Sorry for the delay, but holiday season takes its toll (needed to cover a 2nd
project as well).
I've successfully booted a kernel with userspace tsc emulation enabled.
The output from the "tsc" testprogram looks like:
min: 12, max: 21, avg: 12
min: 12, max: 21, avg: 12
min: 12, max: 18, avg: 12
min: 12, max: 21, avg: 12
min: 12, max: 21, avg: 12
min: 12, max: 21, avg: 12
......
Min: 12, max: 26, avg: 12 ->0.180002 us
Does this look correct to you?
I have one question though:
What is the meaning of the min_delay_tick element of the ipipe_timer struct? i
just
Used a random value here.
If the result of the test program looks good to you, i'm going to clean up the
patch and i can post it against a
xenomai 2.6.1 patched 3.2.23 vanilla linux kernel.
