Subject: [PATCH v12 0/8] Add Error Disconnect Recover (EDR) support
From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@...ux.intel.com>
This patchset adds support for following features:
1. Error Disconnect Recover (EDR) support.
2. _OSC based negotiation support for DPC.
You can find EDR spec in the following link.
https://members.pcisig.com/wg/PCI-SIG/document/12614
Changes since v11:
* Allowed error recovery to proceed after successful reset_link().
* Used correct ACPI handle for sending EDR status.
* Rebased on top of v5.5-rc5
Changes since v10:
* Added "edr_enabled" member to dpc priv structure, which is used to cache EDR
enabling status based on status of pcie_ports_dpc_native and FF mode.
* Changed type of _DSM argument from Integer to Package in acpi_enable_dpc_port()
function to fix ACPI related boot warnings.
* Rebased on top of v5.5-rc3
Changes since v9:
* Removed caching of pcie_aer_get_firmware_first() in dpc driver.
* Added proper spec reference in git log for patch 5 & 7.
* Added new function parameter "ff_check" to pci_cleanup_aer_uncorrect_error_status(),
pci_aer_clear_fatal_status() and pci_cleanup_aer_error_status_regs() functions.
* Rebased on top of v5.4-rc5
Changes since v8:
* Rebased on top of v5.4-rc1
Changes since v7:
* Updated DSM version number to match the spec.
Changes since v6:
* Modified the order of patches to enable EDR only after all necessary support is added in kernel.
* Addressed Bjorn comments.
Changes since v5:
* Addressed Keith's comments.
* Added additional check for FF mode in pci_aer_init().
* Updated commit history of "PCI/DPC: Add support for DPC recovery on NON_FATAL errors" patch.
Changes since v4:
* Rebased on top of v5.3-rc1
* Fixed lock/unlock issue in edr_handle_event().
* Merged "Update error status after reset_link()" patch into this patchset.
Changes since v3:
* Moved EDR related ACPI functions/definitions to pci-acpi.c
* Modified commit history in few patches to include spec reference.
* Added support to handle DPC triggered by NON_FATAL errors.
* Added edr_lock to protect PCI device receiving duplicate EDR notifications.
* Addressed Bjorn comments.
Changes since v2:
* Split EDR support patch into multiple patches.
* Addressed Bjorn comments.
Changes since v1:
* Rebased on top of v5.1-rc1
