Subject: [Xenomai] Backport Xenomai-26 to Linux 2.6.29.1
Date: Fri, 08 Feb 2013 09:57:38 +0100 [thread overview]
Message-ID: <5114BE02.6040901@sirius-es.it> (raw)
Hi,
We decided to try to backport the
adeos-ipipe-2.6.36.4-powerpc-2.12-05.patch against the Linux 2.6.29.1
kernel but we encountered problems with spinlock handling:
In the 2.6.29 kernel, we found some differences about spinlock
structures hierarchy. In detail at kernel side we have only
raw_spinlock_t and spinlock_t but xenomai (ipipe_lock.h) uses
arch_spinlock_t, raw_spinlock_t and spinlock_t.
Those differences will force us to heavily modify the spinlock handling
in the xenomai patch, deleting a layer and replacing arch_spinlock_t
with raw_spinlock_t and raw_spinlock_t with spinlock_t.
Is there an old patch file that contains spinlock handling compliant
with 2.6.29.1 kernel and xenomai 2.6?
Regards,
Matteo Facchinetti
