ipipe: IRQ not received on i.MX8 (linux-imx)

Hi, For a client project I try to port Xenomai 3.1 + I-pipe to the kernel linux-imx 5.4.70 for arm64 (i.MX8 Mini). I adapted the I-pipe patch (5.4.72-arm64). The kernel boots and works well. However, for the non-regression test, I run a client test that uses Xenomai and UDD (to register a PC

[PATCH 6/9] cobalt/select: Add proper handling of EADV

From: Jan Kiszka Since rtdm_fd_select started to return EADV for unknown fds (2db562ad62ec), we were returning that code to applications in case a selector had been allocated for the caller already. That was because libcobalt lacked handling of this error. This fixes it and also establish proper

[PATCH 1/9] cobalt/posix/io: Remove unneeded special case of select_bind_one

From: Jan Kiszka Already at the time of introduction (8ac3db811d21), -ENOENT was not returned by any sane function behind rtdm_fd_select(). Today rtdm_fd_select() officially only returns -EBADF or -EINVAL. By now it also returns -EADV, via rtdm_fd_get() or a default select handler. The only remai

[PATCH 5/9] cobalt/rtdm/fd: Fix default handler setups

From: Jan Kiszka 2db562ad62ec had a point in avoiding EBADF for file descriptors that are not under RTDM management. But it unfortunately got a lot of other cases wrong along this. This one is about returning the right error code if an RTDM driver does not implement a particular handler. That mu

[PATCH 9/9] cobalt/posix/io: Unify native and compat versions of select

From: Jan Kiszka Rather than duplicating lots of code for the sake of compat userspace accesses, provide a common version that is given a flag to decide whether to take the compat or regular code paths. This also brings restart support to the compat selection version which was forgotten by 36132

[PATCH 8/9] cobalt/posix/compat: Privatize sys32_get/put_fdset

From: Jan Kiszka There is no use for this outside of the core that implements select. So stop exporting these helpers. As there are no users outside, simplify their return value on success to 0 because their callers do not care about more. Signed-off-by: Jan Kiszka --- include/cobalt/kernel/co

From: Jan Kiszka The I-pipe implementation was lucky in its approach to not wake up the RT thread in case the non-RT part migrated to an unsupported CPU. For unclear reasons, the scheduled cancellation made it to the thread and avoided any lockup. On dovetail, this fails. So switch both implemen
