Subject: [PATCH v2 0/2] PCI: Power management improvements
Date: Wed, 12 Jun 2019 13:57:37 +0300
Message-ID: <> (raw)

Hi all,

This series includes a couple of changes to the PCI power management that
should make Linux follow the PCIe spec better. The issues this series aims
to solve came up with Intel Ice Lake Thunderbolt enabling where the
controller is first time integrated into the SoC but I think these issues
are generic to any platform having similar configuration.

Changes from v1

  * I dropped the last patch as it requires bit more work and not dependent
    on the other two. I will send it out separately.
  * Re-arranged conditionals in wait_for_downstream_link()
  * Moved comments to be part of kernel-doc
  * Added tags from Rafael and Lukas

Previous version is here:

Mika Westerberg (2):
  PCI: Add missing link delays required by the PCIe spec
  PCI: Do not poll for PME if the device is in D3cold
