I applied linuxolator-p4.diff to CURRENT (as of about 24 hours ago).
Unfortunately the patch did not apply cleanly, so the rejected files
were replaced by appropriate p4 files. Unfortunately I still had the
same problem that I originally reported.
Over this code base, I copied what I thought were the relevant files
from p4 that provided support for (linux_)sched_getaffinity as mentined
by jkim. I had positive results with this setup! However, I also have
some odd observations:
1. Compiling using javac ends in a signal 9 even though it looks like
the program successfully completed compilation.
2. Running sample applications, e.g., demo/jfc/SwingSet2/SwingSet2.jar,
results in an empty pane, where it was expected to be populated with
controls (not sure if this is a toolkit problem); applications also core
3. Running ftpserver (java application) displays a GUI window but
terminates abruptly when the server is started (syscall epoll_create not
Everything seems to run OK with compat.linux.osrelease to 2.4.2.
Note that due to the nature of the build, it could be that some files
are not correctly synchronised, so I will wait for the next patch set.
