[REGRESSION BISECTED] backlight control stops workin with 3.14 and later
(too old to reply)

Hi Jani et al,

A friend of mine Bertrik Sikken (in the Cc) his backlight control
stopped working for him on his Samsung N150Plus netbook.

I took a quick look, and the raw intel_backlight backlight interface
works under 3.14, but the firmware samsung_laptop backlight interface,
which is what most userspace apps will use by default, stops working
in 3.14 .

I've asked him to bisect this and the bisect points out this
commit as the culprit:

b35684b8fa94e04f55fd38bf672b737741d2f9e2 is the first bad commit
commit b35684b8fa94e04f55fd38bf672b737741d2f9e2
Author: Jani Nikula <***@intel.com>
Date: Thu Nov 14 12:13:41 2013 +0200

drm/i915: do full backlight setup at enable time

We should now have all the information we need to do a full
initialization of the backlight registers.

v2: Keep QUIRK_NO_PCH_PWM_ENABLE for now (Imre).

Signed-off-by: Jani Nikula <***@intel.com>
Reviewed-by: Imre Deak <***@intel.com>

Note that this laptop has an acpi_video backlight interface too,
but that has been broken from the start and gets disabled by
samsung-laptop based on dmi matching.

Hans

How does the intel backlight fare? Please test both 3.14 and 3.15 and
also test what happens when you blacklist the samsung-laptop driver
(if that's possible without wreaking the machine).

Also please grab latest intel-gpu-tools and record a register dump
with intel_reg_dump, again for both broken and working kernels.

What would be useful here would be dumping the regs when we takeover (and
our interpretation for ease of reading). Basically the question here is
what does the samsung backlight driver do - and the suspicion is that it
uses the combination mode and we don't set that up...

That works fine with 3.14 .

(if that's possible without wreaking the machine).
Then the vendor interface won't get promoted, acpi-video will load,
and things likely will not work.

Bertrik, can you try blacklisting the samsung-laptop module, then
check /sys/class/backlight, the samsung_laptop dir should be gone
replaced by an acpi_video0 (or some such) dir. Please try if that
works. If that does not work, try booting with both the module
blacklisted and "acpi_backlight=vendor" on the kernel commandline,
then you should see only the intel-backlight under /sys/class/backlight
and things should work.

With linux kernel v3.14 and the samsung_laptop module blacklisted,
I indeed see a /sys/class/backlight/acpi_video0, but changing brightness
by writing (as root) to the brightness file does not have an effect.

Additionally, with the acpi_backlight=vendor kernel command line option,
there is only an intel_backlight directory in /sys/class/backlight.
Brightness does work using "brightness up and down" function keys,
with 'udevadm monitor' I can see it uses the intel_backlight:

***@netbook:~$ udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

KERNEL[40.375921] change
/devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/intel_backlight
(backlight)
UDEV [40.503704] change
/devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/intel_backlight
(backlight)

Attached is dmesg output from booting kernel 3.14-2 (debian unstable)

If you need anything else, please let me know.

Attached is dmesg output from booting kernel 3.14-2 (debian unstable)
with drm.debug=0xe and the samsung_laptop module enabled, from my
Samsung N150plus netbook.
Have you tried 3.15?
I've built the v3.15 kernel (using the .config file from debian
unstable and doing make oldconfig).

The backlight is at maximum brightness after boot and I can't control
it using the backlight buttons, nor by writing to
/sys/class/backlight/samsung/brightness
(say half the value or 1/10th of max_brightness)

Backlight does work when writing
/sys/class/backlight/intel_backlight/brightness

Kind regards,

How about disabling samsung backlight module with 3.15?

I'm not sure what you mean by that.

As I understand it, there are three ways to control the backlight on this
netbook: using intel_backlight, samsung_laptop (using a "sabi" interface)
and acpi_video.
Backlight control using the samsung_laptop driver no longer seems to work
after the change. If I disable it (e.g. by blacklisting it), I expect it
to no longer work at all obviously.

What do you want me to test exactly?

Kind regards,

Attached is dmesg output from booting kernel 3.14-2 (debian unstable)
with drm.debug=0xe and the samsung_laptop module enabled, from my
Samsung N150plus netbook.
Have you tried 3.15?
I've built the v3.15 kernel (using the .config file from debian
unstable and doing make oldconfig).
The backlight is at maximum brightness after boot and I can't control
it using the backlight buttons, nor by writing to
/sys/class/backlight/samsung/brightness
(say half the value or 1/10th of max_brightness)
Backlight does work when writing
/sys/class/backlight/intel_backlight/brightness
How about disabling samsung backlight module with 3.15?
I'm not sure what you mean by that.
As I understand it, there are three ways to control the backlight on this
netbook: using intel_backlight, samsung_laptop (using a "sabi" interface)
and acpi_video.
Backlight control using the samsung_laptop driver no longer seems to work
after the change. If I disable it (e.g. by blacklisting it), I expect it
to no longer work at all obviously.
What do you want me to test exactly?
If the intel_backlight interface works in 3.15, I presume the problem is
that you have a non-functional samsung backlight interface that is
preferred over intel_backlight by your userspace.

BR,
Jani.

backlight module blacklisted. The intel_backlight interface still works.

The problem as I see it, is that the bisected backlight change in the
intel-gfx driver caused the samsung_laptop backlight mechanism to break,
while they apparently were able to play nice with each other before.

You could consider having two drivers trying to access the same hardware
as a more general linux kernel bug. As I understand it now, the intel-gfx
driver talks directly to the hardware and the samsung_laptop driver talks
through a BIOS interface (SABI = "Samsung advanced BIOS interface").

I'm not trying to put the blame on any of the two drivers, just looking
for the best solution to a practical problem.

No, just NO. This thread has "REGRESSION" in the subject for a reason,
userspace will prefer a firmware backlight interface over a raw backlight
interface, so the only way to get userspace to use the intel backlight
driver is to blacklist the samsung_laptop and acpi_video (Bertrik can you
confirm that acpi_video also is broken?) so that the intel one is the only
remaining.

Now in some cases that is the right answer, it is actually what we do for
all laptops with win8 "ready" BIOS-es as the firmware interfaces tend to
be broken there, but that is not the case here.

The samsung_laptop backlight interface used to work, and at a minimum we
need to figure out exactly _why_ it stopped working.

We could possibly fix things for Bertrik by a dmi based quirk, but this
problem will likely apply to all samsung netbook devices from the same
era and there are a _lot_ of different models from those, and the problem
may also apply to other vendor laptops too. Doing a dmi string based quirk is
just papering over the problem, and thus is unacceptable IMHO.

Hans

Fair enough.

I'm going to need a bunch of attached files that will be awkward on the
mailing list, so please file a new bug against DRM/Intel at [1]. Refer
this mail thread, and attach the output of intel_reg_dumper (from
intel-gpu-tools [2]) on a working and a non-working kernel. Also attach
/sys/kernel/debug/dri/0/i915_opregion

On the broken kernel, does the samsung backlight interface work *before*
you've loaded i915.ko?

Thanks,
Jani.
