  Hi,
 
  here comes version 2 of the I-pipe patch for the S3C24xx ARM. The
  reported problem is solved, the timer works as expected as far as I
  can see. Linux is still there after insmod'ding the native skin. More
  test results will follow next week after I tortured the new patch with
  the whole testsuite arsenal. ;-)
 
  The patch has got two suboptimal characteristics due to the generic
  ARM I-pipe implementation which I did not want to change during the
  first steps:
 
  1. Regarding the demux of chained IRQs (See [1]). As the S3C24xx has
  more than one chained IRQ there are two consecutive queries for them
  in __ipipe_mach_irq_mux_p() and __ipipe_mach_demux_irq(). This could
  be optimized.
 
  You should use switch/case instead of if else if else if, the generated
  code would be better optimized.

 You can make the test cheap test by using a mask.

Yes, I will do it that way. Thanks!

Sebastian

I lost track somehow. What version of the Linux kernel, ADEOS-IPIPE and 
Xenomai are you using?


Thanks.

Wolfgang.
