From c7de829c796978e519984df2f1c8cfcf921a39a4 Mon Sep 17 00:00:00 2001 From: wdenk Date: Tue, 19 Nov 2002 11:04:11 +0000 Subject: [PATCH] * Patch by Thomas Frieden, 13 Nov 2002: Add code for AmigaOne board (preliminary merge to U-Boot, still WIP) * Patch by Jon Diekema, 12 Nov 2002: - Adding URL for IEEE OUI lookup - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED being defined. - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and root-on-nfs macros are designed to switch how the default boot method gets defined. --- CHANGELOG | 12 + CREDITS | 4 + MAINTAINERS | 5

This is useful if you wish to use a third party +debugging malloc library or perhaps a set of faster memory allocation +functions with the PM library, or any apps that use the PM library (such as +the MGL). Once you have registered your memory allocation routines, all +calls to PM_malloc, PM_calloc, PM_realloc and PM_free will be revectored to +your local memory allocation routines. + +This is also useful if you need to keep track of just how much physical +memory your program has been using. You can use the PM_availableMemory +function to find out how much physical memory is available when the program +starts, and then you can use your own local memory allocation routines to +keep track of how much memory has been used and freed. + +NOTE: This function should be called right at the start of your application, + before you initialise any other components or libraries. + +NOTE: Code compiled into Binary Portable DLL's and Drivers automatically + end up calling these functions via the BPD C runtime library. + +SEE ALSO: +PM_malloc, PM_calloc, PM_realloc, PM_free, PM_availableMemory +****************************************************************************/ +void PMAPI PM_useLocalMalloc( + void * (*malloc)(size_t size), + void * (*calloc)(size_t nelem,size_t size), + void * (*realloc)(void *ptr,size_t size), + void (*free)(void *p)) +{ + __PM_malloc = malloc; + __PM_calloc = calloc; + __PM_realloc = realloc; + __PM_free = free; +} + +/**************************************************************************** +DESCRIPTION: +Allocate a block of memory. + +HEADER: +pmapi.h + +PARAMETERS: +size - Size of block to allocate in bytes + +RETURNS: +Pointer to allocated block, or NULL if out of memory. + +REMARKS: +Allocates a block of memory of length size.

Tseng ET4000 W32P +This card wants to call the original system BIOS video routines. +It sets the int 0x42 vector to F000:F065, the entry point to the +system bios video routines. +CAVE: don't catch int 0x42 and use the vbios int 0x10 routines. +At early stage during initialization they call int 0x42. This +causes an infinite loop. + +2. ATi Mach64 Rage IIc AGP +This card does similar things like the Tseng ET4000 W32P. +However it doesn't have the problem with the ininite loop. + +3. Elsa Victory II-A16 AGP Banshee +This card is very clever: It knows it is an AGP card. Therefore +it knows it is behind a PCI-PCI bridge. It also knows that noone +else is behind this bridge. Therefore it start reprogramming the +bridge! For this it assumes the AGP bridge is on bus 1. + +4. Elsa Gloria Synergy 8 ViVo AGP PM2 +This card likes to see a complete interrupt vector table. If +we fill this table with 0 the VBIOS detects this and quits +initialization. + +5. Dimond Viper 330 AGP NVIDIA Riva 128. +This card has a similar problem like the Elsa Gloria. It wants +to read the system BIOS date at 0xffffd. + +6. Matrox Mystique PCI +This card reads the IO port 0x62. If it doesn't like what it sees +it loops forever. To keep the card happy put 0xfc into 0xffffe. +This location holds the system model id. 0xfc means IBM-AT. + One can make an interesting observation: this card likes to know +with whom it has to share the system. Therefore it accesses PCI +config space of all the other cards. It does this bypassing the +PCI BIOS by reading the PCI access ports directly. + +7. Matrox G100 AGP +This card has the same problem as the Mystique. + +Apperantly this works now. However not all combinations of cards are +checked, yet. + +Further notes: +the IO register 0x42-0x43 as well as 0x61-0x63 are of special interest +for many graphic cards. They should be emulated. +The so called "Industry Standard BIOS Entry Points" to int 0x42 (0xFF065) +and to int 0x1a (0xFFE6E) should be filled with useful code. This code +needs to return as if it was called as int. +The subvendor ID PCI registers might cause problems. On some chipsets +they are programmed in a non-obivous non-PCI conformant way. +V_Bioses are seen to modify the following int: +0x10 (default video), 0x1f(font table), 0x42(copy of default video), +0x43 (??), 0x6d (copy of default video - same as 0x10?) + +TODO: +Int 0x6d needs to be done. +All interrupts where there is no default industry standard entry point +should point to an unused location in the 0xF000 segmant (possibly +0xF0000). This way they could be trapped. A trap handler for +a. int 0x42 and int 0x1a needs to be implemented. +The default "industry entry point" for video and PCI (0xFFE6E) should +also be implemented. (any others?) They should either be routed to +int 0x42(0x6d?) (video) and 0x1A (PCI) or some other interrupts to +trap them. Mapping of system bios might not be a good idea. Maybe +the system bios area should just be filled with "hlt" to trap any +access there. +Handling of timer IO registers 0x42, 0x43 and IO registers 0x61, 0x62. + +Find documentation: +- on interrupt vector table +- on industry standard entry points to the system bios +- on IO registers 0x61 and 0x62 + + diff --git a/board/MAI/bios_emulator/scitech/src/v86bios/hexdump b/board/MAI/bios_emulator/scitech/src/v86bios/hexdump new file mode 100644 index 0000000000..4f359e5edd --- /dev/null +++ b/board/MAI/bios_emulator/scitech/src/v86bios/hexdump @@ -0,0 +1,3 @@ +"%06.6_ax " 16/1 "%02x " +" " 16/1 "%_p" +"\n" diff --git a/board/MAI/bios_emulator/scitech/src/v86bios/int.c b/board/MAI/bios_emulator/scitech/src/v86bios/int.c new file mode 100644 index 0000000000..40b17b1d70 --- /dev/null +++ b/board/MAI/bios_emulator/scitech/src/v86bios/int.c @@ -0,0 +1,238 @@ +/* + * Copyright 1999 Egbert Eich + * + * Permission to use, copy, modify, distribute, and sell this software and its + * documentation for any purpose is hereby granted without fee, provided that + * the above copyright notice appear in all copies and that both that + * copyright notice and this permission notice appear in supporting + * documentation, and that the name of the authors not be used in + * advertising or publicity pertaining to distribution of the software without + * specific, written prior permission.

The table which +* dispatches this is found in the files optab.[ch]. +* +* Each opcode proc has a comment preceeding it which gives it's table +* address. Several opcodes are missing (undefined) in the table. +* +* Each proc includes information for decoding (DECODE_PRINTF and +* DECODE_PRINTF2), debugging (TRACE_REGS, SINGLE_STEP), and misc +* functions (START_OF_INSTR, END_OF_INSTR). +* +* Many of the procedures are *VERY* similar in coding. This has +* allowed for a very large amount of code to be generated in a fairly +* short amount of time (i.e. cut, paste, and modify). The result is +* that much of the code below could have been folded into subroutines +* for a large reduction in size of this file. The downside would be +* that there would be a penalty in execution speed. The file could +* also have been *MUCH* larger by inlining certain functions which +* were called. This could have resulted even faster execution. The +* prime directive I used to decide whether to inline the code or to +* modularize it, was basically: 1) no unnecessary subroutine calls, +* 2) no routines more than about 200 lines in size, and 3) modularize +* any code that I might not get right the first time. The fetch_* +* subroutines fall into the latter category. The The decode_* fall +* into the second category. The coding of the "switch(mod){ .... }" +* in many of the subroutines below falls into the first category. +* Especially, the coding of {add,and,or,sub,...}_{byte,word} +* subroutines are an especially glaring case of the third guideline. +* Since so much of the code is cloned from other modules (compare +* opcode #00 to opcode #01), making the basic operations subroutine +* calls is especially important; otherwise mistakes in coding an +* "add" would represent a nightmare in maintenance. +* +****************************************************************************/ + +#include "x86emu/x86emui.h" + +/*----------------------------- Implementation ----------------------------*/ + +/**************************************************************************** +PARAMETERS: +op1 - Instruction op code + +REMARKS: +Handles illegal opcodes. +****************************************************************************/ +void x86emuOp_illegal_op( + u8 op1) +{ + START_OF_INSTR();
