Linux Driver for xapp1022 and xapp1052

blueisaak · ‎11-16-2010

Hi,

I am trying to run the xapp1022 to test the POI design for PCI Express. I am running Fedora Core 13 with the kernel 2.6.34.7-61.fc13.x86_64. As far as I can tell the Problem is that the Linux drivers use a function called pci_find_slot witch got removed from this kernel version.
Same problem occurs with xapp1052 witch has a similar driver.

I get the fallowing output for the make command:

[root@student0815 /my_code_dir/xapp1022/Linux_Driver]$make

Has anyone an idea how to solve this? Or are there new Linux drivers available?

Try to replace 'pci_find_device' with 'pci_get_device' .

Thanks it worked!

Hi, I had the same problem and had to make that change as well. Now I'm getting an error trying to do the "insmod xpcie.ko" step saying "Operation not permitted" even though I am root. Since you have the same version of Redhat as me I thought I'd ask, did you have this problem and find a way around it?

Thanks.

Hello,

I have the same problem when I'm trying to do the "insmod xpcie.ko" step.

It's return "Operation not permitted".

Do you find a solution?

Thank you.

It seems you are trying to insert the driver file into your kernal.

Please give the root access to insert the driver into the kernel.

You should login as a root to insert the driver into the kernel.

Hello,

Did you guy problems with Fedora 13 to make the project?? I cannot to make the xapp1022 project. I get the following output for make command:

[root@localhost Linux_Driver]# make
make -C /lib/modules/2.6.33.3-85.fc13.i686/build M=/home/curro/Linux_Driver modules
make: *** /lib/modules/2.6.33.3-85.fc13.i686/build: No such file or directory. Stop.
make: *** [all] Error 2
[root@localhost Linux_Driver]#

Maybe I have to configure properly my Linux?? How did you configurate Linux to complie this project??

Thanks!

it's about kernel version,you should make version as below as you can

bg2bkk · ‎11-16-2012

oh sorry I make mistake.it's not about version. You see the notice "make: *** /lib/modules/2.6.33.3-85.fc13.i686/build: No such file or directory. Stop." .It's about that when you complie drivers or kernel modules, "make" will go to directory"/lib/module/your-source-code-tree/build" to reference something. So you shoulde make sure your path" /lib/modules/2.6.33.3-85.fc13.i686/build" is correct
