call the taskYIELD_FROM_ISR() method and why it isn't automatically called by the RTOS within the xStreamBufferSendFromISR method. My question refers to the...

I read that Linux kernel is preemptive, which is different from most Unix kernels. So, what does it really mean for a kernal to be preemptive? Some analogies or examples would be better than pure ...

Say I have this: public void foo(){ CompletableFuture.delayedExecutor(1, TimeUnit.MILLISECONDS).execute(() -> { doSomethingA(); }); doSomethingB(); } Is there any guarantee that doSom...

I'm wondering if it's possible to implement preemptive multitasking of native code within a single process in user space on Linux. (That is, externally pause some running native code, save the cont...

Sometimes whenever I write a program in Linux and it crashes due to a bug of some sort, it will become an uninterruptible process and continue running forever until I restart my computer (even if I...

Wikipedia says: In computing, preemption is the act of temporarily interrupting a task being carried out by a computer system, without requiring its cooperation, and with the intention of resuming...

Explained in your own words, what is preemption and what does it mean to a (linux) kernel? What are advantages and disadvantages in having a preemptible kernel?

I need to be able to save the state of a Centos-based Google Compute instance when it first receives a preemption signal. The documentation very clearly indicates that a "ACPI G2 Soft Off" signal i...

To give you full context my discussion begun with an observation that I am running a SMP linux (3.0.1-rt11) on ARM cortex A8 based SoC which is a uniprocessor. I was curious to know if there will b...

I'm struggling to understand one thing about preemption. Citing Wikipedia: In computing, preemption (more correctly pre-emption) is the act of temporarily interrupting a task being carried out ...

I have written a test program to test out SCHED_FIFO. I have learnt that SCHED_FIFO cannot be preempted by SCHED_OTHER threads. But I couldn't explain the results obtained when same program is run ...

I just reading an article which says: Reasons to control the interrupt system generally boil down to needing to provide synchronization. By disabling interrupts, you can guarantee that an interr...

When a process in the kernel space is holding a spin_lock, the process cannot be preempted due to any of the following conditions : When the time-slice of the process gets exhausted When a high ...

Would like to know how the scheduler gets called so that it can switch tasks. As in even if its preemptive scheduling or round robin scheduling - the scheduler should come in to picture to do any k...
