Hello all, For the PCITEST_WRITE, PCITEST_READ, and PCITEST_COPY test cases, tools/testing/selftests/pci_endpoint/pci_endpoint_test.c unconditionally uses MSIs, even for EPC drivers that do not support MSI. (E.g. an EPC could support only INTx, or only MSI-X.) Thus, improve tools/testing/selftests/pci_endpoint/pci_endpoint_test.c to use any supported IRQ type (by introducing a new IRQ type PCITEST_IRQ_TYPE_AUTO). Note that it is only the PCITEST_WRITE, PCITEST_READ, and PCITEST_COPY test cases that will use this new IRQ type. (PCITEST_MSI, PCITEST_MSIX, and PCITEST_LEGACY_IRQ actually test a specific IRQ type, so these test cases must still use a specific IRQ type.)
