Subject: Merge branch 'pci/aer'
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3c3ab37f4c03dc9c7c917ff3c1e71d6da81d3bd3;p=linux.git

Merge branch 'pci/aer'

  - Decode AER errors with names similar to "lspci" (Tyler Baicar)

  - Expose AER statistics in sysfs (Rajat Jain)

  - Clear AER status bits selectively based on the type of recovery (Oza
    Pawandeep)

  - Honor "pcie_ports=native" even if HEST sets FIRMWARE_FIRST (Alexandru
    Gagniuc)

  - Don't clear AER status bits if we're using the "Firmware-First"
    strategy where firmware owns the registers (Alexandru Gagniuc)

* pci/aer:
  PCI/AER: Don't clear AER bits if error handling is Firmware-First
  PCI/AER: Remove duplicate PCI_EXP_AER_FLAGS definition
  PCI/portdrv: Remove pcie_portdrv_err_handler.slot_reset
  PCI/AER: Clear device status bits during ERR_COR handling
  PCI/AER: Clear device status bits during ERR_FATAL and ERR_NONFATAL
  PCI/AER: Remove ERR_FATAL code from ERR_NONFATAL path
  PCI/AER: Factor out ERR_NONFATAL status bit clearing
  PCI/AER: Clear only ERR_NONFATAL bits during non-fatal recovery
  PCI/AER: Clear only ERR_FATAL status bits during fatal recovery
  PCI/AER: Honor "pcie_ports=native" even if HEST sets FIRMWARE_FIRST
  PCI/AER: Add sysfs attributes for rootport cumulative stats
  PCI/AER: Add sysfs attributes to provide AER stats and breakdown
  PCI/AER: Define aer_stats structure for AER capable devices
  PCI/AER: Move internal declarations to drivers/pci/pci.h
  PCI/AER: Adopt lspci names for AER error decoding
  PCI/AER: Expose internal API for obtaining AER information
