Yes, it fixes that for a number of people, which is the reason why I send
the pull request in the first place, but it also turns out to break things
for some people and therefore it'll have to be reverted.
We're still going to work on that, though.
Thanks,

If you have new patches ready for this and you want them to be tested,
let me know!

Before the changes backlight was working fine using the ACPI method:
/sys/class/backlight/acpi_video0/ is present and the keyboard function keys
control brightness with notifications working in GNOME.
In the code as was present in the linux-pm/bleeding-edge tree I would
encounter a hard lockup on keyboard brightness trigger. This also occurred with
the code as it initially hit mainline, but a later commit fixed the crash*, but
resulted in no backlight controls being available at all.
/sys/class/backlight is empty.
*not actually sure if /sys/class/backlight contained anything before this

Hi Rafael-
For your reference...
As James Hogan reported, those ACPI changes break backlight control on
the "Dell XPS13" Ivy Bridge models (the Sandy Bridge XPS13 model is not
affected).
I confirm that reverting 8c5bd7a and efaa14c fixes it again.
Also FYI...

That patch is now queued up in drm-intel/drm-intel-fixes, so should be
making its way to mainline soon.

This is an Intel system using the i915 driver?

Thanks!
I'd like to collect some information on the systems having problems with those
two commits (to see if they are similar somehow).
It seems that one common symptom is that brightness cannot be controlled
through function keys. Is that correct for all of you? If so, did you try
any other way to control brightness, like a GUI-based?
Also, can you all please send me (a) the output of dmidecode and (b) the
contents of /proc/cpuinfo from your systems?

For me both the Fn keys and the gui slider (kde) now control
/sys/class/backlight/intel_backlight/brightness (which has no effect).
Previously they both controlled the acpi one (that on -rc2 doesn't
exist).

Hm, poking Fn keys make kde slider widget appear on my Toshiba Satellite
but do nada, never did, and I never looked into it, assumed there was no
canned functionality for my lappy, so use a setpci script instead.
Lappy has acpi_video0, which gui is twiddling, and does nothing, as does
toshiba, while intel_backlight works.
Suppose I should put latest/greatest kernel on the thing, maybe my Fn
keys will magically start turning the _right_ knob.

I think this problem in i915 drivers.

Yes, it is my impression too.

OK, time to revert I guess.
James, Kamal, Steven, Jörg, Martin, Kalle, please check if the apppended patch
fixes the backlight for you.
Aaron, please double check if acpi_video_backlight_quirks() will still work as
needed.
Thanks,

Subject: Revert "ACPI / video / i915: No ACPI backlight if firmware expects Windows 8"
We attempted to address a regression introduced by commit a57f7f9
(ACPICA: Add Windows8/Server2012 string for _OSI method.) after which
ACPI video backlight support doesn't work on a number of systems,
because the relevant AML methods in the ACPI tables in their BIOSes
become useless after the BIOS has been told that the OS is compatible
with Windows 8. That problem is tracked by the bug entry at:
https://bugzilla.kernel.org/show_bug.cgi?id=51231
Commit 8c5bd7a (ACPI / video / i915: No ACPI backlight if firmware
expects Windows 8) introduced for this purpose essentially prevented
the ACPI backlight support from being used if the BIOS had been told
that the OS was compatible with Windows 8 and the i915 driver was
loaded, in which case the backlight would always be handled by i915.
Unfortunately, however, that turned out to cause problems with
backlight to appear on multiple systems with symptoms indicating that
i915 was unable to control the backlight on those systems as
expected.
For this reason, revert commit 8c5bd7a, but leave the function
acpi_video_backlight_quirks() introduced by it, because another
commit on top of it uses that function.

> Commit 8c5bd7a (ACPI / video / i915: No ACPI backlight if firmware

> the ACPI backlight support from being used if the BIOS had been told
> that the OS was compatible with Windows 8 and the i915 driver was

Yes, this revert patch does re-enable backlight control for the affected
Dell XPS13 models.

Are these the same models that neeed the special quirk to not write
PCH_PWM_ENABLE? Or do they need both?

Hi Daniel-
Yes, these are the same models (Dell XPS13) that need the PCH_PWM_ENABLE
quirk, but that's not related to this ACPI problem...
All of the XPS13 models still need the PCH_PWM_ENABLE quirk which is now
present in mainline (e85843b "drm/i915: quirk no PCH_PWM_ENABLE for Dell
XPS13 backlight").
Separately from that, some of the XPS13 models were _also_ adversely
affected (as were some other machines) by the ACPI changes that are
about to be reverted.

Ok, with the help of Kamal I got my source tree back to a consistent
state. The patch now applies successfully.
Rafael, I now can confirm the patch fixes the problems for me.

Great!
James, Kamal, Jörg, thanks for confirmations. I'll tentatively put the revert
into linux-next in a while.
Other people who experienced problems with backlight in 3.11-rc2, please let me
know whether or not the revert works for you too if you can.

Before reverting the patch /sys/class/backlight was empty and backlight
brightness was set to max, now it again contains a link to acpi_video0
on my Thinkpad 420s with intel video and adjusting the backlight works
again.

Works fine for me.

By the way, I'm willing to test any i915 backlight patches if it helps.

Rafael, do you still need more testing urgently? Otherwise I´d wait till its
in some next 3.11 rc and test then.

reports!), so I don't think you need to test it urgently.
