    "content": "Hi,\n\nThe pci-epf-test / pci_endpoint_test doorbell path requires the endpoint\ncontroller (EPC) driver to support dynamic inbound mapping. Without it, the\nhost-side test can run anyway and fail in vain.\n\nThis series makes the doorbell test capability-aware by:\n  - Advertising dynamic inbound mapping support from pci-epf-test via a\n    new CAP_DYNAMIC_INBOUND_MAPPING bit.\n  - Returning -EOPNOTSUPP for PCITEST_DOORBELL when the endpoint does not\n    advertise this capability.\n  - Skipping the kselftest doorbell case when -EOPNOTSUPP is returned.\n\nThis small series is derived from Niklas's suggestion:\n  https://lore.kernel.org/linux-pci/aYte-7hTxb7kXNlQ@ryzen/\n\nThanks,\n\nKoichiro Den (3):\n  PCI: endpoint: pci-epf-test: Advertise dynamic inbound mapping support\n  misc: pci_endpoint_test: Gate doorbell test on dynamic inbound mapping\n  selftests: pci_endpoint: Skip doorbell test when unsupported\n\n drivers/misc/pci_endpoint_test.c                         | 4 ++++\n drivers/pci/endpoint/functions/pci-epf-test.c            | 4 ++++\n tools/testing/selftests/pci_endpoint/pci_endpoint_test.c | 2 ++\n 3 files changed, 10 insertions(+)"
