I tried to send this to darwin-kernel a few days back, but I can't see it in the archives so I'll try again... I've been looking at the set of kernel benchmarks released on opensolaris.org (http://www.opensolaris.org/os/community/performance/ libmicro/) and got most of them running on Darwin except for a few, so I'd like some of you're thoughts on this. Whenever I run some of the tests I get a "resource temporarily unavailable" error, leading me to think I've hit the vfork bug described at http://sysnet.ucsd.edu/~bellardo/darwin/vfork.html, although I also get these on file locking tests. Firstly, changes I made to the distribution to get it running on Darwin (Mac OS X 10.4.1-> Darwin Kernel Version 8.2.0): I used the Linux makefile as a basis since it contained the least amount of compiler flags and gcc is the c compiler most will use on both systems. $ diff Makefile.com Makefile.com.Darwin 112c112 < $(CC) -o tattle $(CFLAGS) -I. ../tattle.c libmicro.a -lrt -lm ---

$(CC) -o tattle $(CFLAGS) -I. ../tattle.c libmicro.a -

lSystem -lm It seems like rt isn't available on Darwin (at least not on Mac OS X 10.4.1), so I used System as per the suggestion found here http:// www.eca.cx/ecasound-list/2004/10/0056.html. It compiled fine, but I'd like suggestions on this. $ diff Makefile ../libMicro-0.3.0.orig/Makefile 72c72 < @mkdir -p bin-`arch`; cd bin-`arch`; MACH=`arch` $(MAKE) - f ../Makefile.`uname -s` $@ ---

@mkdir -p bin-`uname -m`; cd bin-`uname -m`; MACH=`uname -m`

$(MAKE) -f ../Makefile.`uname -s` $@ uname -m on OS X/PPC returns "Power Macintosh", and the scripts couldn't cope with the space (especially with copy commands in there!). arch seems to be a decent substitute, but it doesn't take any arguments on OS X so I also had to replace the arch -k in bench. My main concern is with the cascade_fcntl, cascade_flock, cascade_lockf, fork, exit tests, in which whenever I add the cascase_* tests to the benchmark script I get the "resource temporarily unavailable" error, and the fork and exit tests just seem to hang. Regarding the cascade_* tests, it definitely seems that Darwin has some sort of limit on the amount of file locks it is willing to create. Is there some way I can control this? I'm not so sure about the fork and exit tests though. Any ideas on this would be greatly appreciated.
