[PATCH v4 0/9] PCIe speed changes
...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.

[PATCH 0/5] Potential fix for runpm issues on various laptops
...nning it on vbios provided signed PMU image, but on the devinit parser we have inside Nouveau. Allthough this one isn't as feature complete as the vbios one, I was able to reproduce the runpm issues as well. From that point I was able to only run a certain amount of commands until I got to some PCIe initialization code inside devinit which trigger those runpm issues. Devinit on my GPU was changing the PCIe link from 8.0 to 2.5, reversing that on the fini path makes runpm work again. There are a few other things going on, but with my limited knowledge about PCIe in general, the change in the...

[PATCH 0/3] PCIe link change improvements
everything was taken from nvgpu. Main reason for adding is to improve stability of the PCIe link changing code as we might want to depend on it for a workaround fixing our infamous runpm issues on recent laptops Karol Herbst (3): pci: force disable ASPM before changing the link speed pci/gk104: enable dl_mgr safe mode pci/gk104: wait for ltssm idle before changing the link drm/n...

[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 changing the link speed pci/gk104: enable dl_mgr safe mode pci/gk104: wait for ltssm idle before changi...

[PATCH v4 0/4] add PCIe workaround to fix runpm on laptops
...e 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.

[PATCH v2 4/4] pci: save the boot pcie link speed and restore it on fini
Apperantly things go south if we suspend the device with a different PCIE link speed set than it got booted with. Fixes runtime suspend on my gp107. This all looks like some bug inside the pci subsystem and I would prefer a fix there instead of nouveau, but maybe there is no real nice way of doing that outside of drivers? v2: squashed together patch 4 and 5 Signed-of...

[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...
