[opensuse-kernel] kernel-source-rt what is it?
Hi, I just tried zypper in kernel-pa* kernel-s* in order to obtain the latest kernel-pae and kernel-source and syms packages from factory and zypper wanted to install kernel-source-rt and kernel-syms-rt. What is the effect, are these preconfigured real time kernel source and sym packages and would make cloneconfig simply turn them into normal sources? Are they safe to use for nvidia run packages?

Yes.

No, they would be installed on your machine.

No way in hell. All kernel modules need to be rebuilt specially to use the -rt kernels. If you don't really know what the -rt kernels do, you really don't want to be messing around with them, overall they will slow your machine down, and probably make funny faces at your cat, annoying it to no end. good luck, greg k-h -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

I don't think that was the question. Dave, the -rt packages are "special." All other kernel flavors use a unified source tree, where changes between them are just configuration differences. The differences are handled in the /usr/src/linux-obj hierarchy. The -RT has changes that are large, pervasive, and fundamentally different in places that require us to ship a completely different source tree. It's not just a configuration difference. A "make cloneconfig" might complete successfully, but I doubt it. Even if it did, you'd end up with a result very different from the configuration you cloned. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAkka2XwACgkQLPWxlyuTD7J+ZwCfV21owrCEsoeGBGW4/FxLstxp 1c4AniPDFcFdGOipNdn7FDmrl7RShbpO =zItU -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

Thanks for reply, I see the source-rt package has disappeared from factory anyway. I think my main problem is that factory has kernel-source/sym i586 packages out of sync version wise with default and pae packages. They now have kernel-source-2.6.27.5-2.1.i586 and kernel-pae-2.6.27.5-2.2, this morning it was kernel-pae-2.6.27.5-1.1.i586 with the same source package. I'm going to keep my head down until the dust has settled in factory and in future read version and build numbers more carefully. It was the wrong day to attempt upgrade.
