Fix function-name misspelling (#443) 
If "init tty" is `_inittty` then "reset tty" ought to be `_resettty`

Fix wrong format string in alarm_pool_dump_key (#437)

Optional feature to get the max level that has ever been held by a queue (#444) 
I'm using this in my program to get a better idea of how many entries I
need to allocate to avoid blocking or losing data, and to debug performance
issues.

Fixup divider save_restore for floating point too; improve tests (#405) 
- The divider state needs to be saved for __aeabi_ddiv, __aeabi_fdiv, __aeabi_dtan and __aeabi_ftan or they won't work in interrupts *(probably not used much youd hope), or on an RTOS context switch
 - Refactored code out for the integer and floating point cases
 - Improved the floating point 'tests' in passing to check more return values against GCC implementations
 - Added floating point usage to the IRQ nesting test case

Add basic CMSIS core headers (#384) 
Adds a new cmsis_core INTERFACE library, which provides the basic CMSIS macros/definitions, and RP2040.h and system_RP2040.h
By default the isr_ methods in the vector table are renamed to their CMSIS versions, but this can be overridden by defining PICO_CMSIS_RENAME_EXCEPTIONS=0

allow setting exception handler to the same value, as this might happen if exceptions are set dynamically on both cores, but VTOR is the same... this should indeed cause an error if the values differ, but not otherwise (#385) 2021-05-11 10:34:41 -05:00

Rework ordering of cmake, so that libraries in subdirectories can add to internal lists as PICO_SDK_POST_LIST_FILES, PICO_CONFIG_HEADER_FILES etc. (#382) 
Move generation of config header later, so it gets to include all values for PICO_CONFIG_HEADER_FILES

    implementations to replace WFE/SEV with something more appropriate

add PICO_DIVIDER_DISABLE_INTERRUPTS flag which makes PICO_DIVIDER disable interrupts around division rather than using co-operative guards to protect nested use (i.e. within IRQ/exception). Use of this flag can simplify porting of RTOSes but with a different performance profile (#372) 2021-05-04 07:48:07 -05:00
