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 >

From: LeoLiuoc <LeoLiu-oc@zhaoxin.com> According to the Section 18.3.2.4, 18.3.2.5 and 18.3.2.6 in ACPI SPEC r6.5, the register value form HEST PCI Express AER Structure should be written to relevant PCIe Device's AER Capabilities.So the purpose of the patch set is to extract register value from HEST PCI Express AER structures and program them into PCIe Device's AER registers. Refer to the ACPI SPEC r6.5 for the more detailed description. This patch is an effective supplement to _HPP/_HPX method when the Firmware does not support the _HPP/_HPX method and can be specially configured for the AER register of the specific device. --- v1->v2: - Move the definition of structure "hest_parse_aer_info" to file apei.h.
