Just noticed that this removes the ACPICA header dependency problem that Rafael pointed out. This also applies (with minor offsets) to v6.9-rc1, so it's not very stale. We're almost to the v6.9 final release, so when v6.10-rc1 is tagged, can you rebase to that and repost this? I assume you have a platform that uses this. It would be good to mention that in the commit log of patches 1 and 3 so we have some idea of where it's useful and where changes need to be tested. > LeoLiuoc (3): > ACPI/APEI: Add hest_parse_pcie_aer() > PCI: Add AER bits #defines for PCIe to PCI/PCI-X Bridge > PCI/ACPI: Add pci_acpi_program_hest_aer_params() > > drivers/acpi/apei/hest.c | 69 +++++++++++++++++++++++- > drivers/pci/pci-acpi.c | 98 +++++++++++++++++++++++++++++++++++ > drivers/pci/pci.h | 9 ++++ > drivers/pci/probe.c | 1 + > include/acpi/apei.h | 17 ++++++ > include/uapi/linux/pci_regs.h | 3 ++ > 6 files changed, 195 insertions(+), 2 deletions(-) > > -- > 2.34.1 >
