   1 Driver for PCI Endpoint Test Function
   2
   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].
   6
   7 The "pci_endpoint_test" driver can be used to perform the following tests.
   8
   9 The 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         *) read data
  14         *) write data
  15         *) copy data
  16
  17 This misc driver creates /dev/pci-endpoint-test.<num> for every
  18 *pci_epf_test* function connected to the root complex and "ioctls"
  19 should be used to perform the above tests.

  21 ioctl
  22 -----
  23  PCITEST_BAR: Tests the BAR. The number of the BAR to be tested
  24               should be passed as argument.
  25  PCITEST_LEGACY_IRQ: Tests legacy IRQ
  26  PCITEST_MSI: Tests message signalled interrupts. The MSI number
  27               to be tested should be passed as argument.
  28  PCITEST_WRITE: Perform write tests. The size of the buffer should be passed
  29                 as argument.
  30  PCITEST_READ: Perform read tests. The size of the buffer should be passed
  31                as argument.
  32  PCITEST_COPY: Perform read tests. The size of the buffer should be passed
  33                as argument.
