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.

Vector numbers for the latter can + * be allocated by atari_register_vme_int(). + * + * Each interrupt can be of three types: + * + * - SLOW: The handler runs with all interrupts enabled, except the one it + * was called by (to avoid reentering). This should be the usual method. + * But it is currently possible only for MFP ints, since only the MFP + * offers an easy way to mask interrupts. + * + * - FAST: The handler runs with all interrupts disabled. This should be used + * only for really fast handlers, that just do actions immediately + * necessary, and let the rest do a bottom half or task queue. + * + * - PRIORITIZED: The handler can be interrupted by higher-level ints + * (greater IPL, no MFP priorities!). This is the method of choice for ints + * which should be slow, but are not from a MFP. + * + * The feature of more than one handler for one int source is still there, but + * only applicable if all handers are of the same type. To not slow down + * processing of ints with only one handler by the chaining feature, the list + * calling function atari_call_irq_list() is only plugged in at the time the + * second handler is registered. + * + * Implementation notes: For fast-as-possible int handling, there are separate + * entry points for each type (slow/fast/prio). The assembler handler calls + * the irq directly in the usual case, no C wrapper is involved. In case of + * multiple handlers, atari_call_irq_list() is registered as handler and calls + * in turn the real irq's. To ease access from assembler level to the irq + * function pointer and accompanying data, these two are stored in a separate + * array, irq_handler[]. The rest of data (type, name) are put into a second + * array, irq_param, that is accessed from C only. For each slow interrupt (32 + * in all) there are separate handler functions, which makes it possible to + * hard-code the MFP register address and value, are necessary to mask the + * int. If there'd be only one generic function, lots of calculations would be + * needed to determine MFP register and int mask from the vector number :-( + * + * Furthermore, slow ints may not lower the IPL below its previous value + * (before the int happened). This is needed so that an int of class PRIO, on + * that this int may be stacked, cannot be reentered. This feature is + * implemented as follows: If the stack frame format is 1 (throwaway), the int + * is not stacked, and the IPL is anded with 0xfbff, resulting in a new level + * 2, which still blocks the HSYNC, but no interrupts of interest. If the + * frame format is 0, the int is nested, and the old IPL value can be found in + * the sr copy in the frame. + */ + + +#define NUM_INT_SOURCES (8 + NUM_ATARI_SOURCES) + +typedef void (*asm_irq_handler)(void); + +struct irqhandler { + irqreturn_t (*handler)(int, void *, struct pt_regs *); + void *dev_id; +}; + +struct irqparam { + unsigned long flags; + const char *devname; +}; + +/* + * Array with irq's and their parameter data.

Such drivers have to use __get_dma_pages(), which unfortunately + * often isn't very successful in allocating more than 1 page :-( [1] The net + * result was that most of the time you couldn't insmod such modules (ataflop, + * ACSI, SCSI on Falcon, Atari internal framebuffer, not to speak of acsi_slm, + * which needs a 1 MB buffer... :-). + * + * To overcome this limitation, ST-RAM can now be turned into a very + * high-speed swap space. If a request for an ST-RAM buffer comes, the kernel + * now tries to unswap some pages on that swap device to make some free (and + * contiguous) space. This works much better in comparison to + * __get_dma_pages(), since used swap pages can be selectively freed by either + * moving them to somewhere else in swap space, or by reading them back into + * system memory. Ok, there operation of unswapping isn't really cheap (for + * each page, one has to go through the page tables of all processes), but it + * doesn't happen that often (only when allocation ST-RAM, i.e. when loading a + * module that needs ST-RAM). But it at least makes it possible to load such + * modules! + * + * It could also be that overall system performance increases a bit due to + * ST-RAM swapping, since slow ST-RAM isn't used anymore for holding data or + * executing code in. It's then just a (very fast, compared to disk) back + * storage for not-so-often needed data. (But this effect must be compared + * with the loss of total memory...) Don't know if the effect is already + * visible on a TT, where the speed difference between ST- and TT-RAM isn't + * that dramatic, but it should on machines where TT-RAM is really much faster + * (e.g. Afterburner). + * + * [1]: __get_free_pages() does a fine job if you only want one page, but if + * you want more (contiguous) pages, it can give you such a block only if + * there's already a free one. The algorithm can't try to free buffers or swap + * out something in order to make more free space, since all that page-freeing + * mechanisms work "target-less", i.e. they just free something, but not in a + * specific place.

'get_op' +| determines the opclass (0, 2, or 3) and branches to the +| opclass handler routine. See 68881/2 User's Manual table 4-11 +| for a description of the opclasses. +| +| For UNSUPPORTED data/format (exception vector 55) and for +| UNIMPLEMENTED instructions (exception vector 11) the following +| applies: +| +| - For unnormalized numbers (opclass 0, 2, or 3) the +| number(s) is normalized and the operand type tag is updated. +| +| - For a packed number (opclass 2) the number is unpacked and the +| operand type tag is updated. +| +| - For denormalized numbers (opclass 0 or 2) the number(s) is not +| changed but passed to the next module. The next module for +| unimp is do_func, the next module for unsupp is res_func. +| +| For UNSUPPORTED data/format (exception vector 55) only the +| following applies: +| +| - If there is a move out with a packed number (opclass 3) the +| number is packed and written to user memory. For the other +| opclasses the number(s) are written back to the fsave stack +| and the instruction is then restored back into the '040. The +| '040 is then able to complete the instruction. +| +| For example: +| fadd.x fpm,fpn where the fpm contains an unnormalized number. +| The '040 takes an unsupported data trap and gets to this +| routine. The number is normalized, put back on the stack and +| then an frestore is done to restore the instruction back into +| the '040. The '040 then re-executes the fadd.x fpm,fpn with +| a normalized number in the source and the instruction is +| successful. +| +| Next consider if in the process of normalizing the un- +| normalized number it becomes a denormalized number. The +| routine which converts the unnorm to a norm (called mk_norm) +| detects this and tags the number as a denorm. The routine +| res_func sees the denorm tag and converts the denorm to a +| norm. The instruction is then restored back into the '040 +| which re_executes the instruction. +| +| +| Copyright (C) Motorola, Inc. 1990 +| All Rights Reserved +| +| THIS IS UNPUBLISHED PROPRIETARY SOURCE

Exit. +| Notes: The various arrangements of the expressions give accurate +| evaluations. +| +| Step 7. exp(X)-1 for |X| < 1/4. +| 7.1 If |X| >= 2^(-65), go to Step 9. +| 7.2 Go to Step 8. +| +| Step 8.

Exit. +| 8.3 X := X * 2^(140). +| 8.4 Restore FPCR; ans := ans - 2^(-16382). +| Return ans := ans*2^(140). Exit +| Notes: The idea is to return "X - tiny" under the user +| precision and rounding modes. To avoid unnecessary +| inefficiency, we stay away from denormalized numbers the +| best we can. For |X| >= 2^(-16312), the straightforward +| 8.2 generates the inexact exception as the case warrants. +| +| Step 9. Calculate exp(X)-1, |X| < 1/4, by a polynomial +| p = X + X*X*(B1 + X*(B2 + ... + X*B12)) +| Notes: a) In order to reduce memory access, the coefficients are +| made as "short" as possible: B1 (which is 1/2), B9 to B12 +| are single precision; B3 to B8 are double precision; and +| B2 is double extended. +| b) Even with the restriction above, +| |p - (exp(X)-1)| < |X| 2^(-70.6) +| for all |X| <= 0.251. +| Note that 0.251 is slightly bigger than 1/4. +| c) To fully preserve accuracy, the polynomial is computed +| as X + ( S*B1 + Q ) where S = X*X and +| Q = X*S*(B2 + X*(B3 + ... + X*B12)) +| d) To fully utilize the pipeline, Q is separated into +| two independent pieces of roughly equal complexity +| Q = [ X*S*(B2 + S*(B4 + ... + S*B12)) ] + +| [ S*S*(B3 + S*(B5 + ... + S*B11)) ] +| +| Step 10. Calculate exp(X)-1 for |X| >= 70 log 2. +| 10.1 If X >= 70log2 , exp(X) - 1 = exp(X) for all practical +| purposes. Therefore, go to Step 1 of setox. +| 10.2 If X <= -70log2, exp(X) - 1 = -1 for all practical purposes. +| ans := -1 +| Restore user FPCR +| Return ans := ans + 2^(-126). Exit. +| Notes: 10.2 will always create an inexact and return -1 + tiny +| in the user rounding precision and mode. +| +| + +| Copyright (C) Motorola, Inc. 1990 +| All Rights Reserved +| +| THIS IS

This has been corrected. + +4) Beta B.2 version had the following erratum: + + Scenario: + --------- + If {i,d}mem_{read,write}_{byte,word,long}() returns + a failing value to the 68060SP, the package ignores + this return value and continues with program execution + as if it never received a failing value. + + Effect: + ------- + For example, if a user executed "fsin.x ADDR,fp0" where + ADDR should cause a "segmentation violation", the memory read + requested by the package should return a failing value + to the package. Since the package currently ignores this + return value, the user program will continue to the + next instruction, and the result created in fp0 will be + undefined. + + Fix: + ---- + This has been fixed in the current release. + + Notes: + ------ + Upon receiving a non-zero (failing) return value from + a {i,d}mem_{read,write}_{byte,word,long}() "call-out", + the package creates a 16-byte access error stack frame + from the current exception stack frame and exits + through the "call-out" _real_access().

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 + . + . + . diff --git a/arch/m68k/ifpsp060/fplsp.doc b/arch/m68k/ifpsp060/fplsp.doc new file mode 100644 index 000000000000..fb637c436762 --- /dev/null +++ b/arch/m68k/ifpsp060/fplsp.doc @@ -0,0 +1,231 @@ +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +MOTOROLA MICROPROCESSOR & MEMORY TECHNOLOGY GROUP +M68000 Hi-Performance Microprocessor Division +M68060 Software Package +Production Release P1.00 -- October 10, 1994 + +M68060 Software Package Copyright © 1993, 1994 Motorola Inc.

The routines +included in this module can be used to emulate the +FP instructions not implemented in 68060 hardware. These +instructions normally take exception vector #11 +"FP Unimplemented Instruction". + +By re-compiling a program that uses these instructions, and +making subroutine calls in place of the unimplemented +instructions, a program can avoid the overhead associated +with taking the exception. + +Release file format: +-------------------- +The file fplsp.sa is essentially a hexadecimal image of the +release package. This is the ONLY format which will be supported. +The hex image was created by assembling the source code and +then converting the resulting binary output image into an +ASCII text file. The hexadecimal numbers are listed +using the Motorola Assembly Syntax assembler directive "dc.l" +(define constant longword). The file 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 this module with other modules, +the installer should add a symbolic label to the top of the file. +This will allow calling routines to access the entry points +of this package. + +The source code fplsp.s has also been included but only for +documentation purposes. + +Release file structure: +----------------------- +The file fplsp.sa contains an "Entry-Point" section and a +code section. The FPLSP has no "Call-Out" section. The first section +is the "Entry-Point" section. In order to access a function in the +package, a program must "bsr" or "jsr" to the location listed +below in "68060FPLSP entry points" that corresponds to the desired +function. A branch instruction located at the selected entry point +within the package will then enter the correct emulation code routine. + +The entry point addresses at the beginning of the package will remain +fixed so that a program calling the routines will not have to be +re-compiled with every new 68060FPLSP release. + +There are 3 entry-points for each instruction type: single precision, +double precision, and extended precision. + +As an example, the "fsin" library instruction can be passed an +extended precision operand if program executes: + +# fsin.x fp0 + + fmovm.x &0x01,-(%sp) # pass operand on stack + bsr.l _060FPLSP_TOP+0x1a8 # branch to fsin routine + add.l &0xc,%sp # clear operand from stack + +Upon return, fp0 holds the correct result. The FPSR is +set correctly. The FPCR is unchanged. The FPIAR is undefined. + +Another example. This time, a dyadic operation: + +# frem.s %fp1,%fp0 + + fmov.s %fp1,-(%sp) # pass src operand + fmov.s %fp0,-(%sp) # pass dst operand + bsr.l _060FPLSP_TOP+0x168 # branch to frem routine + addq.l &0x8,%sp # clear operands from stack + +Again, the result is returned in fp0. Note that BOTH operands +are passed in single precision format. + +Exception reporting: +-------------------- +The package takes exceptions according to the FPCR value upon subroutine +entry. If an exception should be reported, then the package forces +this exception using implemented floating-point instructions. +For example, if the instruction being emulated should cause a +floating-point Operand Error exception, then the library routine +executes an FMUL of a zero and an infinity to force the OPERR +exception. Although the FPIAR will be undefined for the enabled +Operand Error exception handler, the user will at least be able +to record that the event occurred. + +Miscellaneous: +-------------- +The package does not attempt to correctly emulate instructions +with Signalling NAN inputs. Use of SNANs should be avoided with +this package. + +The fabs/fadd/fdiv/fint/fintrz/fmul/fneg/fsqrt/fsub entry points +are provided for the convenience of older compilers that make +subroutine calls for all fp instructions. The code does NOT emulate +the instruction but rather simply executes it. + +68060FPLSP entry points: +------------------------ +_060FPLSP_TOP: +0x000: _060LSP__facoss_ +0x008: _060LSP__facosd_

This package is essentially a set of exception handlers +that can be integrated into an operating system. +These exception handlers emulate Unimplemented FP instructions, +instructions using unimplemented data types, and instructions +using unimplemented addressing modes. In addition, this package +includes exception handlers to provide full IEEE-754 compliant +exception handling. + +Release file format: +-------------------- +The file fpsp.sa is essentially a hexadecimal image of the +release package. This is the ONLY format which will be supported. +The hex image was created by assembling the source code and +then converting the resulting binary output image into an +ASCII text file. The hexadecimal numbers are listed +using the Motorola Assembly Syntax assembler directive "dc.l" +(define constant longword). The file 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 this module with other modules, +the installer should add a symbolic label to the top of the file. +This will allow calling routines to access the entry points +of this package. + +The source code fpsp.s has also 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) + | | - example routines in fskeleton.s + ----------------- + | | - 8 bytes per entry + (2) | Entry Point | - user does "bra" or "jmp" 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 fpsp.sa (an example "Call-out" section is provided at +the end of the file fskeleton.s). The purpose of this section is to allow +the FPSP routines to reference external 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 FPSP (these functions and their location are +listed in "68060FPSP 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 +fpsp.sa image in memory. + +The second section, the "Entry-point" section, is used by external routines +to access the functions within the FPSP. Since the fpsp.sa hex file contains +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 FPSP entry points" below. A calling routine +would simply execute a "bra" or "jmp" that jumped to the selected function +entry-point. + +For example, if the 68060 hardware took a "Line-F Emulator" exception +(vector #11), the operating system should execute something similar to: + + bra _060FPSP_TOP+128+48 + +(_060FPSP_TOP is the starting address of the "Call-out" section; the "Call-out" +section is 128 bytes long; and the F-Line FPSP handler entry point is located +48 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 emulation code within the code section. + +68060FPSP call-outs: (details in fskeleton.s) +-------------------- +0x000:

Routines included in this +module can be used to emulate 64-bit divide and multiply, +and the "cmp2" instruction. These instructions are not +implemented in hardware on the 68060 and normally take +exception vector #61 "Unimplemented Integer Instruction". + +By re-compiling a program that uses these instructions, and +making subroutine calls in place of the unimplemented +instructions, a program can avoid the overhead associated with +taking the exception. + +Release file format: +-------------------- +The file ilsp.sa is essentially a hexadecimal image of the +release package. This is the ONLY format which will be supported. +The hex image was created by assembling the source code and +then converting the resulting binary output image into an +ASCII text file. The hexadecimal numbers are listed +using the Motorola Assembly Syntax assembler directive "dc.l" +(define constant longword). The file 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 this module with other modules, +the installer should add a symbolic label to the top of the file. +This will allow calling routines to access the entry points +of this package. + +The source code ilsp.s has also been included but only for +documentation purposes. + +Release file structure: +----------------------- +The file ilsp.sa contains an "Entry-Point" section and a +code section. The ILSP has no "Call-Out" section. The first section +is the "Entry-Point" section. In order to access a function in the +package, a program must "bsr" or "jsr" to the location listed +below in "68060ILSP Entry Points" that corresponds to the desired +function. A branch instruction located at the selected entry point +within the package will then enter the correct emulation code routine. + +The entry point addresses at the beginning of the package will remain +fixed so that a program calling the routines will not have to be +re-compiled with every new 68060ILSP release. + +For example, to use a 64-bit multiply instruction, +do a "bsr" or "jsr" to the entry point defined by +the 060ILSP entry table. A compiler generated code sequence +for unsigned multiply could look like: + +# mulu.l ,Dh:Dl +# mulu.l _multiplier,%d1:%d0 + + subq.l &0x8,%sp # make room for result on stack + pea (%sp) # pass: result addr on stack + mov.l %d0,-(%sp) # pass: multiplicand on stack + mov.l _multiplier,-(%sp) # pass: multiplier on stack + bsr.l _060LISP_TOP+0x18 # branch to multiply routine + add.l &0xc,%sp # clear arguments from stack + mov.l (%sp)+,%d1 # load result[63:32] + mov.l (%sp)+,%d0 # load result[31:0] + +For a divide: + +# divu.l ,Dr:Dq +# divu.l _divisor,%d1:%d0 + + subq.l &0x8,%sp # make room for result on stack + pea (%sp) # pass: result addr on stack + mov.l %d0,-(%sp) # pass: dividend hi on stack + mov.l %d1,-(%sp) # pass: dividend hi on stack + mov.l _divisor,-(%sp) # pass: divisor on stack + bsr.l _060LISP_TOP+0x08 # branch to divide routine + add.l &0xc,%sp # clear arguments from stack + mov.l (%sp)+,%d1 # load remainder + mov.l (%sp)+,%d0 # load quotient + +The library routines also return the correct condition code +register value. If this is important, then the caller of the library +routine must make sure that the value isn't lost while popping +other items off of the stack. + +An example of using the "cmp2" instruction is as follows: + +# cmp2.l ,Rn +# cmp2.l _bounds,%d0 + + pea _bounds # pass ptr to bounds + mov.l %d0,-(%sp) # pass Rn + bsr.l _060LSP_TOP_+0x48 # branch to "cmp2" routine + mov.w %cc,_tmp # save off condition codes + addq.l &0x8,%sp # clear arguments from stack + +Exception reporting: +-------------------- +If the instruction being emulated is a divide and the source +operand is a zero, then the library routine, as its last +instruction, executes an implemented divide using a zero +source operand so that an "Integer Divide-by-Zero" exception +will be taken. Although the exception stack frame will not +point to the correct instruction, the user will at least be able +to record that such an event occurred if desired. + +68060ILSP entry points:

The +isp.sa provides full emulation support for these instructions. + +The unimplemented integer instructions are: + 64-bit divide + 64-bit multiply + movep + cmp2 + chk2 + cas (w/ a misaligned effective address) + cas2 + +Release file format: +-------------------- +The file isp.sa is essentially a hexadecimal image of the +release package. This is the ONLY format which will be supported. +The hex image was created by assembling the source code and +then converting the resulting binary output image into an +ASCII text file. The hexadecimal numbers are listed +using the Motorola Assembly Syntax assembler directive "dc.l" +(define constant longword). The file 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 this module with other modules, +the installer should add a symbolic label to the top of the file. +This will allow calling routines to access the entry points +of this package. + +The source code isp.s has also 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) + | | - example routines in iskeleton.s + ----------------- + | | - 8 bytes per entry + (2) | Entry Point | - user does a "bra" or "jmp" 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 isp.sa (an example "Call-out" section is provided at +the end of the file iskeleton.s). The purpose of this section is to allow +the ISP routines to reference external 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 ISP (these functions and their location are +listed in "68060ISP 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 +isp.sa image in memory. + +The second section, the "Entry-point" section, is used by external routines +to access the functions within the ISP. Since the isp.sa hex file contains +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 entry points" below. A calling routine +would simply execute a "bra" or "jmp" that jumped to the selected function +entry-point. + +For example, if the 68060 hardware took a "Unimplemented Integer Instruction" +exception (vector #61), the operating system should execute something +similar to: + + bra _060ISP_TOP+128+0 + +(_060ISP_TOP is the starting address of the "Call-out" section; the "Call-out" +section is 128 bytes long; and the Unimplemented Integer ISP handler entry +point is located 0 bytes from the top of the "Entry-point" section.) + +The third section is the code section.

When the +060ISP is installed properly, these instructions will enter through the +_060_isp_unimp() entry point of the ISP. + +After the 060ISP decodes the instruction type and fetches the appropriate +data registers, and BEFORE the actual emulated transfers occur, the +package calls either the "Call-out" _060_real_cas() or _060_real_cas2(). +If the emulation code provided by the 060ISP is sufficient for the +host system (see isp.s source code), then these "Call-out"s should be +made, by the system integrator, to point directly back into the package +through the "Entry-point"s _060_isp_cas() or _060_isp_cas2(). + +One other necessary action by the integrator is to supply the routines +_060_real_lock_page() and _060_real_unlock_page(). These functions are +defined further in iskeleton.s and the 68060 Software Package Specification. + +If the "core" emulation routines of either "cas" or "cas2" perform some +actions which are too system-specific, then the system integrator must +supply new emulation code. This new emulation code should reside within +the functions _060_real_cas() or _060_real_cas2(). When this new emulation +code has completed, then it should re-enter the 060ISP package through the +"Entry-point" _060_isp_cas_finish() or _060_isp_cas2_finish(). +To see what the register state is upon entering _060_real_cas() or +_060_real_cas2() and what it should be upon return to the package through +_060_isp_cas_finish() or _060_isp_cas2_finish(), please refer to the +source code in isp.s.

The values of log(F) are # +# calculated beforehand and stored in the program. # +# # +# lognp1: # +# Step 1: If |X| < 1/16, approximate log(1+X) by an odd # +# polynomial in u where u = 2X/(2+X). Otherwise, move on # +# to Step 2. # +# # +# Step 2: Let 1+X = 2**k * Y, where 1 <= Y < 2. Define F as done # +# in Step 2 of the algorithm for LOGN and compute # +# log(1+X) as k*log(2) + log(F) + poly where poly # +# approximates log(1+u), u = (Y-F)/F. # +# # +# Implementation Notes: # +# Note 1. There are 64 different possible values for F, thus 64 # +# log(F)'s need to be tabulated. Moreover, the values of # +# 1/F are also tabulated so that the division in (Y-F)/F # +# can be performed by a multiplication. # +# # +# Note 2. In Step 2 of lognp1, in order to preserved accuracy, # +# the value Y-F has to be calculated carefully when # +# 1/2 <= X < 3/2. # +# # +# Note 3. To fully exploit the pipeline, polynomials are usually # +# separated into two parts evaluated independently before # +# being added up. # +# #

These can be either opclass 0,2 or 3 # +# instructions, and (2) PACKED unimplemented data format instructions # +# also of opclasses 0,2, or 3. # +# For UNNORM/DENORM opclass 0 and 2, the handler fetches the src # +# operand from the fsave state frame and the dst operand (if dyadic) # +# from the FP register file. The instruction is then emulated by # +# choosing an emulation routine from a table of routines indexed by # +# instruction type. Once the instruction has been emulated and result # +# saved, then we check to see if any enabled exceptions resulted from # +# instruction emulation. If none, then we exit through the "callout" # +# _fpsp_done(). If there is an enabled FP exception, then we insert # +# this exception into the FPU in the fsave state frame and then exit # +# through _fpsp_done(). # +# PACKED opclass 0 and 2 is similar in how the instruction is # +# emulated and exceptions handled. The differences occur in how the # +# handler loads the packed op (by calling get_packed() routine) and # +# by the fact that a Trace exception could be pending for PACKED ops. # +# If a Trace exception is pending, then the current exception stack # +# frame is changed to a Trace exception stack frame and an exit is # +# made through _real_trace(). # +# For UNNORM/DENORM opclass 3, the actual move out to memory is # +# performed by calling the routine fout(). If no exception should occur # +# as the result of emulation, then an exit either occurs through # +# _fpsp_done() or through _real_trace() if a Trace exception is pending # +# (a Trace stack frame must be created here, too). If an FP exception # +# should occur, then we must create an exception stack frame of that # +# type and jump to either _real_snan(), _real_operr(), _real_inex(), # +# _real_unfl(), or _real_ovfl() as appropriate.

+# This exception handles 3 types of operations: # +# (1) FP Instructions using extended precision or packed immediate # +# addressing mode. # +# (2) The "fmovm.x" instruction w/ dynamic register specification. # +# (3) The "fmovm.l" instruction w/ 2 or 3 control registers. # +# # +# For immediate data operations, the data is read in w/ a # +# _mem_read() "callout", converted to FP binary (if packed), and used # +# as the source operand to the instruction specified by the instruction # +# word. If no FP exception should be reported ads a result of the # +# emulation, then the result is stored to the destination register and # +# the handler exits through _fpsp_done(). If an enabled exc has been # +# signalled as a result of emulation, then an fsave state frame # +# corresponding to the FP exception type must be entered into the 060 # +# FPU before exiting. In either the enabled or disabled cases, we # +# must also check if a Trace exception is pending, in which case, we # +# must create a Trace exception stack frame from the current exception # +# stack frame. If no Trace is pending, we simply exit through # +# _fpsp_done(). # +# For "fmovm.x", call the routine fmovm_dynamic() which will # +# decode and emulate the instruction. No FP exceptions can be pending # +# as a result of this operation emulation. A Trace exception can be # +# pending, though, which means the current stack frame must be changed # +# to a Trace stack frame and an exit made through _real_trace(). # +# For the case of "fmovm.x Dn,-(a7)", where the offending instruction # +# was executed from supervisor mode, this handler must store the FP # +# register file values to the system stack by itself since # +# fmovm_dynamic() can't handle this. A normal exit is made through # +# fpsp_done(). # +# For "fmovm.l", fmovm_ctrl() is used to emulate the instruction. # +# Again, a Trace exception may be pending and an exit made through # +# _real_trace(). Else, a normal exit is made through _fpsp_done(). # +# # +# Before any of the above is attempted, it must be checked to # +# see if the FPU is disabled. Since the "Unimp " exception is taken # +# before the "FPU disabled" exception, but the "FPU disabled" exception # +# has higher priority, we check the disabled bit in the PCR. If set, # +# then we must create an 8 word "FPU disabled" exception stack frame # +# from the current 4 word exception stack frame. This includes # +# reproducing the effective address of the instruction to put on the # +# new stack frame. # +# # +# In the process of all emulation work, if a _mem_read() # +# "callout" returns a failing result indicating an access error, then # +# we must create an access error stack frame from the current stack # +# frame. This information includes a faulting address and a fault- # +# status-longword.
