Hi Bjorn, Today's linux-next merge of the pci tree got a conflict in drivers/pci/pci.c between commit c2fb8a3fa255 ("USB: add NO_D3_DURING_SLEEP flag and revert 151b61284776be2") from Linus' tree and commit 448bd857d48e ("PCI/PM: add PCIe runtime D3cold support") from the pci tree. I fixed it up (I think - see below) and can carry the fix as necessary. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au diff --cc drivers/pci/pci.c index 77cb54a,3f8b74f..0000000 --- a/drivers/pci/pci.c +++ b/drivers/pci/pci.c @@@ -1744,11 -1803,10 +1803,15 @@@ int pci_prepare_to_sleep(struct pci_de if (target_state == PCI_POWER_ERROR) return -EIO; + /* D3cold during system suspend/hibernate is not supported */ + if (target_state > PCI_D3hot) + target_state = PCI_D3hot; + + /* Some devices mustn't be in D3 during system sleep */ + if (target_state == PCI_D3hot && + (dev->dev_flags & PCI_DEV_FLAGS_NO_D3_DURING_SLEEP)) + return 0; + pci_enable_wake(dev, target_state, device_may_wakeup(&dev->dev)); error = pci_set_power_state(dev, target_state);
