Real Time Signals In PowerPC Linux

Real Time Signals In PowerPC Linux

[Deepak]

Its regarding realtime signals support in powerpc port of linux. Though
Real-Time signals are supported for Intel i386 port no such support is
available for powerpc port
Anyone having idea about any existing patch for real-time signals in
powerpc linux(linux kernel 2.4.20)

What are you talking about ? All architectures have RT signals afaik...

hi

  Well I did "kill -l" in linux (v2.4.20) installed on a powerpc board
  and it listed only 32 signals, SIGRTMIN to SIGRTMAX were missing

Well, I don't know what's up with that kernel you are using, it works
fine here on 2.6.12 but I'm fairly sure it worked with 2.4.20 too. Maybe
a glibc or a kill version issue ?

Yes It was indeed the issue of kill command version. I tried sending
SIGRTMAX to a process using kill() and sigqueue() , both of them worked
though 'kill -l' was still showing 32 signals.
