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.)
Kind regards,
Niklas
