[Xenomai] Which kernel versions?

Does xenomai.org indicate which versions of the vanilla kernel can be
patched with the latest xenomai release?

Basically, any linux version older than the version for which the
patches are provided in xenomai sources, for which an Adeos patch exists in

http://download.gna.org/adeos/patches/

is supposed to work. Except blatant bugs like the one fixed by the
following patch:
http://git.xenomai.org/?p=xenomai-2.6.git;a=commitdiff;h=28984e66e9e17701354f8883b025fcf83f8b0b68;hp=8417949f5e7d1b4483eb3b6344ec5f3124ecf740

Which prevents anything older from 3.2 to run with xenomai 2.6.1 on x86.

How can I tell for which kernel version the patches are provided?  I
believe the latest patches are contained here?

http://download.gna.org/xenomai/testing/

The patches are contained in the ksrc/arch/YOURARCH/patches directory of
xenomai sources.

Where YOURARCH is one of arm, blackfin, nios2, powerpc, sh, x86, etc...

Got it, but I'm still confused by the following definition:

"any linux version older than the version for which the patches are
provided in xenomai sources, for which an Adeos patch exists in:
http://download.gna.org/adeos/patches/"

The patches in 2.6.0-rc5 xenomai sources seem to be for these kernel versions:

2.6.35.9
2.6.37.6
2.6.38.8

And the Adeos patches are for these:

3.0.13
3.0.36
3.2.21

So the above definition doesn't match any versions?

2.6.0-rc5 is not the latest version, 2.6.1 is. For the x86 architecture
for instance, it contains the following patches:

adeos-ipipe-2.6.37.6-x86-2.9-02.patch
adeos-ipipe-2.6.38.8-x86-2.11-01.patch
ipipe-core-3.2.21-x86-1.patch

So, any version earlier than 3.2.21 for which an Adeos patch exists in
http://download.gna.org/adeos/patches/v2.6/x86
http://download.gna.org/adeos/patches/v3.x/x86

Is supported.

That is:
2.6.24
2.6.25
2.6.26
2.6.26.7
2.6.26.8
2.6.27
2.6.27.13
2.6.27.19
2.6.28.2
2.6.28.7
2.6.28.9
2.6.29.1
2.6.29.4
2.6.29.5
2.6.30
2.6.30.5
2.6.30.8
2.6.31
2.6.31.1
2.6.31.8
2.6.32.11
2.6.32.13
2.6.32.15
2.6.32.2
2.6.32.20
2.6.32.7
2.6.34
2.6.34.5

Note that the list is not exhaustive, because it does not includes
patches that were published before the i386/x86_64 merge, if you take
that into account, you can even run Xenomai 2.6.1 with 2.4 kernels.

2.4.25/ppc only though. We stopped maintaining 2.4/x86 setups many moons

Build AND tested, or tested for build? I did not test such configuration
for ages, do you actually test this?

We don't maintain this, I mean we don't test it at all anymore, and we
have no bandwidth to put it back in our manual test routines, and would
these fail, I don't think we should spend a minute fixing it. So we are
left with a decision to let it bit rot, or remove it. Bit rotting of
architecture ports is something we have been trying hard to avoid since
day #1, so removing such support would be consistent with that policy.

Ok, if we remove the support in asm/wrappers.h
