Hi,
This is to let you know that the UST in the git repository now
supports the PowerPC 32 architecture.

Testing is welcome.
This will be in the next release.
This port seems to rely on do_gettimeofday. Any plan to add ppc tb
register-based trace clock ?
Hi Mathieu,
I did some tests. On my ppc32 system, this counter wraps in about 2
minutes. Will LTTV tolerate well a wrapping time base?
ppc32 timebase is two separate registers, timebase upper and lower. I could
certainly see the lower register (lower 32 bits) wrapping in about 2 min, but
the upper should continue on.
Thanks. Indeed there was a problem in my quick test implementation. ;-)
I pushed the code to the repo. To activate the "native" time source, one
must comment the
#define TRACE_CLOCK_GENERIC
line in clock.h.
For now there is no trace_clock_frequency() function for this time
source so it is disabled by default.
