The cyclone v soc GIC interrupt priority issues

Hi,

Please check this below API function, you can also directly set the LEVEL or EDGE triggered.

ALT_STATUS_CODE alt_int_dist_trigger_set(ALT_INT_INTERRUPT_t int_id,

ALT_INT_TRIGGER_t trigger_type)

{

// See GIC 1.0, section 4.3.12.

if ((uint32_t)int_id >= ALT_INT_PROVISION_INT_COUNT)

{

return ALT_E_BAD_ARG;

}

else if ((alt_int_flag[int_id] & INT_FLAG_IMPLEMENTED) == 0)

{

return ALT_E_BAD_ARG;

}

else if (int_id < 16)

{

if ( (trigger_type == ALT_INT_TRIGGER_AUTODETECT)

|| (trigger_type == ALT_INT_TRIGGER_SOFTWARE))

{

return ALT_E_SUCCESS;

}

else

{

return ALT_E_BAD_ARG;

}

}

else

{

uint32_t regoffset = int_id >> 4;

uint32_t regbitshift = ((int_id & 0x0F) * 2) + 1;

if (trigger_type == ALT_INT_TRIGGER_AUTODETECT)

{

if (int_id <= 32) { trigger_type = ALT_INT_TRIGGER_EDGE; } // PPI

else if (int_id <= 40) { trigger_type = ALT_INT_TRIGGER_EDGE; } // CPU0_PARITYFAIL

else if (int_id <= 47) { trigger_type = ALT_INT_TRIGGER_LEVEL; } // CPU0_DEFLAGS

else if (int_id <= 56) { trigger_type = ALT_INT_TRIGGER_EDGE; } // CPU1_PARITYFAIL

else if (int_id <= 63) { trigger_type = ALT_INT_TRIGGER_LEVEL; } // CPU1_DEFLAGS

else if (int_id <= 66) { trigger_type = ALT_INT_TRIGGER_EDGE; } // SCU

else if (int_id <= 69) { trigger_type = ALT_INT_TRIGGER_EDGE; } // L2_ECC

else if (int_id <= 70) { trigger_type = ALT_INT_TRIGGER_LEVEL; } // L2 (other)

else if (int_id <= 71) { trigger_type = ALT_INT_TRIGGER_LEVEL; } // DDR

else if (int_id <= 135) { /* do nothing */ } // FPGA, !!!

else { trigger_type = ALT_INT_TRIGGER_LEVEL; } // everything else

}

switch (trigger_type)

{

case ALT_INT_TRIGGER_LEVEL:

alt_clrbits_word(alt_int_base_dist + 0xC00 + regoffset * sizeof(uint32_t), 1 << regbitshift); // icdicfrn

break;

case ALT_INT_TRIGGER_EDGE:

alt_setbits_word(alt_int_base_dist + 0xC00 + regoffset * sizeof(uint32_t), 1 << regbitshift); // icdicfrn

break;

default:

return ALT_E_BAD_ARG;

}

return ALT_E_SUCCESS;

}

}

"Did you suggest I test the time form the isr signal send to GIC to the interrupt callback function called". Yes in C code only can write piece of code for timer before ISR start and end.
