Dear Forum, Occasionally I get the warning listed below on my Beaglebone Black console. I am running Debian 3.8.13-bone67 with Xenomai 2.6.4
I am running four RTDM modules handling interrupts from GPIO pins. As far as I have found, this kind of warnings can be associated with inappropriate calls from user space. But I cannot find such calls in my code. The irq is requested by a RTDM kernel module when issuing a device open call from user space. Please advice Best regards Terje Froysa [ 398.167710] RTDM BARO INT (GPIO 60) - open [ 398.167730] RTDM BARO pin 60 - irq number 188 [ 398.167738] RTDM BARO 60 - request GPIO [ 398.167757] RTDM BARO 60 - request IRQ 188 [ 398.167768] ------------[ cut here ]------------ [ 398.172673] WARNING: at arch/arm/kernel/ipipe.c:157 ipipe_set_irq_affinity+0x47/0x70() [ 398.180951] Modules linked in: g_multi libcomposite imu_rtdm(O) baro_rtdm(O) gyro_rtdm(O) rtgps_1pps(O) omap_rng [ 398.191733] [<c00117ed>] (unwind_backtrace+0x1/0x9c) from [<c003022b>] (warn_slowpath_common+0x33/0x48) [ 398.201606] [<c003022b>] (warn_slowpath_common+0x33/0x48) from [<c0030251>] (warn_slowpath_null+0x11/0x14) [ 398.211701] [<c0030251>] (warn_slowpath_null+0x11/0x14) from [<c001470f>] (ipipe_set_irq_affinity+0x47/0x70) [ 398.222010] [<c001470f>] (ipipe_set_irq_affinity+0x47/0x70) from [<c00991b5>] (xnintr_attach+0x21/0x1f0) [ 398.231936] [<c00991b5>] (xnintr_attach+0x21/0x1f0) from [<c00eea8d>] (rtdm_irq_request+0x25/0x44) [ 398.241324] [<c00eea8d>] (rtdm_irq_request+0x25/0x44) from [<bf80c153>] (baro_irq_open+0x6a/0xfc [baro_rtdm]) [ 398.251704] [<bf80c153>] (baro_irq_open+0x6a/0xfc [baro_rtdm]) from [<c00eb531>] (__rt_dev_open+0x61/0xa4) [ 398.261832] [<c00eb531>] (__rt_dev_open+0x61/0xa4) from [<c00eeca9>] (sys_rtdm_open+0x3d/0x48) [ 398.270853] [<c00eeca9>] (sys_rtdm_open+0x3d/0x48) from [<c00a9649>] (losyscall_event+0x81/0x1e0) [ 398.280142] [<c00a9649>] (losyscall_event+0x81/0x1e0) from [<c007d169>] (ipipe_syscall_hook+0x2d/0x34) [ 398.289892] [<c007d169>] (ipipe_syscall_hook+0x2d/0x34) from [<c007bfc7>] (__ipipe_notify_syscall+0x5b/0xb8) [ 398.300180] [<c007bfc7>] (__ipipe_notify_syscall+0x5b/0xb8) from [<c001487d>] (__ipipe_syscall_root+0x3d/0x98) [ 398.310646] [<c001487d>] (__ipipe_syscall_root+0x3d/0x98) from [<c000cbcd>] (local_restart+0x9/0x54) [ 398.320194] ---[ end trace f174ab8361e31708 ]--- Smail: Terje Frøysa, SINTEF ICT (Information and Communication Technology), N-7465 Trondheim, Norway.
