Xilinx xapp1052 xbmd.ko cant' load

[tibacou]

Hey

I am doing the xapp1052, I use a host computer linux and the version of the kernel is 2.6.32-358.11.1.el6.x86_64 after the compilation I want load the file xbmd.ko unfortunately it'snt work. Is it problem with my version of kernel ? I search a solution about my problem but I don't find. If you have experience about this problem you can share your experience.

In the terminal I have this message. 

[root@tibacou xbmd]# insmod xbmd.ko
insmod: error inserting 'xbmd.ko': -1 Operation not permitted

My board sp605 is detected by the host computer 

[root@tibacou xbmd]# lspci

03:00.0 Memory controller: Xilinx Corporation Device 0505

Best REgards.

This recall me a problem I had.

I'm pretty sure that there is an old thread that give some solutions about that.

In my memory it was an issue regarding your Kernel version and/or about MSI interuption

Some old piece of code :

 //enabling msi if possible
    if ( 0 != pci_enable_msi (dev) )
    {
        printk(KERN_INFO"%s: Warning : MSI are not supported by mother board\n", gDrvrName);
    }
    else
    {
        dp->driverStatus = dp->driverStatus | HAVE_MSI;
        printk(KERN_INFO"%s: MSI are supported by mother board\n", gDrvrName);
    }

#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,21)
    err=request_irq(dev->irq,my_isr, IRQF_SHARED,my_sname,dp);
#else
    err=request_irq(dev->irq,my_isr, SA_SHIRQ,my_sname,dp);
#endif

What is your kernel version, I stopped to use my driver at version 2.6.28

I use the version Linux tibacou 2.6.32-358.11.1.el6.x86_64 I search on the forum but I did'nt found a solution about my problem.

[tibacou]

In the code source if (0 > request_irq(gDev->irq, &XPCIe_IRQHandler, IRQF_SHARED | IRQF_SAMPLE_RANDOM, gDrvrName, gDev)) { printk(KERN_WARNING"%s: Init: Unable to allocate IRQ",gDrvrName); return (CRIT_ERR); } The function request_irq return a value != 0 there is problem with code source of Xilinx.

[zben]

Yes it must return something >0

You should try the function : enable_msi as I said

Or maybe add :

pci_set_master(dev);

 just before requesting the irq
