Security Issues Fixed In This Release
Compatibility Concerns
| Markdown |
|---|
* [#10605](https://github.com/apache/nuttx/pull/10605) Implement ticket spinlock
A proposal to slove #1488
Implement ticket spinlock.
* [#10861](https://github.com/apache/nuttx/pull/10861) spinlock: Add spin_lock_init and spin_is_locked macro
align with Linux api naming.
* [#11102](https://github.com/apache/nuttx/pull/11102) sched: explicitly select the cpuload clock source configuration
Different configurations require different dependencies.
Explicitly select dependencies to avoid automatically selecting
inappropriate configurations.
* [#11334](https://github.com/apache/nuttx/pull/11334) stm32h7_adc: Dynamically set clock prescaler and BOOST
First commit is aligning naming and is a breaking change.
* [#10827](https://github.com/apache/nuttx/pull/10827) Improve adjtime() functionality
Prior pull request #9084 and issue #8858 added basic adjtime()
support for the SAMv7 platform.
This pull request adds support for STM32 platform.
In addition I have made a few changes to the adjtime() configuration
options:
1) Previously adjustments less than 1 microsecond per tick would be
completely ignored. Now they are applied over a shorter period at
a rate of 1 us per tick.
2) Previously CLOCK_ADJTIME_PERIOD was in units of 1/100th of second.
Change to milliseconds to be more generally useful unit.
Change setting name to CLOCK_ADJTIME_PERIOD_MS to make the unit change
easier to notice.
3) Previously CLOCK_ADJTIME_SLEWLIMIT was in percentage.
Most clock crystals have better accuracy than 1%, so the minimum slew
rate was excessive. Change to CLOCK_ADJTIME_SLEWLIMIT_PPM with setting
value in parts per million.
4) No need to use floating point math in clock_adjtime.c.
Impact
Users who have used CLOCK_ADJTIME_PERIOD and CLOCK_ADJTIME_SLEWLIMIT
settings should update their configuration. New CLOCK_ADJTIME_PERIOD_MS is
10x the old period value, and new CLOCK_ADJTIME_SLEWLIMIT_PPM is 10000 times
the old slewlimit. |
