cobalt/syscalls: allow for handing over mode selection to syscall handlers
Specific system calls may benefit from dealing with the caller's
runtime mode by themselves, depending on internal information which
the generic syscall dispatcher does not have access to.
To this end, a new syscall mode called "handover" is
introduced. Syscalls bearing this mode bit are always entered from the
current calling domain. The syscall handler may return -ENOSYS to
trigger a switch to the converse domain until all domains have been
visited once, at which point the syscall fails with -ENOSYS
automatically.

lib/cobalt: use lazy schedparam propagation
Do not switch to secondary mode upon schedparam updates for
propagating changes to the regular kernel, if the caller runs in
primary mode when entering pthread_setschedparam*() or
sched_setscheduler(). In such a case, the update request to the
regular kernel is left pending until the target thread resumes
execution in relaxed mode, at which point it is committed.
CAUTION: This mechanism won't update the schedparams cached by the
glibc for the caller in user-space, but this is the deal: we don't
relax threads which issue pthread_setschedparam[_ex]() from primary
mode anymore, but then only the kernel side (Cobalt and the host
kernel) will be aware of the change, and glibc might cache obsolete
information.
If the caller already runs in relaxed mode on entry to these services,
the update request takes place immediately, via the regular (g)libc
calls.
In any case, the new scheduling parameters for the target thread are
immediately applied by Cobalt, regardless of the update path followed
for the regular kernel.

cobalt/thread: add schedparam lazy propagation
Provide a mechanism for carrying out a lazy propagation of schedparam
updates to the regular kernel, so that userland does not have to
switch to secondary mode for this.
When userland issues sc_cobalt_thread_setschedparam_ex for updating
the scheduling parameters of a Xenomai thread, a request for
propagating this change to the regular kernel is made pending. Such
request will be committed later, either when:
- the thread relaxes if it is running in primary mode when the update
request is received;
- next time the thread calls back into the Cobalt core as a result of
receiving a HOME action from a SIGSHADOW notification, which is sent
if such thread was relaxed at the time of the update request.
As a result, the target thread will have propagated the schedparams
update to the regular kernel as soon as it resumes (relaxed) execution
in user-space.

cobalt/powerpc: drop support for unlocked context switch
This feature never actually brought any measurable gain on powerpc
platforms, compared to the complexity of its implementation in the
pipeline. It was primarily aimed at reducing latency for interrupt
handlers when costly cache and TLB flushes are required to switch
context, at the expense of increasing the scheduling latency. It
turned out to be counter-productive on common powerpc platforms, with
efficient MMUs.
This feature has been default off for a while now, and 4.1+ pipelines
won't provide support for it anymore. Time to drop support from
Xenomai too.

cobalt/arm64: Use empty mayday implementation for arm64.
The arm mayday implementation was not correct for arm64. Replace with empty
implementation.
Handle mayday in the linux domain, using xnthread_relax. This change is
essentially the same as the general change proposed in the 'Mayday issues
again' discussion (Jan Kiszka, Jun 21), though only applied to arch/arm64.

cobalt/arm64: restrict unlocked switch to SMP
Unlocked switching for Xenomai/ARM was specifically introduced for
improving the interrupt latency on low-end armv4/armv5 platforms with
VIVT caches.
The once massive overhead imposed on the MMU context switching code
for invalidating the cache is long gone with VIPT indexing, and
keeping IRQs off while switching the memory context on armv8 these
days is not an issue. Actually, the complexity of the code involved in
dealing with unlocked switching may overbalance the expected gain.
However, the mainline kernel implementation for ASID management in the
SMP case currently requires us to keep IRQs enabled when allocating a
new MM context over the Xenomai domain, just like it did for aarch32
during the 2.6.3x time frame until the IPI-based approach was
eventually dropped.
So, let's restrict unlocked switching to the SMP case, forcing it off
otherwise, in the hope we can drop it entirely in the future.
At this chance, CONFIG_IPIPE_WANT_PREEMPTIBLE_SWITCH moves to the
kernel area, where it actually belongs.

cobalt/arm64: fix build for mismatched printf type (%lx,u64) on arm64.
pc and orig_r0 are u64 on arm64 and 'unsigned long' or arm and other
platforms. printf referencing these are using %lx. On arm64, long and long long
(and u64) are 64 bits. Rather than changing printf format, chnage arm64 macros
to cast to unsigned long.

boilerplate/bootstrap: do not override main() in PIC mode
The PIC version of the bootstrap module is intended to be part of
shared libraries which want to enable Xenomai's auto-init feature when
loaded (i.e. dlopened).
Therefore, overriding the main() entry point is meaningless in such
context, assuming the latter should be defined in the main executable
instead.

boilerplate: allow for auto-init of external shared libraries
3rd-party shared libraries for which Xenomai auto-initialization is
required must include a position-independent version of the bootstrap
module.
This means that we need to export a PIC object such libraries can
include, in addition to a non-PIC object to be linked in regular
executables as usual. Such objects are available as
@libdir@/xenomai/bootstrap-pic.o and @libdir@/xenomai/bootstrap.o
respectively.
xeno-config* scripts now accept the --auto-init-solib option to emit
the proper link directives for including the PIC bootstrap module into
shared libraries when --ldflags is given.

cobalt/rtdm: leave mode selection to I/O syscall handlers
We don't want requests bearing invalid file descriptors (RTDM-wise) to
trigger any mode switch, so that RTDM requests on regular fildes can
be rejected with little overhead.
Tell the core to hand over mode selection to RTDM I/O syscall
handlers, which now check the file descriptor prior to triggering any
mode transition.

cobalt/syscalls: allow for handing over mode selection to syscall handlers
Specific system calls may benefit from dealing with the caller's
runtime mode by themselves, depending on internal information which
the generic syscall dispatcher does not have access to.
To this end, a new syscall mode called "handover" is
introduced. Syscalls bearing this mode bit are always entered from the
current calling domain. The syscall handler may return -ENOSYS to
trigger a switch to the converse domain until all domains have been
visited once, at which point the syscall fails with -ENOSYS
automatically.

cobalt/kernel: use raw_spinlock* API to access IRQ pipeline locks
In order to cope with PREEMPT_RT_FULL, the spinlock* API should be
invoked for regular spin locks exclusively, so that those locks can be
handled by PREEMPT_RT's sleeping lock API seamlessly.
Since I-pipe locks are basically raw locks with hard IRQ management,
sticking to the raw_spinlock* API for them makes sense. The regular
spinlock* and raw_spinlock* APIs can be used indifferently for
manipulating IRQ pipeline locks (ipipe_spinlock_t) with the current
pipeline releases, so this change is backward compatible.

cobalt/thread: fix race on accessing the global thread list
nkthreadq is only used by the /proc interface handlers these days, to
get the list of active Cobalt threads.
Adding an emerging user-space thread to that list should not be done
before it is actually mated to a Cobalt shadow, otherwise the /proc
handlers might find such thread before its host_task pointer is known,
causing invalid memory accesses.
A simple way to reproduce the issue involves running a (user) thread
creation loop while continuously reading from /proc/xenomai/sched/* in
parallel.
The fix postpones the insertion of emerging threads into the global
thread queue until their TCB is fully built.

cobalt/rtdm: add base minor setting for named drivers
Some character/named drivers may want to set a non-zero base minor for
indexing their devices (e.g. GPIO banks).
To this end, the new .base_minor field can be set in device driver
descriptors. Most in-tree driver descriptors reside in static memory
which guarantees that such field is zero when unspecified.
CAUTION: existing out of tree drivers have to initialize .base_minor
explicitly if the descriptor does not reside on clean memory.

cobalt/rtdm: allow setting the kernel device class of a driver
It may be convenient to set the Linux device class for a particular

the attached devices, or using a different hierarchy for the device
nodes (instead of /dev/rtdm).
The new rtdm_drv_set_sysclass() call allows this, provided the
non-default class is set before the first device referring to the
driver is registered by a call rtdm_dev_register().

lib/cobalt: simplify checks for secondary mode
Whether a current thread is currently running in primary/secondary
mode can be checked by inspecting the status of the XNRELAX bit in the
thread's u_window. The lack of u_window denotes a non-Xenomai, regular
thread which for which the current mode is always relaxed.
A thread's handle and its u_window area are tightly coupled: the
latter has to be valid for any thread with a valid handle.
Introduce cobalt_is_relaxed() for testing the current mode, and fixup
all open coded versions of this routine.
In addition, assert_nrt_fast() is marked as deprecated, since
assert_nrt() is not a slow call anymore.

cobalt/timer: allow binding core timers to passive CPUs
Some timers initialized by the Cobalt core may have a valid reason to
live on CPUs excluded from the real-time set. A typical example would
be the host timer from the scheduler slot, which relays ticks to the
regular kernel. Other core timers are just better dealt with when
created and left passive on those CPUs.
Mark all core timers specifically, and exclude them from the LART
detection code in __xntimer_init(). This fixes a spurious Cobalt debug
assertion seen on SMP at boot, when the real-time CPU set is
restricted to a subset of the online CPU set.

cobalt/thread: fix SMP race with xnthread_join()
The situation below would cause a kernel crash on any earlier 3.x
release, with ktask implemented in a dynamically loaded/unloaded
module:
CPU0: rtdm_task_destroy(ktask)
...
rmmod(module)
CPU1: ktask()
...
...
__xnthread_test_cancel()
do_exit()
(last) schedule()
OOPS: prev still treading on stale memory
In this case, the module would be unmapped too early, before the
cancelled task can ultimately schedule away.
The changes also fix a stale reference from the joiner thread to the
former ->idtag field, after the joinee's TCB has been dropped.

cobalt/thread: force secondary mode for joining threads
Make xnthread_join() switch the caller to secondary mode prior to
waiting for the target thread termination. The original runtime mode
is restored upon return.
Since the joiner was already synchronized on an event that may be sent
by the joinee from secondary mode exclusively, this change does not
drop any real-time guarantee for the joiner: there has never been any
in the first place.
This is a preparation step to a stricter synchronization between the
joiner and the joinee, especially in the SMP case.

cobalt/thread: do not demote kthreads when cancelling
There is no point in switching a kthread to weak scheduling when
cancelling it, as it must reach a cancellation point asap as part of
its work loop anyway. Would it omit testing for cancellation, weak
scheduling would not help enforcing the exit request anyway.

cobalt/init: get main heap memory from vmalloc()
There is no reason to ask for physically contiguous memory from
alloc_pages[_exact]() for the main heap: real-time heaps are certainly
no place for getting DMA-suitable buffers from.
Using alloc_pages*() for common Cobalt heaps is a problem:
- this raises the probability of getting allocation failures in case
of memory fragmentation (although seldom at boot time, some
Cobalt-based modules also using such services could fail allocating
their heap later on).
- this restricts the maximum heap size to MAX_ORDER (currently 4Mb),
which may be too small in some configurations.
Therefore, switch from alloc_pages_exact() to vmalloc().

cobalt/registry: return -EAGAIN upon lack of registry slot
-ENOMEM is confusing in this case, does not actually reflect the error
condition, and does not match the error code commonly returned by
POSIX services for denoting a (temporary) lack of resources.
Besides, this source of error was not even mentioned in the
documentation of the affected services.
All error codes must be detected, and any program that might have
specifically checked for -ENOMEM during error recovery in the affected
services was potentially confused, so this change does not introduce a
significant ABI variation.

copperplate/syncobj: fix race in aborted wait_grant/drain operations
Fixup a potential race upon return from grant/drain_wait operations,
e.g. given two threads A and B:
A:enqueue_waiter(self)
A:monitor_wait
A:monitor_unlock
A:[timed] sleep
A:wakeup on timeout/interrupt
B:monitor_lock
B:look_for_queued_waiter
(found A, update A's state)
B:monitor_unlock
A:dequeue_waiter(self)
A:return -ETIMEDOUT/-EINTR
The race may happen anytime between the timeout/interrupt event is
received by A, and the moment it grabs back the monitor lock before
unqueuing. When the race happens, B can squeeze in a signal before A
unqueues after resumption on error.
Problem: A's internal state has been updated (e.g. some data
transferred to it), but it will receive -ETIMEDOUT/-EINTR, causing it
to miss the update eventually.
The fix involves filtering out -ETIMEDOUT/-EINTR errors upon return
from wait_grant/drain operations whenever the syncobj was actually
signaled.

drivers/ipc/xddp: fixup allocation rounding for tiny private pool sizes
With tiny pool sizes specified by userland (< PAGE_SIZE), we may end
up with the streaming buffer consuming all the available pool memory
at once, due to the full page allocation scheme used by the underlying
allocator (size > PAGE_SIZE * 2).
To determine the per-socket pool size, round the user size and the
streaming buffer size separately, before summing the two results, so
that tiny sizes are eventually rounded to PAGE_SIZE.

cobalt/corectl: chain config requests to external subsystems
External subsystems (e.g. RTNet, Analogy) may attach to the generic
corectl() configuration service by registering to the config_notifier
list, using the cobalt_add_config_chain() routine.
Upon a call to corectl(), a configuration request left unprocessed by
the core is posted to the registered handlers in turn, until NOTIFY_OK
or any error is raised. If a request remains unprocessed, corectl()
eventually returns -EINVAL.
Unlike core configuration requests which may be handled in primary
mode if applicable, the current context is always switched to
secondary mode before subsystem handlers are called.

cobalt/timer: avoid early tick in case of overrun
There is a race condition in the current timer code when a timer period
is close to the maximum jitter. It may happen that the next timer
interrupt is already pending while xntimer_get_overruns computes the
count of overruns. In that case, the count of overruns returned to
user-space is one too much, and the application ends up expecting the
next tick one period later than when it will actually happens.
Avoid that problem by advancing the timer in xntimer_get_overruns.

cobalt/clock: introduce CPU affinity for clock event sources
Xenomai clocks may be backed by devices issuing event notifications on
a restricted set of CPUs only. Typically, the interrupt distributor of
GIC-equiped ARM processors is programmed to route shared processor
interrupts to CPU0 by default. For instance, a Xenomai clock paced by
a GPIO input signal would tick exclusively on CPU0 in that
configuration.
We have to make sure that timers are always attached to per-CPU queues
which are expected to receive event notifications from the underlying
clock device, otherwise threads may wait for events indefinitely on
those timers.
Previously, a restrictive assumption was made that all CPUs from the
real-time set should be able to receive events, indirectly assuming
that each ticking device is a per-CPU device. Although this is correct
for the core Xenomai clock based on local timers for SMP, this turns
out to be wrong quite frequently with external Xenomai clocks backed
by common devices issuing a periodic master beat.
To fix this, we require the set of CPUs the event source may tick on
to be declared as part of the Xenomai clock properties. This
information is then used to migrate timers to an appropriate CPU if
need be, and to detect mismatching CPU affinities between timers and
clock devices when DEBUG_COBALT is enabled.

include/boilerplate, lib: do not pull ancillaries.h indirectly
boilerplate/ancillaries.h contains general-purpose macro-definitions
which might conflict with 3rd-party libraries.
Since those definitions are primarily useful to the Xenomai code base,
there is no point in pulling this header in the application namespace
via include/boilerplate/lock.h. Drop this indirect inclusion, and
fixup the client code to include boilerplate/ancillaries.h explicitly
when needed.

testsuite/switchtest: fix mode switches
Since the changes in pthread_setmode_np() API, switchtest threads all
ran in primary mode, fix this by using the cobalt_thread_relax() service
to switch to secondary mode instead of pthread_setmode_np().

cobalt/posix/process: fix mayday mapping denial on NOMMU
Until we stop backing /dev/mem with the mayday page, we can't ask for
PROT_EXEC on NOMMU, since the former does not define mmap
capabilities, and default ones won't allow an executable mapping with
MAP_SHARED. In the NOMMU case, this is (currently) not an issue for
implementing the MAYDAY support.
