[SOLVED] Cannot allow DC9 without disallowing DC6

[m0d16l14n1]

Hello! Got problem with my hackintosh
Laptop - Ice Lake laptop (i7-1065G7).

Problem with waking from sleep. Sleep is kinda working on some framebuffers, the best I get with the 0x8A5C0002 (lid sleep is working / lid wake is randomly working / fn+esc (sleep button) not working, causing the same panic, as lid wake sometimes causing). On default framebuffer for Ice Lakes (0x8A520000) sleep is working "well" from sleep button and randomly with lid, but after wake screen is off, I can't turn it on at all. After shutdown - sometimes I have same panic as well. So I started to trying different framebuffers and first I checked was 0x8A5C0002, as I already told - lid sleep become better, I can put laptop in sleep and wake it with lid, but if I try to put it in sleep for second time - it won't sleep, screen is off, after reboot - I got panic. So, the problem with screen sleep/wake up as I understood.

Also will provide my EFI (latest release of debug OC, latest kexts)

P.S. BIOS of laptop is unlocked, I have bunch of settings of CPU/GPU management, maybe it will be helpful too. I can provide screenshots of it, if it's needed. Sorry for my English, that's not my native language

Well, this seems to say that it cannot go directly from a deeper power state without going through an intermediate one. Pretty honest. The fact that it does try that may mean that the BIOS is waking up your IGPU in an unexpected DC state or there is some race condition in the driver maybe?

I do not believe WEG currently has anything to workaround this, but maybe @07151129 or @0xFireWolf could add anything.

Thanks for the answer. Found the same case with Asus Vivobook here

Try using bootargs -noDC9 or -nodisplaysleepDC6

[m0d16l14n1]

Try using bootargs -noDC9 or -nodisplaysleepDC6

-noDC9 seems to be working. Lid sleep is okay, sleep button is ok, sleep from menu is okay. After sleep display is turning on, after second cycle of sleep testing - laptop is going to sleep mode and after wake display is turning on (usually second cycle is going to panic). So it's working, heh! Thanks! I will test it today for more time and will also test -nodisplaysleepDC6, just to check if it's okay to use it or only -noDC9 works

[m0d16l14n1]

Laptop slept over 15 times with different timings, also i check with putting laptop in sleep mode overnight, so it's seems working stable. (discharged for 4% overnight sleep). -noDC9 is working. Thanks again!

Try using bootargs -noDC9 or -nodisplaysleepDC6
