You will then need to load the ib_core and ib_mad modules by hand if you are not loading your driver first. It would likely pull them in based on the dependencies in your driver. -- Hal > Thanks a lot in advance, > Suri > > > -Original Message- > > From: Hal Rosenstock [mailto:[EMAIL PROTECTED] > > Sent: Monday, October 17, 2005 4:42 PM > > To: Suresh Shelvapille > > Cc: openib-general@openib.org > > Subject: Re: [openib-general] initialization -udev > > > > Hi Suri, > > > > On Mon, 2005-10-17 at 16:15, Suresh Shelvapille wrote: > > > Folks: > > > Another basic question, I just built my 2.6.10 kernel with core > > Infiniband > > > stack.

There are *no* modules if you select =y. =m means build a as a module.

RE: [openib-general] initialization -udev
1. I did not add the CONFIG_INFINIBAND=y by hand. I used make menuconfig and the GUI let me choose "y" to select the Infiniband core. And the result was, in .config which I presume is the one generated by the GUI has CONIFG_INFINIBAND=y. >From what you say, the ib_core and ib_mad modules are not loaded if CONFIG_INFINIBAND=y and not 'm'? 2.

You should do an /sbin/lsmod | grep ib_ and see that ib_mthca (or whatever your driver is), ib_mad, and ib_core are loaded.

What should I see to confirm that the core Suresh> Infiniband stack is loaded correctly? If you have set all config options to 'y' or 'n' then there are no IB kernel modules to load. I don't think anything is be printed by the core IB stack so I wouldn't expect to see anything when it loads. You could add a printk() to ib_core_init() if you're worried. BTW, any particular reason you are using such an old kernel instead of 2.6.13 or 2.6.14-rc4? - R. ___ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
