Hi,
I have tried the rt patches available on kernel.org. Unfortunately none patches correctly with latests kernel !

Where can I download the good ones ?
Regards,
Steph

did you try the patches located at
https://www.kernel.org/pub/linux/kernel/projects/rt/ ?
Use the corresponding mainline kernel, for example if you want to use 3.18.13-rt10, download linux 3.18.13 (from torvald's repo for example) and apply the rt patch on it .
Latest rt patches are for linux 3.18 and 4.0, so if you use the correct version it should work just fine.

Everything is explained on the wiki,
Regards,
Romain

It appears you are applying the patch to an Android or other third-party derivative of Linux, instead of Linux proper, or that either the kernel or the patch you have fetched is corrupt. Try re-fetching everything and try again. This sequence works for me:

cd
mkdir junk
cd junk
wget -q ftp://ftp.kernel.org/pub/linux/kernel/v3.0/linux-3.18.11.tar.xz wget -q ftp://ftp.kernel.org/pub/linux/kernel/projects/rt/3.18/patch-3.18.13-rt10.patch.xz tar xf l*xz
cd linux*11
unxz <../pat*xz | patch -p1

There are some (annoying) offset errors, but no fuzzies or rejects like you have been seeing.

I think the reason you see offset errors is that you are trying to patch 3.18.11 with the 3.18.13 RT patch. A quick test here substituting with :

wget -q
ftp://ftp.kernel.org/pub/linux/kernel/v3.0/linux-3.18.13.tar.xz
gives no such errors!
Andy.

It looks like this is a proxy related problem....

using wget I am unable to use ftp://, but http:// is downloading, however this does not work with the files retrieved.

can you give me working md5sum of files downloaded ? Regards,

"These checksums are NOT intended to replace the web of trust. It is merely a way for someone to quickly verify whether contents on one of the many kernel.org mirrors match the contents on the master mirror. While you may use them to quickly verify whether what you have downloaded matches what we have on our central storage system, you should still use the GPG web of trust to verify whether the release tarball actually matches what the kernel developer published." -

here is an example with linux-3.18.13 and patch 3.18.13-rt10:
3.18.13-rt10
zcat ../patches-3.18.13-rt10.tar.gz |patch -p1 --dry-run

You are trying to apply a tarball of patches instead of a single combined patch. Use patch-3.18.13-rt10.gz instead.

Thanks,
