|

Parameters:
|

* eax = 41 - function number
|
||||
* ebx = IRQ number, 0..15
|
||||
Returned value:
|

* eax = owner PID

================== Function 42 - work with IRQ data. =================
|
||||
======================================================================
|
||||
When an IRQ occurs, the system reads data from ports indicated
|
||||
earlier by function 44 and writes this data to
|
||||
internal buffer. This function reads out data from that buffer.
|
||||
|
||||
--------------------- Subfunction 0 - read data ----------------------
|
||||
Parameters:
|
||||
* eax = 42 - function number
|
||||
* bl = IRQ number, 0..15
|
||||
* bh = 0 - subfunction number
|
||||
* rest of ebx must be zeroed
|
||||
* ecx = pointer to a buffer with size not less than 4000 bytes
|
||||
Returned value: (use value of eax to distinguish)
|
||||
* if the thread is not IRQ owner
|
||||
(or IRQ number is incorrect): eax = -1
|
||||
* if there is no data: eax = 0
|
||||
* if all is ok:
|
||||
eax = size of data read (in bytes)
|
||||
|
||||
------------- Subfunction 1 - get size of data in buffer -------------
|
||||
Parameters:
|
||||
* eax = 42 - function number
|
||||
* bl = IRQ number, 0..15
|
||||
* bh = 0 - subfunction number
|
||||
* rest of ebx must be zeroed
|
||||
Returned value:
|
||||
* if the thread is not IRQ owner
|
||||
(or IRQ number is incorrect): eax = -1
|
||||
* otherwise eax = size of data in buffer
|
||||
Remarks:
|
||||
* Previously the thread must reserve indicated IRQ for itself
|
||||
by function 45.
|
||||
* The size of data buffer is 4000 bytes, on overflow

======================================================================

they can be read by <20><><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> 42.

Parameters:
|
||||
* eax = 44 - function number
|
||||
* ebx = pointer to the array of structures each describing one port:
|
||||
* +0: word: 0 means end of array, otherwise port number
|
||||
* +2: byte: reserved (ignored)
|
||||
* +3: byte: 1=read byte from this port, 2=read word
|
||||
* ecx = IRQ number, 0..15
|
||||
Returned value:
|
||||
* eax = 0 - success
|
||||
* eax = 1 - the thread is not owner of selected IRQ
|
||||
Remarks:
|
||||
* Previously the thread must reserve for itself selected IRQ

by function 45.

* First 16 ports are considered only.

=================== Function 45 - reserve/free IRQ. ==================
|
||||
======================================================================
|
||||
Parameters:
|
||||
* eax = 45 - function number
|
||||
* ebx = 0 - reserve, 1 = free
|
||||
* ecx = IRQ number, 0..15
|
||||
Returned value:
|
||||
* eax = 0 - success
|
||||
* eax = 1 - error (invalid IRQ number
|
||||
or attempt to reserve not free IRQ
|
||||
or to free IRQ, not reserved by this thread)
|
||||
Remarks:
|
||||
* IRQ reservation is required for functions 42 and 44.
|
||||
* Only one thread can reserve the specific IRQ.
|
||||
* IRQs, handled by the system itself, are reserved by the system
|
||||
(thread 1) at booting.
|
||||
* When a thread terminates, all reserved by it IRQs
|
||||
are freed automatically.
