Hi Lukas, Sorry for the delay, I finally found some time to reviewd and test the patches and found some issues (some of them might already be present in v4.15 without your patches though, I did not try). Test environment: - Branch switcheroo_devlink_v2 (commit v4.15-20-gb33d50c5c6ad) - Laptop: Clevo P651RA (nouveau uses PR3), lspci: 00:01.0 PCI bridge [0604]: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor PCIe Controller (x16) [8086:1901] (rev 07) 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GM204M [GeForc...

...ore machines would be greatly appreciated, particularly Nvidia Optimus or AMD PowerXpress. The series is based on 4.16-rc3. To test it on 4.15, you need to cherry-pick 7506dc798993 and 2fa6d6cdaf28. For your convenience I've pushed a 4.15-based branch to: https://github.com/l1k/linux/commits/switcheroo_devlink_v2 Minimal test procedure: - Note well: Recent Optimus require that a Mini-DP or HDMI cable is plugged in on boot for the HDA device to be present. - Check that HDA, GPU and root port autosuspend when not in use: cat /sys/bus/pci/devices/0000:01:00.1/power/runtime_status # HDA cat /sys/bus/p...
