Bug#304648: zaptel-source: Fails to enable RTAI support

[Tibor Dekany]

Package: zaptel-source
Version: 1:1.0.7-3
Severity: normal

The zaphfc module can make use of RTAI (Real Time Application
Interface). RTAI is available as debian package containing the source
code for the kernel modules. Those include files are located in
/usr/lib/realtime, and not in /usr/realtime.

To be able to use RTAI with zaphfc, the
/usr/src/modules/zaptel/zaphfc/Makefile has to be adapted according to
the diff below:

--- Makefile    2005-04-03 20:49:19.000000000 +0200
+++ /usr/src/modules/zaptel/zaphfc/Makefile     2005-04-14
14:47:28.000000000 +0200
@@ -12,7 +12,7 @@
 else
  ZAP="-I$(ZAPTELDIR)"
   endif
   -RTAI = $(shell [ -f /usr/realtime/include/rtai.h ] && echo
   "-DRTAITIMING -I/usr/realtime/include")
   +RTAI = $(shell [ -f /usr/lib/realtime/include/rtai.h ] && echo
   "-DRTAITIMING -I/usr/lib/realtime/include")

    HOSTCC=gcc

After this change, when you rebuild the zaptel modules, RTAI support
will be included, if it is installed on the system. On my system, this
reduces the Interrupt load on the hfc card by a factor of 4 (for total
2000 interrupts per second instead of 9000).

Thanks in advance,
greetings,
