State of Linux-RT Patches and full inclusion into linus tree

State of Linux-RT Patches and full inclusion into linus tree

[Shawn Starr]

Hello, 

I was wondering if (or ever) will the full Linux RT patches be merged into 
Linus's tree? If not, what is preventing this? I know bits of this has been 
leaking into 2.6.x over the years.

Thanks,
Shawn.

One of the key parts of the RT patchset, is already mainline - and was
merged in 2.6.39. - Forced Interrupt Threading. it can be enabled in
the kernel config. From what i understand there are other bits and
pieces to the RT patchset. But this was the most significant.. it is
certainly mainline and has been available for quite a while now. I am
typing from a computer that has it enabled, as i write to you now.

myself, i used RT for proaudio ~ i do not require RT anymore, at all.
my applications always meet their 'deadlines' with very low-latency
and work the way they are supposed too.

someone else can clarify on the bits of RT are still to be merged, as
i don't know. i just remember someone talking about that a few months
ago on the list. maybe that has changed. I had also read there was
supposed to be another RT release, but your posting is the first on
this list in a long time.

That article contains the following sentence:

  "There are plans to update to 2.6.38 soon."

Just out of curiosity, is that update under way?
