68060 SOFTWARE PACKAGE (Kernel version) SIMPLE TESTS

-----------------------------------------------------

The files itest.sa and ftest.sa contain simple tests to check

the state of the 68060ISP and 68060FPSP once they have been installed.

Release file format:

--------------------

The release files itest.sa and ftest.sa are essentially

hexadecimal images of the actual tests. This format is the

ONLY format that will be supported. The hex images were created

by assembling the source code and then converting the resulting

binary output images into ASCII text files. The hexadecimal

numbers are listed using the Motorola Assembly syntax assembler

directive "dc.l" (define constant longword). The files can be

converted to other assembly syntaxes by using any word processor

with a global search and replace function.

To assist in assembling and linking these modules with other modules,

the installer should add symbolic labels to the top of the files.

This will allow the calling routines to access the entry points

of these packages.

The source code itest.s and ftest.s have been included but only

for documentation purposes.

Release file structure:

-----------------------

(top of module)

        -----------------

        |               | - 128 byte-sized section

   (1)  |   Call-Out    | - 4 bytes per entry (user fills these in)

        |               |

        -----------------

        |               | - 8 bytes per entry

   (2)  | Entry Point   | - user does "bsr" or "jsr" to this address

        |               |

        -----------------

        |               | - code section

   (3)  ~               ~

        |               |

        -----------------

(bottom of module)

The first section of this module is the "Call-out" section. This section

is NOT INCLUDED in {i,f}test.sa (an example "Call-out" section is provided at

the end of this file). The purpose of this section is to allow the test

routines to reference external printing functions that must be provided

by the host operating system. This section MUST be exactly 128 bytes in

size. There are 32 fields, each 4 bytes in size. Each field corresponds

to a function required by the test packages (these functions and their

location are listed in "68060{ISP,FPSP}-TEST call-outs" below). Each field

entry should contain the address of the corresponding function RELATIVE to

the starting address of the "call-out" section. The "Call-out" section must

sit adjacent to the {i,f}test.sa image in memory. Since itest.sa and ftest.sa

are individual tests, they each require their own "Call-out" sections.

The second section, the "Entry-point" section, is used by external routines

to access the test routines. Since the {i,f}test.sa hex files contain

no symbol names, this section contains function entry points that are fixed

with respect to the top of the package. The currently defined entry-points

are listed in section "68060{ISP,FPSP}-TEST entry points" below. A calling

routine would simply execute a "bsr" or "jsr" that jumped to the selected

function entry-point.

For example, to run the 060ISP test, write a program that includes the

itest.sa data and execute something similar to:

        bsr     _060ISP_TEST+128+0

(_060ISP_TEST is the starting address of the "Call-out" section; the "Call-out"

section is 128 bytes long; and the 68060ISP test entry point is located

The third section is the code section. After entering through an "Entry-point",

the entry code jumps to the appropriate test code within the code section.

68060ISP-TEST Call-outs:

------------------------

0x0: _print_string()

0x4: _print_number()

68060FPSP-TEST Call-outs:

-------------------------

0x0: _print_string()

0x4: _print_number()

The test packages call _print_string() and _print_number()

as subroutines and expect the main program to print a string

or a number to a file or to the screen.

In "C"-like fashion, the test program calls:

        print_string("Test passed");

                or

        print_number(20);

For _print_string(), the test programs pass a longword address

of the string on the stack. For _print_number(), the test programs pass

a longword number to be printed.

For debugging purposes, after the main program performs a "print"

for a test package, it should flush the output so that it's not

buffered. In this way, if the test program crashes, at least the previous

statements printed will be seen.

68060ISP-TEST Entry-points:

---------------------------

0x0: integer test

68060FPSP-TEST Entry-points:

----------------------------

0x00: main fp test

0x08: FP unimplemented test

0x10: FP enabled snan/operr/ovfl/unfl/dz/inex

The floating-point unit test has 3 entry points which will require

3 different calls to the package if each of the three following tests

is desired:

main fp test: tests (1) unimp effective address exception

                    (2) unsupported data type exceptions

                    (3) non-maskable overflow/underflow exceptions

FP unimplemented: tests FP unimplemented exception. this one is

                  separate from the previous tests for systems that don't

                  want FP unimplemented instructions.

FP enabled: tests enabled snan/operr/ovfl/unfl/dz/inex.

            basically, it enables each of these exceptions and forces

            each using an implemented FP instruction. this process

            exercises _fpsp_{snan,operr,ovfl,unfl,dz,inex}() and

            _real_{snan,operr,ovfl,unfl,dz,inex}(). the test expects

            _real_XXXX() to do nothing except clear the exception

            and "rte". if a system's _real_XXXX() handler creates an

            alternate result, the test will print "failed" but this

            is acceptable.

Miscellaneous:

--------------

Again, itest.sa and ftest.sa are simple tests and do not thoroughly

test all 68060SP connections. For example, they do not test connections

to _real_access(), _real_trace(), _real_trap(), etc. because these

will be system-implemented several different ways and the test packages

must remain system independent.

Example test package set-up:

----------------------------

_print_str:

        .                       # provided by system

        rts

        .                       # provided by system

        rts

        .

        .

        bsr     _060FPSP_TEST+128+0

        .

        .

        rts

# beginning of "Call-out" section; provided by integrator.

# MUST be 128 bytes long.

        long    _print_num - _060FPSP_TEST

        space   120

# ftest.sa starts here; start of "Entry-point" section.

        long    0x60ff0000, 0x00018766

        long    0x60ff0000, 0x00023338
