[PATCH v2 0/4] Potential fix for runpm issues on various laptops
CCing linux-pci and Bjorn Helgaas. Maybe we could get better insights on how a reasonable fix would look like. Anyway, to me this entire issue looks like something which has to be fixed on a PCI level instead of inside a driver, so it makes sense to ask the pci folks if they have any better suggestions. Original cover letter: While investigating the runpm issues on my GP107 I noticed that

[PATCH 0/7] Adding a proper workaround for fixing RTD3 issues with Nouveau
First three patches are removing ACPI workarounds which should have never landed. The last four are adding a workaround to nouveau which seem to help quite a lot with the RTD3 issues with Nouveau, so let's discuss and get wider testing of those and see if there is any fallout or laptops where the issues don't get fixed.

[PATCH v4 0/4] add PCIe workaround to fix runpm on laptops
not much changed since the last time I sent those patches out, but there are a couple of annoying bug fixes, which users would probably never hit unless they do rmmod/modprobe nouveau cycles. Biggest change is that I force the link to a 8.0 speed rather than the speed the GPU came up with. Also this series depends on the PCIe improvement patches I sent out recently. Karol Herbst (4): pci:

[PATCH 0/6] Add workaround for fixing runpm
I merged the both series I sent out recently into one bigger one so that it's more obvious on why all of that is needed. Biggest changes since last sent: * reworked the ASPM patch * removed "pci: add nvkm_pcie_get_speed" patch Please test this on Laptops and report back if it either breaks something or doesn't fix runpm. Thanks Karol Herbst (6): pci: disable ASPM before

[PATCH v4 0/9] PCIe speed changes
overall it is for the most part the same as my older version. I cleaned up some copyright things, so that it is more like the others. Also I moved the print about the max speed supported into preinit and did some other minor cleanups in the 3rd commit. Happy testing (and performance for prime offloading setups) Karol Herbst (9): pci: add gk104 variant pci: add gf106 variant pci: implement

[PATCH v2 4/4] pci: save the boot pcie link speed and restore it on fini
@bjorn: any further ideas? Otherwise I'd like to just go ahead and fix this issue inside Nouveau and leave it there until we have a better understanding or non Nouveau cases of this issue.

[PATCH 0/8] Add workaround for fixing runpm
Changes since last sent: * add a patch to set the device into DRM_SWITCH_POWER_CHANGING state (can be dropped actually, I thought I was needing it, came up with a different approach and forgot to delete it, doesn't hurt though) * expose information about runtime suspending to nvkm so that we can run the pcie workaround only on runtime suspend Karol Herbst (8): pci: disable ASPM

[PATCH v2 4/4] pci: save the boot pcie link speed and restore it on fini
Hi Bjorn, I was playing around with some older information again (write into the PCI config to put the card into d3 state). And there is something which made me very curious: If I put the card manually into any other state besides D0 via the 0x64 pci config register, the card just dies and pci core seems to expect this to not happen. pci_raw_set_power_state has this
