Detailed Description

Function definitions for interrupt routing routines.

-------------------------------------------------------------------------

Description:

This file provides functions for primary and miscellaneous PowerPCI interrupt routing. Functions for routing PID interrupts are defined in ppciPid.h. Functions for routing multiprocessor signal interrupts are defined in ppciMp.h. Note that ppciPtim.c provides timer interrupt routing functions that wrap the miscInt*() functions defined here. Also note that typical RAD750 BSPs define the standard VxWorks interrupt routines (intEnable(), intDisable() and intConnect()) for routing PCI interrupt signals wired into PowerPCI PIDs.

Define Documentation

#define P60X_INT_STATUS_MASK   (OCB_IF_ERR | ADDR_OUT_OF_RANGE | MEM_CTRL_IF_ERR)
 

The valid P60X status bits to interrogate.

Function Documentation

STATUS miscIntConnect (  miscIntLvl_t  intLvl,
VOIDFUNCPTR  isr,
int  parm
) 
 

Connect ISR to PowerPCI MISC interrupt level.

Connect ISR to PowerPCI MISC interrupt level

This routine connects an interrupt service routine (ISR) to PowerPCI bridge MISC interrupt level. Note that the MISC interrupts include the programmable timer interrupts (PTIM). MISC interrupts are enabled separate from this routine (by miscIntEnable()). The interrupt level being connected should not be enable when this routine is called. The specified ISR will get control with interrupts disabled.

Parameters:
intLvl - The PPCI MISC interrupt level.
isr - Pointer to the ISR.
parm - A user-defined parameter to pass to the ISR when the interrupt occurs.
Returns:
OK or ERROR

STATUS miscIntDisable (  miscIntLvl_t  intLvl  ) 
 

Disable a PowerPCI MISC interrupt level.

Disable a PowerPCI MISC interrupt level

This routine disables the specified MISC interrupt level of the PowerPCI bridge. Note that the MISC interrupts include the programmable timer interrupts (PTIM).

Parameters:
intLvl - The PPCI MISC interrupt level to disable.
Returns:
OK or ERROR

STATUS miscIntEnable (  miscIntLvl_t  intLvl  ) 
 

Enable a PowerPCI MISC interrupt level.

Enable a PowerPCI MISC interrupt level

This routine enables the specified MISC interrupt level of the PowerPCI bridge. The Note that the MISC interrupts include the programmable timer interrupts (PTIM).

Parameters:
intLvl - The PPCI MISC interrupt level to enable.
Returns:
OK or ERROR.

STATUS p60xErrIntConnect (  pciIntLvl_t  intLvl,
VOIDFUNCPTR  isr,
int  parm
) 
 

Connect ISR to PowerPCI P60X error interrupt level

This routine connects an interrupt service routine (ISR) to PowerPCI bridge P60X error interrupt level. P60X error interrupts are enabled separate from this routine (by p60xErrIntEnable()). The interrupt level being connected should not be enabled when this routine is called. The specified ISR will get control with interrupts disabled.

Parameters:
intLvl - The PPCI P60X error interrupt level.
isr - Pointer to the ISR.

STATUS ppciIntConnect (  ppciIntLvl_t  intLvl,
VOIDFUNCPTR  isr,
int  parm
) 
 

Connect ISR to PowerPCI interrupt level.

Connect ISR to PowerPCI interrupt level

This routine connects an interrupt service routine (ISR) to PowerPCI bridge interrupt level. PPCI interrupts are enabled separate from this routine (by ppciIntEnable). The interrupt level being connected should not be enable when this routine is called. The specified ISR will get control with interrupts disabled.

STATUS ppciIntDisable (  ppciIntLvl_t  intLvl  ) 
 

Disable a PowerPCI interrupt level.

Disable a PowerPCI interrupt level

This routine disables the specified interrupt level of the PowerPCI bridge.

Parameters:
intLvl - The PPCI interrupt level to disable.
Returns:
OK or ERROR.

STATUS ppciIntEnable (  ppciIntLvl_t  intLvl  )

void ppciIntInit (  void   ) 
 

Interrupt initialization routine, first part.

This init routine is called by ppciInit (from sysHwInit) during system boot. Interrupt routing resources are initialized.

void ppciIntInit2 (  void   ) 
 

Interrupt initialization routine, second part

This init routine is called by ppciInit2 (from sysHwInit2) during system boot. Default handlers are installed for the PPCI error interrupts.
