Hi,
We are running our tests now where Linux is bombarded with interrupts. Under
certain conditions
we found that we get page faults in IRQ Tasks which cause a secondary mode
switch. To my understanding
and what makes things worse is that, ISR tasks always run with the scheduler
lock bit set (T_LOCK).
In our case this means that when we switch to the secondary mode from the ISR
Task, all other Xenomai
tasks don't get scheduled until the ISR task returns to primary mode. Since
Linux is under heavy
interrupt load, it takes about 1-2sec for any Xenomai task to start running
again.
I attached a LTTng trace where you can see whats going on. Here the short
version:
1) IRQ 44 occurs
2) Xenomai kernel-space ISR is called and wakes up the user-space ISR task,
called "00000039"
3) We get the page fault just at the start of the user-space ISR:
xn_nucleus.thread_fault: 208.180295561 (/tmp/trace-ktrigger1/xn_nucleus_0), 4,
4, events/0, , 2, 0x0, SYSCALL { thread = 0xe1075610, thread_name = "00000039",
address = 269713436, type = 769 }
Address: 0x1013801c
Type: 0x301 (Data access exception according to PowerPC e300 core manual)
4) Switch to secondary mode
5) After 2sec the task resumes
My research also led me to the following xenomai-help ng post:
http://www.mail-archive.com/[email protected]/msg04716.html
Back then (in 2007), Philippe was saying that the Ipipe/powerpc port didn't
support disabling of
the 'demand paging' mechanism. Has someone already implemented this for powerpc?
What other options do we have?
Regards, Andreas
