dmesg
Hardware: MacBook Pro 11,3 with i7-4850HQ, an Intel Iris Pro 5200 and an NVIDIA GeForce GT 750M
Architecture: x86_64
Kernel version: 4.8.5
Distribution: ArchLinux
Most likely related: https://bugs.freedesktop.org/show_bug.cgi?id=90014
I need to patch my kernel to actually be able to use the integrated GPU, as otherwise the EFI firmware turns it off (see http://lists.gnu.org/archive/html/grub-devel/2014-11/msg00034.html).
With the IGD activated and the i915 driver loaded, there is one kworker using one core at 70% all the time, and acpi/interrupts/gpe06 growing continuously increasing. With the IGD activated but i915 has not been loaded, then gpe06 remains at 0 interrupts and there are no kworker using more than 5%.
