Andrew Tridgell 4e799be144 AP_Scheduler: use fill_nanf() on each scheduler function 2020-02-05 10:10:37 +11:00
Andrew Tridgell ae4bcf0f6f AP_Scheduler: cope with high CPU load by stretching loop times 
this adds an extra budget of time per loop when we are not achieving
scheduled tasks at a rate of at least 1/8 of the desired rate. This
fixes an issue where a vehicle can become uncontrollable if the user
asks for a SCHED_LOOP_RATE which is not achievable. As these events
happen we add extra loop budget until we are able to run all tasks. We
drop the extra time when the CPU pressure eases.

Andrew Tridgell 491715bec7 AP_Scheduler: added get_last_loop_time_s() 
this gives compatibility with previous G_Dt in copter

Andrew Tridgell f436901517 AP_Scheduler: fixed perf info to match previous behaviour 2018-02-13 17:15:05 +11:00

Andrew Tridgell 24d6493453 AP_Scheduler: make loop times cover INS wait_for_sample 
this matches past behaviour, and gives much more useful information to
a user wanting to know if their board it meeting its desired loop rate

Peter Barker 4909000441 AP_Scheduler: implement loop() 2018-02-13 17:15:05 +11:00
Andrew Tridgell 8dcf89b2b7 AP_Scheduler: put scheduler debug on console 2018-02-08 17:36:33 +11:00
Andrew Tridgell 8b0e9bcff4 AP_Scheduler: use pre-computed loop constants 
this prevents changing the loop rate without a reboot. Too many
subsystems rely on a consistent loop rate to allow it to be changed
 2018-01-20 15:35:58 +11:00
Andrew Tridgell 44dd079cb9 AP_Scheduler: allow for loop rates above 400Hz 
with ChibiOS we can run copter at 1KHz with no scheduling misses. This
small PR allows that to be configured.

Peter Barker b445313bf1 AP_Scheduler: remove loop-period argument from load_average 
This now comes from a parameter rather than being hard-set
in the vehicle code

Also adds a method returning the max loop period based on the
loop rate
 2017-08-01 19:39:27 +01:00
Andrew Tridgell 56aa467d60 AP_Scheduler: adjust debug levels 
this is more useful for performance analysis of scheduler, using perf
command

jaxxzer ccb6434831 AP_Scheduler: Set main loop rate to 400hz for Sub 2017-02-21 11:26:14 +11:00
Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers 
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

murata 7721290160 AP_Scheduler:time_available value type invalid uint16_t to valid uint32_t. 2016-07-25 20:18:16 -03:00
Andrew Tridgell 63d0c040e4 AP_Scheduler: expose loop rate on all builds 
as discussed with Randy

Andrew Tridgell fb4cdafef8 AP_Scheduler: allow SCHED_LOOP_RATE for copter in SITL 
very useful for slow simulation environment
 2016-06-17 15:01:18 +10:00
Andrew Tridgell ced4cce358 AP_Scheduler: added optional perf counters at SCHED_DEBUG >= 4 2016-04-21 16:45:02 +10:00
Andrew Tridgell cc25575b3a AP_Scheduler: prevent a startup crash in autotest for Rover 2016-01-05 16:31:06 +11:00
Andrew Tridgell c3829dfb64 AP_Scheduler: allow for arbitrary loop rates 
it turns out 300Hz is pretty useful as it allows for triple EKF on
pixhawk

Lucas De Marchi eb9fd96d5c AP_Scheduler: remove trailing whitespace 2015-12-27 15:58:12 -02:00
Lucas De Marchi 3375b6b01c AP_Scheduler: stop using Progmem.h 2015-12-27 15:58:12 -02:00
Andrew Tridgell 1b1be7e4a2 AP_Scheduler: switch to Hz based scheduler config 2015-12-27 14:57:06 +09:00
Caio Marcelo de Oliveira Filho 81186e5416 AP_Scheduler: use millis/micros/panic functions 2015-11-20 12:34:17 +09:00
Lucas De Marchi 5244559010 Minimize AP_Progmem.h includes 
Most of AP_Progmem is already gone so we can stop including it in most
of the places. The only places that need it are the ones using
pgm_read_*() APIs.

In some cases the header needed to be added in the .cpp since it was
removed from the .h to reduce scope. In those cases the headers were
also reordered.

Lucas De Marchi 20c6ffc5e3 Replace use of UARTDriver::printf_P() with UARTDriver::printf() 
This also starts to show warnings on places that were already using
wrong printf format strings.

Lucas De Marchi 831d8acca5 Remove use of PROGMEM 
Now variables don't have to be declared with PROGMEM anymore, so remove
them. This was automated with:

    git grep -l -z PROGMEM | xargs -0 sed -i 's/ PROGMEM / /g'
    git grep -l -z PROGMEM | xargs -0 sed -i 's/PROGMEM//g'

The 2 commands were done so we don't leave behind spurious spaces.

AVR-specific places were not changed.

Lucas De Marchi 2c38e31c93 Remove use of PSTR 
The PSTR is already define as a NOP for all supported platforms. It's
only needed for AVR so here we remove all the uses throughout the
codebase.

This was automated with a simple python script so it also converts
places which spans to multiple lines, removing the matching parentheses.

AVR-specific places were not changed.

Gustavo Jose de Sousa 53b5b70960 AP_Scheduler: use also task name besides the id for logging 
This makes it easier to identify for which task a log line is.
