[PATCH 22/25] lib/cobalt: ticks: drop cobalt_read_hrclock()

From: Philippe Gerum As we move away from the representation of time based on hardware clock ticks, keeping cobalt_read_hrclock() makes no sense anymore. This was an internal, undocumented service returning the hardware TSC value for the platform. The log of commit #d584a57 which introduced it

[PATCH 00/25] Dovetail integration, next round

This is just half-way through to one working arch. A split at this at the point libcobalt is refactored for dovetail ticks. Test target for this part remains I-pipe, i.e. the check for no regressions on it. Jan CC: Hongzhan Chen CC: Philippe Gerum Hongzhan Chen (12): cobalt/irq: dovetail:

[PATCH 03/25] cobalt/intr: dovetail: implement interrupt management, handling

From: Philippe Gerum We are using regular request/free_irq under dovetail. This also means there is no extra task to be done in the interrupt enable/disable services. The affinity hint set during request needs to be cleared before freeing the IRQ, or Linux will complain. Signed-off-by:

[PATCH 18/25] cobalt/timer: pipeline: abstract handling of ONESHOT_STOPPED mode

From: Hongzhan Chen It adds a way to force the timer management code to reprogram the hardware on option, to make the real device controlled by the proxy tick again as it leaves the ONESHOT_STOPPED mode. The I-pipe does not require any further action in this case, leading to a nop.

[PATCH 25/25] lib/cobalt: dovetail: use clock_gettime() vcall for reading timestamps

From: Philippe Gerum Dovetail enables out-of-band access to the vDSO-based clock_gettime() vcall from applications. If present, select this method instead of relying on the hardware tick counter for CLOCK_MONOTONIC, CLOCK_MONOTONIC_RAW, CLOCK_REALTIME and CLOCK_HOST_REALTIME. At binding time,

[PATCH 02/25] cobalt/kevents: dovetail: drop call to obsolete force_commit_memory()

From: Philippe Gerum A process is now marked for COW-breaking on fork() upon the first call to dovetail_init_altsched(), and must ensure its memory is locked via a call to mlockall(MCL_CURRENT|MCL_FUTURE) as usual. As a result, force_commit_memory() became pointless and was removed from the

[PATCH 23/25] lib/cobalt: dovetail: allow representing time as count of nanoseconds

From: Philippe Gerum When the core runs on top of Dovetail, all time values are represented as counts of nanoseconds, in which case a Cobalt tick equals a nanosecond. Introduce inline wrappers for tick-to/from-ns conversion which are nops in the latter case. Cobalt passes us a null clock

Hi Philippe, first, is source.denx.de/Xenomai/xenomai4/linux-evl.git already replacing git.evlproject.org/linux-evl.git? At least CI is currently stuck over the latter [update: was stuck, it's moving again]. Regarding 5.10, I think we are getting closer to the point where our users also need a

Hi Philippe, https://source.denx.de/Xenomai/xenomai/-/commit/dd9a5ee0ed6f734f40d3733f9fff23394c8647bd Bug fix unrelated to dovetail? There is no description, so I cannot easily asses this. Jan
