Yes, this the way to do.
Please patch lpae, default and vanilla to be consistent across configs.

I can send patch to opensuse-kernel ml if thats suitable, this way is
described on the wiki
https://en.opensuse.org/openSUSE:Kernel_git#Submitting_your_changes_to_the_kernel_team
What do you think is patch for lpae enough or better add default and
vanilla also?

Thanks.
Could you submit your patch to stable branch for default, lpae and vanilla
flavours, please?
Patches against master branch should follow once git repo fixed.

Perfect!
I submitted an update request to include it:
https://build.opensuse.org/request/show/323645
We still need to update our kernel config to disable exynos IOMMU. But
kernel repo is currently broken for master.
Could send your config patch against stable kernel (4.1), please?

Adding them with force_drivers do the trick.

You do not need to modify your kernel for that.
Remove your /etc/modules-load.d/ file to get back in non-auto loading.
Open the file '/etc/dracut.conf.d/exynos_modules.conf' and add the
following
line:
add_drivers += "cros_ec_devs ptn3460 pwm-samsung"
Then recreate your initrd with:
dracut -f
and reboot.
If it does not help, replace:
add_drivers += "cros_ec_devs ptn3460 pwm-samsung"
by:
force_drivers += "cros_ec_devs ptn3460 pwm-samsung"
Then recreate your initrd with:
dracut -f
and reboot.

I made test on already installed image. Connected with usb network
dongle, cloned kernel-source git, made sequence-patch to 4.1 source,
copied modified lpae kernel config then booted
resulting kernel.
This extra modules i tried to add to /etc/modules-load.d/ and system
start fine this way without manual modprobing, but this is not same as
dracut config as i understand.
I never tried to branch kernel-source repo on obs to create custom
config, i can make this test also if you can give me please some
directions on how to properly create modified kernel branch.

Just tested lpae config without CONFIG_EXYNOS_IOMMU on snow, system
boots with black screen same,
then modprobe cros_ec_devs, ptn3460, pwm-samsung makes panel start
to
work without kernel panic.
Thanks for your tests.
Could you add thoses modules to
/etc/dracut.conf.d/exynos_modules.conf
with
the new line:
add_drivers += "cros_ec_devs ptn3460 pwm-samsung"
and recreate initrd with dracut and check if it boots fine?
If it does not work, try 'force_drivers+=' instead of 'add_drivers
+='
and
recreate initrd.

Hello Guillaume,
I tested both exynos_defconfig and multi_v7_defconfig, they work
fine.
But ill test lpae config without EXYNOS_IOMMU today and will

Hello,
Maybe we can disable only Exynos IOMMU in configs for now? Same
way
it
is disabled in current exynos_defconfig here
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/arch/arm/configs/exynos_defconfig?id=6562f3bd396ab6d2c9b455e95c67e33bab73bff5
As i understand it is broken for all exynos devices not only
snow.
That is exactly what I would like to do since I read this thread:
https://lkml.org/lkml/2015/2/17/163
Before submitting the idea here, I wanted to check if disabling
Exynos
IOMMU
in config was enough.
I had only time to test the exynos_defconfig with openSUSE kernel
and
it
was
OK (boot messages and login prompt displayed).

Maybe. Someone with a Chromebook needs to sit down and try.
:)
Hrm, rather than disable it one way or another manually,
couldn't
we
just blacklist it inside the kernel? I doubt that we can load
iommu
as
module...
You mean as in patch the iommu probe code to check for
"google,snow",
"google,spring", etc.?
For example - or remove the respective dt node. Or as a property
to
the
IOMMU dt node...
