Thanks for the info,
i have to modify the dtrace script (see below), and I am not
sure if the time statement is ok. Timestamp is in nanoseconds,
so I think correct is "...((timestamp - self->follow) > 5)/" ??
But I'm happy, I have the first results (without timestamp) and now
I try to understa
Hi,
I have posted a second discussion in the DTRACE area.
There I have posted my first results of my dtrace test.
You can find it with supject:"dtrace within driver runtime" posted
by sigi.
I have used the on-cpu and off-cpu probes, but no results.
I will try the ::interrupts probe again.
thank

Hi,
thanks for your ideas.
Normally my transfer of one byte needs about 3 - 4 microseconds (i have
mentioned). Sometimes we need up to 50 - 80 microseconds for one byte.
So i think other threads or processes gets the cpu and my driver was
interrupted.
I have done some dtrace tests, but up to no

Hi,
I have written a driver for a special PCI Card on Solaris 10, Dual Core 2,4 GHz.
The application uses the driver via ioctl to get one byte from the PCI Card.
I use ddi_getxx to read the registers of the PCI Card, locked with mutex_enter
and mutex_exit.
Between ioctl_entry and ioctl_return (wit
