but setting the PCI_DEV_FLAGS_NO_D3 flag does prevent using the platform means of putting the device into D3cold, right? That's actually what should still happen, just the D3hot step should be skipped. On Wed, Oct 16, 2019 at 9:14 PM Bjorn Helgaas <helgaas at kernel.org> wrote: > > On Wed, Oct 16, 2019 at 04:4...

...in a number of places how to fix this issue, and indeed here: http://filedownloads.qlogic.com/files/driver/48437/README_qla2xxx2-6U4.htm#BlacklistEntries Apparently, I should be able to add a line to modprobe.conf that allows sparse LUNs. So I followed the instructions and added options scsi_mod dev_flags="SUN:CSM200_R:0x040" max_luns=20 and rebuilt initrd. This doesn't seem to work, as only LUN 0 is configured by the OS despite LUN 9 also being unmasked. I've also tried options scsi_mod default_dev_flags=0x040 max_luns=20 in modprobe.conf with no luck [root at host qlogic]#...

I would put the parent_broken_child_pm() logic here, if possible, e.g., something like: struct pci_dev *bridge = pci_upstream_bridge(dev); if (bridge && bridge->vendor == PCI_VENDOR_ID_INTEL && bridge->device == 0...

Fixes state transitions of Nvidia Pascal GPUs from D3cold into higher device states. v2: convert to pci_dev quirk put a proper technical explanation of the issue as a in-code comment v3: disable it only for certain combinations of intel and nvidia hardware Signed-off-by: Karol Herbst <kherbst at redhat.com> Cc: Bjorn Helgaas <bhelgaas at google.com> Cc: Lyude Paul <lyude at

...ex). The solution was to introduce a new "pci_reset_function": [PATCH 1/5] pci: Introduce __pci_reset_function_locked to be used and then piggyback on that in [PATCH 2/5] xen/pciback: Support pci_reset_function, aka FLR or D3 Also there are two fixes included in this - one where the PCI_DEV_FLAG_ASSIGNED was in the wrong location and the "device has been assigned to other domain" warning that always appeared.
