docs: misc-devices/pci-endpoint-test.txt: convert to ReST 



- Use titles markups;
- Adjust identation;
- use literal markup;
- Use the proper notation for footnotes.

=====================================

Driver for PCI Endpoint Test Function

=====================================



This driver should be used as a host side driver if the root complex is

connected to a configurable PCI endpoint running ``pci_epf_test`` function

driver configured according to [1]_.



The "pci_endpoint_test" driver can be used to perform the following tests.



The PCI driver for the test device performs the following tests:



	#) verifying addresses programmed in BAR

	#) raise legacy IRQ

	#) raise MSI IRQ

	#) raise MSI-X IRQ

	#) read data

	#) write data

	#) copy data



This misc driver creates /dev/pci-endpoint-test.<num> for every

``pci_epf_test`` function connected to the root complex and "ioctls"

should be used to perform the above tests.



ioctl

-----



 PCITEST_BAR:

	      Tests the BAR. The number of the BAR to be tested

	      should be passed as argument.

 PCITEST_LEGACY_IRQ:

	      Tests legacy IRQ

 PCITEST_MSI:

	      Tests message signalled interrupts. The MSI number

	      to be tested should be passed as argument.

 PCITEST_MSIX:

	      Tests message signalled interrupts. The MSI-X number

	      to be tested should be passed as argument.

 PCITEST_SET_IRQTYPE:

	      Changes driver IRQ type configuration. The IRQ type

	      should be passed as argument (0: Legacy, 1:MSI, 2:MSI-X).

 PCITEST_GET_IRQTYPE:

	      Gets driver IRQ type configuration.

 PCITEST_WRITE:

	      Perform write tests. The size of the buffer should be passed

	      as argument.

 PCITEST_READ:

	      Perform read tests. The size of the buffer should be passed

	      as argument.

 PCITEST_COPY:

	      Perform read tests. The size of the buffer should be passed

	      as argument.
