Subject: [Xenomai-core] Xenomai v2.1-rc2
Date: Sat, 14 Jan 2006 11:33:32 +0100 [thread overview]
Message-ID: <43C8D37C.4070302@domain.hid> (raw)
-rc2 has been released [1]. It looks like people have been rather busy with this
one; here is what's new since -rc1, in no particular order:
- The ARM port [Stelian]. This work has been co-sponsored by the Video Compression
and Networking group from Thomson Grass Valley [2], and Openwide. This
initial port has been conducted on an Integrator/CP board featuring an ARM 1136 core.
- POSIX skin updates [Gilles].
- Allow building the kernel from within the Xenomai tree [Gilles]. This is for
those who dislike having to deal with compiling the kernel and user-space trees
separately.
- Major bug fix regarding the hybrid scheduling feature, i.e. the ability to make
transitions between kernel-based and user-space Xenomai threads [me, Heikki].
Basically all archs are concerned by this fix, but x86 which had no problem
regarding this issue. As Heikki put it once rather politely in the light of such a
mess, "A good test-suite seems like a must". Ahem, yeah...
- Provide support for 2.6.15/x86 [me]. Other archs will follow.
- Upgrade to the most recent I-pipe series for all archs, allowing to shorten the
interrupt path a bit [Dmitry].
- RTDM-based benchmark suite [Jan]. Our good ol' kernel-based latency test is up
and running again, along with a new timer-only benchmark. This code exploits the
I-pipe's new latency tracer for x86 [Jan].
And a slew of fixes and cleanups all over the map. See the ChangeLog for details
as usual.
As a sidenote, now that all archs have a reliable and complete I-pipe support, the
oldgen Adeos patches have been deprecated, and support for them has been dropped
from the codebase.
Next step is -rc3, hopefully the last one before final, scheduled for the first
week of February, which de facto postpones v2.1 final for a couple of weeks or so.
I'm going off-line from now to the end of January. Gilles will take the reins
during that period.
