C++ (Cpp) unmask_module_irq Examples

Example #1

{
    volatile unsigned int* base = 0;

    unsigned int clr_bit = 0x3 << ((module % MOD_NO_IN_1_DEVAPC) * 2);
    unsigned int set_bit = permission_control << ((module % MOD_NO_IN_1_DEVAPC) * 2);

    clear_vio_status(module);
    unmask_module_irq(module);

    if(domain_num == E_DOMAIN_0)
    {
        
        base = (unsigned int*) ((size_t)DEVAPC_D0_APC_0 + (module/16) *4);
    }
    else if(domain_num == E_DOMAIN_1)
    {
        base = (unsigned int*) ((size_t)DEVAPC_D1_APC_0 + (module/16) *4);
    }
    else if(domain_num == E_DOMAIN_2)
    {

    }
    else if(domain_num == E_DOMAIN_3)
    {
        base = (unsigned int*) ((size_t)DEVAPC_D3_APC_0 + (module/16) *4);
    }
     writel(readl(base) & ~clr_bit, base);
     writel(readl(base) | set_bit, base);
