From 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 16 Apr 2005 15:20:36 -0700 Subject: Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

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 +0 bytes from the top of the "Entry-point" section.) + +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 + +_print_num: + . # provided by system + rts + + . + . + bsr _060FPSP_TEST+128+0 + . + . + rts + +# beginning of "Call-out" section; provided by integrator. +# MUST be 128 bytes long. +_060FPSP_TEST: + long _print_str - _060FPSP_TEST + long _print_num - _060FPSP_TEST + space 120 + +# ftest.sa starts here; start of "Entry-point" section. + long 0x60ff0000, 0x00002346 + long 0x60ff0000, 0x00018766 + long 0x60ff0000, 0x00023338 + long 0x24377299, 0xab2643ea + . + . + . -- cgit v1.2.3-70-g09d2
