Has anyone applied this guide to the 9570 yet with success?

After a lot of trial and error, it looks like my camera and touchscreen are waking up the USB controller. If I either turn them off in BIOS, or just don't inject their ports in SSDT, I can remove any instant wake patch, go to sleep, and wake the laptop up with either a keypress or mouse button...

Do you have any insight as to why USB instant wakes the laptop? I'm interested in spending some time getting into the nuts and bolts to try to make it work properly.

@RehabMan I'm interested in getting sleep, and then wake from USB working on my Dell XPS 15 9550. It's my understanding that the current recommendation for laptops is still to apply your USB instant wake fixes to the DSDT. Have you ever seen a method to allow for proper USB sleep/wake? I'd like...

I'm attaching CLOVER.zip. I normally don't run with a patched DSDT (everything is hotpatched through Clover) but I had to patch DSDT to change the RP*/PXSX device names.

Ack, sorry. I had turned it back on to test. This behavior happens whether it is on or off.

I'm running a Dell XPS 9550. This behavior started after upgrading to 10.12.4. The laptop goes to sleep fine, but wakes up after a seeming random amount of time; it could be minutes or several hours. Here's the wake reason in the log (I've changed RP01/PXSX to 'SSD0', RP09/PXSX to 'ARPT', and...

The folks doing USB-C hot plug are likely using the SSDT-TB I created. I haven't seen anything else that remotely works. If you can point me in that direction, I'd like to see an alternative. And actually, it looks like hotplug with SSDT-TB works after sleep in 10.12.3! I'll type up the power...

No, the machine wakes up just fine. Could be a quirk of your laptop vs my 9550.

I just haven't had time to work on it; I've been focusing on fixing the Dell SMBIOS model identifier limit (a fix is coming out in the next release of Clover) and getting proper power management on my XPS 15 9550. I finally have X86PlatformPlugin loading with a MacBookPro13,3 model identifier...

An interesting side note: the OS is now fiddling with the HWP_REQUEST register. Specifically, when the laptop is on AC power, the energy performance preference byte fluctuates to either 0x20 or 0x80. I can't tell if it is correlated to load. When it's on battery, it stays at 0x80. It is also...

Turns out there was a bug in Clover r3994 that inverted the meaning of the 'Disabled' flag for kernel patches, it's been fixed in the svn repo. After building the latest Clover revision, @piker 's patch for xcpm_idle works. I'm now running a MacBookPro13,3 SMBIOS with vanilla X86PlatformPlugin...

How did you learn this stuff? I dug into the xnu code quite a bit while figuring the Dell SMBIOS stuff out, but not to that level... The xcpm_idle patch is a kernel patch, the first one I've tried to apply with Clover. I don't know if Clover is actually applying the patch properly since the...

Thanks, here you go. I should note that this happens whether I use the full SSDT generated by ssdtprgen, or just a small SSDT to only set the plugin-type property. Also I noticed that @piker published an 'xcpm_idle' kernel patch-- I tried it with Clover and it made no difference in my case.

I’m on a Dell XPS 15 9550 using 10.12.3 with a i7-6700HQ, one of the same CPUs present in the new 15" MacBook Pros. If I set the device property 'plugin-type' on CPU0 to 1 with a model identifier of MacBookPro13,3 (which should be correct for my CPU) and the OS loads X86PlatformPlugin, I get a...

Here's the method. I'll also attach the decompiled DSDT. Method (_E42, 0, NotSerialized) // _Exx: Edge-Triggered GPE { ADBG ("_E42") If (LEqual (CF2T, One)) { ADBG ("Clear") ADBG ("GPI_GPE_STS")...

If it only recurses once (which seems to be the case) would duplicating the method and patching the recursive call to call the duplicate not be sufficient? I'm admittedly a bit out of my depth here... the ACPI documentation is easy to follow, but when it comes to Dell's specific implementation...

2011 Macbook Pros and prior had ExpressCard slots. It looks like the code to support them is still in Sierra, but who knows when or if Apple will remove it. When you add _RMV = 1 to the RP15.PXSX device, it adds an IOPCIHotplug property in the IO registry. When you plug in a USB 3.1 device...

How would ExpressCards with USB controllers on them work? Or maybe a better question; how does macOS implement power management for USB controllers? Does it call any ACPI methods?

I have a Dell XPS 15 9550 but this may be applicable to other laptops as well. Apologies if this has already been fixed or discussed, but I could find very little information on it. The 9550's USB-C USB 3.1/TB3 port looks to be powered by a similar chip to the new Macbook Pros (the 15" has two...
