Subject: [PATCH 0/6] PCI/ASPM: Add PCIe L1 PM substate support
Date: Mon, 2 Jan 2017 22:34:09 -0800 [thread overview]
Message-ID: <1483425255-101923-1-git-send-email-rajatja@google.com> (raw)
This patchset adds the PCIe L1 PM substate support to the kernel.
The feature is described at:
https://pcisig.com/sites/default/files/specification_documents/ECN_L1_PM_Substates_with_CLKREQ_31_May_2013_Rev10a.pdf
Its all logically one patch (and may be some of them should be
squashed later) , but I've broken down into smaller patches for
ease of review.
This is currently rebased on top of Bjorn's master branch.
Rajat Jain (6):
PCI: Add L1 substate capability structure register definitions
PCI/ASPM: Introduce L1 substates and a Kconfig for it
PCI/ASPM: Read and setup L1 substate capabilities
PCI/ASPM: Calculate and save the L1.2 timing parameters
PCI/ASPM: Actually configure the L1 substate settings to the device
PCI/ASPM: Add comment about L1 substate latency
