Hello, I just installed xenomai 2.5.5 on a 2.6.35.7 kernel and I'm noticing serious regressions on analogy basic features:
1. Buffer management is badly broken. It is not possible to run any acquisition command that wraps around in the ring buffer. That can be simply reproduced with: cmd_read -v d analogy0 -s 0 -S 0 after a while it will fail with: "cmd_read: a4l_read failed (ret=-32)". In dmesg the driver reports: "Analogy: MITE: DME overwrite of free area". 2. Buffer is kept memory mapped after the mapping process dies. If a process mapping a device buffer dies before un-mapping the buffer, it is not possible to reconfigure the bnuffer. a4l_set_bufsize fails with error code 32 and dmesg read "Analogy: a4l_ioctl_bufcfg: please unmap before configuring buffer". Sinche the mapping process died I do not know how to do this. When I proposed some easy changes to the analogy API, to make it much less confusing with trivial changes, Alexis expressed concerns about API stability. What about functional stability? I think the reported ones are major problems easily catch with simple pre-release tests...
