1 Driver for PCI Endpoint Test Function
3 This driver should be used as a host side driver if the root complex is
4 connected to a configurable PCI endpoint running *pci_epf_test* function
5 driver configured according to [1].
7 The "pci_endpoint_test" driver can be used to perform the following tests.
9 The PCI driver for the test device performs the following tests
10 *) verifying addresses programmed in BAR
18 This misc driver creates /dev/pci-endpoint-test.<num> for every
19 *pci_epf_test* function connected to the root complex and "ioctls"
20 should be used to perform the above tests.
24 PCITEST_BAR: Tests the BAR. The number of the BAR to be tested
25 should be passed as argument.
26 PCITEST_LEGACY_IRQ: Tests legacy IRQ
27 PCITEST_MSI: Tests message signalled interrupts. The MSI number
28 to be tested should be passed as argument.
29 PCITEST_MSIX: Tests message signalled interrupts. The MSI-X number
30 to be tested should be passed as argument.
31 PCITEST_SET_IRQTYPE: Changes driver IRQ type configuration. The IRQ type
32 should be passed as argument (0: Legacy, 1:MSI, 2:MSI-X).
33 PCITEST_GET_IRQTYPE: Gets driver IRQ type configuration.
34 PCITEST_WRITE: Perform write tests. The size of the buffer should be passed
36 PCITEST_READ: Perform read tests. The size of the buffer should be passed
38 PCITEST_COPY: Perform read tests. The size of the buffer should be passed
