[FIX] enable lid wake from sleep for Skylake Iris Graphics

syscl · November 15, 2016

Hola, I just got my own XPS 13 9350 with Iris 540 graphic card, and soon found out that I cannot light my lid up when resume from sleep, finally, I found out the solution.

Edited 2016-12-09:

Now I found out the secret is the 0A -> 0F fixed the sleep issue(no more 2 stage patches), thus refine patch

Rebuild kernel cache by the following under Sierra

sudo rm -rf /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache
sudo rm -rf /System/Library/PrelinkedKernels/prelinkedkernel
sudo touch /Library/Extensions && sudo touch /System/Library/Extensions && sudo kextcache -u /

Reboot to enjoy the laptop sleep

Amazing work Can you also port the patch for HD520/HD530 framebuffer ?

I'll try to figure out HD530/520's issue, since I haven't had device with HD530/520, so I have to experiment.

And I have too many homework this days, sorry for my late response.

Hi syscl, Is the dsdt patch different from the regular dsdt patch for GFX0 -> IGPU? If not, will I need to patch it again the clover? Since it can boot normally (but with some issues, long story )

The lid wake up patch means when we open the laptop? or just power on?

What I've tried :

- Using regular DSDT patch for GFX0 -> IGPU (so not using our clover patch)

- Using your lid wake up patch

- Change the intel id graphics to 0x1926004

- use pmset -a hibernatemode 0 (is this still needed?)

Result :

- @cold boot, black screen and power off after apple progress screen in the middle, (I think its shutdown but its not, seems like go into sleep mode), when I press power button, it will light up and go into login screen

- After sleep, when I open the lid, it wont run, until I press power button, and it will go into login screen

- The wifi dongle I use is suddenly automatically reconnect (usually i have to remove and reinsert it), dont know if this because of your lid wake up patch (havent used your usb wake up fix patch yet)

Strange things :

- After woke up, when I put on the power adaptor, the screen will black and dont know what to do so I just press power until shutdown

- Today it crashed after woke up and wifi working, about 5 secs it just restarted on its own

Any tips ? Thanks for everything

I do not know what specs your ops 13 9350 is, but in my case(Iris 540 graphics card), once I open the lid, screen is lighted up as a real MacBook.

Pay attention, when you switch ig-platform-id, you will get mixed result, that's the reason why I pointed out you have to rebuild the kernel cache before reboot.

Hibernatemode won't affect the patches I developed, but you can switch to hibernatemode = 0 to boost the wake up progress. I do not know why Skylake's wake up progress is much slower than M3800 in macOS. It always took me about 3~4s to wake the login screen up(In M3800 this progress is almost instant). Maybe due to nvme. I will look into this problem later.

About restart, you have to apply HaltEnabler = Yes to fix the reboot issue.

I still have copious amount of ACPI patch for XPS 13 9350 and thanks for a friend with MacBook give me all the ACPI information I want, so just wait for https://github.com/syscl/XPS9350-macOSto finish.

Yeah this is certainly due to NVMe. Nevertheless for more details on this sorry I don't know... I guessed that something went wrong with Pike's NVMe patch. And could get an instant wake on my New MacBook 2016 (SKL based) with HibernateMode = 0. Anyway. Log will tell. Just check what is happening when waking up. And the friend is me? LOL

Which ig-platform-id do you use?

I have to upload the patch for specific ig platform

NO, another friend gave me the ioreg. Yours may be in desktops pc which are thousands mile away.

Hi. I know it is an old thread, but I need some help with returning from sleep on my laptop (Dell 5557).

When I open my lid, system come back from sleep with the screen turned off. I need to press a key on keyboard or press the power button again to make the screen on again.

Does it has anything related to this patch?

If so, could you please help me making a patch specific to my Graphic Card?

I am using ig-platform-id 0x19160000 for Intel® HD Graphics 520.

Thanks.

You have to disable PowerNap.

Hi syscl,

I'm trying to port your patch to platform id 0x191b0000, but one thing I can't figure out is how you determined 0x0A needs to become 0x0F. It looks like for 0x191b0000 the corresponding value is already 0x0F (0F110000 while for your platform it's 0A0B0300), however when I open the lid I still must press a button on the keyboard in order to bring up the login screen. Could you provide any insight? I'm talking about the same thing Drfrag mentioned above.

Also, Slice, disabling Power Nap does not solve that for me.

Hi, please use boot argument: darkwake=0 to solve this "issue". Report here.

KNNSpeed · June 11, 2017

Darkwake=1 wound up doing the trick.

From https://opensource.apple.com/source/xnu/xnu-3789.51.2/iokit/Kernel/IOPMrootDomain.cpp.auto.html

// gDarkWakeFlags
enum {
kDarkWakeFlagHIDTickleEarly = 0x01, // hid tickle before gfx suppression
kDarkWakeFlagHIDTickleLate = 0x02, // hid tickle after gfx suppression
kDarkWakeFlagHIDTickleNone = 0x03, // hid tickle is not posted
kDarkWakeFlagHIDTickleMask = 0x03,
kDarkWakeFlagAlarmIsDark = 0x0100,
kDarkWakeFlagGraphicsPowerState1 = 0x0200,
kDarkWakeFlagAudioNotSuppressed = 0x0400
};

Thanks for responding!

i know its an old thread, but did you ever fix HD520? I cant get lid wake to work for the life of me.
