I am trying to write a linux device driver for a data acquisition card. The little homepage for my project is at http://mc303.ulyssis.org/heim/ There is already a DOS driver available, and I am trying to port the DOS code right now.
Somewhere in the DOS code, there is some assembler code included:
.RADIX 16 .MODEL SMALL
.486
.CODE
PUBLIC _inpl
_inpl PROC FAR
push bp mov bp,sp
mov dx, Word Ptr [bp+6] in EAX,dx
; bswap EAX
push EAX pop ax pop dx
mov sp,bp pop bp ret _inpl ENDP
PUBLIC _inplI
_inplI PROC FAR
push bp mov bp,sp
mov dx, Word Ptr [bp+6] in EAX,dx
push EAX pop ax pop dx
mov sp,bp pop bp ret _inplI ENDP
PUBLIC _swem
_swem PROC FAR
push bp mov bp,sp
mov EAX, DWord Ptr [bp+6]
bswap EAX
push EAX pop ax pop dx
mov sp,bp pop bp ret _swem ENDP
PUBLIC _outpl
_outpl PROC FAR
push bp mov bp,sp
mov dx, Word Ptr [bp+0ah] mov ax, Word Ptr [bp+8] push ax push dx pop EAX mov dx, Word Ptr [bp+6] out dx,EAX
mov sp,bp pop bp ret _outpl ENDP
PUBLIC _outplI
_outplI PROC FAR
push bp mov bp,sp
mov dx, Word Ptr [bp+8] mov ax, Word Ptr [bp+0ah] push ax push dx pop EAX mov dx, Word Ptr [bp+6] out dx,EAX
mov sp,bp pop bp ret _outplI ENDP
END
I would like to know by what linux native system calls I can replace the commands inpl, inplI, outpl, outplI, swem. I guess the following mapping should do it:
DOS assembler -> Linux
inpl inpl inplI ??? outpl outpl outplI ??? swem ???
Could somebody tell me what function to use where the question marks are written? Are the other mappings from inpl and outpl also correct?
Thanks for helping me out, mc303
PS: The DOS code is also at http://mc303.ulyssis.org/heim
