DW1560 WiFi + BT. I'm experiencing BT Lag when using with 2.4Ghz WiFi. Anyone else?
@RehabMan - Since 10.12.6 has been released I haven't succeeded in getting the native KBL framebuffer driver to work properly with my UHD display. My DVMT in BIOS is set to pre-allocate 64MB. The display boots up fine (it's in 1600x900 in Retina mode) but when the screen turns off or laptop goes to sleep the display either does not come back or comes back garbled. It works fine with the SKL framebuffer driver though.
Windows reports the device as having an ID of 59168086.
Here's what I've tried to do:
1) Change ig-platform-id to 591b0000 & FakeID to 59168086 With the 19MB framebuffer patch the display fails to initialise; I subsequently amended the kext patch to 64MB, the display starts up correctly but then fails to come back on sleep or screen-off.
2) Change ig-platform-id to 59160000 & FakeID to 59168086. Display starts up fine but fails to come back on sleep or screen-off.
3) Change ig-platform-id to 19160000 & FakeID to 19168086. Display works correctly and resumes properly.
4) Increase DVMT in BIOS to 96MB or 128MB. No effect.
I've attached my problem reporting files.
Try other ig-platform-ids. Suggest you extract all of them from the binary and try each.
For some of them, you may need to increase DVMT-prealloc.
Also, an ioreg from a retina KabyLake MacBookPro might be useful. Perhaps there is some property we should be injecting. And it would tell us which ig-platform-id is being used.
Will do.
Would you suggest a different SMBIOS to Macbook9,1?
After some testing, MacbookPro14,3 solves the issue on my i7-7500U with UHD. ig-platform-id is set to 591b0000, and the system works with HWP set on or off.
In so doing I've extracted a number of other ig-platform-id from the binary. Haven't tested them but here they are:
59120000
591B0000
591B0006
591D0000
591E0000
591E0001
59230000
59260000
59260002
59270000
59270004
59270009
