Hello,
Can someone tell me if QNX 4.25 will work on a Pentium 4?
Thanks,
Tom.
Yes, it works.

Yes, it works.
But the OS will report the wrong CPU frequency (qnx_osinfo() )

If you’re refering to the cpu_speed member, it’s not a CPU frequency, just a
benchmark value. But, you’re correct in that it will appear to wrap and
give wierd values because of the size of the container (it actually
calculates it ok). I’ve addressed the issue by capping the result to
0xffff. In addition, I’m also stuffing the cpu frequency in khz into the
osinfo struct now using some of the reserved space (member is cpu_khz) so
the benchmark (cpu_speed) is less important now without breaking anyone
still using it.

Sorry I got it wrong I was talking about cpu_features with should be able to
report speed up to 4095 Mzh but doesn’t work on P4 (don’t know if it’s
related to P4 or to the higher frequence). P4 is running at 2.2G so there
is enough bit to represent 2200Mzh. The value seems to be a third of the
actuall frequency. The value reported by cpu_feature&0xfff is the same as
the one display when Proc starts, which is what lead me to beleive the
calculation is off and not the representation.

If memory serves, it the /boot util that fills in the speed for that (since
proc doesn’t make reference to cpu_features anywhere). I’ll take a peek
later to see why it doesn’t report properly all the time.

In what version of Proc is this new member setup. At what offset in the
osinfo structure is it located.

It’s not released, but should be whenever the next QNX4 update is scheduled.
The offset as reported by offsetof(struct _osinfo, cpu_khz) is 0x8E

If you ever fix the boot/clock problem drop me a note and I’ll see about
getting a copy via support plan.
