- UNDI ISR
- Op-Code: PXENV_UNDI_ISR (0014h)
- Input: Far pointer to a PXENV_UNDI_ISR_T parameter structure that has been initialized by the caller.
- Output: PXENV_EXIT_SUCCESS or PXENV_EXIT_FAILURE must be returned in AX. The status field in
- the parameter structure must be set to one of the values represented by the PXENV_STATUS_xxx
- constants.
- Description: This API function will be called at different levels of processing the interrupt. The FuncFlag field in
- the parameter block indicates the operation to be performed for the call. This field is filled with the
- status of that operation on return.
- Note: Interrupt Service Routine Operation:
- In this design the UNDI does not hook the interrupt for the Network Interface. Instead, the
- application or the protocol driver hooks the interrupt and calls UNDI with the PXENV_UNDI_ISR
- API call for interrupt verification (PXENV_UNDI_ISR_IN_START) and processing
- (PXENV_UNDI_ISR_IN_PROCESS and PXENV_UNDI_ISR_GET_NEXT).
- When the Network Interface HW generates an interrupt the protocol driver interrupt service
- routine (ISR) gets control and takes care of the interrupt processing at the PIC level. The ISR then
- calls the UNDI using the PXENV_UNDI_ISR API with the value PXENV_UNDI_ISR_IN_START for
- the FuncFlag parameter. At this time UNDI must disable the interrupts at the Network Interface
- level and read any status values required to further process the interrupt. UNDI must return as
- quickly as possible with one of the two values, PXENV_UNDI_ISR_OUT_OURS or
- PXENV_UNDI_ISR_OUT_NOT_OURS, for the parameter FuncFlag depending on whether the
- interrupt was generated by this particular Network Interface or not.
- If the value returned in FuncFlag is PXENV_UNDI_ISR_OUT_NOT_OURS, then the interrupt was
- not generated by our NIC, and interrupt processing is complete.
- If the value returned in FuncFlag is PXENV_UNDI_ISR_OUT_OURS, the protocol driver must start
- a handler thread and send an end-of-interrupt (EOI) command to the PIC. Interrupt processing is
- now complete.
- The protocol driver strategy routine will call UNDI using this same API with FuncFlag equal to
- PXENV_UNDI_ISR_IN_PROCESS. At this time UNDI must find the cause of this interrupt and
- return the status in the FuncFlag. It first checks if there is a frame received and if so it returns the
- first buffer pointer of that frame in the parameter block.
- The protocol driver calls UNDI repeatedly with the FuncFlag equal to
- PXENV_UNDI_ISR_IN_GET_NEXT to get all the buffers in a frame and also all the received
- frames in the queue. On this call, UNDI must remember the previous buffer given to the protoco,l
- remove it from the receive queue and recycle it. In case of a multi-buffered frame, if the previous
- buffer is not the last buffer in the frame it must return the next buffer in the frame in the parameter
- block. Otherwise it must return the first buffer in the next frame.
- If there is no received frame pending to be processed, UNDI processes the transmit completes and
- if there is no other interrupt status to be processed, UNDI re-enables the interrupt at the
- NETWORK INTERFACE level and returns PXENV_UNDI_ISR_OUT_DONE in the FuncFlag.
- IMPORTANT: It is possible for the protocol driver to be interrupted again while in the
- strategy routine when the UNDI re-enables interrupts.

- UNDI ISR
- Op-Code: PXENV_UNDI_ISR (0014h)
- Input: Far pointer to a PXENV_UNDI_ISR_T parameter structure that has been initialized by the caller.
- Output: PXENV_EXIT_SUCCESS or PXENV_EXIT_FAILURE must be returned in AX. The status field in
- the parameter structure must be set to one of the values represented by the PXENV_STATUS_xxx
- constants.
- Description: This API function will be called at different levels of processing the interrupt. The FuncFlag field in
- the parameter block indicates the operation to be performed for the call. This field is filled with the
- status of that operation on return.
- Note: Interrupt Service Routine Operation:
- In this design the UNDI does not hook the interrupt for the Network Interface. Instead, the
- application or the protocol driver hooks the interrupt and calls UNDI with the PXENV_UNDI_ISR
- API call for interrupt verification (PXENV_UNDI_ISR_IN_START) and processing
- (PXENV_UNDI_ISR_IN_PROCESS and PXENV_UNDI_ISR_GET_NEXT).
- When the Network Interface HW generates an interrupt the protocol driver interrupt service
- routine (ISR) gets control and takes care of the interrupt processing at the PIC level. The ISR then
- calls the UNDI using the PXENV_UNDI_ISR API with the value PXENV_UNDI_ISR_IN_START for
- the FuncFlag parameter. At this time UNDI must disable the interrupts at the Network Interface
- level and read any status values required to further process the interrupt. UNDI must return as
- quickly as possible with one of the two values, PXENV_UNDI_ISR_OUT_OURS or
- PXENV_UNDI_ISR_OUT_NOT_OURS, for the parameter FuncFlag depending on whether the
- interrupt was generated by this particular Network Interface or not.
- If the value returned in FuncFlag is PXENV_UNDI_ISR_OUT_NOT_OURS, then the interrupt was
- not generated by our NIC, and interrupt processing is complete.
- If the value returned in FuncFlag is PXENV_UNDI_ISR_OUT_OURS, the protocol driver must start
- a handler thread and send an end-of-interrupt (EOI) command to the PIC. Interrupt processing is
- now complete.
- The protocol driver strategy routine will call UNDI using this same API with FuncFlag equal to
- PXENV_UNDI_ISR_IN_PROCESS. At this time UNDI must find the cause of this interrupt and
- return the status in the FuncFlag. It first checks if there is a frame received and if so it returns the
- first buffer pointer of that frame in the parameter block.
- The protocol driver calls UNDI repeatedly with the FuncFlag equal to
- PXENV_UNDI_ISR_IN_GET_NEXT to get all the buffers in a frame and also all the received
- frames in the queue. On this call, UNDI must remember the previous buffer given to the protoco,l
- remove it from the receive queue and recycle it. In case of a multi-buffered frame, if the previous
- buffer is not the last buffer in the frame it must return the next buffer in the frame in the parameter
- block. Otherwise it must return the first buffer in the next frame.
- If there is no received frame pending to be processed, UNDI processes the transmit completes and
- if there is no other interrupt status to be processed, UNDI re-enables the interrupt at the
- NETWORK INTERFACE level and returns PXENV_UNDI_ISR_OUT_DONE in the FuncFlag.
- IMPORTANT: It is possible for the protocol driver to be interrupted again while in the
- strategy routine when the UNDI re-enables interrupts.

- Primary bus # = 2

-; This template must be copied into low memory, and the IDT entries
-; 0x68-0x6F must be point to the low memory copy of this code. Each
-; entry is 4 bytes long, so IDT entries 0x68-0x6F can be easily
