[PATCH 0/1] drm: i915: don't use OpRegion for XPS 13 IvyBridge

[Andrea Arcangeli]

I was bitten by this bug all last week while running latest kernels on
my laptop at KVMForum.

I then found the bug was also reported here:

[PATCH 1/1] drm: i915: don't use OpRegion for XPS 13 IvyBridge

[Andrea Arcangeli]

Skylake was already singled out, but it doesn't cover the XPS 13 L332X
model which is based on IvyBridge.

The commit that introduced the regression is
1d6da87a3241deb13d073c4125d19ed0e5a0c62c

The Skylake workaround for the regression was introduced in commit
aeddda06c1a704bb97c8a7bfe7a472120193bd56

If it's an Iybridge, there's no low vswing, and that explanation is
false. You can verify by trying i915.edp_vswing=1 or i915.edp_vswing=2
on an unpatched kernel.

Doesn't mean there can't be something else wrong with the mode you get
using a different panel_type. And this makes me wonder what the point is
in trying to patch up the commit instead of reverting.


BR,
Jani.

What I should look for when trying those two settings? Will they
successfully fix my problem with intel_backlight with upstream 4.8-rc?

I thought it had to be the same issue as on skylake as I get the
backlight flikering at low frequency but getting brighter and darker
in a cycle lasting a few seconds and I thought there couldn't be too
many other random bugs that ends up with the same side effect.

It looks like the hardware actually broke, software issue isn't the
first thing that comes to mind. As it's hard to imagine a timer in the
kernel reprogramming the backlight setting higher and lower just to
annoy me :). First in fact I thought at a plasma issue, but I tried to
downgrade the kernel first as that was quicker than downgrading
kde/plasma... I initially thought there were two userland daemons
stepping into each other toes.

Another thing is that if I keep decreasing the brightness the screen
eventually goes off and it returns on as I increase the backlight
level again (then low freq flickering starts). With acpi_video0 even
at the lowest brightness setting of 0, it never turns off the screen
completely.

Reverting the whole thing would be sure fine with me, I don't know
what the benefits there should be in using intel_backlight instead of
acpi_video0 like the previous code did, but I couldn't imagine too
many hw to behave like this if intel_backlight clearly has to work
stable for someone or it wouldn't exist in the first place.

This is just a "echo " into a backlight file if I tweak the backlight
settings... doesn't sound performance critical stuff to me, ACPI will
do just fine. However I'm not even sure how this problem could surface
in the first place without the kernel continuously reprogramming the
hw values.

Your Ivybridge does not have low voltage swing *and* low voltage swing
has nothing to do with the backlight. The regressing commit may be the
same for you, but the failure mode appears to be completely different.

Jani.

CC'ed Martin who filed the bz, he can reproduce too
https://bugzilla.kernel.org/show_bug.cgi?id=151731

Since you can reproduce would you have the time to test the two above
options on stock 4.7.x/4.8-rc and help tracking this down? I'm afraid
I won't be able to test it today and I'll be mostly offline for a week
starting tomorrow.

Thanks,
Andrea

Re: [PATCH 1/1] drm: i915: don't use OpRegion for XPS 13 IvyBridge

[Martin van Es]

Hi Andrea,

I'd be happy to test, but what am I testing when applying these boot 
parameters? In other words: what should I report?

And just to be sure, I THINK I own an IVB but intel is not very vocal about it 
when searching for familyname. I have a

vendor_id       : GenuineIntel
cpu family      : 6
model           : 58
model name      : Intel(R) Core(TM) i7-3537U CPU @ 2.00GHz
stepping        : 9
microcode       : 0x17

Regards,
Martin

The point is, for an ivybridge setting those parameters should not make
*any* difference.

Jani.

I can confirm that neither i915.edp_vswing=1 nor i915.edp_vswing=2 fixes the 
problem in 4.7.2 for me (intel_backlight devices takes precedence).

As I tried to explain, the low voltage swing is not related to backlight
issues.

Argh. I guess we'll just have to revert the whole opregion panel type thing
and ty to figure out some way to do this only for the system(s) that need it.

Hmm. Can someone test the top commit from [1] on top of the broken kernel?
If we can get an EDID somehow for the panel then the panel type shouldn't
matter that much any more.

Actually I just cooked up another branch [2]. It just throws in some
memory barriers to the opregion code, and adds a a new debug print so
to show the response from the BIOS. I'm not too optimistic that the
memory barriers would fix it, but at least we'd get to see the full
response from the BIOS. Can you give this a try?

And I've gone an pushed a potential fix to the same branch. So pleas try
it and let me know how it goes. And I still would like to see the dmesg
with drm.debug=0xe from that attempt.

This kernel doesn't boot (for me).

I cloned the repo, copied .config from 4.7 kernel, make oldconfig, accepted 
all defaults and made+installed the kernel. This installed an image 4.0.0-rc7+ 
(is that correct?) that was unbootable (halts at loading ramdisk).

Best regards,
Martin

The version should be 4.7 or 4.8 something. Maybe you used the wrong
branch?

Anywyas I pushed a new branch "opregion_panel_type_quirk" which I'm
hoping will be the final fix we go with. Just waiting for confirmation
that I got the quirk right and that the original machine fixed by the
OpRegion stuff still works. You might want to test that one as well.

Oh silly me and git. I thought I'd be checking out the correct branch on 
cloning that repo. I now checked out opregion_panel_type_quirk branch and that 
resulted in a 4.8.0-rc5+ kernel.

Booting that kernel resulted in a correct functioning backlight based on 
acpi_video0 driver. Graphics glitches however were so bad I had to reboot into 
4.7.3 to write this mail.

dmesg of 4.8.0-rc5+ boot with drm.debug=0xe attached.

Best regards,
Martin

Thanks Martin.

I was in vacation last week, let me know if you need me to test as
well but me and Martin are reproducing the exact same issue so I
believe his testing should have provided all info needed for now.

While talking about graphics glitches this reminds I'm getting
corrupted graphics on terminals (sandy bridge HD3000) with any intel
driver >=x11-drivers/xf86-video-intel-2.99.917_p20160803

I had to add:

cat /etc/portage/package.mask/x11
>=x11-drivers/xf86-video-intel-2.99.917_p20160803

Last working version for me is:

qlist -I -v video-intel
x11-drivers/xf86-video-intel-2.99.917_p20160704

That is most certainly an unrelated issue with the backlight, and I'm
not even sure if it affects the Ivy Bridge laptop with hd4000, as I
ended up never testing anything above 2.99.917_p20160704 on it. But in
my experience you may want to try to downgrade the xorg intel video
driver version too if you get graphic glitches.
