1Driver for PCI Endpoint Test Function
2
3This driver should be used as a host side driver if the root complex is
4connected to a configurable PCI endpoint running *pci_epf_test* function
5driver configured according to [1].
6
7The "pci_endpoint_test" driver can be used to perform the following tests.
8
9The PCI driver for the test device performs the following tests
10	*) verifying addresses programmed in BAR
11	*) raise legacy IRQ
12	*) raise MSI IRQ
13	*) raise MSI-X IRQ
14	*) read data
15	*) write data
16	*) copy data
17
18This misc driver creates /dev/pci-endpoint-test.<num> for every
19*pci_epf_test* function connected to the root complex and "ioctls"
20should be used to perform the above tests.

22ioctl
23-----
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
35		as argument.
36 PCITEST_READ: Perform read tests. The size of the buffer should be passed
37	       as argument.
38 PCITEST_COPY: Perform read tests. The size of the buffer should be passed
39	       as argument.
