Hi Philippe,
Kudos for the RTAI/fusion 0.7 release!
You (the team) are doing an astounding work.
[snip]
o The Adeos support used in fusion has been upgraded to final releases,
namely r9/x86 and r6/ppc. Upgrading is strongly recommended, especially
if CONFIG_PREEMPT is enabled in your kernel config, which is likely
with
fusion. Also note that Adeos PPC is now rebased on mainline (2.6.10
actually).
Please find attached a patch of Adeos r6/ppc against 2.6.11.
I hope I've got it right. Please let me know if it would need
the spinlock fix in i386-r10c1.
The patch seemed ok, but the kernel isn't. There's a bug that causes the
plain kernel schedule while in atomic region (see
http://ozlabs.org/pipermail/linuxppc-dev/2005-March/018497.html
)
I don't know if this affects embedded archs, but anything using entry.S
seems to be affected. I wouldn't use 2.6.11 on ppc32.
