DOING A HARDWARE TRACE IN WINE
|
||||
------------------------------
|
||||
|
||||
The primary reason to do this is to reverse engineer a hardware device
|
||||
for which you don't have documentation, but can get to work under Wine.
|
||||
|
||||
This lot is aimed at parallel port devices, and in particular parallel port
|
||||
scanners which are now so cheap they are virtually being given away. The
|
||||
problem is that few manufactures will release any programming information which
|
||||
prevents drivers being written for Sane, and the traditional technique of using
|
||||
DOSemu to produce the traces does not work as the scanners invariably only have
|
||||
drivers for Windows.
|
||||
|
||||
Please note that I have not been able to get my scanner working properly (a
|
||||
UMAX Astra 600P), but a couple of people have reported success with at least
|
||||
the Artec AS6e scanner. I am not in the process of developing any driver nor do
|
||||
I intend to, so don't bug me about it. My time is now spent writting programs
|
||||
to set things like battery save options under Linux on Toshiba laptops, ans as
|
||||
such I don't have any spare time for writting a driver for a parallel port
|
||||
scanner etc.
|
||||
|
||||
Presuming that you have compiled and installed wine the first thing to do is is
|
||||
to enable direct hardware access to your parallel port. To do this edit
|
||||
wine.conf (usually in /usr/local/etc) and in the ports section add the
|
||||
following two lines
|
||||
|
||||
read=0x378,0x379,0x37a,0x37c,0x77a
|
||||
write=0x378,x379,0x37a,0x37c,0x77a
|
||||
|
||||
This adds the necessary access required for SPP/PS2/EPP/ECP parallel port on
|
||||
LPT1. You will need to adjust these number accordingly if your parallel port is
|
||||
on LPT2 or LPT0.
|
||||
|
||||
When starting wine use the following command line, where XXXX is the program
|
||||
you need to run in order to access your scanner, and YYYY is the file your
|
||||
trace will be stored in:
|
||||
|
||||
wine -debugmsg +io XXXX 2> >(sed 's/^[^:]*:io:[^ ]* //' > YYYY)
|
||||
|
||||
You will need large amounts of hard disk space (read hundreds of megabytes if
|
||||
you do a full page scan), and for reasonable performance a really fast
|
||||
processor and lots of RAM.
|
||||
|
||||
You might well find the log compression program that David Campbell
|
||||
<campbell@torque.net> wrote helpfull in reducing the size of the log files.
|
||||
This can be obtained by the following command:
|
||||
|
||||
sh ioport-trace-hints
|
||||
|
||||
This should extract shrink.c (which is located at the end of this file. Compile
|
||||
the log compression program by:
|
||||
|
||||
cc shrink.c -o shrink
|
||||
|
||||
Use the shrink program to reduce the physical size of the raw log as follows:
|
||||
|
||||
cat log | shrink > log2
|
||||
|
||||
The trace has the basic form of
|
||||
|
||||
XXXX > YY @ ZZZZ:ZZZZ
|
||||
|
||||
where XXXX is the port in hexidecimal being accessed, YY is the data written
|
||||
(or read) from the port, and ZZZZ:ZZZZ is the address in memory of the
|
||||
instruction that accessed the port. The direction of the arrow indicates
|
||||
whether the data was written or read from the port.
|
||||
|
||||
> data was written to the port
|
||||
< data was read from the port
|
||||
|
||||
|
||||
My basic tip for interperating these logs is to pay close attention to the
|
||||
addresses of the IO instructions. There grouping and sometimes proximity should
|
||||
reveal the presence of subroutines in the driver. By studying the different
|
||||
versions you should be able to work them out. For example consider the
|
||||
following section of trace from my UMAX Astra 600P
|
||||
|
||||
0x378 > 55 @ 0297:01ec
|
||||
0x37a > 05 @ 0297:01f5
|
||||
0x379 < 8f @ 0297:01fa
|
||||
0x37a > 04 @ 0297:0211
|
||||
0x378 > aa @ 0297:01ec
|
||||
0x37a > 05 @ 0297:01f5
|
||||
0x379 < 8f @ 0297:01fa
|
||||
0x37a > 04 @ 0297:0211
|
||||
0x378 > 00 @ 0297:01ec
|
||||
0x37a > 05 @ 0297:01f5
|
||||
0x379 < 8f @ 0297:01fa
|
||||
0x37a > 04 @ 0297:0211
|
||||
0x378 > 00 @ 0297:01ec
|
||||
0x37a > 05 @ 0297:01f5
|
||||
0x379 < 8f @ 0297:01fa
|
||||
0x37a > 04 @ 0297:0211
|
||||
0x378 > 00 @ 0297:01ec
|
||||
0x37a > 05 @ 0297:01f5
|
||||
0x379 < 8f @ 0297:01fa
|
||||
0x37a > 04 @ 0297:0211
|
||||
0x378 > 00 @ 0297:01ec
|
||||
0x37a > 05 @ 0297:01f5
|
||||
0x379 < 8f @ 0297:01fa
|
||||
0x37a > 04 @ 0297:0211
|
||||
|
||||
As you can see their is a repeating structure starting at address 0297:01ec
|
||||
that consists of four io access on the parallel port. Looking at it the first
|
||||
io access writes a changing byte to the data port the second always writes the
|
||||
byte 0x05 to the control port, then a value which always seems to 0x8f is read
|
||||
from the status port at which point a byte 0x04 is written to the control port.
|
||||
By studying this and other sections of the trace we can write a C routine that
|
||||
emulates this, shown below with some macros to make reading/writing on the
|
||||
parallel port easier to read.
|
||||
|
||||
|
||||
#define r_dtr(x) inb(x)
|
||||
#define r_str(x) inb(x+1)
|
||||
#define r_ctr(x) inb(x+2)
|
||||
#define w_dtr(x,y) outb(y, x)
|
||||
#define w_str(x,y) outb(y, x+1)
|
||||
#define w_ctr(x,y) outb(y, x+2)
|
||||
|
||||
/*
|
||||
* Seems to be sending a command byte to the scanner
|
||||
*
|
||||
*/
|
||||
int udpp_put(int udpp_base, unsigned char command)
|
||||
{
|
||||
int loop,value;
|
||||
|
||||
w_dtr(udpp_base, command);
|
||||
w_ctr(udpp_base, 0x05);
|
||||
|
||||
for (loop=0;loop<10;loop++)
|
||||
if (((value=r_str(udpp_base)) & 0x80)!=0x00) {
|
||||
w_ctr(udpp_base, 0x04);
|
||||
return value & 0xf8;
|
||||
}
|
||||
|
||||
return (value & 0xf8) | 0x01;
|
||||
}
|
||||
|
||||
|
||||
For the UMAX Astra 600P only seven such routines exist (well 14 really, seven
|
||||
for SPP and seven for EPP). Whether you choose to disassemble the driver at
|
||||
this point to verify the routines is your own choice. If you do, the address
|
||||
from the trace should help in locating them in the disassembly.
|
||||
|
||||
You will probably then find it useful to write a script/perl/C program to
|
||||
analyse the logfile and decode them futher as this can reveal higher level
|
||||
grouping of the low level routines. For example from the logs from my UMAX
|
||||
Astra 600P when decoded futher reveal (this is a small snippet)
|
||||
|
||||
|
||||
start:
|
||||
put: 55 8f
|
||||
put: aa 8f
|
||||
put: 00 8f
|
||||
put: 00 8f
|
||||
put: 00 8f
|
||||
put: c2 8f
|
||||
wait: ff
|
||||
get: af,87
|
||||
wait: ff
|
||||
get: af,87
|
||||
end: cc
|
||||
start:
|
||||
put: 55 8f
|
||||
put: aa 8f
|
||||
put: 00 8f
|
||||
put: 03 8f
|
||||
put: 05 8f
|
||||
put: 84 8f
|
||||
wait: ff
|
||||
|
||||
From this it is easy to see that put routine is oftern gouped together in five
|
||||
sucessive calls sending information to the scanner. Once these are understood
|
||||
it should be possible to process the logs further to show the higher level
|
||||
routines in an easy to see format. Once the higest level format that you
|
||||
can derive from this process is understood, you then need to produce a
|
||||
series of scans varying only one parameter between them, so you can
|
||||
discover how to set the various parameters for the scanner.
