Subject: [PATCH v9 0/5] Simplify PCIe native ownership detection logic
Date: Tue, 22 Sep 2020 13:54:27 -0700 [thread overview]
Message-ID: <cover.1600457297.git.sathyanarayanan.kuppuswamy@linux.intel.com> (raw)
From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>
Currently, PCIe capabilities ownership status is detected by
verifying the status of pcie_ports_native, pcie_ports_dpc_native
and _OSC negotiated results (cached in struct pci_host_bridge
->native_* members). But this logic can be simplified, and we can
use only struct pci_host_bridge ->native_* members to detect it.
This patchset removes the distributed checks for pcie_ports_native,
pcie_ports_dpc_native parameters.
Changes since v8:
* Simplified setting _OSC ownwership logic
* Moved bridge->native_ltr out of #ifdef CONFIG_PCIEPORTBUS.
Changes since v7:
* Fixed "fix array_size.cocci warnings".
Changes since v6:
* Created new patch for CONFIG_PCIEPORTBUS check in
pci_init_host_bridge().
* Added warning message for a case when pcie_ports_native
overrides _OSC negotiation result.
Changes since v5:
* Rebased on top of v5.8-rc1
Changes since v4:
* Changed the patch set title (Original link: https://lkml.org/lkml/2020/5/26/1710)
* Added AER/DPC dependency logic cleanup fixes.
Kuppuswamy Sathyanarayanan (5):
PCI: Conditionally initialize host bridge native_* members
ACPI/PCI: Ignore _OSC negotiation result if pcie_ports_native is set.
ACPI/PCI: Ignore _OSC DPC negotiation result if pcie_ports_dpc_native
is set.
PCI/portdrv: Remove redundant pci_aer_available() check in DPC enable
logic
PCI/DPC: Move AER/DPC dependency checks out of DPC driver
