Andrew Tridgell f1c6538f34 AP_HAL_Linux: use NEW_NOTHROW for new(std::nothrow) 2024-06-04 09:20:21 +10:00
Richard Allen bf1d364201 HAL_Linux: reduce delay(ms) jitter 
Fix delay(1) rarely returning immediately.
On my RPi4, this once per 5-20k calls that worked.

Reduce the last call to microsleep according to the
remaining time needed in the last loop iteration.

Patrick José Pereira 248daa85a1 AP_HAL_Linux: Scheduler: Use pthread_* over sched_* calls for setschedparam 
musl implements `sched_*` following the posix standard,
where `sched_setschedule` is used for process scheduling.
Linux implementation defines `sched_*` functions based in
the thread scheduler and not with the process.

Using `pthread_*` should be used to follow such standard.

Ref: https://pubs.opengroup.org/onlinepubs/9699919799/

From: https://www.openwall.com/lists/musl/2016/03/01/5

This can be fixed by using `pthread_setschedparam` and requesting the current
thread id via `pthread_self`.

Lucas De Marchi d2446e1219 AP_HAL_Linux: use Thread abstraction to create thread 
The open coded version has the same problem fixed by Thread abstraction:
the order of the calls matters and it's easy to call in the wrong order.
Here pthread_attr_setschedparam() and pthread_attr_setschedpolicy()
should be swapped, like in 62c2f737d5 (AP_HAL_Linux: fix setting RT priorities.)

Lucas De Marchi 7ba82ff23a AP_HAL_Linux: remove raspilot 
It's not being sold, there are just a few (different) engineering

that were pushing it.

Lucas De Marchi 93a558ce5c AP_HAL_Linux: do not call delay callbacks on other threads 
If a thread other than the main one calls Scheduler::delay() we could
end up triggering the call of delay callbacks. Those should only ever
happen on the main thread.

Lucas De Marchi e803045d1f AP_HAL_Linux: Scheduler: increase stack for scheduler threads 
RPI-based boards that use RCInput_RPI need more stack space otherwise we
end up with stack corruption. This leads to crash particularly when also
using GPIO_RPI since it may change what that driver is poking on memory.

This increases stack size to 1M which is overkill for most of other
boards with a more controllable stack usage. However this exposes that
on multiple different HWs a single point for stack size decision may not
be the best.  This can be improved in future.

Ralf Ramsauer 530d3230df Linux: Scheduler: don't ignore return values 
Several return values in the constructor of the scheduler were ignored
before, while they should be respected.

I found that bug while strac'ing ardupilot as it failed at some later
point.
