Maybe Ingo can look at it, and find a way to implement it more
generic? (In the softirq_info struct we could default set all prios

This series changes the PREEMPT-TRACE behavior for reporting critical
sections. The previous code reported 2 frames per section. The new code uses
the save_stack_trace facility to save an arbitrary number of frames (currently
set to 5 via a #define)
For what its worth, these patches assisted me
Hi,
I've been experiencing problems with the megaraid_sas driver under
some simple stress testing when using the rt patch. Simply running:
cat /dev/sda /dev/null
will after a while make the driver start sending this to the logs:
sd 0:2:0:0: [sda] megasas: RESET -285224 cmd=28 retries=0
Hello Steven,
Actually, the handler thread runs _all_ register interrupt handlers. So
there's no way to make one a higher priority than the other. This is a
tough problem. If you have two shared handlers on the same irq line,
and think you can make one a higher priority than the other, you
Hello Steven,
Perhaps adding in a new command line interface (We may need to extend the
command line size limit). Where one could do
irq_priority_map=10-51,21-40,... Where the first number is the irq number
followed by the irq priority. We can also do something similar to
softirqs.
Would
Hello Darren, Juergen and Ingo,
All I need is one IRQ at priority 51, all other can still run at 50. And I
don't want to search at system's runtime for the right PID of driver's
thread to set its priority via chrt. There is no user at this system, its
an embedded one.
It seems
