From: Nianfu Bai <nianfu.bai@unisoc.com>

Tick broadcast installed by insmod cannot switch to oneshot mode correctly
caused by linux timer framework, need to build in kernel image. SPRD_TIMER
has been selected by SPRD arch, we have to enable SPRD arch when we build
sprd timer in kernel image, this action conflicts with general kernel image,
so we need to remove the dependency between sprd timer and SPRD arch.

This wording is a bit rough to parse.

All you really want to do is take away the fact that ARCH_SPRD is
required here to turn this off, right?

No need for "if COMPILE_TEST" on this line.

Just drop the ARCH_SPRD portion here and maybe make it depend on ARM64
instead like:
	depends on (ARM64 || COMPILE_TEST)

and drop the EXPERT check above?

What is the goal of what you want to do here?  Just allow this to be
enabled on what type of systems?

thanks,

What timer is compiled as a module? Why the timer framework does not
allow to switch to it ?

Can you rephrase the changelog, I'm not getting the point.

Thanks for the pointer I understand the bug.

However the description does not refer to this fix. It tells the timer
is a module and then tells it depends on the sprd arch.

What are the connection between all these points?

On the other side, the email format is not text, replies are not
correctly put inline, it is hard to follow the discussion.

Please, take the time to read the documentation about submitting patches
[1] and then provide a clear Changelog, no need to refer the timer is
loaded after because it is a module, the Kconfig says the opposite.

Thanks

description, sprd timer can not build as a module, we have to build
sprd timer in kernel image, but the sprd timer is depend on sprd arch,
we do not want to enable sprd arch config when build sprd timer in
kernel image, so we need to remove the dependency between sprd timer
and sprd arch.

From: Nianfu Bai <nianfu.bai@unisoc.com>

Tick broadcast installed by insmod cannot switch to oneshot mode correctly
caused by linux timer framework, need to build in kernel image. SPRD_TIMER
has been selected by SPRD arch, we have to enable SPRD arch when we build
sprd timer in kernel image, this action conflicts with general kernel image,
so we need to remove the dependency between sprd timer and SPRD arch.
