Hi,
The for-core-3.5.7 and for-core-3.8.2 branches in ipipe_gch.git
repository contain new versions of the I-pipe kernel for the ARM
architecture.
The for-core-3.5.7 branch contains an important fix for SMP platforms,
and the fix for mx28 posted by Martin Krause.
The for-core-3.8.2 branch is the newest port. Known issues are:
- it has been rebased on v3.8.2, so it will not merge with the branch
it started from, if preferred, I can push a merged version;
- ftrace is broken, so I wonder if it would not be simpler to have a
tracer not relying on ftrace, as we did at the beginning of the I-pipe
tracer;
- threaded fasteoi irqs are broken, the branch contains the latest
patch posted on this list, but since I received no comment, I am not
sure it is the right fix.
The pull requests follow.
