Diagnostic Test Descriptions

	The diagnostic tests are divided into four groups:
	 Basic Functional Tests (Group A)
	 Memory Tests (Group B)
	 Block Tests (Group C)
	 Ethernet Traffic Tests (Group D).
	The diagnostic tests are described in Table 9.
	Table 9. Diagnostic Tests
	Test	Description
Number	Name
	Group A: Basic Functional Tests
A1	Register	Verifies that registers accessible through the
		PCI/PCI-E interface implement the expected
		read-only or read/write attributes by
		attempting to modify those registers.
A2	PCI Configuration	Checks the functionality of the PCI Base
		Address Register (BAR) by varying the
		amount of memory requested by the BAR and
		verifying that the BAR actually requests the
		correct amount of memory (without actually
		mapping the BAR into system memory). Refer
		to PCI or PCI-E specifications for details on
		the BAR and its addressing space.
A3	Interrupt	Generates a PCI interrupt and verifies that the
		system receives the interrupt and invokes the
		correct ISR. A negative test is also performed
		to verify that a masked interrupt does not
		invoke the ISR.
A5	MSI	Verifies that a Message Signaled Interrupt
		(MSI) causes an MSI message to be DMA'd to
		host memory. A negative test is also
		performed to verify that when an MSI is
		masked, it does not write an MSI message to
		host memory.
A6	Memory BIST	Invokes the internal chip Built-In Self Test
		(BIST) command to test internal memory.
