I don't use a toshiba, but I compile custom kernels, and the default configuration for the Fedora kernel in the latest version from koji, 4.2, has the following toshiba options set. Are these the options you are talking about? CONFIG_YENTA_TOSHIBA=y CONFIG_PATA_TOSHIBA=m CONFIG_MMC_TOSHIBA_PCI=m Thanks for raising the question. I'll be getting rid of them on my next iteration, since they're just wasted bits for me. :-) That's the hard part of compiling a custom kernel; eliminating all the irrelevant modules and functionality. I've looked, and there doesn't seem to be a program that scans the system, and only turns on hardware modules for the system scanned. I'm surprised, actually. And I'm thinking of hacking together something in python that uses lspci and lsmod and /proc to turn off all the drivers I don't need in the .config file. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

This could be a game changer. Yeah, it's a little risky, but my system is very stable, and I only compile kernels when everything is attached and running smoothly. I'm surprised this wasn't mentioned in the build instructions at kernel.org. Or maybe I just missed it. Now I've got to rush off and compile a new kernel. :-) -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

I just compiled a kernel using localmodconfig, and you are exactly right. It set all the modules I didn't need to n, and the kernel compiled a lot more quickly than usual. The size of the kernel was just slightly smaller than previously. It used the configuration of the running kernel as a starting point, so I didn't lose all the other customization I had implemented over the iterations. I'm just about to boot into the new kernel, so the proof of the pudding will soon be apparent. If it boots, as it should, I'll be pleased with this way of building kernels. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Re: Toshiba support in the kernel.
Just as an FYI for those who may not know this, but the Fedora Project has build servers almost constantly building new kernels. You can go to koji.fedoraproject.org and type in kernel in the package field. Or go to URL http://koji.fedoraproject.org/koji/packageinfo?packageID=8 For example today's built kernels already are: kernel-4.0.7-300.fc22 kernel-4.0.7-200.fc21 And for the bleeding edgers, yesterday's build was: kernel-4.2.0-0.rc0.git2.1.fc23 For the uninitiated, be aware the git kernels often have kernel debugging enabled and will run slower. Typically the first (U.S.) work day after a kernel release, there will be non-debug and debug kernels listed; but when a debug kernel is not listed that means all of those builds are debug kernels. So it's possible to completely avoid building kernels if you don't have special customizations you need done, and yet get very recent kernel versions.
