Hi,
I just want to know which is the right and active mailing list for
contributing and discussing about rt-linux and preempt-rt related

Thanks,

Seems like I have fixed the issue myself.

Hi,
I am using Kernel: 4.9.217 for one of the ARM32 boards for Qualcomm SOC.
https://github.com/android-linux-stable/msm-4.9
But I think this is a general bug applicable to :Kernel 4.9 under
fs/sysfs/file.c
So, I wanted to quickly check here if others are familiar with this
issue and if it is fix

Hi All,
This is regarding the KASLR feature support on ARM for the kernel
version 4.9 and 4.14.
Is KASLR supported on ARM-32 Linux 4.9 and above ?
Is it dependent on CONFIG_RANDOMIZE_BASE or
/proc/sys/kernel/randomize_va_space ?
Is there any relation between these two?
Is the changing kernel symb

Hi All,
I am looking for ways to wakeup any devices (from sleep) using any
arbitrary gpio wakeup method in a generic way (either from user space
or kernel space) that should work on any kernel version (starting from
4.14 onwards).
What are the options available right now ?
I wanted to experiment

Hi,
This is an interesting topic for me so I would like to join the conversation.
I will be glad if I can be of any help here either in testing PSI, or
verifying some scenarios and observation.
I have some experience working with low memory embedded devices, like
RAM as low as 128MB, 256MB

Hi All,
I was just wondering if this is possible in the Linux world.
My requirement is:
For some reason, I want to halt/pause the execution (for some
specified time) of a running process/thread (at some location),
without modified the source, may be by firing some events/signals from
an another ext
Hi,
I have a Mac Book Pro with macOS High Sierra 10.13.x installed (with
Mac OS Extended (Journaled, Encrypted)).
I also have the Xcode installed so I can compile a C program using gcc.
Now, I wanted to build linux kernel code (cross compile for arm or
risc-v) on Mac OS.
I know this is possible,

Hi All,
I want to build Linux Kernel 4.20 for arm64 and use it on qemu-arm64.
I see that there is a defconfig available in arch/arm64/configs/defconfig
But I am not sure whether it will work for qemu-arm64, and by default
which machine type is supported.
I already have working setup for qemu-arm
Hello Sai,
Thanks so much for your help.

Hi All,
Currently, I am trying to debug a boot up crash on some qualcomm
snapdragon arm64 board with kernel 4.9.
I could find the cause of the failure, but I am unable to locate from
which subsystem/drivers this is getting triggered.
If you have any ideas or suggestions to locate the issue, please
