RT Patch to use for Kernel 3.2.0

RT Patch to use for Kernel 3.2.0

[Jing Shao]

Dear sir,

I am trying to patch a Linux 3.2.0 kernel with PREEMPT_RT patch, I tried the patch-3.2.64-rt94.patch.gz, but the Linux kernel fails to compile afterwards, is this the right patch to use?

For your info, the ouput of "uname -r" is 3.2.0. The kernel comes in as part of the SDK for a TI Sitara processor.

Your help are greatly appreciated.

RE: RT Patch to use for Kernel 3.2.0

Pavel,

After patching the kernel 3.2.0 with 3.2.64-rt94, I am getting build errors, which made me think that I am using the wrong patch file.

I see there is old patch files for 3.2.xx, but none for 3.2.0.

Regards,

Jing

You don't want to use 3.2.0. There is a pile of fixes available. So
switch to 3.2.66 and try to apply the patch from 3.2.64-rt94 on top of
that.

Best regards
Uwe
